Fresh-keeping technology for Chinese toon sprouts

Abstract

The invention relates to the technical field of vegetable refreshment and specifically relates to a fresh-keeping technology for Chinese toon sprouts. The fresh-keeping technology includes that Chinese toons growing in natural environment are cut from the clear and bright period to the grain rain period, and the length of the sprouts is controlled between 12cm and 18cm; loading is performed, leaves are prevented from being rubbed and dropped off, the Chinese toons are rapidly transferred to destinations, and solarization and rain are prohibited; the Chinese toons are washed by running water, water is heated to the temperature of 100DEG C, sodium chloride is added into the water, the Chinese toon sprouts are added into the mixed water and scalded for 8 seconds, and then the Chinese toon sprouts are fished out; the Chinese toon sprouts are placed in cold water at the temperature of 5 DEG C and subjected to thorough cooling, and then the Chinese toon sprouts are fished out and the water is drained away; and the Chinese toon sprouts are bundled to small bunches, a fluorite antistaling agent containing garlic essential oil is sprayed, the Chinese toon spouts are dried and placed at the temperature between 25 DEG C below zero and 30 DEG C below zero for freezing, the frozen Chinese toon sprouts are placed into a film bag, a bag opening is tightly bundled, and the film bag is placed into a constant temperature environment at the temperature of 1 DEG C below zero and 0 DEG C for refrigeration. The fresh-keeping technology has the advantages that the operation process is convenient, fast and safe, the storage time is long, the color is beautiful, the taste are delicious, the unique flavor of the Chinese toons is completely maintained, and the Chinese toons with excellent quality and reasonable price can be eaten at any time.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of vegetables, in particular to a fresh-keeping technology of Chinese toon buds. Background technique [0002] my country is the hometown of Chinese toon, and it is the only country where Chinese toon is eaten as a vegetable. The survival rate of Chinese toon is extremely high, whether it is in a mountainous area with poor soil or in a small farmyard. People eat it. It is not only nutritious, but also contains a lot of nutrients such as protein, calcium, iron, phosphorus, vitamins, carotene, etc., and has high medicinal value. . It is a pity that its picking and eating period is too short, only about one month, and Chinese toon is very perishable after the best feeding time, the dietary fiber contained in it will age, the stems and leaves will become woody, and its nutritional value will also deteriorate. Gradually reduced, in terms of processing technology of Chinese toon, it is mainly stor...
