- STARCH-BASED INDUSTRY
Starch is produced from grain or root crops, and its usage
diversified, and vary with the continuous economic and
technological developments. In Vietnam, root crops, especially
cassava, have been the traditional sources of starch for
use in food products. Starch can be classified into two
types ¡X native and modified. Native starches are produced
through the separation of naturally occurring starch from
either grain or root crops, such as cassava, maize and
sweet potato, and can be used directly in certain food
production such as noodles.
For those characteristics which are unattainable with
native starch, it can be used for other industrial applications
through a series of modification steps. Modification can
be as simple as sterilizing products required for the
pharmaceutical industry to highly complex chemical modification
to confer properties totally different from the native
starch.
Simple modification is represented by washing, air classification,
centrifugation and pre-gelatinization. The later process
can be done in many forms from boiling in crude pots to
drum dryers to modern multi-screw extruders. Modified
starch products are used in the food, paper and textiles
industries.
The most common non-food applications for modified starches
are as follows:¡X
The Directors expect that in the future, the starch-based
product industry, both in Asia and the rest of the world,
will develop towards the production of higher-valued modified
starches from root crops, including cassava. The principal
raw materials for modified starches are corn starch and
cassava starch in Asia, maize starch in North America
and potato starch in Europe. As the starch-using industries,
such as the food industry, the paper industry and the
textile industry, are expected to continue to develop
in Asian countries, the Directors believe that the range
of starch-derived intermediate and end-products produced
from cassava will continue to expand.
The total revenue for starch and starch-based products
in the PRC in 2001 was approximately RMB14,606 million
(equivalent to approximately US$1,848.9 million), representing
an increase of approximately 15.8 per cent. as compared
with that in 2000. The demand for starch-based products
by food and non-food industries in Asia is also growing
steadily. It is expected that the demand for modified
starch, particularly
for non-food industries, will grow at a faster pace than
the demand for native starch.
