Samples of cassava starch used for gel preparation
and subsequent coating formulations contained
48.3% of granules of 0.42 mm diam. retained on sieve
40; 11% of 0.25 mm diam. retained on sieve 60; 12%
of 0.177 mm diam. retained on sieve 80, 12.3 % of
0.149 mm diam. retained on the sieve 100, 11% of
0.105 mm retained on sieve 140 and 5.4% smaller
than 0.105 mm in diameter. Within this range of particle
sizes, the time for water absorption and to form
the gels was between 1 and 2 min in 300 mL preparations
at 80°C.
