Suitable for manual, auto-analyser and microplate formats.

INTRODUCTION:

Trehalose is a naturally occurring disaccharide containing two Glu cose

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.
