Abstract: A method of producing a more intense flavorant. Trans-4,5-epoxy-(E)-2-decenal is enriched to contain at least 90% of the (−) isomer and is added to a product in an amount sufficient to flavor the product. The product may be a foodstuff, such as a food or beverage. Addition of the substantially pure (−) isomeric form of trans-4,5-epoxy-(E)-2-decenal achieves enhanced product taste and/or aroma, and provides increased economy and efficiency in its production.

Abstract: A squeeze dispenser for dispensing viscous liquid products such as pastes, jells and lotions. The dispenser includes a hollow housing, a pump mechanism in the form of a flexible hollow squeeze member attached along one side of the housing, and a product cartridge which is insertable into and removable from the housing. A substantially air tight seal is created between the product cartridge and the housing such that the interior of the housing forms a pressure chamber. A lower end of the product cartridge takes the form of a flexible plastic bag which holds the product. Two one-way valves are incorporated into the dispenser. One of these valves allows one-way flow of air from atmosphere into the flexible hollow squeeze member while the other of these check valves allows one way flow of air from the flexible hollow squeeze member into the pressure chamber of the housing.
