APP is the acronym for “Alternate Protein Product.” The term "Alternate Protein Product" is the name used by FNS to identify products meeting requirements set forth in Appendix A of the NSLP, SBP, SFSP, and the CACFP within the section entitled Alternate Protein Products.
An APP is required
- to be processed so that some portion of the non-protein constituents of the food is removed,
- to have a biological quality at least 80% that of casein using the PDCAAS method, and
- to contain at least 18% protein by weight when fully hydrated or formulated.
These requirements are found in Appendix A to 7 CFR 210, 220, 225, and 226. Some examples of APPs include soy flours, soy concentrates, soy isolates, whey protein concentrate, whey protein isolate and casein. Processed food items, such as a vegetarian burger or patty, may contain APPs but the entire item cannot be considered an APP as the food item contains other ingredients such as seasonings or breading.
