Abstract:Bitter almond oil was extracted by n-hexane and the decolorization of the achieved oil was investigated. The results showed that the fat content in bitter almond was 49.58%. The optimum extraction parameters with n-hexane were temperature 65 ℃, time 5h and solid/ liquid ratio 1:10, under which the oil yield reached 92.0%. The optimum decolerization parameters with active white soil as decolorizer were: decolorizer dosage 10%, temperature 70℃and time 55min. The stability of the bitter almond oil showed that 0.01% PG as antioxidant significantly enhanced the oil stability.
