Scope

Scope: This standard specifies the terms and definitions of yeast hydrolysate, raw material requirements, product requirements, test methods, inspection rules, labeling, packaging, transportation, and storage. This standard applies to yeast hydrolysate derived from brewer's yeast as raw material. Main technical content: 5. Product requirements 5.1 Crushing particle size: All particles must pass through an analysis sieve with a pore size of 0.355 mm, and the sieve residue of the analysis sieve with a pore size of 0.250 mm shall not exceed 10%. 5.2 Sensory indicators: A light yellow to yellow powder with a characteristic odor of yeast hydrolysate, free from mold, spoilage, clumping, or abnormal odors or flavors, and no visible foreign matter. 5.3 Physicochemical indicators: Yeast hydrolysate products are divided into Class I, Class II, and Class III according to quality grade, and the physicochemical indicators are listed in Table 1. Table 1 Physicochemical Indicators of Yeast Hydrolysate Products Item Standard Class I Class II Class III Crude protein (%) ≥ 50.0 ≥ 45.0 ≥ 40.0 Amino acid nitrogen (%) ≥ 2.5 ≥ 2.0 ≥ 1.0 Acid-soluble protein as a proportion of crude protein (%) ≥ 80 ≥ 80 ≥ 60 Mannose (%) ≥ 5.0 Nucleotides (calculated as sodium nucleotide hydrate on a dry basis) (%) ≥ 7.0 Crude ash (%) ≤ 9.0 Water content (%) ≤ 9.0 5.4 Hygiene requirements shall comply with GB 13078. 5.5 Net content shall comply with JJF 1070. 6. Test methods 6.1 Sensory: Take an appropriate amount of sample and place it in a clean, dry white porcelain plate. Observe it under natural light and smell its odor. 6.2 Crushing particle size: Test according to the method specified in GB/T 5917.1. 6.3 Crude protein: Test according to the method specified in GB/T 6432. 6.4 Amino acid nitrogen: Test according to the method specified in Appendix C of GB/T 20886.2-2021. 6.5 Acid-soluble protein: Test according to the meth
