The Tendency of Referencing to AOAC Methods in TCVNs, QCVNs and Harmonizing TCVNs in the Food Chain According to the AOAC Methods
Trieu Viet Phuong
Vietnam Standards and Quality Institute
Abstract
By the end of 2022, Vietnam’s standard system (TCVN) has 2,026 national standards related to the food chain (food and feed), of which the number of test method standards accounts for nearly 70%. It can be said that the test method plays an extremely important role in the food chain. The harmonization of TCVN on test methods for the food chain according to international standards (ISO standards) is always a priority in the process of developing and perfecting the TCVN system. However, besides that, there are also many TCVNs built on the basis of harmonizing (referencing) methods of the International Association of Official Analytical Collaboration (AOAC International).
This review report analyzed a number of cases in which the AOAC method is referenced in the national standards and national technical regulations of Vietnam; the harmonization of national standards according to the AOAC method and the use of the AOAC method in a number of public and non-public laboratories. From the above analysis results, it is possible to make comments about the trend of using AOAC method in testing activities in Vietnam.

Ensure Food Safety by Rapid Food Pathogen Testing in Probiotic Infant Nutritionals
Andrew Lienau
MilliporeSigma
Abstract
Infant nutritional products are a rapidly growing market in Southeast Asia (SEA). Often probiotic organisms are added to infant products to provide support for the healthy development of infants. The presence of two pathogenic organisms, Salmonella and Cronobacter, have caused recalls in SEA for infant formula. The use of probiotic organisms can create challenges to food safety to allow rapid detection of potential contaminating pathogenic organisms.
This session will highlight the use of probiotics in infant nutritionals. It will discuss the challenges of rapid molecular detection of Salmonella and Cronobacter, as examples for key factors to consider for development of robust methodology to ensure distribution of safe infant foods.

Status of Adoption of AOAC Methods in ISO 17025 Accredited Laboratories in Vietnam
Ms. Hoang Thanh Duong
Head of Testing Accreditation Division
Bureau of Accreditation (BoA), Vietnam
Applying the AOAC Method to Food Testing at Accredited Laboratories in Vietnam
Hoang Thanh Duong
Bureau of Accreditation (BoA), Vietnam
Abstract
Bureau of Accreditation (BoA) is the Science and Technology Organization set up under the Ministry of Science and Technology established in 1995 by the Minister of Ministry of Science and Technology (The Decision number 1926/QĐ- TCCBKH dated 10 November 1995) to carry out accreditation activities for testing and calibration laboratories, inspection bodies, and certification bodies.
By the middle of 2023, BoA has accredited more than 1500 laboratories and of which the number of laboratories in the field of Chemical, Biological, and Pharmaceutical accounts for more than 70%. Food, feed, supplement, and pharmaceutical laboratories account for more than 40% of all accredited laboratories.
The current reality of using test methods for testing criteria in food and feed laboratories is mainly that TCVN, AOAC, ISO standards, and almost of Vietnamese standards are harmonized with ISO and AOAC. However, the use of AOAC test methods by laboratories also depends on many factors such as the scope of application of the method, conditions for method implementation, implementation techniques, information on validation data, technical regulation of Vietnam, and customer requirements.
Currently, many technical regulations of Vietnam specify test parameters for food and feed products and refer to the AOAC test method, so the harmonization of the application of AOAC standards has been promoted, however, the percentage of test criteria cited by the AOAC method is still not much and sufficient for all kinds of food and animal feed products.

Challenges with Total Sugar Analysis.
Sean Austin, Erik J.M. Konings
Nestlé Research, Nestlé Institute of Food Safety and Analytical Sciences, Lausanne, Switzerland.
Abstract
The definition of “sugars“ described in the Codex Standard on Nutrition Labeling (CXS2-1985) and almost universally applied is “all mono- and disaccharides”. Confusion arises when certain nutritional guidelines talk about “added sugars” and “free sugars”. A single analytical method to tackle more than 100 compounds referring to the definition of all mono- and disaccharides is an impossible task. A pragmatic approach to sugar analysis is to select a method that determines the content of the sugars that are commonly found in food. That list is more manageable and includes glucose, galactose, fructose, sucrose, lactose and maltose.
There are many (Official) methods available for the analysis of sugars in different products. This presentation gives an overview of the available technologies and example (Official) methods. Selection of the method may depend on the specific food product to be analyzed. There are also certain methods which should not be generally applied for total sugar analyses. Finally, results will be shown for the analysis of total sugars in a food product by different Labs in Vietnam.

