3.1. Effect of glycerol concentration on amylose removal
Glycerol is regarded as GRAS (Generally Regarded as Safe) substance
for food and drugs application. The effect of glycerol concentration
used in treatment on amylose content of starch is
presented in Table 1. Amylose content of rice flour starch
decreased after treatment. By employing 77% alkaline glycerol,
amylose content of BRF can be reduced to 1.43% with a yield of
80.42%, which indicates that glutinous rice flour (coded as SYNGRF)
was successfully obtained.
