Food Testing

Food safety testing is a systematic quality assurance undertaking spanning the entire chain from agricultural production and processing through distribution and import/export, encompassing contaminant monitoring, food additive compliance, nutritional composition verification, mycotoxin surveillance, and detection of adulterants and illegal additives. Chinese standards including GB 2760, GB 2761, GB 2762, and the GB 5009 method series, alongside EU Regulations EC No 1333/2008 and EC No 1881/2006 and applicable FDA regulations, collectively define the primary regulatory frameworks for domestic and international food testing.

Mycotoxins represent a priority focus in food safety analysis. Aflatoxins (AFB1, AFB2, AFG1, AFG2), deoxynivalenol (DON), zearalenone (ZEN), ochratoxin A (OTA), and fumonisins (FB1/FB2) are widespread in grains, nuts, and spices, with LC-MS/MS quantification placing high demands on standard stability and assigned-value accuracy. Additional testing areas requiring dedicated reference standards include food additive compliance (preservatives, sweeteners, colorants, antioxidants), nutritional labeling verification for vitamins and amino acids, food contact material migrant testing, and screening for illegal adulterants such as melamine and Sudan dyes.

CATO Research Chemicals Inc. offers over 2,950 food safety testing reference standards covering the major testing categories and priority regulated substances under Chinese and international frameworks, each supplied with full COA incorporating HPLC and LC-MS assigned values. Isotope-labeled internal standards are available for key analytes, with custom mixed standard solutions for mycotoxins, food additives, and other target groups available on request. The majority are in stock for rapid laboratory procurement.
