Trehalose is a kind of sugar that preserves life. "Trehalose is not only useful for the food industry. Other sugars do not have this performance. One of the most important fact about trehalose is that both exogenous and endogenous trehalose have the same protective effect on living body and biological molecules. Because the amount of endogenous trehalose existed in most living bodies so small that utilization of exogenous trehalose became increasingly important in the fields such as pharmaceutical, food, cosmetics, agriculture and biotechnology. In addition to be excellent activity protective reagent of protein medicines, enzyme, vaccines and other bio-products, trehalose is the key important component of keeping cell activity and cosmetics moisture. Furthermore, trehalose is a unique food ingredient which can avoid the food degradation and then keep the fresh flavor of original food. So, as the sweetener, trehalose is widely used in food process
The physical speciality of trehalose
1. Mild sweetness
Trehalose is only 45% as sweet as sucrose. It has a clean taste profile
2. Process stability
Trehalose is a non-reducing sugar and will not take part in Mallard reactions with amino acids or proteins during the manufacturing processing and storage even at elevated temperatures. Thus, trehalose can be favorably used in food and beverage where heat treatment is required or storage at high temperature.
3. Perfect heat and acid tolerance
Trehalose is very stable to heat and acid during processing and storage, and would not become colored and broken down even heated for 30min at 100, pH3.0.
4. Low solubility and excellent crystalline
Water-solubility of trehalose is as high as maltose while the crystallinity is excellent, so it is easy to produce the low hygroscopical candy, coating, soft confectionery etc.
5. Low hygroscopicity
Some foods themselves are not hygroscopic, but their hygroscopicity can rapidly increase once sugars such as sucrose and maltose is added, and then foods' original flavor and shelf life changed. Trehalose has a very low hygriscopicity and remains stable up to 95% relative humidity. Thus, trehalose can be used as sweetening in food process.
Application: Trehalose are widely used in food, drink, pharma, cosmetic area
