| titleOfInvention | Method for extracting squalene from amaranthus hypochondriacus seeds in entrainment mode and separating and purifying squalene in supercritical mode |
| abstract | The invention discloses a method for extracting squalene from amaranthus hypochondriacus seeds by entrainment and supercritical separation and purification, which comprises the following steps: (1) deodorizing the amaranth seed oil to obtain amaranth deodorized distillate; (2) performing methyl esterification on the amaranthus hypochondriacus deodorized distillate by using biological enzyme as a raw material, and washing the amaranthus hypochondriacus deodorized distillate with water to obtain a methyl ester liquid filtrate; (3) removing fatty acid methyl ester in the methyl ester liquid filtrate by reverse phase column chromatography; (4) performing ion exchange on the product in the step (3) by using basic ion exchange resin to remove tocopherol; (5) and (3) performing supercritical extraction and enrichment on the product in the step (4) to obtain squalene essential oil, effectively removing tocopherol and sterol in a compound aggregated by tocopherol-squalene and sterol-squalene in the extraction process, wherein the reaction condition in the process is mild, the squalene is prevented from being oxidized, the obtained squalene is high in purity and extraction rate, and meanwhile, the crude purification is performed on the high-added-value product of the grain amaranth, so that the comprehensive utilization value of the grain amaranth is improved. |
