Five methods using aqueous/organic solvents for the separation of proteins from oils were compared. The extraction with acetone-hexane followed by amino acid analysis was found to be the most suitable method for isolation and quantification of proteins from oils. The detection limit of the method was 0.18 mg protein/kg oil, and the quantification limit was 0.6 mg protein/kg. The relative repeat...

the effect of various pesticides (diflubenzuro, malathion, mancozeb and carbendazim), disinfectants (calcium hypochlorite and formaldehyde) and oil cakes (sunflower and soy-bean oil cakes) commonly used as supplements in mushroom cultivation on the growth of the nematophagous fungus, arthrobotrys oligospora, was studied under in vitro conditions. carbenazim caused 99% inhibition of radial mycel...

An experiment was conducted to establish the effects of feeding refined soy oil (RSO) or whole soybeans (WSB) containing soy oil on DMI, animal performance, and enteric methane (CH4) emissions in young bulls. Thirty-six Charolais and Limousin cross-bred, young beef bulls (338 +/- 27 kg of BW, 218 +/- 17 d of age at the beginning of the experiment) were blocked by BW, age, and breed before being...

Jason Woodworth, Graduate Research Assistant Extrusion processing is an effective means of improving the nutritional value of whole soybeans fed to swine. Recently, Insta-Pro International has combined extrusion technology with expelling, an oil extraction process, to produce an extruded-expelled soybean meal (Insta-Pro ExpressTM extruder/press system). The resulting soybean meal contains sligh...

Three experiments using 864 crossbred feeder pigs were conducted to determine the effects of fat sources and a feed flavor in 3-wk receiving diets and a reduced nocturnal temperature regimen on commingled feeder pig performance. In Exp. 1, there was no response to a feed flavor on overall ADG or ADFI. Commingled pigs offered receiving diets containing 5% blended vegetable oil (5B) or 5% tallow ...

Whether PUFA diets affect inflammatory mediators in central and peripheral sites is not clear. We investigated the effect of high-fat PUFA diets on the expression of proteins involved in inflammatory pathways in hypothalamus, muscle, and liver. Male rats were fed for 2 months with either chow or high-fat diets enriched with either soy (n-6 PUFAs) or fish oil (n-3 PUFAs). The fish group had norm...

Low-resolution time domain nuclear magnetic resonance (TD-NMR) is an internationally recognized and commercially important analytical tool for measuring the oil content in oilseeds and oilseed residues. It is commonly employed as a simultaneous determination of oil and moisture content, as in ISO 10565 or AOCS Ak 495. Because the method is very fast, compared with oven drying to determine moist...

This experiment was conducted to determine the effect of different vegetable oil types on broiler energy expenditure, abdominal fat deposition and fatty acid profile of breast and thigh. A total number of 300 un-sexed day-old cobb 500 broiler chickens were used in a completely randomized design, consisted of five treatments (five different vegetable oil sources including soy, flaxseed, canola, ...

Epoxidized allyl soyate (EAS), a novel soy based epoxy resin, has been prepared by the process of transesterfication and epoxidation of regular food grade soybean oil. Two types of crosslinking agents were employed in this study. The effects of the concentration of EAS and the type of crosslinking agent on the dynamic mechanical behavior of the soy based resin system have been investigated. The...

Soybean provides health benefits such as reducing cardiovascular disease, reducing menopausal symptoms, weight loss, arthritis, diabetes, osteoporosis and brain function. It contains phytochemicals such as isoflavones, saponins and phytosterols that promote health benefits. Soy food products are perceived as healthy food and are considered an important part of the diet. More than 50% consumers ...
