Abstract

The invention provides a ginseng extraction process and application of a ginseng extract in food. The ginseng extraction process comprises the following steps: taking 5-6 years old ginseng, drying inthe air after cleaning, and then covering the dried ginseng with tin foil paper, sending into an oven and baking for 3-10min; taking out and then slicing, firstly adding an ethanol solution, wherein the adding amount of the ethanol solution is 3-4 times the mass of the ginseng, soaking for 10-12h under the condition of heating, and then adding the ethanol solution, wherein the adding amount of theethanol solution is 3-4 times the mass of the ginseng; carrying out heating reflux extraction for 2-3 times, wherein each time of reflux extraction lasts for 2-3h; merging extract, and recovering ethanol to obtain an intermediate; carrying out silica-gel column chromatography on the intermediate, separating and purifying to obtain the ginseng extract. The ginseng extraction process effectively increases the extraction rate of ginsenoside by means of reasonable technology improvement; furthermore, the purity of the ginseng extract can reach 97.5 or above; when being used for food preparation,the ginseng extract effectively improves the comprehensive health care performance of the food.

Description

technical field [0001] The invention relates to the technical field of ginseng extraction and application, in particular to a ginseng extraction process and the application of its extract in food. Background technique [0002] Ginseng is the dry root of the Araliaceae plant ginseng, which is mainly produced in Changbai Mountains, Jilin, Liaoning, Heilongjiang, Hebei, Shanxi and other places in my country. It is a traditional and precious Chinese medicinal material in China. The effects of spleen and lung, promoting body fluid, and calming the nerves. Ginseng has dual effects of calming and exciting on the regulation of the nervous system. Traditional Chinese medicine has used ginseng for thousands of years. At present, there are dozens of Chinese patent medicines that use ginseng as the main medicine in clinical practice. . [0003] Modern studies have shown that more than 40 kinds of ginsenoside monomers have been isolated and identified in ginseng. Ginsenoside is the main a...
