Abstract

The invention discloses compound fresh-keeping liquid for chilled duck meat as well as a preparation and the application of the compound fresh-keeping liquid. Per 100 mL of compound fresh-keeping liquid for chilled duck meat comprises nisin accounting for 0.05 to 0.1g, chitosan mother liquor accounting for 5 to 10g, sodium lactate accounting for 4 to 4.8g, clove leaching solution accounting for 4.2 to 6g, cassia bark leaching solution accounting for 3.6 to 6g, pH conditioning agents accounting for proper quantities, and the rest is water. Secondary fresh-keeping treatment comprising soaking and spraying is adopted, the compound fresh-keeping liquid is applied to antisepsis and fresh preservation of chilled duck meat, and the synergistic action among different antiseptic bacteriostatic agents can be exerted; meanwhile, the double fresh-keeping treatment can inhibit the growth of special putrefying bacteria in chilled duck meat more effectively, such as pseudomonas, lactic acid bacteria, aeromonas veronii, brochothrix thermosphacta, enterobacterium and staphylococcus; and in addition, original quality and color of duck meat can be kept, and the conventional shelf life for chilled duck meat can be prolonged to reach about 10 days.

Description

technical field [0001] The invention relates to a composite fresh-keeping liquid for food, in particular to a composite fresh-keeping liquid for chilled duck meat, a preparation method and application thereof, and belongs to the technical field of meat product processing. Background technique [0002] my country is the world's largest meat duck breeding and production country, and the source of ducks is sufficient. Chilled duck not only has the appearance, soft texture, and delicious taste of fresh duck meat, but also has the characteristics of safety of frozen meat, long shelf life, less juice loss, high nutritional value, and convenient for various deep processing. Therefore, it is of positive and far-reaching practical significance to process meat ducks into chilled ducks, do a good job in antisepsis and preservation of chilled ducks, and extend their shelf life. [0003] How to effectively control the quality of chilled meat and prolong the shelf life has become an urge...
