一般說明
NIST RM 8445 was prepared by representatives from the Food Allergy Research and Resource Program (FARRP), Food Products Association (FPA), Health Canada, Institute for Reference Materials and Measurements (IRMM), and U.S. Food and Drug Administration (FDA) Center for Food Safety and Applied Nutrition (CFSAN).
Total egg protein content (Nitrogen) was measured using a Leco protein analyzer (Dumas) on two sets of samples, with analysis of sets separated by several months. Results were converted to protein using a conversion factor of 6.25. The reference mass fraction value for the protein provided is associated with an uncertainty that may not include all sources of uncertainty. A unit of NIST RM 8445 consists of a single bottle containing 5 g of material.
