Abstract

Water uptake at 80 degree C and starch-iodine blue value at 65 degree C, both expressed as percentage of the respective parameter at 96 degree C, gave good inverse estimates of the gelatinization temperature of rice. The equilibrium moisture content on soaking in water was 28-29% in indica, and 30-31% in dwarf indica and japonica rice. Similarly the fraction of total amylose soluble in water (96 degree C) was around 50% in indica and japonica, but 36% in dwarf indica. Dwarf indica rice viscogram showed a rather high setback value. The blue value of the excess cooking water of rice gave no useful information. Varieties with less than 25% amylose gave C-type alkali reaction.
