Method for decoloring chicken bone muddy flesh by using sodium hydrogen carbonate solution

Abstract

The invention relates to the technical field of meat processing and particularly relates to a method for rinsing and decoloring chicken bone muddy flesh by using a sodium hydrogen carbonate solution. The method comprises the following steps: mixing unfrozen chicken bone muddy flesh at a relatively low temperature or fresh chicken bone muddy flesh with a prepared NaHCO3 solution at a certain concentration and pH in advance according to a certain feed liquid ratio; and slowly stirring to dissolve main color generating matters in chicken bone muddy flesh: hemoglobin, myohemoglobin and part of impure pigments under an alkaline condition and centrifuging to remove the matters so as to achieve the decoloring request. The mass concentration of the NaHCO3 solution is 0.05-0.125%. According to the decolored chicken bone muddy flesh, not only is the whiteness greatly improved, but also objectionable odor can be removed to a certain extent. The decoloring method provided by the invention is simple to operate, settles a matter at one go, and is good in effect and suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of meat processing, in particular to a method for rinsing and decolorizing chicken bone puree with sodium bicarbonate solution. Background technique [0002] In recent years, my country's poultry farming industry has developed rapidly, especially chicken production ranks among the top in the world. As one of the largest poultry producing countries in the world, my country's broiler production has increased from 1.39 million tons in 1984 to 13.7 million tons in 2012. With the development of deep processing of chicken, chicken products in small packages have become the mainstream trend, which leads to a large number of surplus chicken skeletons. The chicken skeleton accounts for about 20%-22% of the whole chicken. At present, the bone meat separator is mainly used to recycle the chicken on the chicken skeleton, which can produce about 60%-65% chicken bone meat. Therefore, nationwide, the annual output of ch...

However, since the main component of chicken bone paste is the minced chicken attached to the chicken skeleton and the bone-meat mixture obtained by superfine grinding of some chicken bones, during the process of making chicken bone paste, a large amount of blood on the chicken skeleton will remain in the chicken. In bone meat paste, its color is too different from that of ordinary chicken, and a large amount of hemoglobin contained in chicken bone paste is easy to oxidize and change color in the air, resulting in darker color of chicken bone paste products, which reduces consumer acceptability and limits The amount of chicken bone and meat puree added in food production
