The invention discloses an efficient separation and purification method of MLnM type medium-chain and long-chain
triglyceride, and belongs to the technical field of separation and purification. The efficient separation and purification method comprises the following steps: S1, preparing a crude product; s2, mixing the crude product with an adsorbent for static adsorption; and S3, performing
column chromatography elution on the static adsorption product, and performing dynamic
chromatography to separate the MLnM type
triglyceride. According to the efficient separation and purification method of the MLnM type medium-long-chain
triglyceride, a neutral aluminum
oxide static adsorption and dynamic
column chromatography coupling process is adopted, the purity of the MLnM type triglyceride can be greatly improved and is far higher than that of other adsorbents, the whole process steps are clear, the steps of
raw material preparation, static adsorption, dynamic
chromatography and the like are included, and the method is suitable for industrial production. The operation process is easy for standardized and large-scale production, and does not need to depend on complex equipment such as molecular
distillation, supercritical CO2 extraction and the like.
