Abstract

The invention relates to the technical field of food processing, in particular to an oyster preservation method. The oyster preservation method comprises the following steps: (1) opening shells to take meat: opening shells of oysters to take meat, and cleaning the meat with clear water; (2) rinsing: rinsing the oyster meat obtained in the step (1) in rinsing liquid for 8-12 minutes; (3) ultrasonic treatment: performing ultrasonic treatment on the oyster meat obtained in the step (2); and (4) photodynamic sterilization: soaking the oyster meat obtained in the step (3) in a photosensitizer solution, then immediately taking out the oyster meat, and performing LED light source irradiation to complete the sterilization process. According to the oyster preservation method, the quality of the oyster meat can be effectively improved, so that the eating quality of the sea oyster meat is improved, meanwhile, the oysters can be effectively sterilized in a photodynamic sterilization mode, the shelf life of the oysters is obviously prolonged, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a fresh-keeping method for oysters. Background technique [0002] Oysters (ostreagigastnunb), commonly known as sea oysters, oysters, etc., belong to the mollusk phylum, bivalves, and pearl oysters. They are the largest cultured shellfish in the world and one of the important marine biological resources available to humans. type. Oysters are not only delicious and nutritious, but also have unique health care functions and medicinal value. They are a rare seafood with high nutritional value. Due to the self-pollution and terrestrial pollution of aquaculture and other reasons, the bacteria in the oyster body are relatively complex, and they are also easily spoiled. Therefore, sales of fresh oysters are limited to coastal provinces. How to effectively extend the shelf life of fresh oysters and expand the sales range of fresh oysters has become a topic of great concern to ...
