Using trace metals, peroxide, acid and iodine values to characterize oils bleached using clays from Central and Eastern Uganda
The decrease in content of iron in the bleached oils was highest for all oils bleached. The content of copper showed the smallest change. The decrease in copper content for palm oils decreased from 0.2ppm to 0.1ppm when ...
The quality and characteristics of cotton and sunflower oil bleached using clays from Iliri, in North Eastern Uganda
(European Centre for Research Training and Development UK, 2017)
Bleaching is known to alter the composition of edible oils as it removes impurities and certain food nutrients. The characteristics of bleached oil are strongly related to type bleaching medium, temperature at which ...
How variation of turbidity of bleached oils characterizes purity oil and bleaching processes
Freundlich and Langmuir isotherms have always been developed using changes in absorbance of oils. In this study we have investigated use of changes in turbidity of oils to assess bleaching efficiency and develop Freundlich ...
Distinguishing kaolinites and smectite clays from Central and Eastern Uganda using acidity, pH, colour and composition
(Scientific Research Publishing, 2015)
The Langmuir isotherms of 1-aminobutane in isohexane slurries showed increase in clay acidity with increase in concentration of mineral acid used to leach the clay as well as the temperature at which the clay was thermally ...
