Problems solved by technology

But at present, the utilization rate of chicken skeleton is relatively low, mainly used as chicken bone paste and feed processing, and secondly, a small amount is used for gelatin extraction, and the comprehensive utilization rate of chicken skeleton is relatively low; in terms of chicken cartilage utilization, most of them currently use acid-base The expensive chondroitin sulfate is extracted from the chicken breast cartilage by the method combined with the enzymatic method. Since the joint production cannot be realized, the bone enzymatic solution is treated as wastewater, resulting in resource consumption and environmental pollution.

Embodiment 1

[0028] Embodiment 1, a method for producing deboned raw meat, chicken bone broth and chondroitin sulfate from a chicken skeleton

[0029] according to figure 1 The process flow shown is carried out.

[0030] The specific method is as follows:

[0031] 1. Pass the chilled (-4°C-0°C) chicken skeleton through the bone and meat separator to separate 50%-60% of product A cold fresh deboned raw meat and 40%-50% chicken bone dregs, deboned raw meat The granular meat mince with a diameter of 0.8-1.0 mm can be used as a raw material for meat processing.

[0032] 2. Put the separated chicken bone slag into a hot-pressed extraction tank, fix the ratio of chicken bone slag and water to 1:2, and carry out hot-pressed extraction, the extraction temperature is 125°C, and the extraction pressure is 0.3MPa ±0.01MPa, the extraction time is 1.5h. After the extraction is completed, use the interlayer cooling method to reduce the pressure in the hot-pressed extraction tank, open the hot-pressed...

Embodiment 2

[0037] Example 2. Verification of a method for chicken skeleton co-production of deboned raw meat, chicken bone broth and chondroitin sulfate

[0038] 1. Validation of the effect of co-production of deboned raw meat

[0039] According to step 1 in the implementation case 1, after the chicken skeleton passes through the bone and meat separator, 50%-60% of the granular deboned raw meat can be separated, and 40%-50% of the chicken bone residue can be obtained. The size of the deboned raw meat is 0.8-1.0mm. The deboned raw meat is fresh in color and rich in nutrition. It is mainly rich in 22.39% crude fat, 12.52% crude protein, 63.89% moisture, 0.76% calcium, and 0.44% phosphorus. The deboned meat has good emulsification performance and can be used as conditioning meat Products and raw materials for Chinese and Western low-temperature meat products.

[0040]Through the analysis, it can be seen that 1Kg chicken skeleton can be separated into 0.5Kg-0.6Kg deboned meat through the b...

Abstract

The invention discloses a method for co-production of de-boned raw chicken, chicken bone soup-stock and chondroitin sulfate using chicken skeletons. The method comprises the following steps: putting the chilled chicken skeleton in a deboner to separate a product A de-boned raw chicken and chicken bone residues; processing the separated chicken bone residues through hot-pressing extraction, vibrating residue removal and oil-water separation to obtain a bone soup and chicken bone oil, adsorbing and eluting the bone soup by using macroporous resins to obtain a product B chondroitin sulfate; processing the deoiled bone soup remained after the resin adsorption through double effect concentration or MVR concentration, homogenizing and blending the concentrated bone soup and the chicken bone oil to obtain a product C chicken bone soup-stock. The co-produced de-boned raw chicken has a fresh color, rich nutrition, a good emulsifying property of the de-boned chicken, and the de-boned raw chicken can be raw materials for meat product processing. The co-produced chicken bone soup-stock product has a delicate taste, a rich chicken flavor, rich nutrition, and can be used as a natural soup base in food. The purity of the co-produced chondroitin sulfate is 87.41%, and the molecular weight is 5.283e[+4].

Description

technical field [0001] The invention relates to a method for co-producing boneless raw meat, chicken bone broth and chondroitin sulfate from chicken skeletons. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations, the output of chicken meat in the world's meat production has grown rapidly in the past 10 years, and the fastest growing region is Asia, while China's chicken output ranks second in the world. In 2009, my country's broiler chicken output was about 13.7 million tons , Chicken skeleton is the main by-product of poultry processing, accounting for about 25% of the total weight of chicken. my country's annual output of fresh chicken bones is about 1.37-4.11 million tons, which is very high. But at present, the utilization rate of chicken skeleton is relatively low, mainly used as chicken bone paste and feed processing, and secondly, a small amount is used for gelatin extraction, and the comprehensive util...
