Abstract

Methods and processes for efficiently extracting cannabinoids from cannabis are described together with cannabis extracts obtained using such methods. A method may include: preparing a premixture by mixing dried cannabis with an extraction agent; incubating the premixture; and after incubating the premixture, adding a liquid to the premixture to create a liquid mixture and filtering the cannabis from the mixture.

Claims (18)

1. A method of extracting cannabinoids from cannabis, the method comprising:

preparing a premixture by mixing dried cannabis with an extraction agent, wherein the extraction agent is a medium chain triglycerides (MCT) powder;

incubating the premixture; and

after incubating the premixture, adding a liquid to the premixture to create a liquid mixture and filtering the cannabis from the mixture.

2. The method of claim 1 , wherein the liquid is water.

3. The method of claim 1 , further comprising, prior to mixing, pulverizing the cannabis to reduce a particle size of the cannabis.

4. The method of claim 1 , wherein the MCT powder has a fat content that is greater than 65%, a protein level that is greater than 25% and a carbohydrate level of less than one percent.

5. The method of claim 1 , further comprising:

heating the liquid mixture to evaporate the liquid and produce a cannabis extract.

6. The method of claim 5 , wherein the cannabis extract has a moisture content of one percent or less.

7. The method of claim 5 , wherein heating the liquid mixture to evaporate the liquid comprises heating the liquid mixture at a temperature sufficient to decarboxylate.

8. The method of claim 1 , wherein incubating comprises storing the premixture for between two and fifteen days.

9. The method of claim 1 , further comprising, prior to incubating:

vacuum sealing the premixture.

10. The method of claim 1 , further comprising:

after filtering the cannabis, further filtering the liquid mixture to clarify the liquid mixture.

11. The method of claim 1 , further comprising, prior to preparing the premixture:

decarboxylating the cannabis.
