Description

L-Glucono-1,5-Lactone is a high-purity, naturally derived organic compound widely used as a versatile acidulant and chelating agent. Its controlled, non-volatile acid release profile makes it a critical functional ingredient for achieving precise pH control and texture modification. This product is essential for manufacturers in the food, pharmaceutical, and personal care industries seeking clean-label, multifunctional, and reliable chemical solutions.

Application

• Food Industry: As a slow-release acidulant in baked goods (baking powders), dairy products (tofu coagulant, cheese), meat processing, and beverage systems for controlled tartness and leavening.
• Pharmaceutical & Nutraceuticals: Used as an excipient in effervescent tablets and powders, and as a mineral carrier (e.g., calcium gluconate precursor) in dietary supplements.
• Personal Care & Cosmetics: Functions as a pH adjuster and mild exfoliant (AHA derivative) in skincare formulations such as cleansers, toners, and creams.
• Industrial Applications: Serves as a metal sequestrant in cleaning formulations, a retarder in cement, and a component in textile and leather processing.
• Biochemical Research: Utilized as a substrate or intermediate in enzymatic studies and microbial fermentation processes.

Quality Control

Our L-Glucono-1,5-Lactone is manufactured under a strict quality management system. It is produced to meet relevant standards for food (FCC), pharmaceutical (USP/EP), and industrial grades. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) documenting purity, physical characteristics, and safety parameters is provided with each shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent caking or hydrolysis due to moisture absorption.
