8 Neotame W. Wayne Stargel, Dale A. Mayhew, C. Phil Comer, Sue E. Andress, and Harriett H. Butchko The NutraSweet Company, Mount Prospect, Illinois I. INTRODUCTION Neotame (N-[N-(3,3-dimethylbutyl)-l-α-aspartyl]-l-phenylalanine 1-methyl ester) is a new high-intensity sweetener and flavor enhancer that is currently undergoing international regulatory consideration. Neotame is 7000 to 13,000 times sweeter than sucrose. It is derived from and is structurally similar to aspartame but is 30 to 60 times sweeter than aspartame, depending on the sweetness required in various food or beverage matrices. This zero-calorie sweetener has a clean sweet taste with no undesirable taste characteristics; neotame is functional and stable in a wide array of beverages and foods and should require no special labeling for phenylketonuria. Neotame resulted from a long-term research program designed to discover high-intensity sweeteners with optimized performance characteristics. French scientists Claude Nofre and Jean-Marie Tinti invented neotame from a simple N-alkylation of aspartame (1, 2). The NutraSweet Company holds the rights to a wide range of patents related to neotame. II. PHYSICAL CHARACTERISTICS AND CHEMISTRY A. Structure and Synthesis Neotame is manufactured from aspartame and 3,3-dimethylbutyraldehyde via reductive alkylation followed by purification, drying, and milling. The N-alkyl component of neotame, 3,3-dimethylbutanoic acid, occurs naturally in goat 129

Dry Stability Dry bulk chemical stability of neotame has been demonstrated for up to 4 years in studies that are continuing for a total of 5 years. Dry neotame is extremely stable, with the major degradation product being de-esterified neotame; deesterified neotame is formed at extremely low levels by the simple hydrolysis of the methyl ester group from neotame. De-esterified neotame is also the major aqueous degradant product and the major in vivo metabolite of neotame. More strenuous conditions involving higher temperatures and humidity result in the formation of increased amounts of de-esterified neotame without significant amounts of other degradation products; thus, neotame maintains an excellent material balance even under adverse conditions. Fluorescent lighting and polyethylene packaging have no effect on the stability of neotame. Stability studies have confirmed that products containing dextrose, maltodextrin, and neotame are stable when stored for extended periods of time at relevant storage conditions of ambient temperature and humidity. C. Stability in Food Applications Neotame is stable under conditions of intended use as a sweetener across a wide range of food and beverage applications. Neotame’s stability has been assessed
