Description

D-(-)-Fructose is a high-purity, naturally occurring ketohexose sugar, also known as levulose. This monosaccharide is a critical raw material and functional ingredient valued for its high sweetness and unique metabolic properties. It is essential for manufacturers in the food, pharmaceutical, and biotechnology industries seeking natural sweeteners, excipients, or fermentation substrates.

Application

• Food & Beverage Industry: Used as a natural sweetener in low-calorie and diabetic foods, beverages, dairy products, and baked goods due to its high relative sweetness.
• Pharmaceutical Formulations: Serves as an excipient in tablet formulations, syrups, and intravenous solutions, and as a starting material for chemical synthesis.
• Biotechnology & Fermentation: Acts as a preferred carbon source in microbial fermentation processes for the production of organic acids, enzymes, and biofuels.
• Nutritional & Dietary Supplements: Incorporated into sports nutrition and clinical nutrition products for its specific metabolic pathway.
• Chemical Synthesis: A key chiral building block for the synthesis of fine chemicals, specialty sweeteners, and pharmaceutical intermediates.
• Cosmetics & Personal Care: Functions as a humectant and skin-conditioning agent in lotions and creams.
