D(+)-Trehalose Dihydrate Uses
Baking Products:
Trehalose enhances baked goods by adjusting sweetness and aroma in items like cakes, biscuits, pastries, and fillings, without affecting shelf life. It reduces fat in cookies, creams, and icings, creating a pleasing texture in savory snacks while maintaining a balanced sweetness.
Candy:
It blends well with other sweeteners in candies, fruit juices, and herbal products, preserving the natural flavors while adjusting sweetness levels.
Medical and Biological Applications:
Trehalose acts as a protective agent for biomolecules in blood products, vaccines, antibodies, and more. It preserves biological materials like skin and organs during dry storage and transport by replacing lost water, maintaining hydration, and protecting cell membranes from damage.
Skincare:
In skincare, trehalose safeguards skin cells by maintaining membrane fluidity during dehydration, preventing damage through anti-fusion and leakage mechanisms.