Abstract
Heavy metals are known to be harmful to most forms of life when present in too high quantities. The accumulation of heavy metals over a protracted period may have a variety of negative impacts. In order to limit the quantity of potentially harmful heavy metals that may be found in food, governments in each nation have enacted legislation setting maximum levels. In Vietnam, food safety actors must comply with national standards and technical rules stipulated in the Food Safety Law. Several Vietnamese food safety standards and criteria have been harmonized with international Codex standards. The permissible level of heavy metal contamination in food is specified in the National Technical Regulation QCVN 8-2:2011/BYT. This law sets the maximum allowable levels of contamination in food that may include arsenic, cadmium, lead, mercury, methylmercury and tin. Metals in food contact materials and packaging are regulated by QCVN 12-1:2011/BYT, QCVN 12-2:2011/BYT, QCVN 12-3:2011/BYT, and QCVN 12-4:2015/BYT. These standards apply to plastic, rubber, metallic, glass and ceramic materials. These laws provide revised procedures for both sampling and detection. Other Vietnamese standards and technical regulations on food safety also require the relevant actors to follow standards of, for example, QCVN 6-1:2010/BYT for bottled/packaged natural mineral waters and drinking waters, quality of clean water used for domestic purposes by QCVN 01-1:2018/BYT.
The leading laboratories in food and environmental testing in Vietnam are required to obtain ISO 17025:2017 certification and the approval of the relevant governmental authorities to guarantee that analytical results are always the most reliable and maintain the capacity of the laboratory. These laboratories can analyze most metals contained in food, feed, and environmental samples to ensure that they comply with national and international regulations because they are equipped with modern equipment such as ICP-OES, ICP-MS, LC-ICP-MS, techniques GF-AAS, F-AAS, CV-AAS, HG-AS for heavy metal testing and a team of experienced technicians who develop methods.

Rapid Detection, Qualitative and Quantitative Analysis of Banned Chemical Substances Added in Dietary Supplements in Vietnam
Mr. Phan Nguyen Truong Thang
Head of R&D Department
Institute of Drug Quality Control, Ho Chi Minh City (IDQC-HCMC), Vietnam
Abstract
Since the 2000s, at the beginning of the millennium, a number of non-steroidal anti-inflammatory drugs have been discovered in Vietnam (aspirin, acetaminophen, diclofenac, indomethacin…), corticoids (dexamethasol,betamethason, prednisolone…), anti histamines (cyprohaptadin), or sibutramine… had been illegally added into traditional medicines, including domestic products and products originating from some Southeast Asian countries (Malaysia, Singapore, Cambodia… ) and China.
By 2007-2010, in the National Institute of Drug Quality Control (NIDQC), a series of dietary suplements and traditional medicine for men containing PDE-5 (phosphodiesterase type 5) inhibitors were detected, such as: sildenafil, tadanafil, vardenafil and many sildenafil analogues (sildenafil homologues: nor-acetyldenafil, acetyldenafil, sulfosildenafil, sulfoaidenafil, hydroxy- homosildenafil) as well as some functional food products, herbal medicines containing pharmaceutical ingredients diabetes (metformin HCl, gliclazide, glibenclamide). In 2018, Hanoi and Ho Chi Minh City Hopitals received many emergency patients, including some deaths due to the use of dietary supplements to treat diabetes. The Institute Drug Quality Control in Ho Chi Minh city (IDQC HCMC) has discovered that some traditional medicine (TCM) and dietary supplements contain metformin and phenformin, they were major cause of acidosis leading to death. Currently, traditional drugs and dietary supplements derived from medicinal herbs mixed with substances with hypoglycemic effects tend to increase and are not controlled. This greatly affects the health of users and causes unwanted effects. In HCM City, we develop the methods for rapid detection, qualitative and quantitative analysis of a banned chemical substances added in dietary supplements in Vietnam, focusing on the above-mentioned groups. The development of classical to modern procedures for analyzing these groups of banned substances has become a tool to quickly and accurately detect the illegal mixing of modern drugs in health foods and traditional medicines. The methods used today are mainly sample preparation, systems of chromatographic methods TLC, HPLC – PDA and LC MS/MS. Most recently, we used 1H-NMR and 1H-qNMR to analyze, detect, qualitative and quantitative functions of these substances contained in the mentioned products. We hope that the existing system of analytical methods will contribute to helping managers control food safety, not only with the above mentioned health protection foods, but also with other foods, protect consumers and protect people’s health.

