Sterilization of Teas and Spices

Tea and spices imported from tropical regions are shipped in bales, which very often contain pests, insects, fungi, and bacteria that must be destroyed before further processing can occur. This is done by placing the bales in vacuum containers and extracting the air. The bales are then injected with steam or a sterilized gas. This process helps to condition and sterilize the product, as well as add the proper humidity.
