Abstract

The invention discloses a preservative and a fresh-keeping method for improving refrigerating fresh-keeping effect of fresh shrimps. The invention is characterized in that: the preservative is a plant essential oil soaking solution; the plant essential oil soaking solution is obtained by diluting a plant essential oil compound solution with water until the concentration of a mixture is 4-6ml/L; the plant essential oil compound solution consists of the following components in percentage by weight: 50 to 60 percent of tea tree essential oil, 25 to 35 percent of clove essential oil, 10 percent of eucalyptus leaf essential oil and 5 percent of torreya grandis essential oil; and the fresh-keeping method comprises the following steps of: soaking the fresh shrimps into 4-6ml/L plant essential oil soaking solution for 8 to 12 minutes, packing with fresh-keeping bags containing 0.8 to 1.2 mass percent inorganic nano antibacterial agent, and refrigerating at a low temperature. The invention hasthe advantages that: the quality guarantee period of the fresh shrimps treated and packed by using the method can be prolonged in the refrigerating process, good appearance and mouthfeel of the freshshrimps are maintained, and the normal flavor of the shrimps is not affected; and the raw materials for the preservative are green and edible, so the preservative is safe and does not harm human body.

Description

technical field [0001] The invention relates to an anti-corrosion and fresh-keeping technology for aquatic products in the field of food processing, in particular to a fresh-keeping agent and a fresh-keeping method for improving the cold-keeping and fresh-keeping effect of fresh shrimp. Background technique [0002] Shrimp is an important class of aquatic products, with rich and comprehensive nutrients, high protein content, a complete range of amino acids, high unsaturated fatty acids, and a variety of vitamins necessary for human metabolism, with high nutritional value , is deeply loved by consumers for its delicious taste and high nutritional value. In recent years, the cultivation and consumption of shrimps in my country have continued to increase. However, as a general characteristic of aquatic products, shrimp is extremely susceptible to bacterial infection and spoilage due to its high moisture and protein content during fresh-keeping storage and transportation. At the...
