Abstract

Husked, hand-pounded, milled raw rice and parboiled milled rice obtained from the same strain of paddy (Halubbulu) were infeste<i by Calandra (Sitophil=) ory.ra~ (rice weevil) for a period of eight months and the changes brought about in the different samples due to infestation have been studied. The results show that husked rice was infested to a greater extent than the other samples and developed an unhealthy appearance withi wo months of infestation. PaTboiled and raw, milled samples of rice weTe found to be least susceptible to infestation. Infestation of the rice grain increased the loss of starch in the gruel dUling cooking, the loss being ma."imum in the case of husked rice. An appreciable increase in the acidity of fat and a decrease in the thianline content due to insect damage were observed. No significant difference was noted in the other constituents of the grain, such as total nitrogen and soluble nitrogen: Some correlation was observed between the weight/volume mho of uncleaned grain and the proportion of dust, loss iu total weight, Joss in thiamine and iusect population.
