Alternariol and alternariol monomethyl ether are commonly associated with weathered grain sorghum. Production of these metabolites and altenuene by isolates of Alternaria alternata was evaluated on various sterile grain substrates. At 35% moisture content and 25 C, metabolite yields were highest on rice, intermediate on sorghums, and lowest on wheat and yellow corn. Fourteen-to 21-day cultures ...

Cereal Chem. 88(4):414–420 Starch can be classified into rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS) according to its resistance to amylolytic enzymes. This study investigated the effects of cultivar and feedstock under varying parboiling conditions on the physicochemical properties and starch fractions of parboiled rice. Rice (rough or brown) was ...

An empirical rate equation was developed to predict head rice yield reduction for rough rice exposed to moisture adsorptive conditions. Time of exposure, initial moisture content, and relative humidity were significant to the reductions in head rice yield caused by moisture adsorption. An equation used to predict the number of kernels which fissured upon exposure to various environments was mod...

a cause for breakage of rice kernels during the whitening process could be assumed to be due to the produced heat. it is partly because of abrasion and friction of grains produced by contact against themselves and/or against cone and concave. in this study the effect of different temperatures of brown rice on rice kernels' breakage during the whitening process was investigated. khazar cult...

As variations in kernel uniformity can affect rice milling performance, limited thickness-grading to remove thin kernels was evaluated for effects on milling yields. Along with unfractioned (UNF) rice of four long-grain cultivars, rough rice was mechanically sieved, resulting in two thickness fractions, Thick (>0.079 inch) and Thin (<0.079 inch). Milled rice yield (MRY) and head rice yield (HRY...

Adults of Rhyzopertha dominica (F.), the lesser grain borer, were exposed on four varieties of rough rice with Dobie indices of susceptibility of 1.1 to 1.1 (low), and four varieties with Dobie indices of susceptibility of 3.4 to 3.8 (high). The varieties with low and high Dobie indices were classified as resistant and susceptible, respectively, to R. dominica. The purpose of the study was to e...

Rough rice (cv. Cypress) from the 1995 season was harvested, dried, and stored in laboratory-scale studies. Treatments included pre-drying conditions, drying conditions, storage temperatures, and storage durations. Temporary wet storage prior to drying affected cooking properties (p<0.005) and peak viscosity (p<0.005). Drying treatments affected head rice yield (p<0.05), cooking properties (p<0...
