Abstract
A substantially pure stabilized compound having Vitamin E activity is added to smokable or smokeless tobacco or non-tobacco products to achieve less irritation and antioxidant benefits. In a preferred embodiment, a substantially pure “dry” powdered ester analog of Vitamin E, such as Vitamin E acid succinate, Vitamin E acetate or d-alpha-tocopheryl polyethylene glycol succinate is mixed directly with the tobacco during the curing or manufacturing process. For cigarette applications, these Vitamin E compounds can also be inserted into a cigarette filter, holder and/or paper, either in powdered form or in microencapsulated form. Although not preferred, a common oily form of Vitamin E can be used in the present invention so long as it is stabilized and does not ruin the appearance and function of the tobacco or non-tobacco products.
