Background
The ginseng soup is a traditional soup with the main raw material of ginseng and the health-care effects of nourishing and building body, regulating immunity, improving physical strength and the like. The preparation method generally comprises selecting high-quality Ginseng radix, removing impurities, slicing, adding Ginseng radix slice and appropriate amount of water, stewing with slow fire for 3-4 hr to extract effective components such as ginsenoside and amino acid. In the stewing process, the heating time is controlled at a low temperature state, so that the nutritional ingredients in the ginseng are prevented from being damaged by the excessive temperature. Finally, filtering the residue to obtain concentrated soup, and adding appropriate amount of flavoring agent such as fructus Lycii and fructus Jujubae according to personal taste to further enhance taste and nutritive value. The radix scrophulariae decoction is suitable for long-term drinking due to its mild nourishing effect, and has remarkable health care effect especially for people with weak constitution and low immunity.
In the prior art, the radix ginseng alone soup and the preparation method thereof have the following defects that the nutrition components are lost, and the effective components in part of ginseng, such as ginsenoside, amino acid and the like, are possibly damaged or lost due to long-time heating at high temperature in the traditional stewing process, so that the health care effect of the soup is reduced. Especially, the long-time boiling is easy to cause a great deal of water-soluble components in the ginseng to be lost, the quality of products is affected, the extraction efficiency is low, the efficiency of extracting the effective components of the ginseng by the traditional stewing method is low, the extraction time is long, the energy consumption is high, and the preparation process is complicated. The concentration and quality of the extracting solution are difficult to control, so that the quality of each batch of products is unstable, and the taste is poor, wherein the traditional ginseng soup is bitter and astringent, and the taste of ginseng is heavy and is not easy to be accepted by masses. Although wolfberry fruit, red date and other seasonings can be added, the taste cannot be thoroughly improved, and especially for some consumers with relatively sensitive bitter taste, the drinking experience is poor, the quality guarantee period is short, and the traditional radix ginseng alone soup is easy to be polluted by bacteria or fungi due to no effective fresh-keeping treatment, so that the quality guarantee period of the product is short, and the storage condition requirement is high. The product is easy to deteriorate, especially in a high-temperature or humid environment, has complicated production process and high cost, the traditional stewing and boiling process needs long-time manual operation in the existing preparation method, has higher requirements on heat, temperature and the like, has complicated production process, long working time and low production efficiency, causes higher production cost and is difficult to realize large-scale industrialized production, and is difficult to absorb, and the traditional stewing and boiling process can extract effective components of the ginseng, but the components possibly exist in a macromolecular form, so that the human body has lower absorption and utilization efficiency and cannot achieve the optimal health care effect.
Therefore, we propose a novel radix ginseng alone soup and a preparation method thereof.

The ginseng is selected by first selecting ginseng of 4 to 6 years old and excellent quality. Ensuring that the ginseng has no mildew and pollution and the root is complete. Cleaning surface soil and impurities with clear water, and slicing Ginseng radix to facilitate extraction.
Selecting and treating auxiliary materials, namely selecting fresh Chinese wolfberry and red dates, removing impurities on the Chinese wolfberry, and cutting the red dates into slices. All auxiliary materials are cleaned, so that the sanitation standard is ensured.
2. Low temperature extraction
Placing sliced Ginseng radix, fructus Lycii and fructus Jujubae together into an extraction container, adding appropriate amount of water (about 10 times of Ginseng radix weight), and ensuring water content to cover all raw materials.
The low-temperature extraction technology is adopted, the extraction temperature is set to be 50 ℃, and the soaking time is set to be 4 hours. The extraction is carried out at this temperature, so that the effective components (such as ginsenoside, amino acid, etc.) in Ginseng radix can be retained to the maximum extent, and the destruction of beneficial components therein at high temperature can be avoided.
The extraction process adopts a continuous circulation soaking mode, and stirring is carried out once per hour so as to ensure the uniformity of the extracting solution.
