Abstract
The invention discloses a kind of method that taurine is extracted in processing byproduct from shellfish, step is：Shellfish processing byproduct is cleaned into defibrination；Water is added, shellfish processing byproduct is 1 with water weight part ratio:1-2,80 DEG C of heating 1h of constant temperature, 4 layers of filtered through gauze, filtering residue are added water, and filtering residue is 1 with water weight part ratio:0.5-1,80 DEG C of extraction 30min of constant temperature, filters, merging filtrate；Filtrate heating is concentrated into into the 1/6 of original volume, 1 is added:1 hydrochloric acid adjusts ph3-4,5000-7000r/min centrifugation 20min remove acidic protein, ph to 10 is adjusted with the sodium hydroxide of 5mol/L again, 5000-7000r/min centrifugation 20min remove basic protein, adjust ph to 6 and obtain first time concentrated solution, heating again is concentrated into the 1/5 of the first time volume of concentrate, repetition is above-mentioned except acidic protein and basic protein step, ph is adjusted to 6, second concentrated solution is obtained；Second concentrated solution adds 3 times of volume dehydrated alcohol, stands 4 DEG C of environment 12h, separates out taurine crystal.The present invention is added without any toxic reagent, and production process non-environmental-pollution, equipment simple operationss are easy.
Description
Technical field
The present invention relates to a kind of method that taurine is extracted in processing byproduct from shellfish, belongs to marine organisms processing technique field.
Background technology
Taurine earliest by separating in Calculus Boviss, therefore is gained the name also known as beta-amino ethyl sulfonic acid.Taurine is present in human body in a free form, is not involved in the synthesis of vivo protein, but but closely related with the metabolism of cystine, cysteine etc., and human body meets body requirement by the taurine in intake food.Taurine can be extracted from natural goodses, also chemically synthesized, but synthesis material toxicity is larger, for a long time, extract taurine paid attention to by people from natural goodses always.Taurine is relatively decentralized in natural biological, and also content is more rich in limited natural goodses is marine site, shellfish, Thallus Porphyrae for the amount extracted from natural biological.Although natural taurine price is higher, production process green, environmentally safe, with the biological activity that artificial chemistry synthesis does not have, these characteristics make natural taurine possess extensive market prospect.
The content of the invention
A kind of the technical problem to be solved extracts taurine method in being to provide processing byproduct from shellfish.
The solution of above-mentioned technical problem is to employ following technical measures：A kind of method that taurine is extracted in processing byproduct from shellfish, key step include：
（1）Shellfish processing byproduct is cleaned, defibrination；
（2）Water is added to shellfish processing byproduct, shellfish processing byproduct is 1 with water weight part ratio:1-2,80 DEG C of heating 1h of constant temperature, 4 layers of filtered through gauze, filtering residue are added water, and filtering residue is 1 with water weight part ratio:0.5-1,80 DEG C of extraction 30min of constant temperature, filters, merging filtrate；
（3）Filtrate heating is concentrated into into the 1/6 of original volume, 1 is added:1 hydrochloric acid adjusts ph3-4,5000-7000r/min centrifugation 20min remove acidic protein, ph to 10 is adjusted with the sodium hydroxide of 5mol/L again, 5000-7000r/min centrifugation 20min remove basic protein, adjust ph to 6 and obtain first time concentrated solution, heating again is concentrated into the 1/5 of the first time volume of concentrate, repetition is above-mentioned except acidic protein and basic protein step, ph is adjusted to 6, second concentrated solution is obtained；
（4）Second concentrated solution is added into 3 times of volume dehydrated alcohol, 4 DEG C of environment 12h are statically placed in, you can taurine crystal is separated out.
The present invention therefrom extracts taurine using the waste by-product after shellfish processing using these side-products as raw material; the present invention is added without any toxic reagent, and production process also non-environmental-pollution, equipment simple operationss are easy; and marine resources utilization is improve, reduce environmental pollution.
