The objective of this research was to develop a method to predict the amount of total solids leached during rice cooking using light transmittance at 650 nm with an ultraviolet-visible spectrometer. Rice was cooked in excess water for different durations, the transmittance was measured, and the solids were determined gravimetrically after evaporation of the water. Results of leached solids obta...

BACKGROUND Among nonoccupationally exposed U.S. residents, drinking water and diet are considered primary exposure pathways for inorganic arsenic (iAs). In drinking water, iAs is the primary form of arsenic (As), while dietary As speciation techniques are used to differentiate iAs from less toxic arsenicals in food matrices. OBJECTIVES Our goal was to estimate the distribution of iAs exposure...

Rice is a major food source for much of the world, and expanding our knowledge of genes conferring specific rice grain attributes will benefit both farmer and consumer. Here we present novel dull grain mutants with a low amylose content (AC) derived from mutagenesis of Oryza sativa, ssp. japonica cv. Taikeng 8 (TK8). Positional cloning of the gene conferring the dull grain phenotype revealed a ...

(eds M.C.S. Wopereis et al.) 311 than white rice in Kumasi (the second largest city in Ghana), but this is not true for other markets in the country (Sakurai et al., 2006). Nigerians generally prefer cooked rice of a ‘harder’ texture than consumers in neighbouring countries. Watanabe et al. (2002a,b, 2006) showed that many grain quality characteristics such as grain breakage, grain whiteness af...
