Abstract

The invention discloses a method for extracting a nutrient solution from marine wastes. The method comprises the following steps: (I) pretreating marine wastes, namely removing obviously decayed partsin shellfish shells and marine wastes, and grinding the marine wastes into particles with the size of 5-10mm; (II) adding trypsin into 50-70 weight parts of the marine wastes in the step I, and performing inactivation after enzymolysis; (III) adding alkaline protease into 100-120 weight parts of the marine wastes in the step I, and performing inactivation after enzymolysis; (IV) mixing the enzymolysis mixture of the steps II and III, inoculating Kodamaea ohmer, and performing inactivation after fermentation; and (V) filtering the fermentation mixture obtained in the step IV, thereby obtainingthe nutrient solution. According to the method disclosed by the invention, the prepared extract is enriched in nutrient substances such as polypeptides, free amino acids and soluble proteins, and thehistamine content is low. The method disclosed by the invention is reasonable in process, advanced in technology and high in operability and can be applied to processing of the marine wastes.

Description

Technical field [0001] The present invention relates to a method for preparing peptides or proteins using fermentation or / and enzyme methods, in particular to a method for extracting nutrient solution from marine waste. Background technique [0002] We know that a large amount of seafood waste is produced in the fishery production process, which not only wastes resources but also pollutes the environment. If the targeted development of seafood waste can be designed, it will greatly save natural resources and bring good economic benefits. [0003] In the process of economic development of seafood waste, a major difficulty is that the freshness of seafood waste is often difficult to guarantee. Compared with the normal raw materials of seafood, seafood waste needs to be collected, aggregated and used for subsequent processing from different production facilities and different production steps. During this process, it may have a slight autolysis phenomenon, and cause the histamine co...
