Abstract

The invention discloses a preparation process for a zinc fish-skin collagen polypeptide chelate to overcome the problems of difficultly controllable chelating process, a low chelating rate, low chelate yield and long chelating time in conventional preparation processes for the zinc fish-skin collagen polypeptide chelate. The process provided by the invention optimizes chelation reaction conditions, adds a NaHCO3 solution in chelating process at the same time so as to maintain stability of the pH value of a reaction system, cooperatively uses ultrasonic treatment to improve chelating efficiency and chelate yield and introduces air in chelating process air to maintain stability of chelation reaction temperature. The preparation process in the invention has the advantages of simple steps, capacity of effectively controlling the chelating process and allowing the chelating process to be more stable, short chelating time, a high chelating rate and high chelate yield.

Description

technical field

[0001] The invention relates to the technical field of deep processing of aquatic products, in particular to a preparation process of fish skin collagen polypeptide chelated zinc.

[0002] Background technique

[0003] As an essential trace element for the human body, zinc has the functions of participating in the composition of many metalloenzymes in the human body, promoting the growth and development of the body, and tissue regeneration. However, ingredients such as phosphate and oxalic acid in food will interfere with the absorption of zinc, and the absorption and utilization rate of inorganic zinc and organic zinc in zinc supplementation drugs are also low. Therefore, finding a safe and effective zinc supplement product is of great significance to human health.

[0004] In vitro, zinc is chelated with small peptides to form a trace element chelate with amino acids and small peptides as the main ligands, which can be operated in the form of a whole, wit...
