Description

D-(+)-Glucono-1,5-Lactone is a naturally occurring organic compound that serves as a versatile acidulant and sequestrant in numerous industrial processes. Its controlled hydrolysis to gluconic acid provides a unique, non-volatile, and mild sourness, making it a critical ingredient for precise pH adjustment and flavor development. This high-purity chemical is essential for manufacturers in the food, pharmaceutical, and personal care industries seeking consistent quality and reliable performance in their formulations.

Application

• Food Industry: Primary use as a slow-release acidulant in baked goods (baking powders), dairy products (tofu coagulant, cheese), beverages, and meat processing to control acidity and texture.
• Pharmaceuticals: Used as an excipient in effervescent tablets and powders due to its non-hygroscopic nature in the dry state and controlled reaction with carbonates.
• Personal Care & Cosmetics: Acts as a pH adjuster and chelating agent in creams, lotions, and hair care products to stabilize formulations and enhance efficacy.
• Industrial Cleaning: Employed in alkaline detergent formulations and metal surface treatments for its superior sequestering power against calcium and other metal ions.
• Agriculture & Animal Feed: Serves as an acidifier in silage and animal feed to improve preservation and nutrient absorption.