Nitrosamines – Analytical Methods and Risk Assessment in Vietnamese Food
Nguyen Thi Hong Ngoc, Tran Cao Son, Bui Cao Tien, Vu Ngoc Tu
National Institute for Food Control (NIFC), Vietnam
Abstract
Nitrosamines are a group of substances formed in foods due to chemical interactions, but mainly through food processing. Many substances in this group are rated 2A and 2B by the International Agency for Research on Cancer (IARC) for their potential carcinogenicity to humans. They are a cancer factor onsets to many different body areas such as the stomach, esophagus, pancreas, and lungs. Currently, there are only regulations on the maximum content of nitrosamines in drinking water, there are no regulations for food globally. Therefore, risk assessment for nitrosamines is necessary. Risk assessment is the most important component of risk analysis, and is the scientific foundation for risk management and communication. In order to provide analytical data and a basis for making management decisions, the assessment will start with the analysis of the exposure of nitrosamines in food, combined with the investigation of food consumption, thereby calculating dietary exposure to the target foods, then estimating and evaluating risk at exposure levels. In Vietnam, the National Institute for Food Control has been conducting risk assessment studies related to nitrosamines since 2018 to date, including developing analytical methods on common Vietnamese foods: meat, poultry, seafood, eggs, dried food, fermented food, and other ready-to-eat food; combined with a food consumption survey starting from Hanoi and surrounding areas; expanded to a larger scale than the whole country, with the goal of having data set to help management agencies inspect and monitor food quality safely and effectively, and have timely risk communication to consumers.

Nutrition Labeling
Tolerance Limits for Nutrient Declaration and Claims
Dr. E Siong Tee
Nutrition Consultant
Tolerance Limits for Nutrient Declaration and Claims
E-Siong Tee
TES NutriHealth Strategic Consultancy, Malaysia
Abstract
Regulatory authorities conduct regular surveillance programmes to check on compliance of values of nutrients declared for nutrition labelling and nutrition claims. Enforcement actions may be taken on values that do not comply with the labelling and claims regulations. It should be acceptable that such enforcement cannot be exactly at the values obtained upon analysis of the food product. Certain amount of tolerance should be permitted between the analysed and declared values. However, the content of nutrients should not deviate substantially from labelled values to the extent that could lead to consumers being misled. There must be a limit to the permitted tolerances. This presentation discusses what are tolerance limits, why such tolerances are needed and how the regulatory authorities in some countries in Southeast Asian countries set these limits.
Tolerances limit refers to the acceptable differences between the nutrient values declared on a label and those prescribed in the regulation. The ratio between the nutrient level derived by analytical testing and the label value is calculated to determine % tolerance: laboratory value / label value x 100 = % tolerance. This % tolerance is then compared with the permitted limit of tolerance set by the relevant regulation. Most often, different tolerance limit is set depending on the purpose of the regulation, ie for nutrient labelling or claims purposes.
In setting tolerance limits, several factors that are known to affect the nutrient analysis results must be taken into consideration. These factors include variations in the analytical methods; variations in ingredients /raw materials used in a product, especially natural ingredients; and stability or changes in nutrient levels in ingredients and products over time. The approaches used by United States of America, Malaysia, Indonesia, Philippines, Singapore and Thailand in regulating permitted limits of tolerances are summarised in the presentation. Different criteria for compliance was also set up for different type of regulations, ie whether the nutrient content label is for declaration or claims purposes. There are some general similarities but significant differences exist.
Reviewing the approach in the countries, it can be seen that there is no uniform approach towards regulating permitted tolerances limits. Different terminologies are also used by countries. Efforts to harmonise approaches in tolerance limits in Southeast Asia is encouraged to facilitate international trade. Several challenges in enforcement have been identified in countries in the region. For example, laboratory capabilities vary greatly among in the region, inter laboratory variations are large; there is a lack of inter-laboratory studies. Countries also lack experiences in enforcement of compliance with nutrient declaration and claims. It is more important to give emphasis to enforcement of health claims which can mislead consumers. It is also suggested to give emphasis to compliance with NIP formats rather than the actual values as nutrition labelling is still a relatively new regulation in the region. There should be more opportunities for discussions and exchange of experiences in use of tolerance limits in SEA, including analytical methods for nutrients and programmes to improve laboratory precisions.

