Scope

Main Technical Content: Processing Technology Specification for Enzymatic Decomposed Feather Powder as Feed Raw Material 1 Scope This document specifies the basic conditions, raw materials, processing techniques, and production record requirements for the enzymatic decomposition of feathers into feed raw materials. This document applies to the production process of enzymatically decomposed feather powder, which is made from poultry feathers as raw materials through pretreatment, steaming, enzymatic decomposition, filtration, concentration, spray drying, and packaging. 2 Normative Reference Documents The content of the following documents is an essential part of this document through normative reference. Among them, the dated reference documents only apply to the corresponding version on that date; the undated reference documents apply to the latest version (including all amendment sheets) of this document. - GB 5749: Sanitary Standards for Drinking Water - GB 10648: Feed Labeling - GB/T 23527: Protease Preparations - NY/T 915-2017: Enzymatically Decomposed Feather Powder as Feed Raw Material 3 Terms and Definitions The following terms and definitions apply to this document. 3.1 Pretreatment The process of removing impurities (stones, feces) from raw materials. 3.2 Enzymatic Decomposition The process of enzymatically decomposing raw materials into simple molecules at a temperature of 50℃~60℃ and a pH value of 9~10. 3.3 Filtration Separating solid-liquid mixtures through porous media. 4 Raw Material Requirements 4.1 Raw Material Acceptance The purchased raw materials should be fresh and free from contamination. Poultry feathers with disease or spoilage should not be used. 4.2 Raw Material Storage Feathers with a water content of less than 25% should be stored at room temperature, and feathers with a water content of more than 25% should be stored at 0℃~10℃. 4.3 Processing Water It should comply with the requir
