Abstract

The invention discloses a fresh-cut common cattail ageing rottenness retarding and storage time prolonging preservation method. The fresh-cut common cattail ageing rottenness retarding and storage time prolonging preservation method comprises the following steps of selecting, cleaning, cutting and washing fresh common cattail; soaking the fresh-cut common cattail in chlorine dioxide solution and then performing dewatering; then soaking the fresh-cut common cattail into coating solution, and then performing dewatering; wrapping and sealing the fresh-cut common cattail in preservative films forlow-temperature storage. According to the fresh-cut common cattail ageing rottenness retarding and storage time prolonging preservation method, the fresh-cut common cattail is soaked into the chlorinedioxide solution, so that activity of polyphenol oxidase and peroxidase can be inhibited, surface microorganisms of common cattail can be killed, and further the fresh-cut common cattail is less prone to rottenness; meanwhile, the fresh-cut common cattail is coated for isolation from air, so that the possibility of oxidization as well as rottenness of the fresh-cut common cattail can be reduced.Experiment results show that the fresh-cut common cattail ageing rottenness retarding and storage time prolonging preservation method is higher in preserving effects on the fresh-cut common cattail and effectively retards oxidation and rottenness of the fresh-cut common cattail.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable storage and preservation, in particular to a low-temperature preservation method for fresh-cut cattail cabbage with an antibacterial coating. Background technique [0002] Cattails, also known as cattails, cattails, cattails, cattail roots, grass buds, and ivory vegetables, belong to the family Typhaceae and are a unique traditional dish in Huai'an City, Jiangsu Province. Pucai mainly grows in swamps and freshwater lakes. It is eaten as a vegetable with the inner layer of the pseudostem enclosed by the leaf sheath or the young stems and branches crawling underground. It is not only rich in nutrition, but also has certain medicinal value. The tender stems of cattail cabbage contain nutrients such as protein, fat, carbohydrates, dietary fiber, calcium and phosphorus, as well as various vitamins and amino acids. Modern studies have shown that cattail catkins also have certain medicinal v...
