Total milled and head rice recoveries of paddy as influenced by its physico-varietal characteristics

Abstract

Eleven paddy varieties representing different growth durations ranging from 100-190 days were tested for their milling quality (total milled and head rice) and bending strength at three levels of moisture content (12%, 14% and 16%). Used were five IR varieties and six Philippine traditional varieties. Results of the study show that grain moisture content and variety had profound effects on the milling quality. Higher values of total milled rice and head rice were observed at lower moisture content levels of 12%, wet basis. Bending strength of grains was inversely related to grain moisture content. Grains at lower moisture content levels had harder kernels as shown by their higher values of bending strength. This further explains the phenomenon on why milling at lower moisture content levels has higher values of total milled and head rice recoveries. Results of the study also reveal that the milling quality was also a function of growth duration as shown by the increasing trend of milling quality, particularly head rice recovery, with increasing growth durations.
