Trehalose is a naturally occurring non-reducing disaccharide, composed of two glucose molecules. It is widely found in plants, fungi, bacteria, and invertebrates. Renowned for its exceptional ability to stabilize proteins and protect cellular structures against damage from drying, freezing, and heat, trehalose is a highly valued ingredient in the food, pharmaceutical, and cosmetic industries. Its mild sweetness, about 45% that of sucrose, and clean taste profile make it an excellent sugar alternative. Trehalose is also known for its high glass transition temperature and low hygroscopicity.

1.Food Industry: Trehalose used as a sweetener, texture modifier, and shelf-life extender in beverages, confectionery, baked goods, and seafood. It effectively prevents starch retrogradation, protein denaturation, and fat oxidation.
2.Pharmaceuticals: Trehalose serves as a protective excipient in lyophilized (freeze-dried) injectables, vaccines, and diagnostic kits to protect bioactive ingredients from stress during drying and storage.
3.Cosmetics & Personal Care: Trehalose acts as a highly effective moisturizer and humectant in skincare products like creams, lotions, and serums. It protects skin cells from dehydration and environmental stress.
4.Biotechnology: Trehalose used as a stabilizer for enzymes, antibodies, and other labile biomolecules during research, development, and storage.
5.Agriculture: Trehalose applied in seed coatings and biopesticides to enhance resistance to drought and heat stress.
Trehalose is generally recognized as safe (GRAS) by the FDA and other international regulatory bodies. It is non-toxic, non-irritating, and well-tolerated by the human body. It is a naturally occurring sugar and is considered vegan.
Store in a cool, dry, and well-ventilated area.
Keep the container tightly closed to protect from moisture.
Avoid contact with strong oxidizing agents.
Trehalose is typically supplied in 25 kg multi-layer paper bags with polyethylene inner liner.
