Description

Trehalose is a non-reducing disaccharide sugar composed of two glucose molecules, renowned for its exceptional stabilizing and protective properties. Its unique ability to form a stable glassy matrix makes it a critical ingredient for preserving the structure and function of sensitive biological materials and active compounds. This high-purity sugar is essential for manufacturers in the pharmaceutical, biotechnology, food science, and cosmetics industries seeking to enhance product stability, shelf-life, and performance.

Application

• Pharmaceutical & Biologic Stabilizer: Protects proteins, vaccines, enzymes, and antibodies from denaturation during lyophilization (freeze-drying) and long-term storage.
• Cryoprotectant: Used in cell and tissue culture media to protect cells from damage during freezing and thawing cycles.
• Food & Beverage Ingredient: Functions as a mild sweetener, texture modifier, and shelf-life extender in baked goods, confectionery, and beverages, preventing starch retrogradation and protein denaturation.
• Cosmetics & Personal Care: Acts as a highly effective humectant and moisturizer in skincare formulations, helping to maintain skin hydration and protect active ingredients.
• Diagnostic Reagents: Stabilizes enzymes and other bioactive components in diagnostic kits and test strips to ensure consistent performance and accuracy.
• Agricultural & Seed Treatment: Applied as a protectant to improve the viability and longevity of seeds, beneficial microbes, and biopesticides.

Quality Control

Our Trehalose is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. It can be manufactured to meet various pharmacopeial standards, including USP-NF, EP, JP, and food-grade specifications like FCC. Every lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters, ensuring compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
