A method for extracting organic matter such as collagen in chicken bone

Abstract

The invention discloses a method for extracting collagen and other organic matter in chicken bones, which is characterized in that the steps are as follows: (1) raw material treatment (2) preparation of chicken fat (3) two-step enzymatic hydrolysis (4) preparation of soluble calcium powder (5) Preparation of collagen. The invention better maintains the functional characteristics of various substances in the chicken bone, and the obtained chicken oil keeps the original flavor of the chicken oil to the greatest extent. The two-step compound enzymatic hydrolysis technology improves the quality of collagen, and then activates the calcium in the chicken bone by citric acid to prepare soluble calcium, which improves the bioabsorption rate of calcium. The invention uses food-grade protease to undergo enzymolysis under mild conditions, and has high safety and no side effects. The preparation method is simple and easy, the cost is low, the production process is clean, green and pollution-free, without any waste water discharge, the clean and comprehensive utilization of chicken bones is realized, the chicken bones are suitable for large-scale industrial production, and the economic and social benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of agricultural and sideline products, and relates to a method for extracting organic matter such as collagen in chicken bones. Background technique [0002] Collagen is one of the main components of the human tissue structure. It spreads throughout the various tissues and organs of the body, such as: skin, bones, cartilage, ligaments, cornea, various endometrium, fascia, etc., and is responsible for maintaining the shape and structure of skin and tissues and organs. It is also an important substance for repairing various damaged tissues. [0003] Existing collagen is mainly extracted from animal bodies, such as extracting collagen and chondroitin sulfate from bovine cartilage in Chinese patent 200710040969.1, extracting collagen from pig, cattle, and sheep bones in Chinese patent 201110090110.8, and extracting collagen from chicken bones in However, the annual output of broiler chickens i...

[0003] Existing collagen is mainly extracted from animal bodies, such as extracting collagen and chondroitin sulfate from bovine cartilage in Chinese patent 200710040969.1, extracting collagen from pig, cattle, and sheep bones in Chinese patent 201110090110.8, and extracting collagen from chicken bones in However, the annual output of broiler chickens in my country has reached more than 8 million tons, and the processing of chicken parts has resulted in the accumulation of a large number of chicken skeletons. 90% of the protein in chicken bones is collagen, but it has not been well valued and comprehensively utilized.

[0004] From above-mentioned prior art, extract collagen production method from animal bone mainly to only produce single collagen product, adopt chemical method, use chemical reagents such as strong acid and strong alkali, pollute seriously, can cause collagen protein simultaneously Denaturation, economic benefit, social benefit and environmental benefit are all very low, in order to utilize a large amount of chicken bones, realize clean industrialized batch production, just must a kind of production method of reasonable comprehensive utilization, but there is no report in the prior art
