Abstract
The invention discloses a method for extracting taurine from oysters. The method comprises steps of removing shells of the oysters, smashing, putting into a vessel, adding water 6 times mass of the oysters, heating up to 80 DEG C in a water bath, and hydrolyzing for 2 hours; filtering, adding water 4 times mass of the filter residue, continuing heating up to 80 DEG C in a water bath, and hydrolyzing for 2 hours; filtering, combining two filtrates, regulating pH value to be 2-3 through hydrochloric acid, filtering, carrying out evaporation and concentration crystallizing on the filtrate so as to obtain crude taurine, and washing the crude taurine 2-4 times through 95% ethyl alcohol so as to obtain refined taurine. The method for extracting taurine from oysters offers a new way for producing taurine.
Description
Technical field
The present invention relates to a kind of extracting method of marine bioactivity material, be specifically related to a kind of method of extracting taurine from oyster.
Background technology
Taurine has the multiple important physiological actions such as metabolism that promote brain development, vision enhancing, adjusting nerve conduction, promotion absorption, digestion fat, participate in bile salt, and heart, liver, endocrine dysfunction are also had to physiological function.Along with people are to the deepening continuously of taurine physiological action research, the application of taurine is also more and more extensive.As nutrition-fortifying agent, taurine is widely used in food (as milk, milk powder, beverage) and dietary supplements.Meanwhile, in various sea-foods and pluck, there is a large amount of taurines, particularly utilize low value sea-food to extract taurine, and the tankage after extracting are processed into fodder additives, make low value sea-food realize increment, increase income.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, and a kind of method of extracting taurine from oyster is provided.
Technical problem to be solved by this invention is to realize by following technical scheme.A kind of method of extracting taurine from oyster of the present invention, is characterized in: oyster is shelled, pulverize, put into container and add the water of 6 times of quality, heating in water bath to 80 ℃, is hydrolyzed 2 hours.Filter, filter residue is added to the water of 4 times of quality, continue heating in water bath to 80 ℃, be hydrolyzed 2 hours.Filter, merge filtrate twice, with hydrochloric acid, adjust pH value to 2-3, filter, by filtrate evaporation concentration, crystallization, be taurine crude product, taurine crude product is to taurine fine work for 2-4 time by 95% washing with alcohol.
Compared with prior art, the present invention developed utilize oyster extract taurine technological method, make the production of taurine increase again new approach.
Embodiment
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, and a kind of method of extracting taurine from oyster, shells oyster, pulverizes, and gets 10 kilograms, oyster slurries, puts into container and adds the water of 60 kilograms, and heating in water bath to 80 ℃, is hydrolyzed 2 hours.Filter, filter residue is added to the water of 40 kilograms, continue heating in water bath to 80 ℃, be hydrolyzed 2 hours.Filter, merge filtrate twice, with hydrochloric acid, adjust pH value to 2.5, filter, by filtrate evaporation concentration, crystallization, and reclaim hydrochloric acid, be taurine crude product, taurine crude product is to taurine fine work 4 times by 95% washing with alcohol.
Claims (5)
1. from oyster, extract a method for taurine, it is characterized in that raw materials used oyster, through pulverizing, heavy, the crystallization of hydrolysis, acid, washing and taurine.
2. a kind of method of extracting taurine from oyster according to claim 1, is characterized in that described hydrolysis is that oyster is shelled, and pulverizes, and puts into container and adds the water of 4-10 times of quality, and heating in water bath to 80 ℃, is hydrolyzed 2 hours.
3. filter, filter residue is added to the water of 2-6 times of quality, continue heating in water bath to 80 ℃, be hydrolyzed 2 hours.
4. a kind of method of extracting taurine from oyster according to claim 1, is characterized in that it is to 2-5 with the filtrate pH value after hydrochloric acid adjustment merging that described acid is sunk.
5. a kind of method of extracting taurine from oyster according to claim 1, is characterized in that described washing is by 95% washing with alcohol 4 times for taurine crude product.
