Problems solved by technology

[0002] In the production process of traditional collagen powder, its concentration and sterilization steps adopt the method of heating and heating. However, this method will greatly increase the probability of denaturation of the concentrated collagen, which will directly lead to the loss of collagen produced by the traditional process. Yellowish, strong fishy smell
In addition, the traditional heat sterilization method cannot effectively remove thermophilic bacteria
Furthermore, traditional collagen uses freshwater fish or farmed fish or pigs, cattle and sheep as raw materials. Nowadays, freshwater fish is increasingly polluted by human activities, such as environmental pollution, hormone pollution, antibiotic residues, feed hormones, and pesticide residues. etc., which may produce pollution and hidden dangers of disease in the growth environment and breeding process, which will lead to the pollution of the produced collagen powder

Embodiment 1

[0022] The method for extracting collagen powder from deep-sea cod fish skin comprises the following steps:

[0023] Step 1. Take fresh deep-sea cod skin and wash it several times with tap water to remove some impurities and grease;

[0024] Step 2, cook and remove oil at 70°C, dissolve the collagen in the cod skin, and remove the fish oil with an oil-water separator;

[0025] Step 3, utilizing papain, bromelain and subtilisin to degrade the collagen dissolved in step 2 into small molecule collagen polypeptides;

[0026] Step 4, the small molecule collagen polypeptide in step 3 is deodorized and decolorized by log activated carbon;

[0027] Step 5. Perform plate and frame filtration on the deodorized and decolorized small-molecule collagen polypeptide, that is, use biofilm filtration to remove activated carbon, and separate the decolorized collagen polypeptide liquid;

[0028] Step 6, concentrating the small molecule collagen polypeptide liquid in step 5, and concentrating t...

Abstract

The invention provides a method for extracting collagen powder from deep sea cod skin, and the method comprises the following steps: washing fresh cod skins with tap water for multitime; boiling at low temperature, removing oil; carrying out a biological enzymatic hydrolysis; removing fishy with log active carbon and decolouring; carrying out a plate filtration; condensing; disinfecting physically; sieving; granulating with spray at low temperature; collecting a collagen powder finished product. The method for extracting collagen powder from deep sea cod skin employs deep sea cod fishes, thereby guarantying security and nature of source, decreasing probability of pollution of collagen finished product. In addition, the whole process from biological enzymatic hydrolysis to spray drying employs low temperature control (the temperature is controlled under 50 DEG C), thereby guarantying non-yellow collagen powder color, non-fishy smell, unchanged spatial tissue structure of protein, non-degeneration of collagen and high activity of protein.
