Problems solved by technology

This kind of process is cumbersome and requires large-scale equipment, the cost is high, the ion exchange is used to remove impurities, the operation is complicated, and the regeneration of the ion exchange resin requires a large amount of acid and alkali, which pollutes the environment greatly.
The authorized patent (patent number: ZL201310283931.2) discloses a simple method for extracting natural taurine, which uses simple methods such as raw material pretreatment, ethanol removal of impurities, concentration, and crystallization to realize the preparation of taurine. The disadvantages are: ethanol impurity removal, crystallization, and recrystallization steps all need to add 3 to 4 times the volume of absolute ethanol, the consumption of ethanol is huge, the production cost is high, ethanol is flammable and explosive, and there are also great potential safety hazards
None of these patents or patent applications has developed and utilized taurine resources in abalone, resulting in a waste of resources, and the process is cumbersome and consumes a lot of energy.

Abstract

The invention provides a method for extracting taurine and polysaccharides from abalone's viscera simultaneously. The method comprises following steps: waste collection of viscera produced in an abalone processing process; water extraction; Ultra-fol ultrafiltration membrane treatment; enzymolysis; ethanol precipitation; concentration; crystallization; acquisition of high-purity taurine crystals after recrystallization. The method overcomes the technical defect that the taurine and the polysaccharides cannot be extracted simultaneously from the abalone's viscera with the conventional method and adopts the technical scheme including water extraction, Ultra-fol ultrafiltration membrane treatment, enzymolysis, ethanol precipitation, concentration and crystallization to extract the taurine and the polysaccharides from abalone's viscera simultaneously, so that the utilization rate of the abalone resources is increased effectively. The method solves the problems of complicated process, higher cost and serious environmental pollution during preparation of natural taurine with a traditional ion exchange method, overcomes the defect of large ethyl alcohol consumption during preparation of the natural taurine with a conventional simple preparation method and solves the problems of complicated process and large consumption of a conventional method for preparing the polysaccharides from abalone.

Description

technical field [0001] The invention relates to the field of marine product processing, in particular to a method for simultaneously extracting taurine and polysaccharides from abalone viscera. Background technique [0002] Abalone is popular at home and abroad for its unique flavor, texture and rich nutritional value. my country is the world's largest abalone farming country. In 2010, China's abalone farming output reached 56,500 tons, accounting for about 85% of the world's total output. In 2014, the national abalone production has exceeded 110,000 tons. At present, abalone is mainly sold fresh and canned products. With the increase of abalone production and the development of abalone processing industry, the deep processing of abalone is particularly important. In the process of abalone processing, a large amount of by-products such as soup and internal organs are often discarded, which not only causes waste of resources but also brings environmental pollution. On the ...
