ABSTRACT
Treatment
of used vegetable oil (kings oil used for frying fish, chin-chin and power oil
used for frying fish, chin-chin) was done using locally produced absorbent
(kaolin clay, ultisol clay, carbonized eggshell and uncarbonized eggshell).
Sixteen oil samples were produced after the treatment process, four untreated
oil samples and two control, samples were evaluated for the specific gravity
ranged from 0.69 - 0.96, pH 5.13 - 7.80, peroxide value 0.16 - 4.55, free fatty
acid 0.27- 9.86, Refractive index 1.08 - 1.88, iodine value 38.09- 48.33,Acid
value 0.54-19.61, color 0.02- 0.71, saponification value 150.18 - 191.62 and
sensory evaluation, The parameters were rated on a nine point hedonic scale and
analysis of variance (ANOV A) and significant difference (p<0.05) were
tested using the Duncan multiple range test. There is degradation in the
physicochemical properties of the vegetable oil after use, it was deduced that
among the treatments used, utisol and kaolin performed better than other treatments.
However the sensory evaluation revealed that Uncarbonized eggshell and ultisol
performed optimally.
