Problems solved by technology

In daily life, because animal tissues containing collagen are often combined with a large amount of fat (such as skin) or inorganic minerals (such as bone), due to reasons such as poor taste, inconvenient eating and difficult digestion, people often eat less
On the one hand, the necessary nutrition for the human body cannot be supplemented, and at the same time, it causes a huge waste of resources

Embodiment 1

[0028] The preparation of embodiment 1 collagen powder

[0029] (1) Take 10kg of dehaired pigskin, wash it with tap water, and scrape off the accompanying fat;

[0030] (2) Cut the fat-removed pork skin in (1) into thin strips, and use a chopping machine to cut them into pieces smaller than 0.5cm 3 small pieces;

[0031] (3) After chopping and mixing the pigskin material, soak it in 10% sodium carbonate solution for 4 hours at 50° C., wash it, and basically remove the fat;

[0032] (4) After soaking the pigskin material processed in step (3) with 0.1M dilute hydrochloric acid for 5 hours, beating with a colloid mill;

[0033] (5) Adjust the pH value of the pigskin material after beating to 3.5 with hydrochloric acid, add 50 g of pepsin, and stir for 24 hours;

[0034] (6) Centrifuge after the reaction, and the separated precipitate will continue to be added to the next batch of materials for beating. The supernatant liquid is neutralized with sodium carbonate and then direc...

Embodiment 2

[0036] Adopt 0.5M acetic acid to soak 4 hours in the step (4), all the other are with embodiment 1.

Embodiment 3

[0038] (1) Take the collagen powder prepared in Example 1, mix soybean oligosaccharides and soybean isoflavones in a mass ratio of 20:5:1, mix well, and sterilize by ultraviolet irradiation;

[0039] (2) Filling prepared materials into capsules, that is, processing into collagen beauty and health food.

Abstract

The present invention discloses a collagen protein powder, its preparation method and application. Its preparation method includes: using pork skin as raw material, defatting, cutting, hashing, soaking in alkaline solution, washing with water, soaking in acid solution, pulping, using proteinase to make hydrolysis, neutralizing separated supernatant fluid to neutrality, spray-drying to obtain the product collagen protein pwoder which has good solubility, has no bad smell and can be used for preparing health-care food, food additive, active component of cosmetics or medicine excipient.

Description

technical field [0001] The invention belongs to the field of collagen protein and its preparation or processing, and more specifically relates to a collagen protein powder and its preparation method and application. Background technique [0002] Collagen is a non-nutritive hard protein that is widely found in connective tissues such as skin, bones and tendons of vertebrates. Collagen contains a large amount of glycine, alanine, proline, hydroxyproline, and hydroxylysine, among which hydroxyproline and hydroxylysine only exist in collagen, accounting for about 14%. Therefore, the hydroxyproline and hydroxylysine needed by the human body to synthesize collagen can only be taken from animal foods, the most common being animal skins, especially pig skins. Traditional Chinese medicine in my country has a saying that "replenish blood with blood and nourish skin with skin". Regular consumption of foods rich in collagen can meet the normal metabolism requirements of collagen in the...
