Description
White, odorless, sweet-tasting powder.
Trehalose is a disaccharide, two simple sugars in one molecule.
In trehalose , the two sugars are both glucose.
Trehalose, is 45% as sweet as sugar. It does not brown like
sugar, and has a very low hygroscopicity (moisture attraction),
so it stays free-flowing and dry.
It does not brown when heated, it does not promote bacterial
growth or tooth decay as much as sugar, and it is less attractive
to moisture.
Trehalose is found in honey, breads, beer, and seafood.
Uses
Trehalose is used in foods as a sweetener, a stabilizer and
thickener, and a flavor enhancer. It is also used as a cryopreservation
additive, where it protects cells from the effects of freezing
and drying.
Trehalose, which is composed of two glucose molecules, is
metabolized in an identical manner as other disaccharides
(sucrose, maltose and lactose). After ingestion, trehalose
is enzymatically broken down in the small intestine into two
glucose molecules, which are then absorbed into the body by
an active transport mechanism. Glucose is then utilized in
the natural metabolic processes of life. Now trehalse has
been shown to be a suitable energy source when consumed before,during
and after exercise. The properties of trehalose, which make
it particularly suited for products are:
-does not promote excessive insulin release
-lower peaker glucose and more sustained energy release
-empties quickly from the stomach
-low caries-promoting properties
-non laxative |
