Abstract

The invention discloses a preparation method of patinopecten yessoensis gonad zymolyte / kappa-carrageenan mixed gel, and belongs to the technical field of marine resource development and utilization processing. The method includes the steps: raw material pretreatment; enzymatic hydrolysis reaction; zymolyte freeze-dried powder preparation; kappa-carrageenan water solution preparation; mixing; bubble discharging. According to the method, enzymolysis of patinopecten yessoensis gonad is implemented by trypsin, the patinopecten yessoensis gonad and the kappa-carrageenan are mixed according to a certain proportion, novel gel is prepared by a heating, swelling and gel cooling method, and the gel property of the novel gel is improved by adding saline ions. The method is simple in step and convenient to operate, time and labor are saved, the prepared novel gel has the advantages of high elasticity and high strength, the novel gel has high nutritive values and wide application prospects and canserve as raw materials of edible glue industry, and types of edible glue products are enriched.

Description

technical field [0001] The invention relates to the technical field of marine resource development, utilization and processing, and more specifically relates to a method for preparing a scallop gonad hydrolyzate / κ-carrageenan mixed gel. Background technique [0002] Scallops are delicious, nutritious, and have special health and medicinal effects, so they are as famous as sea cucumbers and abalones, and are listed as three treasures in seafood. The artificial cultivation of scallops in my country began in 1968. With the continuous improvement of breeding technology, the scale of scallop cultivation has been continuously expanded, and the output has been increasing year by year. It has become a key economic shellfish species in coastal aquaculture in my country, and its cultivation has achieved remarkable results economic benefits. [0003] In 2016, my country's scallop farming output reached 1.8 million tons. With the expansion of the scale of scallop farming and the improv...
