Abstract

The invention discloses a method for preserving freshness and color of cattail cabbage. It specifically includes the following steps: (1) soaking the fresh cattail in low-temperature ozone water for a period of time; (2) removing the cattail obtained in the above steps and then putting it into a mixed solution of edible salt solution and edible calcium chloride at a certain temperature Soak for a period of time, take it out, and then place it in a sterile environment to drain; (3) treat the cattail catkins drained in step (2) with short-wave ultraviolet rays, and seal the package; (4) pack the cattail catkins obtained in step (3) The vegetables are stored in a low temperature environment. The crisp and fresh preservation method of the present invention does not form frozen bodies, produce ice crystals, or damage cell walls when frozen aquatic vegetables are preserved; therefore, the liquid juice does not lose and can be recovered after rehydration; the color will not change after 12 months of frozen preservation , after thawing and desalting to cook the cattail, the taste is crisp and tender as before; the process is simple, the ingredients are safe, the economic cost is low, it is beneficial to the large-scale fresh-keeping production of the cattail, and the practical value is high.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preserving the freshness and color of cattail cabbage. Background technique [0002] Pucai is the most distinctive aquatic vegetable in Huai'an. It is white, fresh, fragrant, crisp and tender. It is one of the important ingredients of Huaiyang cuisine. Due to the season, it is not possible to use similar fresh cattail vegetables in winter, with good color, aroma, crispness and reasonable price, which brings a little regret to the dining table. In the past, cold storage, freezing, and quick freezing could not solve the idiosyncratic problems of 15 days to 9 months or longer. Refrigerated freshly stored at 0-5°C for no more than 10 days, and terminal browning will also occur during this period. After direct freezing and thawing, it cannot be rehydrated, and the quality drops significantly. When cooked, it tastes like grass, without brittleness. Although quic...
