Characterization of ozonated vegetable oils by spectroscopic and chromatographic methods.
In this work the effect of ozonation on olive oil, soybean oil, oleic-, linoleic- and linolenic acid was studied. The effects of ozonation time on the oils and acids were analyzed by 1H, 13C NMR. Further, the peroxide- and acid values, the viscosity and the molar mass were determined for pure and ozonated oils. The fatty chains in both ozonated oils showed a gradual decrease of unsaturation wit...
متن کاملEvaluation of various extracted vegetable oils, roasted soybeans, medium-chain triglyceride and an animal-vegetable fat blend for postweaning swine.
A total of 280 crossbred pigs weaned at 21 d of age and weighing approximately 6 kg were utilized in five replicates to evaluate pig growth responses when fed a basal diet or one of several dietary lipid sources during a 4-wk postweaning period. A basal corn-soybean meal-corn starch-dried whey diet was compared with diets supplemented at a 7.75% level with one of the following lipid sources: co...
متن کاملLubricant basestocks from vegetable oils
Oil Chemical Research. USDA l-ARS-NCAUR. 1815 N. U;liuersity Street, Peoria, IL 61604, USA Accepted 8 October 1999 Compared to the lubricants made of petroleum, vegetable-based lubricants are much more biodegradable but inferior in many other technical characteristics. The basestock typically contributes to more than 80% of lubricant and must meet performance criteria in such aspects as cleanli...
متن کاملThe Determination of Stigmastadienes in Vegetable Oils
The development by collaborative study of a standardised method for the determination of the stigmastadienes content in vegetable oils is described. The procedure involves the isolation of the unsaponifiable matter in the oil ands its fractioning on a silica gel column. The fraction containing the steroidal hydrocarbons is then analysed by capillary gas chromatography and the quantitative asses...
متن کاملVegetable oils as protectants against nematode infections.
In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...
