Novel vacuum freezing production method for herba dendrobii

Abstract

The invention discloses a novel vacuum freezing production process for herba dendrobii, belongs to the technical field of food processing, and aims to provide a novel vacuum freezing production process. The novel vacuum freezing production process for the herba dendrobii is characterized in that a vacuum freeze-drying single-factor test and a three-factor three-level orthogonal test are carried out by taking pre-freezing time, vacuum drying time and raw material shape as influencing factors according to the physiological characteristics of the herba dendrobii, the moisture content of a dried product of the herba dendrobii is measured, and thus, optimal conditions of the vacuum freeze-drying production process of the herba dendrobii are obtained. Under the condition that nutritional ingredients and physiological activity of the herba dendrobii are maintained to a great extent, energy consumption is greatly reduced, the production cost is reduced, and industrialized production of the herba dendrobii in China is promoted to a high level.

Description

[0001] 1. Technical field [0002] The invention belongs to the field of food, and specifically refers to a new vacuum freezing production method of Dendrobium candidum pine. [0003] 2. Background technology [0004] Dendrobium officinale is rich in dendrobine and polysaccharides. It is a very valuable medicinal and edible Chinese herbal medicine in my country. It has the effects of clearing away heat and detoxification, nourishing yin and blood, promoting body fluid and stomach, increasing intelligence and calming the nerves. "Known as the first of the nine Chinese fairy grasses. [0005] There are usually two traditional processing methods of Dendrobium officinale: one is to cut the stems of fresh Dendrobium officinale into sections and dry them; Fengdou". All adopt the common drying method, and the cell wall of the finished product is hard after shrinking, and it needs to be fried for more than 2 hours to break the wall when eating, and a large amount of active ingredients...

AI Technical Summary

Problems solved by technology

This method also has the problems of long time and high energy consumption.

[0009] The present invention aims to solve the problems of high energy consumption and poor drying effect in the existing vacuum freezing production method of Dendrobium pine, and provides a new vacuum freezing production method of Dendrobium pine. The production method processes Dendrobium candidum and has low water content can best preserve the color, fragrance, taste, shape and active ingredients of Dendrobium officinale; after rehydration, it is closer to fresh products, avoids surface hardening of products, less nutrient loss, and long shelf life, etc.
