Fresh-keeping method for rhizoma gastrodiae

Abstract

The invention relates to the technical field of biochemistry, in particular to a method for keeping the rhizoma gastrodiae fresh through biochemistry. The technological process comprises the following steps: cleaning fresh rhizoma gastrodiae; placing the rhizoma gastrodiae into water to boil for softening the rhizoma gastrodiae after the rhizoma gastrodiae is sliced and formed; boiling the rhizoma gastrodiae in the boiling water solution for about 2 minutes; taking out the rhizoma gastrodiae to soak and cool by cold water; taking out the rhizoma gastrodiae to place into a container containing matched liquid for being stored; sealing a cover; pasting a label; packing the rhizoma gastrodiae; and storing the rhizoma gastrodiae into a warehouse. The matched liquid is prepared from 80 to 120 g of citric acid, 10 to 30 g of sodium dehydroacetate, 80 to 120 kg of water and 20 to 35 g of sodium isoascorbate. The invention maintains the nutrition of the original rhizoma gastrodiae, and eliminates the harsh taste of the rhizoma gastrodiae per se, in addition, the processing is convenient, and the rhizoma gastrodiae is safe to eat.

Description

technical field [0001] The invention relates to the technical field of biochemistry, in particular to a method for preserving gastrodia elata through biochemistry. Background technique [0002] Gastrodia elata is a traditional advantageous industry in my country, and has always been sold as dry products. Fresh gastrodia elata is only available in a short period of time during the annual harvest season. With the development of science and technology and the demand for health care, fresh gastrodia elata has become more and more popular in consumption There are huge potential markets for fresh Gastrodia elata both at home and abroad. The existing methods and existing problems of gastrodia elata preservation are as follows: 1. Soaking in wine, fresh gastrodia elata is soaked in white wine, and only a small part of the active ingredients can be dissolved in wine It can be used, and the remaining active ingredients are wasted after fibrosis; 2. Soak in preservatives, soak in sorbic ...

Problems solved by technology

[0002] Gastrodia elata is a traditional advantageous industry in my country, and has always been sold as dry products. Fresh gastrodia elata is only available in a short period of time during the annual harvest season. With the development of technology and the demand for health care, fresh gastrodia elata has become more and more popular in consumption. There are huge potential markets for fresh Gastrodia elata both at home and abroad. The existing methods of gastrodia elata preservation and existing problems include: 1. Wine soaking. Fresh gastrodia elata is soaked in white wine, and only a small part of the active ingredients can be dissolved in wine. It can be used, and the remaining active ingredients are wasted after fibrosis; 2. Soak in preservatives, soak in sorbic acid and other preservative solutions, if the preservative dose is small, it cannot be stored for a long time. Imported fresh Gastrodia elata with antiseptic dose

3. When making canned food, high temperature changes the appearance, shape and color of fresh gastrodia elata, and soaking in sugar water makes fresh gastrodia elata lack characteristics

Adopt environmentally friendly and advanced new methods to solve the problems of changing quality, damaging components, and short fresh-keeping time that are not conducive to environmental protection and health in existing fresh-keeping Gastrodia elata
