as lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on pgfm secretion, ovarian function and blood metabolites is investigated. in this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous holstein co...

the aim followed in this study was to investigate the effects of soybean oil (high in c18:2 n-6, an omega-6 fatty acid) and fish oil (high in epa 20:5 n-3 and dha 22:6 n-3, omega-3 fatty acids) on meat quality and on the fatty acid profiles in goat kids. twenty-four male kids were allocated through stratified randomization and on the basis of body weight (19.43±1.2 kg) into three equal groups. ...

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...

To circumvent drought conditions persisting during seed fill in the mid-south U.S. soybean production region, researchers have developed the early soybean (Glycine max [L.] Merr.) production system (ESPS), which entails early planting of short-season varieties. Because soybean supplies a preponderance of the world's protein and oil and consumption of soy-based foods has been associated with mul...

An electronic nose (e-nose) was used to characterize sesame oils processed by three different methods (hot-pressed, cold-pressed, and refined), as well as blends of the sesame oils and soybean oil. Seven classification and prediction methods, namely PCA, LDA, PLS, KNN, SVM, LASSO and RF, were used to analyze the e-nose data. The classification accuracy and MAUC were employed to evaluate the per...

Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do...

 The influence of five pure diets of isonitrogenous and isoenergic with different ratios of Clupeidae fish oil (F) and soybean oil (S) on growth, molting and survival of narrow-clawed crayfish, Astacus leptodactylus, was evaluated during an 8-weeks trial. As soybean oil replaced with fish oil in each treatment, gently. Test diets were inclusive F0/S100, F30/S70, F50/S50, F70/S30 and F100/S0 fis...

background: soybean oil is one of the highly consumed vegetable oil worldwide. nowadays, usage of genetically modified (gm) soybean seeds for soybean oil production is constantly increasing. the recommended methods for gmo detection are based on analysis of residual dna in vegetable oil and highly processed food. however, the successful amplification of isolated dna depends on the efficiency of...

Background The worldwide demand for new renewable sources of energy is rising every day [1]. Biodiesel is a green fuel made mainly from soybean oil, on average composed of 25% oleic acid and 13% palmitic acid, which negatively impacts its oxidative stability and freezing point, causing a high rate of nitrogen oxide emission [2,3]. To improve the quality and performance of soybean oil as biodies...

The first comprehensive life‐cycle assessment (LCA) for soybean biodiesel produced in the U.S. was completed by the National Renewable Energy Laboratory (NREL) in 1998, and the energy inventory for this analysis was updated in 2009 using 2002 data. The continual adoption of new technologies in farming, soybean processing, and for biodiesel conversion affects the life‐cycle energy use over time,...
