protection against the tide
There are many ways to prevent moisture, such as a large number of medicinal materials, which can be kept in sealed boxes; If the amount is small and the medicinal materials are general, they can be stored in the refrigerator; However, if it is more expensive medicinal materials, such as Cordyceps, velvet antler and so on. , can be packed in a sealed bag, or wrapped in moisture-proof paper and placed at the bottom of the rice jar (the method is simple but practical).
If it is found that the medicinal materials have been affected with damp, they should be dried as soon as possible, or baked in a clean pot to remove water. Precious medicinal materials can be laid flat, covered with moisture-proof paper or clean tissue paper, irradiated with high wattage incandescent lamp to remove water, and then preserved according to the above preservation method.
mould proof
There are a large number of mold spores in the air, and the medicinal materials have high nutritional content and certain moisture. At a proper temperature, spores scattered on the surface of medicinal materials will absorb nutrients of medicinal materials, germinate hyphae and secrete enzymes, which will further destroy medicinal materials.
Under normal circumstances, medicinal materials can do a good job of moisture-proof, and basically will not be moldy.
If it is found that the medicinal materials are mildewed, the hyphae should be removed first. Usually use a soft brush or rag dipped in boiling water to wipe, and the medicinal materials that can be wetted with water can also be washed directly with water. If it is inconvenient to brush, it can be mixed with rice bran to knock off the hyphae, and then treated by moisture removal, but the time should be extended to effectively eliminate spores on the surface of medicinal materials.
Insect prevention
The main reason of moth-eaten is that the original eggs of medicinal materials can hatch when the temperature reaches a certain level. Some moth-eaten insects can secrete enzymes to decompose the internal substances of medicinal materials without water, so as to obtain the water needed for growth and at the same time cause the deterioration of medicinal materials.
The key to pest control is the treatment before preservation. High-temperature baking and frying can effectively kill eggs, but it is also an effective method to store medicinal materials that cannot be fried in the refrigerator.
When it is found that the medicinal materials have been eaten by insects, under normal circumstances, the internal damage of the medicinal materials has been serious, and it is recommended not to eat them again. If it is found that the broken medicinal materials are not seriously moth-eaten, they should be used as soon as possible after deinsectization, because moth-eaten will happen again after preservation.
