What is Trehalose?

Trehalose is a type of sugar composed of two glucose molecules. It is naturally found in some plants, fungi, and invertebrates. Commercially, it is produced from starch using enzymatic processes.

Trehalose is used in food products as a sweetener and stabilizer. It is often favored because of its ability to retain moisture and improve the texture of products. Most of the research suggests that trehalose is a safe sugar alternative, although as with any sugar, moderation is encouraged.

When seen on a label, trehalose signals the product might aim for a stable texture and improved shelf life, often with a milder sweetness compared to regular table sugar.

Commonly found in: baked goods, confectionery, ice cream, cosmetics, processed foods
