Application of cassava in nonfood uses
Starch makes a good natural adhesive.
There are two types of adhesives made of starches, modified
starches and dextrins: roll-dried adhesives and liquid adhesives.
The application of cassava in adhesives
continues to be one of the most important end uses of the
product. In the manufacture of glue the starch is simply gelatinized
in hot water or with the help of chemicals. For conversion
into dextrin it is subjected separately or simultaneously
to the disintegrative action of chemicals, heat and enzymes.
In gelatinized starch adhesives, quality
requirements are such that the medium-quality flours can be
used. In dextrin manufacture, the demands are much more exacting:
only the purest flours with a low acid factor are acceptable.
Cassava dextrin is preferred in remoistening gums for stamps,
envelope flaps and so on because of its adhesive properties
and its agreeable taste and odor.
