The occurrence of sterigmatocystin (STC) in paddy and processed rice samples produced in Italy was surveyed. After extraction and purification, STC was analysed using HPLC-MS/MS. STC was detected in all paddy rice samples (n = 49), in the range 0.29-15.85 μg·kg-1. As regards processed rice, a widespread contamination was found in brown and parboiled rice. All the brown rice samples were contami...

Long terminal repeat (LTR) retrotransposons are the major class I mobile elements in plants. They play crucial roles in gene expansion, diversification and evolution. However, their captured genes are yet to be genome-widely identified and characterized in most of plants although many genomes have been completely sequenced. In this study, we have identified 7,043 and 23,915 full-length LTR retr...

Cereal Chem. 75(1):129–136 Several varieties of rough rice that were either stored for an extended period of time or freshly harvested were conditioned to initial moisture contents ranging from 10 to 17%. After the individual kernel moisture content distributions were measured, the samples were soaked in water at temperatures ranging from 10 to 40°C. The samples were then dried and milled. The ...

Sixteen red rice accessions from the southern United States were studied for their physical, milling, pasting, and thermal properties, chemical composition, and starch fine structure relative to cultivated medium- and long-grain rice varieties. All red rice samples were medium-grain, but their physicochemical properties were different from those of Bengal, a cultivated medium-grain rice. Their ...

Increased consumption of whole grains has been associated with reduced risk of developing major chronic diseases. These health benefits have been attributed in part to their unique phytochemicals. Previous studies on black rice mainly focused on anthocyanins. Little is known about the phytochemical profiles and antioxidant activities of different black rice varieties. The objective of this stud...

We reported previously that the pellagragenic property of corn protein is not only low l-tryptophan concentration but also the lower conversion percentage of l-tryptophan to nicotinamide; the amino acid composition greatly affected the conversion percentage. The amino acid value of wheat protein is lower than that of rice protein. In the present study, we compare the conversion percentages of l...

Abstract The aim of this research is to expand the knowledge on description grains breakage energy. In effect a model describe rice and corn energy in dependance size was developed. This achieved by linking level grinding with properties material (particle size) loading conditions. selected (rice corn) were subjected loads (compression cutting) testing machine. Based force-displacement curves, ...

background: this study has used biomarker of exposure-effect continuum to examine the biological characteristics of organophosphate (op) toxicity and its genotoxic effect among rice farmers.   materials and methods : a cross-sectional study was conducted among 160 pesticide exposed rice farmers and 160 adults from the fishing village as the unexposed group. they share the common socio-economica...

Germination and seedling growth of major cereals treated with Moringa oleifera leaf extracts was investigate at University of Zambia. Aqueous extract of Moringa oleifera at the ratio of 1:10 (w/v) were sprayed on seed of maize (Zea mays. L.), rice (Oryzae sativa.L.), sorghum (Sorghum bicolor. L.) and wheat (Triticum Aestivum. L.) in a growth room at 25C for 14 days. The data were subjected to a...
