Abstract

The invention relates to the technical field of food fresh keeping and in particular relates to a squid fresh-keeping agent as well as a reparation method and a fresh-keeping method thereof. The squidfresh-keeping agent is prepared from the following components in parts by weight: 10 to 15 parts of radix polygonati officinalis polysaccharide extract, 3 to 6 parts of coral reef powder, 1 to 3 parts of phytic acid, 2 to 5 parts of tea polyphenols, 1 to 3 parts of protamine, 1 to 3 parts of sodium lactate and 180 to 200 parts of water. The squid fresh-keeping agent provided by the invention hasthe advantages of relatively good bacterium-inhibition and water-retention performance and long fresh-keeping time.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a squid preservation agent, a preparation method and a preservation method thereof. Background technique [0002] Squid, also known as calamari and squid, is the general name of the mollusk phylum cephalopods and squids. The body of the squid is divided into a head, a very short neck and a trunk. There are a pair of well-developed eyes on both sides of the head and arms and feet around the mouth. The carcass of squid accounts for about 50% of the body weight, the head and feet account for about 30% of the body weight, and the edible part is nearly 80%, which is about 20% higher than that of ordinary fish. It is a good raw material for aquatic product processing. Squid has the advantages of high protein, low fat, and low calorie. It is also rich in calcium, taurine, phosphorus, vitamin B1 and other nutrients necessary for the human body. It is a nutritious health food. ...
