Embodiment 1

[0016] A low-value fish bone polypeptide chelated calcium is prepared from low-value fish bones through crude fish bone meal, fermentation of fish bone meal, step-by-step enzymatic hydrolysis, isoelectric point precipitation, chelation and freeze-drying. The fermentation steps of fish bone meal are as follows: mix fish bone meal with pure water, glucose and potato extract to prepare lactic acid bacteria fermentation medium, sterilize at high temperature, inoculate lactic acid bacteria after cooling, ferment at 28~32°C for 3~7 days, concentrate, dry and grind to obtain Fermented Fish Bone Meal. The mass ratio of fish bone meal to pure water, glucose and potato extract is 14~25:60~75:2~4:3~6; the lactic acid bacteria is Lactobacillus plantarum. During the fermentation process, organic acids such as lactic acid, acetic acid, pyruvic acid, succinic acid, and fumaric acid and metabolites such as free amino acids, polysaccharides, and enzymes are produced, and the calcium in the fis...

Embodiment 2

[0023] A low-value fish bone polypeptide chelated calcium is prepared from low-value fish bones through crude fish bone meal, fermentation of fish bone meal, step-by-step enzymatic hydrolysis, isoelectric point precipitation, chelation and freeze-drying.

[0024] A most preferred preparation method of fish bone meal and protein peptide mixture chewable tablet, comprises the following steps:

[0025] 1) Crude fish bone powder: add 34wt% sodium carbonate solution to the ground fish bone, soak for 32min, the volume ratio of fish bone and sodium carbonate solution is 1:3.6, filter, wash the precipitate with pure water, and then send it into a pressure vessel , control the pressure to 0.15MPa, cook for 5min, dry and pulverize to obtain fishbone meal;

[0026] 2) Fermentation of fish bone meal: Mix fish bone meal with pure water, glucose and potato extract to prepare lactic acid bacteria fermentation medium, sterilize at high temperature, inoculate lactic acid bacteria after cooling, ...

Embodiment 3

[0032] A low-value fish bone polypeptide chelated calcium is prepared from low-value fish bones through crude fish bone meal, fermentation of fish bone meal, step-by-step enzymatic hydrolysis, isoelectric point precipitation, chelation and freeze-drying.

[0033] A preparation method of low-value fishbone polypeptide chelated calcium, comprising the following steps:

[0034] 1) Coarse fish bone powder: add 30wt% sodium carbonate solution to the ground fish bone, soak for 30 minutes, the volume ratio of fish bone and sodium carbonate solution is 1:3.5, filter, wash the precipitate with pure water, and then send it into a pressure vessel , control the pressure to 0.13MPa, cook for 3min, dry and pulverize to obtain fishbone meal;

[0035] 2) Fish bone meal fermentation: Fish bone meal was mixed with pure water, glucose and potato extract to prepare lactic acid bacteria fermentation medium, sterilized at high temperature, cooled and inoculated with lactic acid bacteria, fermented ...

Abstract

The present invention discloses a low value fish bone polypeptide chelated calcium. The low value fish bone polypeptide chelated calcium is prepared from low value fish bones and prepared by fish bone meal coarse preparing, fish bone meal fermenting, stepwise enzymolyzing, isoelectric point precipitating, chelating and freeze-drying. Beneficial effects are as follows: small molecule bone polypeptides are prepared by using a synergetic enzymatic hydrolysis of marine protease and terrestrial protease. The prepared bone polypeptides are small in molecular weight, chelated with calcium ions to obtain the bone polypeptide chelated calcium, and high in an absorption rate in human body, and do not produce blood calcium symptoms. The human body is good in an absorption effect for calcium in the bone polypeptide chelated calcium. After a long term consumption, a calcium apparent absorption rate, a calcium retention rate, a bone density, a bone mineral salt content, a bone cortex area, a bone energy absorption, etc. all show an obvious increasing trend.

Description

technical field [0001] The invention relates to the field of preparation of health products, in particular to a low-value fishbone polypeptide chelated calcium. Background technique [0002] my country is a big country in aquatic products production, and the output of freshwater fish and sea fish in my country shows a steady upward trend every year. In recent years, my country's fish processing industry has developed rapidly, and now it has formed products such as frozen products, salted fish products, fish meal for feeding, surimi and their products. Surimi products are favored by consumers because of their high protein, low fat, variety, and storage resistance. They have become the main means of fish processing, but their meat harvesting rate is generally only 25-30%. The remaining fish body is rich in minerals such as calcium and phosphorus, and is a good natural source of calcium. [0003] Due to the low content of naturally occurring marine active peptides in organism...
