Benefits of technology

This invention relates to an improved method for producing bioactive substances with better quality and higher activity than traditional methods used today. It involves lower costs while still maintaining its desired properties such as being highly pure or having excellent crystallinity. Additionally it can improve how well people are able to fight off diseases by giving them more effective medication that helps their bodies recover faster from harmful conditions caused during times they have been exposed to these treatments.

Problems solved by technology

Technologies aim at finding ways to increase the use of coppers from animal feeds or food products without causing harmful effects such as negative side effects like increased nitrogen consumption. Current methods involve adding these metals through various routes, including ingestion via water intake, injection into muscles, gut flushing, etc., leading to accumulation issues around them. To address this issue, searching for novel compounds containing specific cystine moieties called tetrapods can be used instead of traditional chemical agents.

Embodiment 1

[0021] A preparation method for feed additive nano small peptide chelated copper, comprising the steps of:

[0022] (1) Preparation of buffer solution: Prepare 0.2M disodium hydrogen phosphate solution and 0.1M citric acid solution for later use;

[0023] (2) Preparation of dry peptide powder: Take 1.6 kg of soybean meal powder (particle size ≤0.6 mm) and dissolve it in 10 L, pH=4.3, 0.2M disodium hydrogen phosphate solution and 0.1M citric acid solution in a buffer solution, at 40°C Stirring at low temperature for 12 min; heat treatment at 90°C for 17.5 min; then adding alkaline protease and flavor protease [Alcalase alkaline protease (liquid) 2.4 L, Flavorzyme flavor protease 500 MG, both provided by Novozymes Investment Co., Ltd., two The mass ratio of the two enzymes is 1:1], at 55°C, pH 7.0 (adjust the pH with 0.2M disodium hydrogen phosphate solution), and the enzyme concentration is 10.5% (that is, the two enzymes account for 10.5% of the mass of soybean meal powder). ...
