T/BYXT 107-2024 Feed-grade Natural Skepalite Powder

Scope

Scope: This document specifies the terminology definitions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and sales and service requirements for natural clinoptilolite powder. This document applies to feed-grade clinoptilolite powder prepared from natural clinoptilolite as raw material; Main technical content: I. Physicochemical indicators shall comply with the requirements of Table 1. Table 1 Item Indicator Superior Grade First Grade Ammonia absorption value a/(mmol/100 g) ≥ 100.0 ≥ 90.0 Particle size b /% 95 90 Dry loss (mass fraction) /% 6.0 10.0 Moisture /% ≤ 10 12 a The content of clinoptilolite in the product is linearly related to the ammonia absorption amount. According to industry practice, the clinoptilolite content in the product is determined by measuring the ammonia absorption amount. b The particle size is calculated by passing through a 0.9 mm sieve. II. Requirements for detoxification performance shall comply with the provisions of Table 2. Table 2 Item Requirements Superior Grade First Grade Gastric pH 3.0 condition Intestinal pH 6.5 condition Gastric pH 3.0 condition Intestinal pH 6.5 condition Aflatoxin B1 /% ≥ 99 85 90 Ochratoxin A /% ≥ 99 80 70 Vomitoxin /% ≥ 99 80 70 Note: The in vitro adsorption rate of aflatoxin B1 under gastric (pH 3.0) and intestinal (pH 6.5) pH conditions was 100% and 90% respectively. The in vitro adsorption rate of ochratoxin A under gastric (pH 3.0) and intestinal (pH 6.5) pH conditions was 100% and 87% respectively. The in vitro adsorption rate of vomitoxin under gastric (pH 3.0) and intestinal (pH 6.5) pH conditions was 100% and 85% respectively.
