Extracts

1. Solvent-Based Extraction

Solvent-based extraction methods involve using solvents such as ethanol or butane to dissolve cannabinoids, terpenes, and other desired compounds from the plant material. This process allows for the creation of potent concentrates such as shatter, wax, or oil. It is important to follow safety guidelines and regulations when performing solvent-based extractions due to the flammable nature of some solvents.

2. CO2 Extraction

CO2 extraction utilizes carbon dioxide in a supercritical state to extract cannabinoids and terpenes from the plant material. This method is known for its efficiency and ability to selectively extract desired compounds while minimizing the extraction of unwanted substances. CO2 extraction is commonly used to produce high-quality oils and concentrates.

3. Rosin Pressing

Rosin pressing involves applying heat and pressure to cannabis flower or hash to extract cannabinoids and terpenes without the use of solvents. This method is popular among home-based extract producers due to its simplicity and safety. Rosin pressing can yield flavorful and potent concentrates that retain the natural characteristics of the plant.

Edibles

4. Decarboxylation

Decarboxylation is a process that involves heating cannabis flower or concentrates to activate the cannabinoids present, such as THC and CBD. This step is essential for creating edibles as it converts the non-psychoactive THCA and CBDA into their active forms. Decarboxylation can be achieved by baking the cannabis in an oven at a specific temperature for a certain duration.

5. Infusion

Infusion is the process of incorporating cannabis into edible products by combining it with fats or oils. This can be done through methods such as steeping cannabis in melted butter or oil over low heat, creating infused products like cannabis-infused butter or cooking oil. Infused fats or oils can then be used in various recipes to create a wide range of cannabis-infused edibles.

6. Culinary Techniques

Cannabis can be incorporated into various culinary techniques to create infused dishes and beverages. From baking brownies and cookies to making infused oils for salad dressings, the options are limitless. Utilizing proper dosage control and careful recipe formulation is essential to ensure consistent and safe consumption of cannabis edibles.

Concentrates

7. Hashish Production

Hashish, or hash, is a concentrated form of cannabis that is created by separating the trichomes from the plant material. Traditional methods involve sieving or pressing the resinous trichomes to form solid or sticky blocks of hash. Modern techniques utilize ice water extraction or solvent-based methods to produce high-quality hashish concentrates.

8. Kief Extraction

Kief refers to the resinous trichomes that have been mechanically separated from the cannabis flower. It can be collected using a specialized grinder or through sieving methods. Kief can be consumed as is or further processed into other concentrates such as sift or dry sift.

Post-harvest processing plays a critical role in transforming harvested cannabis plants into extracts, edibles, and concentrates. From solvent-based extractions and CO2 extraction for concentrates to decarboxylation and infusion techniques for edibles, the possibilities are vast. It is essential to understand and adhere to safety guidelines and regulations when performing post-harvest processing methods. By utilizing proper techniques and equipment, cannabis producers can create a diverse range of products that cater to the preferences and needs of consumers.
