How to reduce stickiness of thermoplastic starch?

Question

Currently I try to produce thermoplastic starch (TPS) using cassava starch and glycerol via melt processing technique. However the surface of TPS quite sticky. Any suggestion to reduce it stickiness? Thanks!

Answer 1

If you increase the % of glycerol, it may reduce stickiness.

Please refer following link for detailed study.

" the effect of glycerol contents on physical properties of cassava starch"

0, 15, 30 and 45g glycerol/100g starch

those with 0 or 15% of glycerol due to a ‘sticky’. character
