Embodiment Construction

[0010] Take 1000g of commercially available hemp stingers pickled with three alums, drain, soak in 2-5 times the amount of deionized water, and change the water every 2-3 hours until the content of sodium chloride in the soaking water is lower than 1.5 Up to ppm (chloride ion test was negative). The soaked desalted jellyfish adjusts the pH to 5.8-6.8 (the optimum pH of a special composite collagenase), and digests it at 38-40°C (the optimum temperature of the collagenase) for 12-16 hours to obtain a clarified The transparent liquid is the hydrolyzed collagen solution; the hydrolyzed collagen solution is freeze-dried to obtain 20 g of hydrolyzed collagen powder solid with a purity of more than 95% and peptides with a molecular weight below 3000 accounting for more than 85%.

Abstract

The invention discloses a process for preparing hydrolyzed collagen protein using jellyfishes as the raw material, and belongs to the natural resource processing as well as utilizing technical field. The invention uses a novel natural marine biological resource, i.e. jellyfishes, as the raw material for preparing hydrolyzed collagen protein, and realizes the conversion of the role of the jellyfishes from a marine ecological disaster species to a novel natural marine biological collagen protein resource. By operating according to the invention, 2 percent of hydrolyzed collagen protein with more than 95 percent of purity, less than 3000 molecular weight and more than 85 percent of peptides can be obtained. The hydrolyzed collagen protein is known as an important healthy food and cosmetic raw material, and has wide range of application in the clinical medicine, the textile industry and the fine chemical industry, etc. Developing and utilizing the jellyfishes used as the natural marine biological resource has great significance to the fast growing of the jellyfishes, in order to the effective protection of marine ecologic environment of China and to the rapid recovery of the marine fishery.

Description

technical field [0001] The patent relates to a process for preparing hydrolyzed collagen with jellyfish as a raw material, which belongs to the technical field of processing and utilization of natural resources. Background technique [0002] Cyanea, commonly known as hemp sting, is a large marine plankton belonging to Phylum Cnidaria, Class Scyphomedusae, Order Phylum cnidaria, Family Cyanea). There are four species of white jellyfish (Cyanea nozaki Kishinouye), hair-shaped jellyfish (Cyanea capillata), brown jellyfish (Cyanea ferruginea Eschscholtz), and purple jellyfish (Cyanea purpurea Kishinouye) that have been found along the coast of my country. The largest number and the widest distribution range. The jellyfish usually uses small zooplankton as bait. Its gonads are well developed, its reproductive ability is strong, and its growth rate is extremely fast. At present, the annual output of jellyfish in my country has reached 10 million tons, which constitutes a new natu...
