    摘要： An encapsulated flavorant or artificial sweetener for use with smokeless tobacco and related products. The encapsulated flavorant or artificial sweetener comprises a core encapsulated with a lipid-based coating that provides stability when in contact with tobacco, yet releases flavor over time when the product is used. The core comprises a carrier, such as silica, tobacco, beet fiber, citrus fiber, artificial sweetener, or the like, coated or loaded with a flavorant. Flavor loading may be in the range of approximately 10% to 60%, by weight. Flavorants include, but are not limited to, methyl salicylate (oil of wintergreen), cinnamon (e.g., cinnamon oil), peppermint (e.g., peppermint oil), and spearmint (oil of spearmint).
