Problems solved by technology

[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 fish 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

Embodiment 1

[0017] Put 4 tons of chicken bone raw materials into the cutter at a constant speed and cut them off, transport them to the meat grinder, and add water continuously at the same time. When feeding, the water temperature is controlled at 55°C, and the mass ratio of feed to water is controlled at 1:1.0; after confirming the 10-ton hydrolysis tank In the case of cleaning, add 300L of bone slag cleaning water to the bottom of the hydrolysis tank, put the bone slag obtained in step 1 into the hydrolysis tank, add bone slag cleaning water into the hydrolysis tank, and raise the temperature to 85°C after feeding, keep warm and stir for 3 hours, After stopping the stirring, let it stand for 20 minutes, and directly separate the chicken fat floating on the upper layer; the separated chicken fat enters the oil storage tank, turn on the jacket steam and stir, the temperature rises to 90°C, and then stand for sterilization for 4 hours until the fat layer is completely separated , open the b...

Embodiment 2

[0019] Put 1,000 kg of chicken bone raw material into the cutting machine at a constant speed and cut it, transport it to the meat grinder, and add water continuously at the same time. When feeding, the water temperature is controlled at 65°C, and the mass ratio of material to water is controlled at 1:1.1, that is, the weight of water is controlled at 110. kg; after confirming the cleanliness of the 3-ton hydrolysis tank, put the bone slag obtained in step 1 into the hydrolysis tank, add 100L bone slag cleaning water into the hydrolysis tank, and raise the temperature to 90°C after feeding, keep warm and stir for 3.5h, stop After stirring, let stand for 25 minutes, separate the slick oil on the upper layer, and the separated chicken oil will enter the oil storage tank, turn on the jacket steam and stir, after the temperature rises to 100°C, let stand for sterilization for 3 hours, until the fat layer is completely separated, open the tank The bottom valve discharges the water p...

Abstract

The invention discloses a method for simultaneously producing collagens, chicken oil and high-calcium powder through using chicken bones. The method comprises a step of raw material treatment, a step of chicken oil separation, a step of chicken oil preparation, a step of two-step enzymatic hydrolysis, a step of high-calcium powder separation, and a step of collagen preparation. The method which utilizes the above six steps has the advantages of realization of the clean comprehensive utilization of the chicken bones, clean, green and pollution-free production process, no wastewater discharge, improvement of the quality of the collagens, suitableness for the large-scale industrialized production, and substantial economic and social benefits.

Description

technical field [0001] The invention relates to a method for co-producing collagen, chicken oil and high-calcium powder from chicken bones, and belongs to the field of comprehensive utilization of agricultural and sideline products. 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 fish bones in However, the annual output of bro...
