Post extraction purification of terpenes

A method for purifying terpenes, comprising:

• providing cannabis material having a detectable tetrahydrocannabinolic acid (THCA) content;
• adding a solvent to the cannabis material;
• enclosing the cannabis material in a stainless steel filter basket having a pore diameter of between 20-30 microns;
• spinning the filter basket in a centrifuge to separate the cannabis material into tetrahydrocannabinolic acid (THCA) and a high terpene extract (HTE) containing terpenes;
• decarboxilating at least a portion of the tetrahydrocannabinolic acid into tetrahydrocannabinol (THC);
• delivering the high terpene extract into a vacuum oven and reducing pressure to volatilize most of the terpenes in the high terpene extract;
• pumping the volatilized terpenes from the vacuum oven and condensing the volatilized terpenes in a cold trap to yield condensed terpenes;
• cooling the condensed terpenes at a temperature between −50° C. and 0° C. to remove water from the condensed terpenes to yield purified terpenes;
• combining at least a portion of the purified terpenes with the tetrahydrocannabinol in an edible food product.
