Trehalose, also known as trehalose, is a non-reducing disaccharide composed of two glucose molecules, with the molecular formula C12H22O11.
Trehalose is a typical stress metabolite that can form a unique protective film on the cell surface under harsh environmental conditions such as high temperature, high cold, high osmotic pressure, and dehydration, effectively protecting the biomolecule structure from being destroyed, thereby maintaining Life processes and biological characteristics of living organisms.
Trehalose is a proliferation factor for beneficial intestinal bacteria in the body, Bifidobacteria. It can improve the intestinal microecological environment, strengthen the digestion and absorption function of the gastrointestinal tract, effectively eliminate toxins in the body, and enhance the body's immune and disease resistance.
As a fat-soluble antioxidant, BHA is suitable for fatty foods and fat-rich foods. Due to its good thermal stability, it can be used under frying or baking conditions. In addition, BHA has a strong antioxidant effect on animal fats, but has a poor antioxidant effect on unsaturated vegetable fats. BHA can stabilize the pigment of raw beef and inhibit the oxidation of ester compounds. BHA combined with sodium tripolyphosphate and ascorbic acid can delay the spoilage of frozen pork chops, slightly extend the shelf life of spray-dried whole milk powder, and improve the shelf life of cheese. BHA can stabilize the color of chili peppers and chili powder and prevent oxidation of walnuts, peanuts and other foods. Adding BHA to baking oils and salt can preserve the flavor of baked goods and salty peanuts. Extend the shelf life of baked goods. BHA can be mixed with other fat-soluble antioxidants for better results. If used in combination with dibutylated hydroxytoluene, it can protect carp, chicken, pork chops and frozen bacon slices.

Because this sugar has unique biological functions and can effectively maintain the stability and integrity of intracellular biofilms, proteins, and active peptides in adverse circumstances, it is praised as the sugar of life and can be widely used in
food, cosmetics, feed, etc. every industry.:
1. Food industry
In the food industry, trehalose is currently being developed and researched for various uses considering its functions and characteristics such as non-reducing properties, moisturizing properties, anti-freezing and drying resistance, high-quality sweetness, and energy sources. Trehalose products can be applied to a variety of foods and seasonings, which can greatly improve the quality of food and increase the variety of foods, promoting the further development of the food industry.
Functional properties of trehalose and its application in food:
(1) delow starch aging
(2) delow protein denaturation
(3) Inhibit lipid oxidation and deterioration
(4) Flavoring effect
(5) Maintain the tissue stability and stability of vegetables and meat Preservation effect
(6) Long-lasting and stable energy source.
2. Cosmetics Industry
Since trehalose has strong moisturizing effect and various physiological effects such as sun protection and ultraviolet protection, it can be added to lotions, essences, and facial cleansers as moisturizers and protectants. It can also be used as lip balm and oral cleanser. , sweeteners and quality improvers such as oral flavoring agents. Anhydrous trehalose can also be used in cosmetics as a dehydrating agent for phospholipids and enzymes, and its fatty acid derivatives are also excellent surfactants.