Abstract
The rising global demand for probiotic products has led to an increased need for robust testing methods to verify their composition, strain identity, viability, and contaminants. The conventional testing methods are inadequate to meet the growing demand for testing in global trade. In response to these challenges, next-generation sequencing (NGS) has emerged as a promising tool for probiotics testing. Recognizing the importance of addressing these issues, Asia-Pacific Economic Cooperation (APEC) and University of Malaya, Malaysia are supporting the guidelines development and laboratory capacity building for probiotics testing. An expert committee comprising representatives from field experts in the APEC economies, has been established to foster discussions, capacity building, and networking, enabling communication to enhance cross-border collaboration on probiotics management. This presentation will discuss the concerns in probiotics testing for quality and safety, challenges in implementing NGS for probiotics testing, method standardization, as well as the ways forward.

Deputy Executive Director, Chief Science Officer
AOAC INTERNATIONAL, Rockville, MD, USA; [email protected]
Abstract
AOAC INTERNATIONAL is currently working on several initiatives related to food safety. In addition to programs focused on foodborne pathogens and other microbial food safety issues, there are several interesting activities related to chemical food safety either in progress or under development. AOAC working groups have developed validation guidance documents for methods testing gluten and food allergens. In the case of chemical contaminants, collaborative (interlaboratory validation) studies on recently approved First Action methods for acrylamide, furan and alkyl furans, chlorate and perchlorate, and MCPD and glycidyl esters are expected to start this or next year. Furthermore, new AOAC Standard Method Performance Requirements (SMPRs) have been developed for the determination of per- and polyfluoroalkyl substances (PFAS), pyrrolizidine alkaloids, and heavy metals in various food matrices. These SMPRs should be approved within a couple of months and used as a basis for related calls for methods that are expected later this year. AOAC is also planning to re-open a call for methods for glyphosate and its metabolites. When it comes to new initiatives, AOAC INTERNATIONAL is currently initiating a new project for the development of a voluntary consensus standard for the determination of ethylene oxide residues (ethylene oxide and 2-chloroethanol) in selected food ingredients and products, which is a highly relevant topic for the SEA region. Another future AOAC initiative involves novel foods from alternative protein sources (cell-, fermentation-, insect- or plant-based alternatives), which will cover both food quality and safety analytical aspects, including considerations related to food chemical residues and contaminants.

PFAS: Development in Global Regulations, Analytical Challenges and AOAC Activities
Susan Genualdi
U.S. Food and Drug Administration
Abstract
The development of analytical methods for per- and polyfluoroalkyl substances (PFAS) in food is essential for monitoring the global food supply and for assessments of dietary exposure. In March 2022, the European Union Reference Laboratory for Halogenated Persistent Organic Pollutants in Feed and Food (EURL POPs) released a guidance document covering priority PFAS of interest, including analytical method parameters and limits of quantification (LOQs). In December 2022, the European Union published Commission Regulation 2022/2388, establishing maximum levels for perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS) in certain foodstuffs, including fish, molluscs, crustaceans, meat, poultry and eggs. The AOAC PFAS working group was established in 2023 to develop a standard method performance requirement (SMPR) for analytical methods for PFAS in food and feed. The objectives of this working group were to identify required analytes and foods for PFAS analysis, establish required limits of quantification, and define analytical method parameters. The SMPR is currently undergoing final revisions by the working group and the results will be presented. Additional system suitability requirements will be discussed which are included in the SMPR to identify analytical challenges with the analysis of PFAS in food and feed.

