Cereal Chem. 70(l):77-80 Soft white wheat flours from varied growing conditions were analyzed However, when the correction for protein content was not taken into for selected variables of gluten and components of flour lipid to identify account, total protein was shown to be negatively correlated with cookie those that are associated with baking quality as measured by cookie diameter. Among the...

Cereal Chem. 80(2):188–192 The sodium hydroxide (NaOH) test for determining wheat color class depends on the observation that on soaking in NaOH, red wheat turns a darker red and white wheat turns straw yellow. To understand the mechanism of this test, Raman spectra of wheat bran, wheat starch, ferulic acid, and whole kernels of wheat, before and after NaOH soak, were studied. The major observa...

The selenium content of the 1989 harvest of wheat used for bread making in Scotland ranged from 0.028 microgram/g dry weight for home-grown wheat to 0.518 microgram/g for Canadian wheat. The tonnage values indicate that 13.8% of the wheat used in bread making came from Canada. This reflects in a calculated dietary intake of 31 micrograms/d which is well below the recommended levels of 70 and 55...

Metabolic changes in spikelets of wheat varieties FL62R1, Stettler, Muchmore and Sumai3 following Fusarium graminearum infection were explored using NMR analysis. Extensive 1D and 2D 1H NMR measurements provided information for detailed metabolite assignment and quantification leading to possible metabolic markers discriminating resistance level in wheat subtypes. In addition, metabolic changes...

Poor micronutrient intakes are a major contributing factor to the high burden of micronutrient deficiencies in Côte d'Ivoire. Large-scale food fortification is considered a cost-effective approach to deliver micronutrients, and fortification of salt (iodine), wheat flour (iron and folic acid), and vegetable oil (vitamin A) is mandatory in Côte d'Ivoire. A cross-sectional survey on households wi...

Flours of wheat, chestnut, acorn and lupin were evaluated in relation to phenolic compounds, antioxidant activity, and oxalate content. At the chemical level the results show some variability between samples by type of flour, and the sample of chestnut flour presented the higher value of oxalate (0.00348 mg/100g) when compared to the other samples in the study. Considering the content of phenol...

Thirty-three samples of wheat of the 1982 crop year from Kansas and Nebraska were analyzed for deoxynivalenol, T-2 toxin, zearalenone, and aflatoxin. Deoxynivalenol was identified in 31 of 33 samples, zearalenone was identified in 3 of 33 samples, and aflatoxin B1 was identified in 23 of 31 samples. One 1982 wheat sample from Illinois and one from Texas were also contaminated with deoxynivaleno...

Purpose: To investigate the effects of oligosaccharides on the functional properties of wheat starch. Methods: The blue value, retrogradation and pasting properties of wheat starch were determined. In addition, water activity (Aw), melting enthalpy and melting temperature of wheat starch paste were analyzed. Results: Fructo-oligosaccharide (FOS) and xylo-oligosaccharide (XOS) inhibited the retr...

The influence of humidity and low temperature on the αamylase activity and isoenzyme composition of grains of different wheat varieties have been studied. The identified samples of varieties have significant difference in the level of enzyme induction under the impact of high humidity and low temperature. It is proposed to use this methodological approach for testing genotypes and wheat breedin...
