Novel preparation method for natural taurine

Abstract

The invention provides a novel preparation method for natural taurine. The novel preparation method comprises the following steps: collecting an aquatic product water extract, concentrating the aquatic product water extract, obtaining precipitates and liquid supernatant after adding alcohol, and concentrating the liquid supernatant after extracting the liquid supernatant; putting the obtained concentrated liquor to crystallize under a low-temperature environment to obtain a taurine crude product; re-crystallizing the taurine crude product to obtain a wet fine product, and drying the wet fine product to obtain a finished product. The novel preparation method aims to overcome the problems that raw materials for preparing the natural taurine by a current biological extraction method are less in source and relatively high in price, overcome the problems that a process for preparing the natural aurine by adopting a conventional ion exchange method is complex in process, needs large-scale equipment, is high investment, high in cost and large in environmental pollution, and overcome the defects that a current simple prperation method for preparing the natural taurine is large in alcohol consumption amount and relatively difficult to realize industrialization.

Description

technical field [0001] The invention relates to the field of marine product processing, and more specifically relates to a new method for preparing natural taurine by using leftovers produced during the processing of aquatic products as raw materials. Background technique [0002] In recent years, the demand for taurine has exploded. At present, the annual consumption of taurine in the world has exceeded 20,000 tons, and more than 80% of the annual consumption is used as food nutritional additives. The consumption is mainly concentrated in the United States, Japan and other countries. At present, the United States, Japan and other countries have clearly stipulated that taurine must be added to infant and children's food. In Japan, the per capita annual consumption of taurine for children is more than 500 grams. my country is a huge potential market: there are nearly 1.3 billion people and 380 million children. If 1 / 3 of the children supplement 300 grams of taurine every yea...

Problems solved by technology

The disadvantages of this patent are: 1. The operation of "immediate suction filtration and impurity removal" described in the above-mentioned patent effectively removes a large amount of impurities, but it is difficult to realize in industrial production; 2. The crystallization and recrystallization steps also need to consume a large amount of Ethanol, ethanol consumption is large, the production cost is high, and the entire crystallization and recrystallization process must be designed in an explosion-proof environment, which increases production investment
