This Standard Reference Material (SRM®) is intended primarily for use in validating methods for determining proximates, fatty acids, calories, vitamins, elements, amino acids, aflatoxins, and acrylamide in peanut butter and similar matrices. This SRM® can also be used for quality assurance when assigning values to in-house control materials. A unit of NIST-2387 consists of three jars of peanut butter containing 170 g each. Reference values for proximates, caloric content, fatty acids, amino acids, water-soluble vitamins, aflatoxins and acrylamide. /// Sample values - please ask for current certificate.
