Trehalose powder is formed by the condensation of two glucose molecules through hemiacetal hydroxyl groups and is a non-reducing disaccharide. Its sweetness is about half that of sucrose and can be broken down into glucose in the intestine, but its glycemic index is low. It exists in molds, algae, dry yeast, ergot, etc. and can also be synthesized. Studies have shown that the trehalose content of plants themselves is extremely low. As a natural sugar, trehalose can form a special protective film on the cell surface to protect its internal structure in harsh environments such as high temperature, high cold, and dryness.

What does trehalose do for skin?

1. Moisturizing and emollient
The trehalose molecule contains multiple hydroxyl polar groups, which can form hydrogen bonds with water molecules in the surrounding environment to firmly lock in moisture and play the role of water absorption and moisturizing.
2. Trehalose can maintain cell integrity well.
Trehalose can form a protective film with other cell matrices to reduce water evaporation on the skin surface, thus playing an emollient role.
Experiments show that adding 0.25% to 1% trehalose can significantly improve the survival rate of dehydrated epidermal cells.
3. In the processing of fruits, vegetables, meat and dairy products, trehalose can play a role in preservation and preservation.
4. Used in candies, chocolates, chewing gum and beverages, it can not only adjust the sweetness, but also prevent dental caries.

5. Trehalose is more widely used in biomedicine. For example, after adding trehalose to bioactive substances such as vaccines, antibodies, and recombinant albumin, they can be made into powders, which do not need to be refrigerated and can be restored to activity by dissolving in water when used.

6. In the agricultural field, trehalose can increase the survival rate of crop seeds and seedlings in harsh environments.

Trehalose powder

In 2000 and 2001, the United States and Europe approved trehalose powder as a food additive. It is used in cosmetics, food, health products, medicine, molecular biology and other fields.
