| Abstract: | Objective ] In order to explore industrialization process for lyeopene extraction from bitter melon aril and establish a new way of extracting lyeopene from tomato skin. Lyeopene extraction was carried out via extraction with organic solvent. Method] The aril was collected from bitter melon by artificial ripening. After fermentation and drying process, lyeopene was extracted from aril with mix organic solvent. Ex- traction conditions were optimized through orthogonal test including mixed solvent ratio, the ratio of solvent and aril material, extraction time and extraction times and so on. Result] The industrial amplification produce parameters as follows： the volume ratio mixed solvent of methyl- ene chloride to acetone is a 2：1, ratio of mixed solvent to bitter melon aril sample （V/IV） is 7：1 ml/g, the extraction time is 50 minutes, ex- traction times 3 times. Under the conditions, the extraction yield of lycopene from bitter melon aril was higher than 95%, lyeopene content in oil resin higher than 8% , the level of solvent residue was lower than 50 μg/g. Conclusion] The extraction conditions can be used to extract lycopene from bitter melon aril of industrialized production. Solvent residue lycopene meets the requirements of the national food standards. Lycopene extracted from bitter melon aril has economic value of development and utilization. |
