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
Composition
The liquid glucose is the mixture of the following compounds: Glucose, Maltose, Maltodiose, Maltotriose, Dextrose, Dextrine
