A kind of sea cucumber peptide and its production method

Abstract

The invention belongs to the field of sea cucumber peptides, and discloses a sea cucumber peptide and a production method thereof. The production method of the sea cucumber peptide includes adding water to the sea cucumber raw materials, homogenizing the sea cucumber, heat treatment, enzymatic hydrolysis of the high-efficiency compound enzyme preparation without adjusting the pH value and controlling the temperature, and filtering through the inorganic nanofiltration ceramic membrane to remove the insoluble and Moisture-absorbing ingredients, high temperature and high pressure treatment, concentration and drying powder. The method provided by the present invention does not need to adjust the pH value of the enzymolysis, does not need to control the enzymolysis temperature, the enzymolysis time is short, the amount of enzyme added is small, the molecular weight of the enzymolysis product is low and concentrated, and the prepared sea cucumber peptide powder is water resoluble Excellent and not easy to absorb moisture and agglomerate during storage.

Description

A kind of sea cucumber peptide and production method thereof technical field The invention belongs to the field of sea cucumber peptide, particularly a kind of sea cucumber peptide and production method thereof. Background technique Sea cucumber, belonging to the class of sea cucumber, is a marine echinoderms living in the sea to 8000 meters, and has a history of more than 600 million years. Historically, sea cucumbers feed on seafloor algae and plankton. Sea cucumbers are covered with thorns all over the body and are widely distributed in the oceans of the world. South China Sea There are many kinds of sea cucumbers along the coast, about 20 kinds of sea cucumbers can be eaten. Sea cucumber is as famous as ginseng, bird's nest and shark's fin. It is one of the eight treasures in the world. one. Sea cucumber is not only a precious food, but also a precious medicinal material. According to the "Supplement to Compendium of Materia Medica": sea cucumber, sweet and sa...

Problems solved by technology

[0005] However, the problems and shortcomings of the above two invention patent applications are: the enzymatic hydrolysis efficiency of the enzyme used is low, the enzymatic hydrolysis time is long, the amount of enzyme added is large, the optimum pH value and optimum temperature need to be adjusted for enzymatic hydrolysis, and the operation is complicated , adjusting the optimum pH value of enzymolysis will bring in a large amount of inorganic ions, and controlling the optimum enzymolysis temperature consumes a lot of energy; two membrane filtrations with ultrafiltration membrane and nanofiltration membrane are required, and the role of ultrafiltration membrane is as follows: To intercept macromolecular substances, the role of nanofiltration membrane is desalination and concentration, the steps are cumbersome, and the membrane core used is organic material, which is not resistant to acid and alkali, high temperature and high pressure, small flux, short service life, and inconvenient cleaning; The water resolubility of the prepared sea cucumber peptide powder is poor, and it is easy to absorb moisture and agglomerate during storage
