Problems solved by technology

This document uses a single raspberry as a raw material, which has a single nutrition, and the raspberry has high acidity, which affects the taste. In addition, the pre-cooling temperature of the method in this document is not enough, which is not good for the preservation of the original fruit shape and active substances, and the degree of crushing is not enough, which affects the absorption efficiency of the human body.
The raspberry freeze-dried and pulverized preparation adopts a pre-freezing temperature of minus 26°C to 30°C, and the analysis temperature is controlled between 50°C and 55°C. There is no low temperature protection during the crushing process, and the analysis temperature and crushing temperature are too high to ensure that the raspberry Retention of active substances, insufficient fragmentation

Abstract

The invention discloses freeze-dried compound berry superfine powder and a production method thereof. The freeze-dried compound berry superfine powder is produced from the following berries in percent by weight: 40-45 percent of raspberry, 25-30 percent of blueberry, 6-8 percent of mulberry, 10-14 percent of sea-buckthorn, 4-6 percent of medlar and 5-7 percent of Lonicera caerulea. The method comprises the following specific steps: weighing and cleaning the berries, and draining for standby; mixing the drained berries under the condition of normal pressure and the temperature of 80 DEG C below zero, freezing for 1-3 hours, and rapidly freezing the fruits; keeping the frozen mixed berries in an environment with the pressure of 50-100Pa for 3-4 hours, controlling additional heating, and returning the temperature to 0 DEG C within 4-5 hours; raising the temperature from 0 DEG C to 45 DEG C within 6-8 hours, wherein the pressure is kept to be 20-50Pa; grinding the berries into the granularity of 5000-10000 meshes at the temperature of 0 DEG C by adopting nitrogen protection; preparing the ground superfine powder into tablets. The berries are reasonably proportioned, so that a health care effect is achieved, the functional ingredients in the product are enriched, the taste characteristics of the product are improved, the product is fresh to drink, contributes to human body absorption and is conveniently prepared into the tablets, and the active substances are well kept.
