Abstract

The invention specially relates to instant fresh-ginger powder and a preparation method of the instant fresh-ginger powder. The preparation method comprises the following steps: using the fresh gingers as the raw material; and performing the following processes on fresh gingers: pre-treating, extracting, filtrating, concentrating, blending and drying, so that the instant fresh-ginger powder is prepared. With respect to the process of extracting, the pre-treated fresh-ginger powder is extracted in 75% edible alcohol for 15-40 hours, wherein the material-to-solution ratio is 1: (5-20); with respect to the process of filtrating, the extracted solution is filtrated by 6-10 layers of gauzes; with respect to the process of concentrating, the filtrate is concentrated by pressure reduction until the volume of the concentrated filtrate is one sixth to one thirteenth that of the original volume; with respect to the process of blending, the dextrin is mixed with the concentrated solution, wherein the dextrin-to-solution ratio is 1: (14-40); and with respect to the process of drying, the blended mixture is dried by spraying, wherein the wind-inlet temperature is 135-160 DEG C and the material-feeding volume is 10-30%. The processes of extracting and concentrating are adopted in the invention, so that the functional component content of the prepared fresh ginger is higher than that of the fresh ginger; thus, the instant fresh-ginger powder has relatively high pharmaceutical and healthcare functions. Moreover, the preparation technology is easy to operate and economical in cost; leftover bits and pieces of processed fresh gingers can be utilized in the preparation technology and the operation process fully satisfies food health and safety requirements.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to instant ginger powder and a preparation method thereof. Background technique [0002] Ginger (Zingiber officinale Roscoe) belongs to the rhizome of Zingiberaceae Zingiberaceae plant, which is a popular seasoning raw material, which can enhance appetite and promote digestion. In addition, ginger also has the effects of sweating and relieving the exterior, warming the middle and relieving vomiting, warming the lungs and relieving cough, and detoxifying drugs. It can be used for the treatment of exogenous cold, headache, phlegm, cough, stomach cold and vomiting. Therefore, no matter ginger is used as food or Chinese medicinal material, it is all very extensive. Ginger is dug in autumn, but fresh ginger is not resistant to high temperature or low temperature, so it is difficult to store for a long time, which makes the storage and perennial supply of fresh ginger difficult.
