狐貉貂屠体加工工艺及品控研究

发布时间：2019-04-11 17:22

【摘要】：狐貉貂屠体一般作为动物源性蛋白来使用,其加工工艺多以压块冷冻或油榨法进行。但这两种方法都存在一定的缺陷,压块冷冻还需要配备冷库进行保存,增加资金投入,油榨法生产能力不高,对环境的污染大,得到的产品含水率高,不易保管和储存,且质量不稳定。本试验通过高温高压水解法的加工工艺,将狐貉貂屠体加工成动物性油脂和动物源性蛋白产品。对环境的污染小,产量高且质量稳定。既解决了昌黎县打皮季节大量毛皮动物屠体堆积造成的环境污染问题又适应我国动物源性蛋白和饲用油脂紧缺的国情。通过对狐貉貂屠体加工后的骨肉粉分析检验可知,产品中中重金属铜、铁、锰、锌、铬、镉、汞、砷、铅、氟的含量符合饲料及饲料添加剂的卫生指标;骨肉粉中含水量为7%;粗蛋白含量为40.0%;粗脂肪含量为11.2%;钙含量为12.2%;总磷为6.0%,符合饲料用肉骨粉的质量指标;动物性油脂中重金属铜、铁、锰、锌、铬、镉、汞、砷、铅、氟的含量符合饲料及饲料添加剂的卫生指标。本试验的结果表明,通过高温高压水解法生产的狐貉貂屠体产品可以作为动物源性蛋白饲料或饲料用油来加工利用,关键是重金属含量要符合国家规定标准。要做到这一点,就需要用管理生猪、肉鸡的饲料标准来管理狐貉貂饲料的生产和销售。避开伦理问题,狐貉貂屠体产品还可以在毛皮动物养殖领域作为动物的蛋白质补充料来加以利用。
[Abstract]:Fox raccoon mink carcass is usually used as animal-derived protein, and its processing process is mostly carried out by block freezing or oil pressing. But these two methods have some defects, the cryocryotherapy also needs to be equipped with cold storage, increase the capital input, the production capacity of the oil pressing method is not high, the pollution to the environment is large, the water content of the products obtained is high, and it is not easy to keep and store. And the quality is unstable. In this experiment, the carcass of the fox raccoon mink was processed into animal fat and animal-derived protein by high temperature and high pressure hydrolysis. The pollution to the environment is small, the output is high and the quality is stable. It not only solves the problem of environmental pollution caused by the accumulation of a large number of fur animal carcasses in Changli County, but also adapts to the shortage of animal-derived proteins and fodder oils in China. The results showed that the contents of heavy metals Cu, Fe, mn, Zn, Cr, CD, Hg, as, Pb, F in the products accord with the hygienic indexes of feed and feed additives. The content of water, crude protein, crude fat, calcium and phosphorus were 7%, 40.0%, 11.2%, 12.2%, 6.0% and 6.0%, respectively. The contents of heavy metals Cu, Fe, mn, Zn, Cr, CD, Hg, as, Pb, F in animal oils accord with the hygienic indexes of feed and feed additives. The results of this experiment show that the products produced by hydrolysis of high temperature and high pressure can be used as animal protein feed or feed oil. The key is that the content of heavy metals should meet the national standard. To do this, it is necessary to manage the production and sale of foxdog mink feed with feed standards for live pigs and broilers. To avoid ethical issues, fox raccoon mink carcasses can also be used as an animal protein supplement in fur breeding.
