The entire food production process, from farm to table, becomes increasingly complicated year by year and its quality control is very important. Chromatography techniques are widely used in various inspection and test methods to ensure food safety.





The new food labeling system (Japan) came into effect on April 1, 2017, raising interest in the analysis of ingredients target to food labeling. We provide information on the analysis of nutrients and functional components centered on chromatography.



The new food labeling system came into effect on April 1, 2017, raising interest in the analysis of ingredients subject to food labeling. In this context, we are beginning to consider food functionality as a target for labeling based on evidence. We provide information on the analysis of functional components, centered on chromatography.


Food Additives

Food additives are those used in the production of foods, such as preservatives, sweeteners, colorants, and flavorings, or for the purpose of processing and preserving foods. The Ministry of Health, Labour and Welfare has been evaluated for the safety of food additives by the Food Safety Commission and has established specifications for ingredients and standards for their use only in cases where there is no risk of harming human health. The Food Sanitation Law establishes standards for use, manufacturing standards, and ingredient specifications.Although it is not a food additive, there is growing interest in hazardous substances contained in resin and other raw materials used in food packaging, which are used in food production, from the perspective of direct contact with processed foods.GL Sciences provide methods and product information that contribute to analytical methods related to food additives.


Heavy Metals

The demand for metal analysis is increasing in the food industry. One of these is the analysis of heavy metals in containers and packaging. The Food Sanitation Law specifies testing methods for the measurement of cadmium and lead in rubber equipment and containers and packaging. The second is the analysis of trace mineral components as dietary ingredients. Microwave decomposition equipment is convenient for analyzing trace elements in crops, where different samples can be rapidly and automatically disassembled. Conventional decomposition methods using hot plates, beakers have been developed using a simple automatic decomposition system that uses heat blocks to shorten the analysis time.



Fungal toxins exist in large numbers as natural food contaminants. Recently, aflatoxins produced by Aspergillus flavus and other chemicals have attracted particular attention in terms of food safety because they are widely known to be carcinogens to hepatocytes. As for the handling of foods containing aflatoxins, the index of aflatoxins was changed from aflatoxin B1 to total aflatoxins (total of aflatoxins B1, B2, G1, and G2: not to exceed 10 μg/kg), and it was notified on March 31, 2011. Accordingly, the Food Safety Notification No. 0816 1 provides a detailed measurement method for testing total aflatoxins.



In terms of safety checks and hazardous substance analysis, we introduce the solutions such as analysis of pesticide residues, analysis of veterinary drugs, and mycotoxin analysis. Here we introduces simultaneous testing method I (agricultural crops) using LC/MS and simultaneous testing method III (livestock and fishery products) using LC/MS for solid-phase pretreatment of pesticides and other simultaneous testing methods that have been recently revised. It also introduces convenient tools for concentrating dissolved liquids, and offers proposals for automation of solid-phase extraction. It also contains examples of chromatographic pesticide analysis.


Veterinary Drugs

Extracts of veterinary drugs are sometimes difficult to process with mini-columns due to the large number of suspended and viscous samples. Processing the sample with a cachectic mini-column not only increases the risk of operating errors, but also may deteriorate the recovery rate for unstable ingredients. InertSep provides not only fillers equivalent to the test method, but also mini-columns with improved permeability.



This solid-phase extraction product selectively collects radionuclides such as cesium and strontium.
Disk-type solid-phase extraction (Rad-disk) using molecular recognition technology can be measured directly in a radiation counter after radionuclide capture. Cartridge-type solid-phase extraction (MetaSEP AnaLig) allows selective isolation and purification of radionuclides, followed by quantification by an ICP-mass spectrometer.
