Impact of post-harvest operations on paddy and milled rice quality.

Bonifacio E.P. | Duff B.
This study was conducted to assess the effect of milling and pre-milling operations on rice quality and to determine the relationship between price and rice (paddy and milled rice) quality using hedonic pricing model. The results indicate insignificant differences in paddy quality by mill types (commercial, village rubber roll and Engleberg mills). However, the quality of milled rice differed significantly with commercial mills producing the highest percent head rice. The hedonic pricing model demonstrates that in purchasing paddy, millers value moisture content and shape in the dry season and shape and potential whiteness in the wet season. For milled rice, no significant seasonal differences in quality were observed. Shape and apparent amylose content significantly affect the price of milled rice. The findings confirm that mill type affects milled rice quality and millers attach economic significance to certain grain quality characteristics. Considering the incentives to improve grain quality, refinement of technologies to achieve marginal improvement in existing technologies can be better established.
