Potato Starch .
- A natural starch from
wheat or corn which has been chemically modified, the resultant
starch is oxidized starch or Dialdehyde starch.
- DAS is a polymeric
dialdehyde prepared from selective oxidation of starch by periodate
ions which cleaves the C2-C3 bond of the anhydroglucose units of the
starch polysaccharide chain to form the dialdehyde groups.
- Synonyms are
polydialdehyde, oxidized starch, polymeric dialdehyde,
- There are many uses
including the paper industry, where it has been mainly to improve
the wet strength of consumer products. These products include toilet
paper and paper towels.
- A reactive polymer
with low toxicity, considering its reactive dialdehyde functional
groups, similar to glutaraldehyde.
- DAS is essentially a
highly modified starch in which the Hydroxy groups are
selectively attacked by periodic acid, severing the C-2 to C-3 bond
to form dialdehyde starch.
- Obtained by oxidation
of starch with periodic acid at controlled temperature and pH.
- The highly reactive
Dialdehyde groups in starch can be used as cross linking agents.
Most of the
applications are based on a cross linking reaction, eg. cellulose in
paper, cotton in textiles, with proteins, pharmaceuticals and
- The capital investment
for a capable of producing 120 tones Dialdehyde starch per annum has
been estimated at Rs. 5 Lakhs. The material work costs upto Rs.5 per
- It has wide
application in tanning industry apart from this it also used in
plywood industry, as a binding material in tobacco industry in
protective coating industry.
- In the form of
solution, it can be used as masked chrome tanning agent & increase
