Oxygenated fatty acids are classified as secondary metabolites in wheat, produced by oxidation of free fatty acids (FFAs). Oxygenated fatty acids have significant impact on the organoleptic and sensory properties of food products and participate in r

Nutritional composition of oat kernels from 18 genotypes grown in six environments in North Dakota, U.S.A., was analyzed by chemical means. Of the macronutrients, mean starch concentration was 56.5%, protein was 18.1%, oil was 7.9%, neutral detergent

The oat grain is often subjected to different hydrothermal treatments to inactivate hydrolytic enzymes that can have undesirable effects on the end-product quality. Hydrothermal treatments may affect the functional properties of oat starch. The objec

Extraction protocols for β-glucan from oat flour were tested to determine optimal conditions for β-glucan quality testing, which included extractability and molecular weight. We found mass yields of β-glucan were constant at all temperatures, pH v

Effects of genotype and environment on (1→3), (1→4)-β-d-glucan (β-glucan) extractability, flour slurry viscosity, and β-glucan polymer fine structure in oats were tested. One environment had a severe negative effect on slurry viscosity as eval

Oxygenated fatty acids were identified in oat grain by gas chromatography-mass spectrometry. We hypothesized that most of these were the results of lipoxygenase activity. This hypothesis was tested by measuring concentrations of these compounds after

Oat (Avena sativa L.) kernels appear to contain much higher polar lipid concentrations than other plant tissues. We have extracted, identified, and quantified polar lipids from 18 oat genotypes grown in replicated plots in three environments to deter

Groat proportion is the groat yield from an oat dehulling process. We compared hand, impact and compressed-air dehulling to measure groat proportion, and evaluated sources of error. Hand dehulling was the simplest and most accurate method, because al

Commercial processing of oats for human consumption generally requires impact dehulling to isolate groats from the hull. Impact dehulling involves feeding oat grain into the center of a spinning rotor that expels the grain against the walls of the de

Consumers occasionally report greenish colors generated in their oat products when cooking in tap water. Here we have investigated pH and ferrous (Fe(2+)) ion as possible mechanisms for this color change. Steel-cut oat groats can turn brown-green col
