As a stabilizer and protective agent of bioactive substances, d-trehalose anhydrous is widely used in food, health care products, cosmetics, medicine, molecular biology and agriculture.
D-Trehalose anhydrous has a special protective effect on biomolecules, which can keep many organisms active under abnormal conditions, such as high temperature, dehydration and freezing. D-Trehalose anhydrous has a special protective effect on biomolecules, which can keep many organisms active under abnormal conditions, such as high temperature, dehydration and freezing. 3. The principle of trehalose long-term preservation of food is that it can form a special film at room temperature to seal the food, and at the same time precipitate mucus to bind and moisturize it, and kill the original bacteria and subsequent contaminated bacteria. D-Trehalose anhydrous has a certain inhibitory effect on the bacteria on the surface of venison, and with the increase of the concentration of D-Trehalose anhydrous solution, the bacteriostatic effect is enhanced, and the optimal antibacterial concentration is 5.5%, beyond which the antibacterial effect decreases.

Structure: Unique 1,1-glycosidic linkage (unlike sucrose’s α,β-1,2 bond) makes it non-reducing and stable.
Physical traits: White crystalline powder, odorless, with a mild sweet taste (about 45% sweetness of sucrose).
Stability: Resists heat, acid, and hydrolysis under normal conditions; stable over a wide pH range (3–10).
Solubility: Highly soluble in water, slightly soluble in ethanol, insoluble in ether and other non-polar solvents.
Food industry: Used as a sweetener, humectant, and cryoprotectant to preserve the texture and flavor of processed foods (e.g., baked goods, dairy, frozen foods).
Cosmetics: Acts as a moisturizer and skin protectant, helping to lock in moisture and maintain skin barrier function.
Biotechnology: Serves as a protectant for proteins, enzymes, and cells during freeze-drying or storage, due to its ability to form a protective glassy matrix.
Generally recognized as safe (GRAS) by regulatory bodies; no known toxicity at normal intake levels.
Suitable for most populations, including diabetics (low glycemic index, minimal impact on blood sugar).
