Trade East spices are manufactured using a unique cryogenic milling method. Liquid nitrogen is used to cool the product and the mill head while grinding. Spices are cooled to temperatures as low as -250° F.
Heat, light and moisture are three components that deteriorate spices. Cryogenic milling reduces the volatile oil (flavor components) loss compared to the ambient milling process. Ambient milling creates heat that inherently burns flavor, which is undesirable. The more volatile oils captured, the more potent the flavor and aroma.
An example of the visual and flavor-benefits of cryogenic milling can be found by cutting cumin.
