INTRODUCTION:
Trehalose is a naturally occurring disaccharide containing two glucose
molecules bound in an α,α-1,1 linkage. This structure results in a
chemically stable, non-reducing sugar with many important functional
characteristics. Trehalose is commonly found in nature, provides
a source of energy, and has been shown to be a primary factor in
stabilising organisms during times of freezing, drying and heating.
Trehalose is consumed as part of a normal diet in mushrooms, honey,
lobster, shrimp and foods produced using baker’s and brewer’s yeast.
Trehalose has been determined to be generally recognised as safe
(GRAS) as a multipurpose ingredient for all uses in food, including
as a sweetener, stabiliser, thickener and flavour enhancer, in general
accordance with current good manufacturing practices. It has a
uniquely high glass transition temperature for a disaccharide, is nonbrowning,
and will not hydrolyse at low pH or high temperatures.
This results in more stable colours and flavours in foods to which
it is added. Trehalose is 45% as sweet as sucrose when compared
in a 10% (w/v) solution and is stable at up to 94% relative humidity.
The low hygroscopic nature of trehalose dihydrate results in a freeflowing,
stable dry product. As a non-reducing sugar it does not
react with amino acids or proteins to initiate Maillard browning.
