Abstract

The invention discloses a method for preparing radish leaf dietary fiber powder, and belongs to the technical field of agricultural product processing. The method includes the following steps: immersing radish leaves in 1% baking soda and 3% salt solution, then drying, and then pulverizing the dried radish leaves, mixing the pulverized radish leaves with plant protease for enzymolysis, then inactivating the enzyme at high temperature to obtain a precipitate, washing the precipitate with 70% ethanol to remove soluble sugar, and finally further drying and sieving solid matter obtained after separating slurry with a jet mill to obtain the radish leaf dietary fiber powder. The dietary fiber powder has faint scent of the radish leaves, retains nutritional ingredients of the radish leaves to themaximum extent, has a health-care effect, and can further be used as an additive for leisure foods. The preparation method is simple and pollution-free, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a preparation method of radish leaf ultrafine dietary fiber powder. Background technique [0002] White radish leaves are a food source with high nutritional value. Studies have shown that it is rich in a large amount of cellulose, which can promote human gastrointestinal motility and promote the excretion of waste in the body. Regular consumption can have a laxative effect; secondly, radish leaves also contain a variety of vitamins and minerals, especially It contains vitamin C and vitamin B, which can promote skin cell metabolism and regeneration, and can delay skin aging. [0003] The annual output of radish in my country is huge. In most cases, people only pay attention to the consumption of radish roots and ignore the value of radish leaves. Usually radish leaves are either discarded in the field, causing pollution to the environment, or they are so...
