Embodiment

[0015] 1) Preparation of fish scale powder: Soak the fish scales in clear water for 2 days, then add sodium bicarbonate with a mass volume ratio of 1% in the soaked clear water to soak and degrease (that is, the mass volume ratio: the number of grams of solute per 100ml), and then rinse , dried to constant weight, finally crushed to 80 mesh, set aside. Among them, the fish scales can be the leftovers from the processing of tilapia, large yellow croaker and red sea bream.

[0016] 2) Activation of strains:

[0017] ① Skimmed milk activation medium: Boil the fresh milk and put it into a triangular beaker, let it stand at 100°C for 30 minutes, then cool it down naturally. / 3 places, packed well, sterilized by batch sterilization method, cooled, stored at low temperature, and set aside. The batch sterilization method is sterilizing at 106°C for 30 minutes, once a day for 3 consecutive days.

[0018] ② Inoculate Nisin butanedione, Lactobacillus bulgaricus and Streptococcus therm...

Abstract

The invention relates to the biotechnology, and in particular to scale collagen polypeptide being fermented by lactobacillus and a preparation method thereof. The lactobacillus is used for fermenting scales, so the scale collagen polypeptide can be obtained. The main product is polypeptide with the molecular weight distribution range of 1000 Daltons to 3000 Daltons, the digestion absorption rate can reach 100 percent, and the nutrition and physical function can be remarkably improved. The main nutrient substances produced by the scale powder which is fermented by the lactobacillus are osteocalcin and collagen polypeptide, the efective microbial flora in ineestinal is utilized for fermenting the natural scale powder which is rich in collagen polypeptide and has an appropriate calcium-phosphorus ratio, the acid product produced during the fermentation process of the lactobacillus can convert partial insoluble calcium (hydroxylapatite) in the scales to soluble calcium (calcium lactate and compound amino acid calcium), and moreover, extracellular proteinase can hydrolyze the scale protein so as to provide the collagen polypeptide, amino acid and phosphorus which can assist the absorption of the calcium.

Description

technical field [0001] The invention relates to biotechnology, in particular to a fish scale collagen polypeptide fermented by lactic acid bacteria and a preparation method thereof. Background technique [0002] In recent years, with the adjustment of the aquatic industry structure, my country's aquatic product processing industry has also gradually developed and grown. A large amount of leftovers are produced while processing fish products, accounting for 30% to 50% of the total mass of processed fish, of which about 5% are fish scales. Restricted by technology and traditional concepts, fish scales have not been fully utilized for a long period of time, but have been thrown away as garbage. It is estimated that 300,000 tons of fish scales are discarded in my country every year. [0003] Fish scales contain a variety of nutrients needed by the human body. In addition to a large amount of calcium, they also contain phospholipids, phosphoproteins and other substances require...
