| Research Abstract |
Fats and Oils are easily deteriorated by oxidation. Lipid oxidation has been implicated not only in deterioration of food quality such as rancid flavor and taste, viscosity of oils and a decrease in nutritional properties, but also in causing a wide range of biological damages including heart diseases, aging cancer and etc. This study was aimed to increase oxidative stability and active oxygen scavenging ability in oils with the addition of herbs. The sesame salad oils added with five per cent of herbs'powders were stored for three months in dark place and separated from the powdres by the centrifuge. The oxidative stabilities were determented by oven test during storage at 60 C, TBA during frying process at 180C.Among twelve oils with fat soluble extracts from herbs, All herb oils showed strong oxidative stabilities compared to non- additional sesame salad oil, especially, clove, allspice, and oregano had high antioxidative effects. The active oxygen scavenging effects by DPPH radical were also observed particularly in sesame salad oil with clove, allspice and oregano.
The sesame salad oils with herbs were observed the possibility of utilization to dressing, pan-frying and deep-frying oils by sensory evaluation
