The storage mode of traditional Chinese medicine in modern medium and large Chinese medicine factories. Is there an alternative to sulfur fumigation?

Sulfur fumigation is mainly used to preserve and enhance color and prevent mildew and moth-eaten, such as yam, honeysuckle, Fritillaria cirrhosa, kudzuvine root, etc., and now it is not necessary to smoke with sulfur. The pharmaceutical factory will have a lot of stocks, but the color is not a problem, and the main thing is to prevent insects. If the warehouse is closed, it can be fumigated with trinitromethane for 2 days and nights before it is put into storage. Aluminum phosphide can also be used, and modified atmosphere maintenance, nitrogen or carbon dioxide can also be used.
