Abstract

All types of parboiled rice got degraded when immersed in very dilute alkali, but the appearance of the degraded grain differed among the three classes of parboiled rice. Open-steam parboiled rice grains remained fairly chalky white; pressure-steam parboiled grains became transparent; and dry-heat (sand heating) parboiled grains remained chalky, but got longitudinally split. Alkali reaction could thus distinguish between the three classes of product. The reaction seemed independent of starch reassociation.
