2. Brush fresh ginseng
Brush fresh ginseng with a soft-bristled toothbrush (be careful to use a soft-bristled toothbrush, which may damage ginseng skin) to make it clean.
3. Sun-drying ginseng
Wash the fresh ginseng in the sun for 1-2 days, turn it over 2-3 times a day, and pay attention to ventilation. In this way, most of the water in the ginseng roots is dried.
in the traditional processing step of sun drying, there is another step after sun drying, that is, the sun dried ginseng is put into a drying room for drying ginseng, and the temperature is controlled at 3 ~ 4℃ for drying, and the moisture is discharged every 1 ~ 2min. When the water content of ginseng roots is 13% or less, the water content requirement of commercial sun-dried ginseng can be met.
However, ordinary families don't have special tools for baking ginseng, so the drying time of ginseng can be appropriately increased to reduce the water content of raw ginseng. Pay attention to the sun ginseng temperature, don't insolate, if the sun is too big, you can use gauze to cover it a little. Sun until ginseng is dry and hard inside and outside.
steps of ginseng preservation method:
① firstly, dry the bought northeast ginseng in the sun to remove moisture, and if the sun is too strong, cover it with white paper;
② Then divide the Northeast Ginseng into equal parts, each of which is divided into half a month's dosage, and pack it in plastic bags.
③ Seal the plastic bags filled with Northeast Ginseng, and then put them in sealed cans with desiccant.
④ Finally, put the sealed cans in the refrigerator for low-temperature refrigeration, and take out a small bag every time. It is not necessary to put them in sealed cans after use, but they can be directly put into the refrigerator for refrigeration.
In this way, it can effectively prevent Northeast Ginseng from getting damp and mildew, and secondly, it can also avoid the food in the refrigerator from smelling with Northeast Ginseng or losing the taste of Northeast Ginseng. The ginseng can be preserved for a long time without deterioration, and the curative effect can also be guaranteed.
2. drying method: lime silica gel, calcium chloride and charcoal are often used as moisture absorbent. Putting lime as moisture absorbent into the bottom of the container, putting ginseng on it and sealing it can keep the northeast ginseng dry, which has the functions of fast drying, mildew resistance and moth-proofing, but it has little effect on preventing ginseng from flooding and odor loss. As a moisture absorbent, silica gel is not as good as lime, but it can be used repeatedly after baking. A small amount of northeast ginseng should be stored with silica gel. Lime drying has the characteristics of economy, safety and convenience, and is the most commonly used desiccant. When lime is dispersed into powder, it must be replaced.