Risk Assessment and Development of Ethylene Oxide Risk Mitigation Guidelines for Food
Didik Joko Pursito
Head of Commercial Processed Food Production Control, The Indonesian FDA
Abstract
This presentation outlines a comprehensive risk assessment and mitigation strategy for Ethylene Oxide (EtO) and 2-Chloroethanol (2-CE) in food. Ethylene Oxide, a genotoxic carcinogenic compound, and its derivative 2-CE are of emerging concern in food safety. Risk assessment was conducted by mapping international regulations on EtO, performing processing factor analysis, and evaluating potential sources of contamination and exposure levels. As per the ALARA (As Low As Reasonably Achievable) approach, we proposed uniform maximum residue limits of 0.01 and 85 mg/kg for EtO and 2-CE, respectively.
Mitigation strategies were developed to manage the risk of EtO and 2-CE presence in food. These encompassed the application of Good Agricultural Practices (GAP), such as the use of alternative pesticides and sterilization methods, and Good Manufacturing Practices (GMP), including the minimization of food additives and raw materials that might contain EtO residues. Furthermore, stringent testing for EtO and 2-CE residues in exported and imported food products was recommended.
Furthermore, the paper addresses the lack of a uniform limit for EtO and 2-CE, highlighting the importance of establishing a uniform limit to prevent product recalls and ensure consistent food safety standards.
This study presents critical guidelines, informed by current regulations and scientific literature, for stakeholders in the food industry to minimize health risks associated with EtO and 2-CE. Future revisions can incorporate more up-to-date data to continuously improve the guidelines. This approach exemplifies proactive risk management, helping to prevent potential health crises in the food industry.
Overall, this talk provides valuable insights into the risk assessment and mitigation strategies for ethylene oxide in the Indonesian food industry. It emphasizes the importance of adopting the ALARA approach and implementing appropriate risk management actions to safeguard consumer health and ensure food safety.

Pesticides Residues in Food and Food Products: Analysis and Codex Standards for Maximum Residue Limits
Edna Callejas – Mijares, RCh., MSc.
President and CEO
JEFCOR LABORATORIES, INC., PHILIPPINES
Abstract
With globalization and increasing world population, much effort is needed to improve the global food safety supply chain and to sustainably increase agricultural production. This is in line with the second Sustainable Development Goal (SDG) of the World Health Organization (WHO) of creating a world free of hunger by 2030. Part of its targets include food security, improved nutrition, and promoting sustainable agriculture. Because of this, the cautious use of pesticides plays a huge role in agricultural productivity and crop protection to achieve food security. Pesticide residues in primary food commodities and processed food products are among the contaminants being monitored globally. High concentrations of pesticide residues pose a serious threat not only to food safety but also to consumer confidence and national reputation. This presentation will discuss briefly the importance of Codex standards and Codex guidelines in pesticide residue analysis. Establishment of Maximum Residue Limits (MRL) for pesticides is one of the requirements for authorization of a plant protection product. MRLs are very important trading standards and usually set much lower than the levels that would pose a risk to consumers. This presentation will also illustrate how Codex establish MRLs for pesticides through the rigorous process of risk assessment considering several factors, with emphasis on the residue data obtained. The analysis of pesticide residues in food and food products is very rigorous and complex task. Codex provides guidelines on Good Laboratory Practice in pesticide residue analysis (CAC/GL 40-1993) and guidelines on the Performance Criteria for Methods of Analysis for the determination of pesticide residues in food and feed (CXG 90-2017), and provide recommendations on the method of sampling as well as the portion of commodities analyzed for pesticide residue. In the Philippines, the strict implementation of the Food Safety Act of 2013 has strengthened the need for and importance of MRL establishment in food and food products. The National Codex Organization (NCO) was established through a joint executive order by the Department of Agriculture and the Department of Health to respond to the recommendations of the Codex Alimentarius Commission (CAC) of which the Philippines is a member. NCO is tasked with establishing appropriate national positions on international food safety standards in Codex, including establishing MRLs and guidelines. The Bureau of Agriculture and Fisheries Standards (BAFS) of the Department of Agriculture with the guidance of the Technical Working Group (TWG) established the Philippine National Standards (PNS) for MRL for various crops, food and food products based on Codex MRLs.

