Abstract

The selenium-enriched broccoli freeze-dried instant ultrafine powder is prepared from the following components in parts by weight: 50 to 55 parts of selenium-enriched broccoli, 0.3 to 0.5 part of a sweetening agent and 0.01 to 0.03 part of a color fixative. The selenium-enriched broccoli freeze-dried instant ultrafine powder prepared by the method can be brewed or cooked with other things, and is extremely convenient to eat. And the ultrafine powder is rapidly dehydrated by adopting a freeze-drying technology in the preparation process, so that the nutritional ingredients of the selenium-enriched broccoli cannot be damaged, and the ultrafine powder is relatively healthy to eat. In the preparation process, multiple crushing and grinding treatments are carried out, so that the minimum particle size of the powder is ensured, and the powder is convenient to dissolve. Impurities in the broccoli powder are adsorbed through the adsorbent, so that the purity and the eating taste of the broccoli powder are guaranteed. A sweetening agent and a color fixative are added into the treated pulp, so that on one hand, the color of the favorite flowers is protected, oxidation is avoided, and on the other hand, the taste of the superfine powder can be improved, and the eating enjoyment is increased.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a freeze-dried instant superfine powder of selenium-enriched broccoli and a processing method thereof. Background technique [0002] Selenium is an indispensable nutrient and trace element for the human body. It has the functions of anti-oxidation, anti-aging, anti-cancer, anti-tumor, anti-radiation, prevention of cardiovascular and cerebrovascular diseases, etc. It enjoys the reputation of "fire of life". [0003] Selenium-enriched broccoli is a preferred ingredient for selenium supplementation, but broccoli needs to be cooked before it can be eaten. The preparation of selenium-enriched broccoli superfine powder from selenium broccoli is an important method to solve the inconvenience and low absorption rate of selenium-enriched broccoli. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a selenium-enriched broccoli freeze-dried insta...
