Testing for residual agricultural chemicals and veterinary drugs
The NISSIN Global Food Safety Institute prevents the contamination of products by harmful substances by conducting inspections for any residual agricultural chemicals and veterinary drugs that may be contained in raw materials. NASRAD-700 (Nissin's Analytical System for Residual Agricultural Chemicals and Veterinary Drugs), the latest version of an independently developed analysis system, can rapidly perform simultaneous analysis of 545 residual agricultural chemicals and 188 veterinary drugs. In addition, the use of FASRAC (Food Automatic Analytical Systems for Residual Agricultural Chemicals), an automatic pre processing apparatus, has dramatically improved testing proficiency and accuracy.
Food allergen testing
In addition to employing official testing methods for seven specified allergenic raw materials for which labeling is required, the institute conducts tests for 16 additional similar materials for which labeling is recommended using an independently developed testing method based on genetic information.
Testing for carcinogens
The institute is independently developing new analysis systems that test for carcinogens in food products. NESMAGET (Nissin's Evaluation Systems for Mammalian Geno Toxicity), a test method for human cell mutagenicity, applies the expression mechanism of the DNA repair gene p53R2, which the institute developed in 2003. In addition, in 2008 the institute discovered a gene cluster that exhibits a characteristic fluctuation in a carcinogenesis promoter. Using the level of expression of this gene cluster as an index, the institute developed NESTUP (Nissin's Evaluation System for Tumor-promoting Activity), a method that enables fast, simple, low-cost testing for carcinogenesis promoters.
Testing for food poisoning bacteria groups
The institute tests for food poising bacteria using three test methods, allof which can rapidly test for bacterial groups based on genetic information:the specific bacterial group rapid batch test method, the acetic acid tolerantlactic acid bacterial test method, and the emetic bacillus cereus test method.
Testing system for radioactive substances
The institute has introduced high-precision gamma ray spectrometers based on germanium semiconductor detectors, which make possible analysis that discriminates between the radio nuclides cesium 134 and 137, for use in periodic testing of water (tap water and ground water) and products at the NISSIN FOODS Group's production plants and affiliated plants. This testing is in compliance with tightened new national standards for radioactive substances enacted in April 2012.
Simultaneous heavy metals analysis
Heavy metal pollution of waterways and soil caused by insufficiently treated effluent, a problem associated with the rapid industrialization of emerging nations, is a concern. Accordingly, the institute performs simultaneous analysis of heavy metals using inductively coupled plasma emission analysis(ICP-AEA) and inductively coupled plasma emission mass spectrometry (ICP-MS).
Irradiation of foods for the purpose of sterilization is not permitted in Japan. (However, irradiation of potatoes to prevent sprouting is allowed.) For this reason, the institute performs testing to detect irradiation using photo stimulated luminescence (PSL) and thermoluminescence (TL).
