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 and flavour, freezing point depression
and osmotic pressure. Other properties such as cohesiveness,
bodying characteristics, foam stabilization and prevention of
sugar crystallization are inversely proportional to the
increasing DE.
The reducing action of glucose makes it incompatible with strong
oxidizing agents, which has advantages of its own.

Applications:
1)
A food technologist will use it to control crystallization, body
appearance, sweetness, osmotic pressure and as a '
preservative in hard-boiled candies, jams and jellies.
2)
A baker will ferment it with yeast for raising the product. A
dairyman will add it to ice cream, to improve the texture and
palatability of the ice cream and enhance flavours. It is
usually the cheapest source of total solids. It has become
common in the dairy industry to substitute all or a portion of
the sucrose content with sweetners derived from corn syrup.
This sweetner is reported to contribute to a firmer and
chewier body to the ice cream, it is an economical source of
solids, and improves the shelf life of the finished product.
3)
A chemical engineer will find the use of liquid glucose as a raw
material for GLUCONIC ACID, KOJIC ACID and CITRIC ACID.
4)
A pharmacist will add Liquid Glucose in cough syrup and vitamin
based tonics. Will also use it as a base of artificial honey.
He also uses it as a granulating agent and for tablet coating.
5)
A tobacco specialist will use liquid glucose in curing and
imparting flavour in tobacco.
6)
A tanner will use Liquid Glucose to enhance weight and ensure a
softer texture. He will also use it to precipitate chrome into
the body of the leather due to its reducing action. He will
also add it to shoe polish to prevent it from caking and to
help it to give a better and quicker shine.
7)
Sulphur free glucose is available for specific customers with SO2
content of 40 ppm max.
