Aspartame Food Grade (E951)

Aspartame 

Aspartame is synthesized by chemically coupling aspartic acid and phenylalanine methyl ester, used as a high-intensity non-caloric sweetener (INS 951) that provides clean sucrose-like sweetness without bitter aftertaste or gastrointestinal effects, ideal for sugar-reduced and diabetic formulations. In the food industry, it delivers sugar-like temporal profile and synergizes with bulking agents like maltodextrin for optimal mouthfeel in beverages, confections, and tabletop applications.

Food Industry Applications

• Beverages: Primary sweetener in diet sodas, zero-calorie energy drinks, iced teas, flavored waters, and powdered drink mixes creating full sugar sweetness at 0.01-0.02% usage; stable in neutral pH carbonated systems; masks acidity without metallic notes.

• Confectionery: Sweetens sugar-free gums, hard candies, chocolates, and mints providing rapid sweetness onset and prolonged flavor release; synergizes with acesulfame-K for heat stability during boiling; prevents crystallization in syrup centers.

• ​Dairy products: Flavors low-fat yogurts, milk puddings, frozen desserts, and drinkable yogurts maintaining creaminess without lactose contribution; post-dissolution stability prevents flavor drift during refrigerated storage.

• ​Bakery products: Provides sweetness in no-bake cheesecakes, reduced-sugar cookies, and cake frostings added post-baking to preserve phenylalanine ester; bulking combinations prevent collapse during mixing; enhances fruit flavors in fillings.

• ​Snack foods and cereals: Sweetens granola bars, breakfast cereals, nutrition bars, and extruded snacks delivering clean sweetness synergy with high-intensity blends; coating stability prevents migration during packaging.

​Other Industry Applications

In cosmetics, sweetens oral care rinses and toothpastes; in animal feed, flavors palatability enhancers for pet foods; in tobacco products, sweetens chewing gums and nicotine lozenges; in agriculture, masks bitterness in pesticide baits.
