Embodiment Construction

[0031] In order to illustrate the purpose of the present invention and the technical effects of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The invention provides a method for extracting taurine by water dissolution and an ion exchange technology for extracting natural taurine from octopus leftovers. The steps are to wash the raw materials to make a homogenate, add distilled water to extract the taurine in the octopus leftovers under high temperature and constant stirring, obtain the extract and solid materials through centrifugation, and filter the extract to obtain clarification. Liquid and clarified liquid are separated by isoelectric point precipitation method to separate the water-soluble protein contained therein to obtain a separated liquid containing taurine and other amino acids and a small amount of inorganic salts. The separated octopus protein ...

Abstract

The invention discloses a method for extracting and separating natural taurine from octopus leftovers. The method comprises the following steps that: raw materials is washed clean and made into taurine-extracting solution; water soluble protein is separated out from the solution by an isoelectric-point precipitation method, and separation liquid containing taurine, other amino acids and a small amount of inorganic salt is obtained; through the different characteristics of anion-cation exchange resin, the taurine, the other amino acids and the inorganic salt are separated by use of the anion-cation exchange resin; an separated amino-acid solution can be utilized for other aims after collection; cation adsorption taurine is eluted by use of hot deionized water; eluent obtained through collection is concentrated, added with ethanol and crystallized at a low temperature so as to precipitate the taurine; and the precipitated taurine is separated out, recrystallized and purified so as to obtain high-purity acicular natural taurine crystals. The method has the advantages of succinct operation, short cycle, high value, no pollution and the like, greatly improves the utilization value of the octopus leftovers, and increases the technological content of octopus processing.

Description

Technical field: [0001] The invention relates to a method for extracting and separating natural taurine, in particular to a method for extracting and separating natural taurine from octopus leftovers by using isoelectric point precipitation and protein separation technology. Background technique: [0002] Taurine is a non-protein amino acid containing bovine. It is one of the main components of the precious medicinal material taurine and is widely used in food and medicine industries. [0003] Natural taurine mainly exists in the viscera of mammals, and it is relatively scattered and in small amount, which is far from meeting people's needs. Because octopus is an aquatic product with high natural taurine content in food, taurine is generally extracted from octopus leftovers, and then concentrated and refined. [0004] Although octopus leftovers contain extremely high taurine, due to the limitations of processing technology and equipment, it is generally difficult to further...
