Embodiment 1

[0064] A preparation method utilizing animal cartilage to produce chondroitin sulfate and collagen peptides respectively, comprising the steps of:

[0065] (1) Cartilage treatment: Put 4500Kg of fresh bovine nasal bone into a 10000L reactor, add purified water to 9000L, and adjust the temperature of the feed liquid to 36.9°C.

[0066] (2) Use acetic acid to adjust the pH value of the feed solution to 4.5, extract at 36.9°C for 8 hours (use acetic acid to maintain the pH value of 4.5±0.2 during the extraction process), and after the extraction is completed, transfer the extract solution and filter it with a plate and frame Machine filter to get the extract, and the extract enters the next process. The remaining cartilage goes to another process.

[0067] Extraction treatment:

[0068] (2a) Concentrate the extract by ultrafiltration until the volume of the filtrate is 1 / 4 of the volume of the extract, then transfer the filtrate to an alcohol precipitation tank, start stirring ...

Abstract

The invention discloses a preparation method for respectively extracting chondroitin sulfate and collagen peptide from animal cartilage (cattle, pigs, sharks and the like). The preparation method comprises the following steps of performing leaching and extraction on animal cartilage raw materials with acetic acid, performing ultrafiltration and concentration on raffinate to obtain a concentrated solution A, performing ethanol precipitation, refining, filtration, ethanol precipitation, dehydration and drying on the concentrated solution A to obtain the chondroitin sulfate; and performing hydrolysis on surplus cartilage ingredients in a reaction kettle with proteases, then performing filtration, adding activated carbon, performing adsorption and filtration, performing nanofiltration and concentration, performing double-effect concentration, and performing spray drying so as to obtain collagen polypeptide. According to the preparation method disclosed by the invention, the high-value utilization of cartilage resources is realized, the chondroitin sulfate and the collagen peptide can be extracted and separated efficiently at the same time, the added value of products can be increased,and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a processing technology of animal cartilage, in particular to a method for extracting chondroitin sulfate and collagen peptides respectively by using animal cartilage, in particular to extracting chondroitin sulfate with acetic acid extraction and then extracting collagen peptides with enzymatic hydrolysis A production process. Background technique [0002] my country is a populous country with relatively developed agriculture and animal husbandry and rich cartilage resources. Active ingredients such as chondroitin sulfate and collagen rich in animal cartilage, throat bone, nasal bone and trachea have been widely used in the fields of medicine, health food, cosmetics and food. [0003] Chondroitin Sulfate (CS) is an acidic mucopolysaccharide composed of repeating disaccharide units composed of D-glucuronic acid and N-acetylgalactosamine. It contains 50-70 disaccharide basic structures with a molecular weight between 10,000-50...
