Method for making collagen protein film coproduction organic compounds

Abstract

The invention discloses a method for making collagen protein film coproduction organic compounds. The method is characterized by comprising the following steps: (1) processing raw materials; (2) preparing chicken oil; (3) performing two-step enzymolysis; (4) preparing soluble calcium powder; (5) making composite liquid; and (6) making protein films. According to the method disclosed by the invention, the adoption of a two-step enzymolysis technique, the quality of collagen is improved; at the same time, enzymolysis protective agents are added into the enzymolysis process, so that the excellent quality of products is ensured; and calcium in the chicken bones is prepared into soluble calcium through acid activation on citric acids, so that the biological absorption rate of the calcium is increased. Dialdehyde starch is added, so that the mechanical property, the heat stability and the moisture resistance of the collagen are greatly improved; the collagen is easy to degrade, and the collagen has excellent environmental protection performance; and the production process is clean, green and pollution-free, no waste water is drained, and the purpose of the clean comprehensive utilization of the chicken bones is realized.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of agricultural and sideline products, and relates to a method for producing collagen film and co-producing organic matter. 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] At present, in the process of producing hydrolyzed collagen at home and abroad, most of the hydrolyzed collagen obtained by hydrolyzing animal bones, skins and other tissues by conventional methods has a wide molecular weight range and poor molecular weight uniformity; moreover, a large number of free amino acids produced during the hydrolysis proces...

Problems solved by technology

[0006] 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.

[0007] 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 benefits, social benefits and environmental benefits are very low. In order to utilize a large number of chicken bones and realize clean industrialized mass production, a reasonable and comprehensive utilization production method is necessary.
