food integrity (11)

Jill Hoffman, McCormick &Co, gave the keynote address at the APAC (Asia- Pacific) Food Safety Conference 2019 in Sydney. She outlined the breadth of work carried out by food safety and quality professionals. However, when considering the emerging risks companies are facing, then food authenticity, fraud and sustainability should also be included in the increasing number of risks companies have to take into account. Therefore, these need to be dealt with by building a food integrity culture.

3435350351?profile=RESIZE_710xThe EU FoodIntegrity project has published a number of Scientific Opinions on difficult stakeholder derived issues that concern food fraud. The topics were all identified by stakeholders and are intended as documents that describe best practices. The published Scientific Opinions can be found here under the 'Scientific Opinions' tab.

The latest Scientific Opinion published is on "Use of NMR applications to tackle future food fraud issues". The SO discusses how both targeted (allows the identification of specific markers of identity/adulteration for a given foodstuff) and untargeted (the chemical profile of the whole foodstuff is used to create a unique fingerprint as a reference for suspect samples) NMR methodologies are applied in routine use for food fraud monitoring. The cost-effective approaches for routine application are discussed using examples of Food Screener™ and benchtop low-field instruments.

The Codex Committee on Methods of Analysis and Sampling (CCMAS) held its 40th Session in Budapest, Hungary, from 27 to 31 May 2019. The Session was attended by 49 Member countries and 1 Member organization and 12 observer organisations.

Selvarani Elahi, representing the UK Government Chemist, attended as part of the UK delegation together with colleagues from the Food Standards Agency and the Association of Public Analysts.

CCMAS considers methods of analysis for Codex standards and testing in relation to international food trade. CCMAS 40 discussed analytical methods for nutritional metals, acid value and free fatty acids in palm oil, milk and milk product commodities, 'gluten free' labelling in products containing cereals, pulses and legumes, and herbs & species. The meeting also received updates from working groups on the revision of three substantive Codex documents: general standard for methods of analysis and sampling, guidelines on measurement uncertainty and guidelines on sampling. Work on these documents continues in order to reach global consensus.

As there is increasing interest in food integrity and food authenticity at Codex, the poster on the Food Authenticity Network attracted attention from delegates. Follow-up discussions are planned with member countries on creating ‘country-specific’ pages on the Food Authenticity Network for their countries in order to create a truly global network. Discussions will also continue with the food industry and observer organisations looking to support the work of the Network.

If you would like further information on supporting the Network, please contact us on Secretary@foodauthenticity.uk.

The Food Authenticity Network is mentioned in the meeting report, which is available from the Codex Alimentarius website.

Spanish authors have published a chapter in a new book - "Mass Spectrometry - Future Perceptions and Applications", reviewing the use of LC-MS (Liquid Chromatography- Mass Spectrometry) in a wide number of authenticity applications. The chapter discusses the use in targeted analysis with or without chemometrics for identifying polyphenols to authenticate different fruits, vegetables and honey. It also reviews the use of LC-HRMS (High Resolution Mass Spectrometry) with chemometrics in targeted applications identifying biomarkers in saffron, fruits, cocoa beans, spices and rice. Non-targeted LC-MS applications for metabolomics in a wide range of foods are also covered.

Food fraud a worldwide problem and many countries continue to commit considerable resource to combat the issue. With the food supply chain now truly global, there is acknowledgement that having agreed definitions for terms commonly associated with food authenticity and food fraud would be of great benefit.

The Norwegian Institute of Food, Fisheries and Aquaculture Research (Nofima), has led a European initiative with the objective of making communication regarding food fraud more precise. Together with food fraud experts (including from the Food Authenticity Network Team) from several European countries including the UK, a European standard has been created that defines many of the English terms and concepts used in connection with food fraud. The words are placed in a hierarchical system that makes it easier to understand how they relate to each other - see image.

The standardisation was coordinated as part of the EU-funded Authent-Net and FoodIntegrity projects. It was published in January 2019 by Standard Norway, and it is also being distributed by several other National Standardisation Bodies in Europe; currently Estonia, Netherlands, and the UK.

This standard represents an important first step in the global standardisation of these terms which will help facilitate trade, combat food fraud and better secure our food supply chains.

IFST has re-written its “Food authenticity testing” Information Statement and split it into two parts:

Food authenticity testing part 1: The role of analysis, which now covers the role of analytical testing within the context of an overall supply chain assurance strategy.

Analytical testing is a valuable tool in the armoury to assure food authenticity but cannot be used to identify every type of food fraud.  It is only one part of an overall strategy to mitigate fraud risk.

Many modern tests are based upon comparing a pattern of measured values in the test sample with patterns from a database of authentic samples. Interpretation is highly dependent on the robustness of the database, and whether it includes all possible authentic variables and sample types. This information may not be released by the laboratory.  Interpretation of results is rarely clear-cut, and analytical results are often used to inform and target further investigation (such as unannounced audits or mass-balance checks) rather than for making a compliance decision.

This paper describes where testing can and cannot be used, and highlights generic issues relating to interpreting food authenticity testing results.

Food authenticity testing part 2: Analytical techniques, which gives describes specific analytical techniques, their applications, strengths and weaknesses.

This paper describes the principles, different configurations, applications, strengths and limitations of some of the more common analytical techniques used in food authenticity testing:
• Mass spectrometry
• Stable isotope mass spectrometry
• DNA analysis
• Nuclear magnetic resonance spectrometry
• Spectroscopy.

Generic strengths and limitations of food authenticity test methods, particularly those relating to methods comparing against reference databases of authentic samples, are discussed in “Food authenticity testing: The role of analysis”. It also describes the difference between targeted and untargeted analysis.

Ensuring Food Supply Chain Integrity

This review paper gives the some of the outcomes of two EU FP7 Projects - EDEN and SNIFFER on the development of food defence analyses in the food chain. Food defence guidelines have been developed based on a parallel system to food safety HACCP analysis which include systems such as vulnerability analysis and critical control points (VACCP), and threat assessment critical control points (TACCP). Once mapping of the gaps and needs had been carried out, a secondary aim of the food defence work in the EDEN project was to test new technologies both targeted and untargeted that could be used for food defence purposes. The SNIFFER project (Sensory devices network for food supply chain security) addressed problems related to the detection of biological and chemical agents in the food supply chain, by looking at commercially available sensors in a sensor network that could be deployed at vulnerable points in the food supply chain. 

Food defence practices can help prevent deliberate contamination, be it motivated by economic, revenge or ideological reasons. Food defence should therefore be an integral part of food supply chain integrity and not just an afterthought in the wake of an incident. The detection tools investigated by EDEN and SNIFFER have potential, but a wider range of contaminants and food matrices needs to be investigated before these tools could be broadly adopted.
