Abstract

The invention discloses a dried lily flower preservative as well as a preparation method and application of the dried lily flower preservative. According to the dried lily flower preservative, each 1000ml of dried lily flower preservative comprises 10-20 weight parts of calcium hypochlorite, 0.01-0.1 weight part of 6- benzyl amino adenine (6-BA) and plant extracts, wherein the plant extracts is 70% ethanol extracts including 15-36 weight parts of pomegranate bark, 10-28 weight parts of orange peel, and 10-25 parts of honeysuckle. The picked dried lily flower is smeared with a layer of 1.0-1.5% of chitosan after being processed by the preservative, and is preserved within the shelf life at the normal temperature of 20-22 DEG C. The output rate of the dried lily flower within 9-day shelf life at the normal temperature is above 85%, no browning phenomenon happens, and the content of vitamin C of the dried lily flower keep above 32.15mg / 100g. The freshness-keeping method disclosed by the invention is safe, rapid and convenient. The freshness-keeping method is safe, efficient and convenient, can maintain the quality of the dried lily flower, and meanwhile, the freshness-keeping method can delay the blooming of the dried lily flower, and reduce the rotting rate of the dried lily flower.
