Abstract

Abstract. The incidence of diabetes in Indonesia has been increasing year by year.
Diets with a low glycemic index and high resistant starch foods can assist diabetics in
controlling their blood glucose levels. Diabetics are known to have micro-nutrient
deficiencies of chromium, magnesium and vitamin D that can be overcome by
consuming parboiled rice fortified by use of a coating method. The fortification of
parboiled rice (premix rice) can be achieved by coating with HPMC (hydroxypropyl
methyl cellulose), MC (methyl cellulose), CMC (carboxyl methyl cellulose), gum arabic
and rice starch. This research aimed to evaluate the levels of resistant starch, glycemic
index and fortificants of premix rice coated with different concentrations and types of
edible coating materials. This research used completely randomized design, with
treatments to the concentrations and the types of edible coating (HPMC, CMC, MC,
gum arabic and rice starch). The concentrations of edible coating were 0.15%, 0.2%
and 0.25% for cellulose derivative coatings; 25%, 30%, 35% for gum arabic and 2%,
3.5% and 5% for rice starch. This research shows that fortified premix rice coated with
various concentrations and types of edible coating materials is high in resistant starch
and has a low glycemic index. The coating treatment affects the levels of magnesium
and vitamin D, but does not affect the levels of chromium in parboiled rice. The premix
rice with a low glycemic index and high nutrient content (chromium, magnesium and
vitamin D) was premix rice coated by CMC 0.25% and HPMC 0.25% with glycemic
indeces of 39.34 and 38.50, respectively.
Keywords: coating material, fortificant, glycemic, rice.
