Problems solved by technology

In recent years, as people gradually pay more and more attention to health care of the body, the demand for wild food has increased year by year. However, acacia flowers are extremely difficult to store for a long time, and their freshness period is short During the period, it is easy to cause rot and become inedible; at present, the storage methods used by merchants are: first, vacuum packaging after drying; second, freezing after drying. The above two methods are simple and practical, but the The storage period is generally about 4-5 months at most, and the color and quality of itself cannot be guaranteed for a long time, and the mouthfeel of itself is poor after the storage period, and the nutritional value is also greatly reduced. Therefore, there is an urgent need for a A relatively complete processing method that can prolong the storage period

Abstract

A processing method capable of prolonging the storage period of acacia flowers and retaining their nutritional value. The processing steps are as follows: pick fresh acacia flowers, wash them, air-dry them, and then prepare auxiliary fresh-keeping liquid A and auxiliary fresh-keeping liquid containing dandelion soaking liquid and tea polyphenol liquid B. The air-dried acacia flowers are processed in sequence as follows: soak in auxiliary preservative solution A, take out and air-dry, soak in auxiliary preservative solution B, take out and dry; put the dried product into a vacuum preservation box , put the fresh-keeping box into the cold room for preservation, and the processing of the acacia flower is completed. In the present invention, through the processing steps of two slow air drying and one fast drying, and soaking in auxiliary fresh-keeping liquid during the air drying process, the processed product can achieve a storage period of about 12-15 months without reducing The nutritional value of the product.
