Liquid Glucose
|
| Introduction: |
Liquid Glucose, a highly viscous
material, is at present extensively used as sweetening
agent in confectionery , bakery and other food
preparations. The product first came into existence
in the field of carbohydrate sweetening soon after
the second World War. The uniqueness of this product
is its high viscosity, sticky nature and ability
to control sweetening , which makes liquid glucose
a good doctoring agent for confectionery purpose.
Starch, the most abundant carbohydrate obtained
from plant kingdom, is the starting raw material
for making Liquid Glucose. Starch is commonly
produced from corn, millets and tubers; which
grows proliferously in sub-tropical countries.
Starch is isolated from the plant source as an
aqueous suspension of pure granules. In developed
and developing countries, separation of starch
granules from the aqueous suspension is done in
a sophisticated way involving high investment.
In India, although the starch production from
the various sources is mostly confined to small
scale sector/cottage industries, some of the big
industries also separate starch for their captive
consumption.

| Process |
Although several attempts have
been made to produce Liquid Glucose from crude starch
produced by these cottage industries by different
agencies, but the result was not very satisfactory.
However, through the several years of in-house R
& D effort, development of a economic technology
to produce "Liquid Glucose" have been
achieved successfully. The process utilises enzyme
for converting starch in glucose in two steps and
replaces the traditional acid hydrolysis route.
The process has achieved a commercial success. The
major advantages of the process are :
- Utilises crude starch
- Higher yield
- Involves low temperature simple operations.
- Consumes less power
- Environmental friendly
- Low capital investment and low manpower requirement
