| Abstract: |
| By comparing the appearance quality, physicochemical index, antioxidant component and fatty acid composition, the differences in quality of aqueous enzymatic extracted sesame oil and other processed sesame oils(hot-pressed sesame oil, cold-pressed sesame oil, aqueous extracted sesame oil) were studied. The results showed that the apparance quality of aqueous enzymatic extracted sesame oil could meet the first grade product sesame oil standard with good appearance quality and light colour. The moisture and volatile matter contents in aqueous enzymatic extracted sesame oil was between that of cold-pressed sesame oil and aqueous extracted sesame oil, and the acid value, peroxide value and unsaponifiable matter content of aqueous enzymatic extracted sesame oil were the lowest. The antioxidant component (VE, sesamin, sesamolin) in aqueous enzymatic extracted sesame oil was the highest, but sesamol was not detected. The content of saturated fatty acid was the highest and the content of unsaturated fatty acid was the lowest in aqueous enzymatic extracted sesame oil when compared with other processed sesame oils. |
