Abstract:
A preparation method for an industrial hemp oil. The method comprises the following steps: drying industrial hemp at a high temperature, then extracting same with supercritical carbon dioxide to obtain a concrete, then subjecting the concrete to winterization and dewaxing and molecular distillation to remove impurities, and finally performing preparative chromatography to obtain a zero-THC industrial hemp extract. In accordance with the above method for preparing an industrial hemp extract, a THC-free industrial hemp extract can be obtained without a decoloration step for removing chlorophyll; and the zero-THC industrial hemp oil may be further subjected to secondary preparation to separately obtain an industrial hemp oil rich in CBDV and an industrial hemp oil rich in CBD.
