Influence of storage condition and added vitamin E on oxidation stability of edible sunflower and nigger seed oils produced and sold around Bahir Dar city, Ethiopia
Author(s): Zelalem Gizachew*
In human nutrition, fats are physiologically important food constituents but also the components most liable to oxidative degradation. This study was carried out in order to probe the extent of oxidative alterations in Sunflower Oil (SFO) and Nigger Oil (NO), subjected to daylight and dark storage conditions with, and without added vitamin E, over a period of 5 weeks storage. The magnitude of oxidative changes was monitored by the periodical measurement of acid value, peroxide value, and induction time throughout storage time. The acid value of sunflower oil increased from initial value 4.5 mg KOH/g to (24.7, 19.64, 16.83, and 12.34) mg KOH/g, and of nigger oil from 6.2 mg KOH/g to (21.3, 17.95, 16.83 and 11.22) mg KOH/g for oil samples kept in daylight, dark, daylight+vitamin E, dark+vitamin E for 5 weeks. Like the acid value, the peroxide value of sunflower oil increased from 2.2 me.. View more»
