Abstract

The invention discloses a preparation method for sea cucumber peptide, belonging to the technical field of aquatic product processing. The preparation method comprises the following steps: weighing cooked fresh sea cucumber without internal organs, immersing the sea cucumber in liquid nitrogen, taking the sea cucumber out, then soaking the sea cucumber in hot water with a temperature of 95-97 DEGC, and then carrying out stirring and washing; adding the cleaned sea cucumber into a cooking and enzymolysis tank for cooking, and after completion of cooking, starting the stirrer and the shearer ofthe cooking and enzymolysis tank and performing shearing to obtain slurry; filtering the slurry, then pumping the filtered slurry into the cooking and enzymolysis tank, adding composite neutral protease consisting of thiol protease-series bromelain, papain and Bacillus subtilis-produced neutral protease, and carrying out enzymolysis under a heat-preserved condition; and subjecting an enzymolysisproduct to post-treatment to obtain a finished sea cucumber peptide product. With the method in the invention, harmful heavy metals in a sea cucumber raw material can be completely removed; small-molecular peptide with a molecular weight of 1000 D or below in the enzymolysis product accounts for 85% or more; and the finished product has no fishy and peculiar smell.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a preparation method of sea cucumber peptide. Background technique [0002] Sea cucumber (Acaudina molpadioides Semper) belongs to the order Molpadida (Caudinidae), commonly known as fragrant ginseng. It is rich in the intertidal zone of the subtropical sandy sea area, especially in the East my country Sea area of ​​China. The current reserve is about 1 million tons, with an annual catch of about 3,000 tons. [0003] According to historical records and modern scientific research, East China Sea sea cucumber is an excellent food with the same source of medicine and food, high in protein and low in fat, and rich in nutrition, such as rich in arginine, sea cucumber saponins, and sea cucumber polysaccharides. Due to the large molecular weight of sea cucumber protein, direct consumption is not easy to be absorbed by the human body. With the development of deep proce...
