| Abstract: | Using the extraction oil rate of paprika seeds and the extraction amount of linoleic acid as evaluation indicators,the influence of particle size of paprika seeds,extraction pressure,extraction temperature and extraction time were studied.The optimal extraction conditions were as follows: particle size of paprika seeds 60 mesh,extraction pressure 30 MPa,extraction temperature 55 ℃,extraction time 40 min.Under these conditions,paprika seeds oil extraction rate was 29.40%,the extraction amount of linoleic acid in paprika seeds reached 145.07 mg/g. |
