In the Central Plateau of Burkina Faso, grain sorghum [Sorghum bicolor (L.) Moench] is the major cereal crop used to produce the traditional beer called dolo. Grain sorghum grain samples collected in 2004 and 2005 from experiments combining five water management techniques and four fertilizer treatments in a randomized complete block design with a split plot arrangement of treatments were analy...

Background Deoxynivalenol (DON) is one of the most common mycotoxins found in cereal grains. Objective The purpose of this survey was determination of difference between DON fungal toxin pollution level in raw wheat flour and bread. Methods: In this In the present analytical-cross-sectional study, to determine DON level, 44 subjects were random samplings of wheat, bread and flour (Lavash and ...

A new product implicated in cereal grain polysaccharide cross-linking has been authenticated by independent synthesis. Saponification of cereal grain fiber releases the RRRS/SSSR-isomer of 2,5-bis-(4-hydroxy-3-methoxyphenyl)-tetrahydrofuran-3,4-dicarboxylic acid. The parent ester logically derives from 8-8-coupling of ferulate followed by water addition to one of the incipient quinone methide m...

A simple, new aptamer-photonic crystal encoded suspension array was designed to simultaneously quantify and qualify ochratoxin A(OTA) and fumonisin B1(FB1) in cereal samples. The aptamers of OTA and FB1 were immobilized on the surfaces of photonic crystals by chemical bonding. When the target mycotoxins appear in a sample, the fluorescence-labeled complementary DNA of the aptamer dissociates fr...

Hydrogen can be produced from fermentation of sugars in wastewaters, but much of the organic matter remains in solution. We demonstrate here that hydrogen production from a food processing wastewater high in sugar can be linked to electricity generation using a microbial fuel cell (MFC) to achieve more effective wastewater treatment. Grab samples were taken from: plant effluent at two different...

Objectives: Aflatoxin contamination of cereals and poultry feed causes significant financial loss poses a risk withserious health implications for both humans animals. Present research was conducted to check the occurrence ofaflatoxins B1 in including pulses evaluate potential different techniques inremoving aflatoxin from cereals. Methodology: 112 cereal samples which comprised varieties used ...

Cereal Chem. 65(3):182-185 Total and water-soluble pentosans were determined in flours milled from absorption and soluble pentosans were correlated, and the correlation hard red winter, hard red spring, and soft red winter wheat cultivars grown coefficient increased if the results were expressed on a constant protein at various locations and environments; in two sets of commercial airbasis. In ...

The cereal species, of central importance to our diet, began to diverge 50-70 million years ago. For the past few thousand years, these species have undergone largely parallel selection regimes associated with domestication and improvement. The rice genome sequence provides a platform for organizing information about diverse cereals, and together with genetic maps and sequence samples from othe...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
