Abstract: Compositions comprising the sweetener N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester sweetener (“neotame”), or L-aspartyl-L-phenylalanine sweetener (“aspartame”), and at least one divalent cation, trivalent cation or mixture thereof are disclosed. Divalent and trivalent cations enhance the stability of neotame and aspartame in edible compositions, including cola-type soft drinks and syrups.

Abstract: The use of N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester (neotame) as a sweetener in chewing gum compositions is disclosed. The chewing gums have been found to have a clean sweet taste profile with an extremely low level of sweetener usage. The use of neotame as a sweetener in chewing gum compositions also provides an extension of both sweetness and flavor as compared to that expected from the use of other sweetener ingredients.

Abstract: A novel amorphous N-[N-(3,3-dimethylbutyl)-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester compound is disclosed. Also disclosed are processes for preparing the compound. The novel compound has improved solubility and dissolution properties compared to the known monohydrate.

Abstract: A replacement centerfire bolt assembly for a rimfire rifle having a two-piece bolt with a detachable bolt head assembly and a method for modifying a bolt are disclosed. In accordance with the method, the bolt is first removed from the rifle, and then the rimfire bolt head assembly is removed from a remainder of the bolt. Next, a centerfire bolt head assembly is attached to the remainder of the bolt in place of the rimfire bolt head assembly. This centerfire bolt head assembly includes a bolt head having a central longitudinal axis, a cartridge end, a striker end, and an exterior size and configuration functionally identical to a size and configuration of a rimfire bolt head of the rimfire bolt head assembly. A bore is provided along the central longitudinal axis of the bolt head, with this bore including an enlarged recess adjacent the striker end. A one-piece centerfire firing pin is located in the bore of the bolt head, which firing pin is longer than the bore.
