Food Ingredient Reference Materials

FCC Reference Standards banner

To equip industry with all of the tools necessary to perform analytical procedures with a high degree of accuracy, FCC monographs and methods are often developed with reliance on authenticated Reference Standards, which may be purchased through USP. When a shipper or receiver is confronted with passing judgment on the suitability (i.e., identity and purity) of a food ingredient, use of an authenticated Reference Standard allows for a rapid and unbiased decision to satisfy quality assurance, contractual agreements, and regulators. All items sold as USP Reference Standards have passed a rigorous testing protocol designed to ensure the suitability of the material for the test methods provided in the FCC and other USP publications.


USP offers thousands of reference standards, including food ingredient standards for flavorings, preservatives, nutrients, and melting point standards, among others.

Increase food ingredients safety
Stringent monograph identity criteria, together with a real-life sample of the food ingredient, allow food manufacturers to identify potential adulteration.

Protect food ingredients identity
Food-ingredient producers that sponsor the development of a monograph and reference materials will enjoy additional protection of the authenticity of their product by always having an authentic sample publicly available. This authentic sample will allow any prospective or current customer to evaluate any other material for purity and authenticity, and thus increase the trust and safety in a food ingredient that is supported in such a transparent way.

Enhance analytical test results reliability
Test laboratories frequently use reference standards to calibrate analytical methods or as quality control samples—increasing test results confidence.
