Hydrogenation of Edible Oils
and selective hydrogenation of liquid oils is practiced to change the physical proper~ies for solid fat products or to improve the stability of highly unsaturated oils during high temperature use. Hydrogenated ' vegetable oils are used in the formulation of shortenings, margarines, salad/cooking oils, and other foods. In the United States, the total consumption of visible and non-visible fat is...
متن کاملChlorophyll Removal From Edible Oils
The chlorophyll content of canola oil, especially when extracted from frost-damaged seed is high, and results in dull, dark brown oil unless very large quantities of bleaching clay are used. We found that treatment with phosphoric acid, under vacuum in the absence of moisture precipitates most of the chlorophyll. At 140°C 2400 mg/L phosphoric acid precipitated 98 % of the chlorophyll in canola ...

متن کاملProduction of Biodiesel from Different Edible Oils
Different vegetable oil based biodiesel (FAMES) were prepared by alkaline transesterification using refined oils as well as waste frying oil (WFO). Methanol and sodium hydroxide are used as catalyst under similar reaction conditions. To ensure the quality of biodiesel produced, a series of different ASTM Standard tests were carried out. In this context, various testwere done including viscosity...
متن کاملTerahertz time-domain spectroscopy of edible oils
Chemical degradation of edible oils has been studied using conventional spectroscopic methods spanning the spectrum from ultraviolet to mid-IR. However, the possibility of morphological changes of oil molecules that can be detected at terahertz frequencies is beginning to receive some attention. Furthermore, the rapidly decreasing cost of this technology and its capability for convenient, in si...
