Embodiment 1

[0035] (1) Raw material processing: remove the residual meat from the fresh anglerfish bone, and wash it in hot water at 40°C;

[0036] (2) Fishbone crushing: add NaOH solution accounting for 15% of the weight of the fishbone to the fishbone obtained in step (1), the concentration of the NaOH solution is 0.5mol / L, and add NaCl solution of 200% of the weight of the fishbone at the same time, The mass concentration of NaCl solution is 15%; Fishbone is pulverized with pulverizer, forms pulverizing liquid;

[0037] (3) Chondroitin Sulfate Extraction: Stir and extract the pulverized liquid obtained in step (2) at 50°C for 8 h, filter through a 150-mesh filter cloth, extract the obtained filter residue once more under the same conditions and filter, and combine twice The filtered filtrate is obtained as an extraction filtrate, and the filter residue obtained by the second filtration is collected for further extraction of collagen;

[0038] (4) Deproteinize the filtrate enzyme: adjust...

Embodiment 2

[0047] (1) Raw material processing: remove the residual meat from the fresh ray fish bones, and wash them in hot water at 50°C;

Abstract

The invention relates to the field of marine active substance preparation from aquatic animal processing byproduct sources, and aims to provide a simple and quick high-extraction-rate comprehensive utilization technique of marine fish bones. The technique provided by the invention comprises the following steps: processing the raw material, crushing the fish bones, extracting chondroitin sulfate, carrying out enzymolysis on the filtrate to remove proteins, inactivating enzymes at high temperature, precipitating the chondroitin sulfate, removing fat from the filter residues, extracting collagen, salting out the collagen, collecting collagen, dialyzing the collagen, and carrying out freeze-drying and the like. The invention is simple and quick, has the advantage of high extraction rate, and achieves the goal of simultaneously producing chondroitin sulfate and collagen.

Description

technical field [0001] The invention relates to the field of preparation of marine active substances derived from aquatic animal processing by-products, in particular to a comprehensive utilization process of marine fish bones. Background technique [0002] Chondroitin Sulfate (CS) is a kind of glycosaminoglycan, which is polymerized by D-glucuronic acid and N-acetyl-D-galactosamine with 1,3 glycosidic bonded disaccharide as the basic unit macromolecular polysaccharides. CS resources are abundant and widely exist in human and animal bones, cartilage, tendons, ligaments and other tissues. As a drug, CS is mainly used to treat arthritis and coronary heart disease, and also has certain effects on neuralgia, migraine, and atherosclerosis. Traditionally, chondroitin sulfate is mainly extracted from animal cartilage tissues such as pigs, cattle, and sheep, and the source and process are relatively simple. [0003] Collagen is the most abundant protein in animal sources, account...
