Example Embodiment

[0028] Example 1. A method for producing boneless raw meat, chicken bone broth and chondroitin sulfate from chicken skeleton

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

[0030] The specific method is as follows:

[0031] 1. Pass the chilled chicken skeleton (-4℃-0℃) through the bone separator to separate 50%-60% product A cold fresh boneless raw meat and 40%-50% chicken bone residue, boneless raw meat It is a granular meat emulsion with a diameter of 0.8-1.0mm, which can be used as a raw material for meat processing.

[0032] 2. Put the separated chicken bone residue into a hot-pressure extraction tank, fix the ratio of chicken bone residue and water to 1:2, and perform hot-pressure extraction at a temperature of 125°C and an extraction pressure of 0.3MPa ±0.01MPa, the extraction time is 1.5h. After the extraction is completed, the pressure in the hot-pressure extraction tank is reduced by the method of interlayer cooling, the hot-pressure extraction tank is o...

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

[0038] 1. Effectiveness verification of co-production of boneless raw meat

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

[0040] Through the analysis, it can be known that 1Kg chicken skeleton can separate 0.5Kg-0.6Kg of deboned meat through the bone separator. The market pri...

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...
