Problems solved by technology

However, in the existing process of extracting bone collagen, a large amount of acid and / or alkali and long-term enzyme preparation are used to treat raw materials, the polypeptide chain of collagen is excessively hydrolyzed, resulting in denaturation of collagen, and the main component of the obtained product is amino acid and polypeptides, and this process only retains part of the active ingredients in the sturgeon cartilage, wasting other active ingredients, and the yield of active substances is not high

Embodiment 1

[0027] This example provides a process for extracting non-denatured type II collagen from sturgeon cartilage, which is prepared by degreasing, cooking, freezing, drying and grinding the cartilage in the head and / or bone of sturgeon .

[0028] Before degreasing, the head and / or bones of the sturgeon are sorted to remove the cartilage.

[0029] Among them, degreasing refers to putting the selected cartilage into a NaOH solution with a mass fraction of 4% and a temperature of 47°C for cleaning and degreasing, so as to remove adhesions on the surface of the cartilage such as fish meat, fish skin, blood vessels, mucous membranes, and nerves. Tissues and fish scales are then rinsed with solution pH to neutral on the cartilage surface. Specifically, the mass of NaOH solution is 5-10 times that of cartilage.

[0030] Among them, cooking refers to sending the cleaned cartilage into a continuous steam heating device, and the temperature of the heating zone rises from 80°C to 142°C. P...

Embodiment 2

[0035] This example provides a process for extracting non-denatured type II collagen from sturgeon cartilage, which is prepared by degreasing, cooking, freezing, drying and grinding the cartilage in the head and / or bone of sturgeon .

[0036] Before degreasing, the head and / or bones of the sturgeon are sorted to remove the cartilage.

[0037] Among them, degreasing refers to putting the selected cartilage into a NaOH solution with a mass fraction of 5% and a temperature of 50°C for cleaning and degreasing to remove adhesions on the surface of the cartilage such as fish meat, fish skin, blood vessels, mucous membranes, and nerves. Tissues and fish scales are then rinsed with solution pH to neutral on the cartilage surface.

[0038] Among them, cooking refers to sending the cleaned cartilage into a continuous steam heating device, and the temperature of the heating zone rises from 78°C to 140°C. Preferably, the cooking is carried out in a continuous steam heating tunnel, and t...

Embodiment 3

[0043] This example provides a process for extracting non-denatured type II collagen from sturgeon cartilage, which is prepared by degreasing, cooking, freezing, drying and grinding the cartilage in the head and / or bone of sturgeon .

[0044] Before degreasing, the head and / or bones of the sturgeon are sorted to remove the cartilage.

[0045] Among them, degreasing refers to putting the selected cartilage into a NaOH solution with a mass fraction of 3% and a temperature of 45°C for cleaning and degreasing, so as to remove adhesions on the surface of the cartilage such as fish meat, fish skin, blood vessels, and mucous membranes. , nerve tissue and fish scales, and then wash the cartilage surface to a neutral pH solution.

[0046] Among them, cooking refers to sending the cleaned cartilage into a continuous steam heating device, and the temperature of the heating zone rises from 82°C to 144°C. Preferably, cooking is carried out in a continuous steam heating tunnel, and the ca...

Abstract

The invention discloses a process for extracting non-denatured II-type collagen from sturgeon cartilage. The process comprises the following steps: cleaning cartilage in sturgeon head and / or fishbonein a NaOH solution to remove adhesive substances on the surface of the cartilage, performing flushing to neutrality, then sending the cartilage after flushing into continuous heating equipment for cooking, performing freezing, then sending the cartilage after freezing into continuous drying equipment for drying, and performing grinding into a powder to obtain a compound containing the non-denatured II-type collagen. According to the preparation process, the non-denatured II-type collagen can be obtained, chondroitin sulfate and hyaluronic acid in the cartilage can be reserved, and the extraction technological process is simple. Compared with the prior art, the process shortens production period, has low input, has high yield, and can achieve large-scale production.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a process for extracting non-denatured type II collagen from sturgeon cartilage. Background technique [0002] Sturgeon is one of the earliest vertebrates in existence. Because of its strong ability to accept artificial feed, it has excellent breeding traits such as easy domestication, fast growth, large body, good meat quality, and good nutritional content. It is an economic fish widely farmed in the country. Sturgeon cartilage is rich in collagen, calcium, iron, zinc, selenium, magnesium and other trace elements, as well as chondroitin sulfate and hyaluronic acid. It is a very good nutritional supplement for repairing articular cartilage. However, in the existing process of extracting bone collagen, a large amount of acid and / or alkali and long-term enzyme preparation are used to treat raw materials, the polypeptide chain of collagen is excessively hydrolyzed, resultin...
