Abstract:

The optimal technological parameters of cold pressed sesame oil were investigated by single factor and orthogonal experiments. Results indicated that the optimal extraction condition processing parameters were the sesame power granule size of 20 mesh, extraction temperature of 50 ℃, extraction time of 60 min and extraction pressure of 40 MPa. Under the optimal extraction conditions, the extraction of sesame oil was 43.46%. Meanwhile, the sesame oil extracted under the optimal extraction conditions was rich in antioxidant components without benzopyrene, and exhibited a better physicochemical properties and oxidative stability than ordinary sesame oil.

Key words: sesame oil, extraction, antioxidant activity, benzopyrene
