Abstract

The invention discloses an aquatic product fresh-keeping agent which is formed by mixing the following components in percentage by weight: 20-30% of sodium tripolyphosphate, 20-30% of sodium pyrophosphate, 10-20% of sodium hexametaphosphate, 5-10% of dipotassium phosphate, 5-10% of trisodium phosphate and 10-20% of edible salt. A method for keeping aquatic products fresh by using the fresh-keeping agent comprises the following steps: 1) weighing clean aquatic products with an automatic weighing machine, and conveying the aquatic products to a stirring mixer by a screw conveyer; 2) placing the aquatic product fresh-keeping agent in a storage bin, adding the fresh-keeping agent into the stirring mixer by a constant weight feeder; 3) fully mixing the aquatic products and the fresh-keeping agent in the stirring mixer, then conveying the aquatic products and the fresh-keeping agent into an automatic packaging unit for packaging, and freezing and preserving. The method applies a chemical preservation and freezing preservation coupled technique, not only can effectively keep freshness, prevent corrosion and retain moisture, but also can restrain growth and propagation of bacteria in the aquatic products.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of aquatic products, in particular to a product fresh-keeping agent and a fresh-keeping method thereof. Background technique [0002] my country has a vast territory, abundant resources and a wide variety of aquatic products. In recent years, with the continuous development of the aquaculture industry, my country's annual output of aquatic products has continued to remain above 50 million tons, ranking first in the world for 15 consecutive years. Aquatic products (especially fish and shellfish) occupy an important position in the food structure, and their low-fat, low-calorie, and high-protein characteristics are indispensable elements in a reasonable dietary structure, and are favored by consumers. With the continuous improvement of people's living standards, the consumption of aquatic products is increasing day by day, and the requirements for its freshness are getting higher and higher. ...
