A method for preparing a cannabinoid concentrate, comprising the steps of:
- providing a lipid extract containing cannabinoid acids in an amount of at least 20% by weight on total cannabinoids weight;
- subjecting said lipid extract to a vacuum distillation, wherein said vacuum distillation is carried out at a temperature in the range from 120° C. to 260° C. and at a pressure below 0.04 mbar, avoiding a decarboxylation step of the cannabinoid acids;
- and
- separating from said vacuum distillation a distillate containing the cannabinoid concentrate, wherein the cannabinoid acids content of the cannabinoid concentrate is at least 20% by weight on total cannabinoids weight and wherein the cannabinoid concentrate comprises less than 1 ppm of organic solvent selected from the group consisting of acetone, benzene, butane, chloroform, cyclohexane, dichloromethane, ethanol, ethyl acetate, ethylbenzene, heptane, hexane, isobutane, isopropanol, methanol, pentane, propane, toluene, m-xylene, o-xylene, p-xylene or a mixture thereof.
