Fresh keeping method for shrimp meat

Abstract

The invention discloses a fresh keeping method for shrimp meat. The fresh keeping method disclosed by the invention solves the problem of poor actual fresh keeping effect existing in a fresh keeping method for the shrimp meat in the prior art. The fresh keeping method mainly comprises the following steps: (I) preprocessing shrimp meat; (II) preparing a composite film forming solution: (1) preparing a propolis aqueous extract, (2) preparing ginger filtrate, (3) preparing garlic filtrate, and (4) mixing the propolis aqueous extract, the ginger water and the garlic water so as to compound the composite film forming solution; (III) soaking the preprocessed shrimp meat into the composite film forming solution for film forming; and (IV) packaging the shrimp meat obtained in the step (III), and refrigerating the packaged shrimp meat. The fresh keeping method for the shrimp meat, disclosed by the invention, is simple in technology steps and high in maneuverability; the formula and the steps of the film forming solution are optimized, so that better texture characteristics of the shrimp meat can be maintained, the flavor and the mouth feel of the shrimp meat are effectively maintained, the losses of nutrient components and juice are reduced, the corruption of the shrimp meat is delayed, and the preservation period is prolonged.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping aquatic products, in particular to a fresh-keeping method for fresh shrimps. [0002] Background technique [0003] Shrimp meat is tender, delicious, high in protein, low in fat, contains a lot of trace elements and essential amino acids for the human body, and is an animal food with high nutritional value. Shrimp, as a processed form of shrimp, is popular because it does not contain shrimp shells and is more convenient to eat. [0004] At present, the traditional fresh-keeping methods for fresh-keeping shrimps are refrigeration or freezing preservation, but these two fresh-keeping methods all have the following deficiencies: cold storage, although the structure of fresh-keeping shrimps has not been destroyed, because the protease existing in its tissue still has relatively large activity, As a result, the fresh-keeping time is short, and the frozen fresh-keeping will destroy the tissue st...
