Modified atmosphere packaging of chicken
What is White-striped chicken
White-striped chicken refers to the chicken that has stripped off its feathers, removed its internal organs, and has been cleaned. When you buy it home, you can cook and process the chicken as long as you cut it off. Because of its soft connective tissue, uniform fat distribution, rich in vitamins and indispensable trace elements and creatine (IMP), chicken has the nutritional characteristics of high protein, low fat, low calories and low cholesterol, chicken has become the second largest meat product in the world after pork, maintaining an annual consumption growth rate of 3%.
Why choose modified atmosphere Packaging?
Modified atmosphere packaging inhibits the propagation of microorganisms through low oxygen and high carbon dioxide combined with low temperature temperature control; through slaughtering and processing to the whole low temperature of packaging to inhibit the enzyme activity of the product and prevent the loss of nutrients; by controlling the total number of initial bacteria of the product, improve its stability and prolong the fresh-keeping time limit. As a result, the fresh-keeping time of white-striped chicken is more than 7 days. The untreated chilled chicken can only be stored for 3 or 4 days.
Modified atmosphere fresh-keeping method of White-striped Chicken
The pre-sterilized white-striped chicken is put into the packaging container for modified atmosphere packaging, and the packaging container is filled with a mixture of nitrogen and carbon dioxide, in which the atmosphere ratio is 60% of nitrogen and 40% of carbon dioxide. The packaged white-striped chicken is refrigerated in a freezer at 0 ℃. The fresh-keeping period of the white-striped chicken with modified atmosphere packaging is greatly prolonged, at the same time, the nutrition of the white-striped chicken is not lost, which ensures the quality of the product.
Significance of modified atmosphere Packaging for Poultry
As the consumption market prospect of chicken products is considerable and the market potential is huge, the demand for chilled chicken will continue to increase. The invention is suitable for the fresh-keeping processing of bulk broilers, has good popularizing value, and has a wide application prospect.
