Storage mode of traditional Chinese medicine in modern large and medium-sized Chinese medicine factories. Is there a substitute for sulfur fumigation?

Sulfur fumigation is mainly used to preserve and enhance color and prevent mildew and moth-eaten, such as yam, honeysuckle, Fritillaria cirrhosa, pueraria lobata and so on. There is no need to smoke with sulfur now. The pharmaceutical factory will have a lot of stocks, but the color is not a problem, mainly to prevent insects. If the warehouse is closed, it can be fumigated with trinitromethane for 2 days and nights before storage. Aluminum phosphide, modified atmosphere, nitrogen or carbon dioxide can also be used.
