Abstract

In this study the identification of chemical and biochemical characteristics of balangu seed oil (Lallemanthia royleana) and their parameters were investigated under accelerated aging conditions at 24 h, 48 h and 72 h at 41°C and 100% RH in a completely randomized design. The results showed that balangu seed oil content was 19.26%.Fatty acid profiles were 90.71% of unsaturated fatty acids (USFA) and 9.29% of saturated fatty acids (SFA), also the linolenic acid (C18:3), oleic acid (C18:1) and palmitic acid (C16:0) were important of PUSFA, MUSFA and SFA oil seeds, respectively.The antioxidants of oil seeds include 427.8 ppm tocopherols and 210 ml.l-1 of polyphenols. The results showed that 15.2% reduction in oil seed under accelerated aging treatment, also this treatments was the cause of increase of SFA compared to USFA. The oxidation and peroxide production peak was between control and 24 h of accelerated aging treatment. Oil resistance (rancimat) in the 72 h of aging treatment was 1.5 times less than to the control. The germination value (GV) was 1.6, 2.5 and 4.5 higher than the accelerated aging treatments, respectively. In general, it is likely that the changes of chemical and biochemical characteristics of seed oil is happened by oxidative enzymes and this condition is quicker in deteriorated balangu seeds