Current Approaches of Pesticide Multiresidue Analysis in Food for Regulatory Compliance
Kaushik Banerjee
ICAR-National Research Centre for Grapes, India
Abstract
Consumer acceptance of agricultural products is largely determined by their food safety credentials. The safety of food is chiefly governed by testing for a variety of pesticide residues that are controlled at their analytical LOQs or MRLs. Globally, innovative technologies for applications in promoting food safety are constantly being developed to ensure consumer safety and facilitate trade of fresh and processed commodities.
The selective and sensitive analysis of pesticide residues involves applications of advanced chromatographic and mass spectrometric techniques, e.g., GC-MS/MS and LC-MS/MS. Here, major emphasis is given to ensure the analytical method performance (accuracy, precision, sensitivity) in compliance with the national and international regulations and guidelines. In addition to large-scale multiresidue analysis based on acetonitrile or ethyl acetate extraction, it is also important to implement single residue methods for estimation of plant growth regulators, polar/ionic pesticides, etc., which require selective sample preparation workflows and specific instrumental conditions to minimize lab-to-lab variations in test results and prevent MRL non-compliances.
The objectives of this talk are to present (a) evolution of residue analytical methods in the past few decades, (b) analytical quality control guidelines to assure performance of these methods for regulatory compliance, (c) expand the scope of analysis to cover typically problematic single residue pesticides and their metabolites, and finally, (d) how implementation of good laboratory practices helps in minimizing the detection of pesticide residues in export consignments, and enhance the overall quality of fresh and processed agricultural commodities.

Determination of Multiple Human Oligosaccharides (HMOs) in Milk Formula by HPAEC-PAD (AOAC First Action Method 2022.04)
Yi Ding
Abbott Nutrition
Abstract
Human milk oligosaccharides (HMOs) are a complex category of glycans present in high abundance in human milk, with its concentration and composition closely associated with infant health. This presentation will give an overview of test method determining HMOs in Abbott nutritional products fortified with HMOs ingredients. In this method, 6 HMOs (3-FL, 2’-FL, LNnT, LNT, 6’-SL, 3’-SL) were analyzed by Ion Exchange Chromatography via high performance anion- exchange coupled with pulsed amperometric detection (HPAEC/PAD).
The HPAEC/PAD Dionex ICS5000 system was equipped with a triple pulsed electrochemical cell (ED) with a pH reference electrode (Ag/AgCl) and a gold working electrode. Chromatographic separation is achieved using a gradient of 500 mM sodium hydroxide and 300 mM sodium acetate with a PA-1 analytical column and corresponding guard column..
Ready-to-Feed products are analyzed “as-is” and powders are reconstituted to ready to feed basis prior to sampling an aliquot. An aliquot of the sample is then analyzed for the HMOs using HPAEC/PAD and quantitation was accomplished using a five level quadratic curve. As fructans (FOS, oligofructose, and inulin), sucrose, maltodextrins, and starch may interfere in the analysis of the HMOs of interest, the incorporation of fructanase and amyloglucosidase hydrolyses were inlcuded to remove these interferences.

Abstract
Human milk oligosaccharides are key compounds present in maternal milk with their concentrations and compositions reported to be closely related to multiple aspects of infant health. The incorporation of selected HMOs in infant formulas are increasing popular due to its health benefits. Quantitative analysis of HMOs is often found to be challenging due to their highly diverse composition and structural similarity. We have developed a sensitive, selective, robust, and yet fast analytical method to simultaneously separate and quantify both neutral and acidic key HMOs pairs. The HMOs studied include neutral HMO pairs (2′-FL & 3-FL and LNT & LNnT) HMO acidic pair of HMOs (3′-SL & 6′-SL). The method is then applied to understand the HMO profiles of human milk samples from Vietnam.
