Description

TECHNICAL FIELD [0001] The present invention relates to a method of producing a red ginseng water extract having enhanced specific ginsenoside content,

The present invention relates to a method for preparing red ginseng water extract having improved quality by increasing the content of saponin by lowering the temperature in the first extraction by adding water to red ginseng and increasing the temperature by increasing the temperature in the second extraction, A water extract and a ginsenoside content in a red ginseng water extract.

In recent years, as the level of living and interest in health have increased, interest in ginseng has spread, and a variety of processed products corresponding to consumers' preferences have been developed along with the development of food processing technology, and the demand for products is rapidly increasing.

Ginseng is a perennial herbaceous herbaceous plant belonging to Panax ginseng (Araliaceae) in plant taxonomy and has long been used as an important medicinal herb in oriental medicine. Ginseng is generally classified as white ginseng and red ginseng according to the processing method. White ginseng is dried as it is, that is, unprocessed ginseng, that is, ginseng, which is mined in the field, and red ginseng is steamed and dried. And changes in the chemical structure. Especially, the saponin components such as ginsenosides Rg2, Rg3, Rhl, and Rh2, which are unique components of ginseng, which are not present in ginseng, are newly generated by the heat generated in the manufacturing process of red ginseng. It is known that there is growth inhibitory action, hypotensive action, brain cell protection and learning ability improving action, anti-thrombogenic action, antioxidant action, immune enhancement, blood glucose lowering, and so it can be expected to exert excellent pharmacological effect only for red ginseng. However, since red ginseng is dried and hardened, it is difficult to directly take it. Therefore, it is usually processed and distributed in the form of powder, slice, tablet, concentrate, pouch, etc., The consumption of the extract (pouch) is increasing. Therefore, the majority of Korean red ginseng processed products contain the red ginseng extract or are commercialized as such, and the red ginseng extract is most widely produced at the production site.

Generally, red ginseng extract is produced in the order of extraction process and filtration process in the order of production, but the process has not been established yet. Especially, in case of red ginseng extraction process, extraction method is different for each producer. Even when raw materials are used, there is a difference in the quality of the red ginseng extract produced. In addition, in the method of extracting red ginseng, the saponin content of the red ginseng extract varies depending on the extraction solvent and the setting temperature and time of extraction. In contrast, in the production field, .
