A method for producing collagen fertilizer and co-producing chicken oil and calcium powder

Abstract

The invention discloses a method for preparation of a collagen feed and combined production of chicken oil and calcium powder. The method is characterized by comprising the following steps: (1) raw material processing, (2) chicken oil preparation, (3) two step enzymolysis, (4) the preparation of soluble calcium powder, (5) the preparation of a collagen culture medium, (6) inoculation of a strain, and (7) fermentation for preparation of the fertilizer. According to the method, a two step composite enzymolysis technology is used, an enzymolysis protective agent is added in the enzymolysis process, the collagen quality is improved, and the good quality of the product is guaranteed. The soluble calcium is prepared by citric acid activation, so that the biological absorption rate of calcium is improved. By using of activated carbon for deodorization, the product content is improved, and at the same time the process time is shortened. The feed produced by the method contains the collagen, and has the advantages of being nutritional and healthy, capable of preventing and curing diseases, and improving the quality of meat. The production process is clean, green, non-pollution, and free of waste water discharge, and the clean comprehensive utilization of 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 fertilizer and co-producing chicken oil and calcium powder. 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...

Problems solved by technology

[0004] 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 led to 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.

[0005] 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 very low. In order to utilize a large amount of chicken bones and realize clean industrialized mass production, an integrated production method is required
