Embodiment 1

[0069] The present disclosure provides a method for subcritical water extraction to assist fish scales to produce collagen peptides, including:

[0070] 1. Fish scale cleaning: Take 1kg of dried fish scales, pour it into 2% citric acid solution, 9kg of 2% citric acid solution, bubbling and cleaning at room temperature for 1 hour, and then lift it into a food-grade plastic bucket through a stainless steel filter hoist. Water once and drain to get clean fish scales;

[0071] 2. Acidification: acidify the above-mentioned clean fish scales with 10% citric acid solution 10kg, heat up to 90°C, and stir for 0.5h to obtain acidified fish scales;

[0072] 3. Subcritical extraction: put the high-temperature acidified fish scales into the autoclave through the elevator, raise the temperature to 170℃, keep the pressure in the autoclave at 1.0MPa, keep stirring for 60min, cool down to 50-60℃, and let the extract pass through the rotary table. In the material tank of the disc centrifuge, c...

Abstract

The invention provides a method for producing collagen peptide through subcritical water extraction assisted fish scales. The method comprises the steps of fish scale cleaning, acidification, subcritical extraction, directional enzymolysis, secondary flavor enzymolysis, enzyme deactivation, blending, activated carbon decoloration and deodorization, filtration and ultrafiltration, concentration, UHT sterilization, spray drying and the like. The invention also provides an application of the collagen peptide.

Description

technical field [0001] The present disclosure relates to the technical field of food value-added deep processing, in particular to a method for producing collagen peptides from fish scales assisted by subcritical water extraction and its application. Background technique [0002] my country is a big country of aquaculture and meat consumption, and has abundant aquatic resources such as fish skins and fish scales. However, these scrap resources have not been fully utilized. Among them, fish scales are raw materials with high utilization value, which have the advantages of good biocompatibility, degradability, high solubility, strong water retention, anti-oxidation, weak antigenicity, etc., and are widely used in food, medical treatment, skin care, etc. , collagen peptides in feed and other industries. [0003] However, untreated fish scales are not suitable for direct use as raw materials for collagen peptide production due to their high impurities such as ash and inorganic ...
