INTRODUCTION
The partial hydrolysis of starch slurry by acid or enzyme
gives an end product which is commonly known as Liquid
Glucose (Sweetose), Corn Syrup or Glucose. Chemically,
Liquid Glucose is a mixture of the entire spectrum of
carbohydrate molecules derived by breaking the long
chained molecules of polysaccharides contained in starch
slurry. By adjusting the content of the ingredients,
Liquid Glucose of various DE (Dextrose Equivalent) can
be obtained for varied end uses.
Liquid Glucose (sweetose) is a clear,
colourless, viscous solution making it compatible with
the physical properties desired in the end products
Chemically, Liquid Glucose has functional properties
such as high fermentability, viscosity, humectancy -
hygroscopicity, sweetness, colligative properties and
its role in Maillard's reaction.
The properties of Liquid Glucose are
directly related to the DE (Dextrose Equivalent) and
so are its effects an flavour, freezing point depression
and osmotic pressure. Other properties such as cohesiveness,
bodying characteristics, foam stabilisation and prevention
of sugar crystallisation are inversely proportional
to the increasing DE.
The reducing action of glucose makes
it incompatible with strong oxidising agents, which
has advantages of its own. |
