Using pressure to force changes between liquid, solid, and gas phases.

DECOCTION
Extracting a chemical by boiling plant material, which may include stems, roots, bark, and bulbs.

DESICCATION/DRYING
Allowing liquid components to evaporate from a substance at room temperature.

DETERPENATION
Using steam or water to remove terpenes (fragrant compounds made from carbon and hydrogen).

DISTILLATION, EXPRESSION or EXTRACTION
Capturing water vapor from a boiling mixture to separate a component that evaporates easily.

FILTRATION and PURIFICATION (ultra-filtration, dialysis, crystallization, ion exchange)
Ultra-Filtration: Using pressure or density to force a material through a membrane to remove solids and/or large molecules.
Dialysis: Separating molecules by the difference in how quickly they pass through a membrane.
Crystallization: Separating a liquid by creating a solid crystal from a component of the liquid.
Ion Exchange: Replacing a charged molecule with another molecule that has the same charge.

FREEZING
Turning a liquid into a solid by decreasing the temperature below the material’s freezing point.

GRINDING
Using a mechanical device, such as a grinder or mill, to decrease the size of particles.

INFUSION
Extracting compounds from plant material by allowing it to soak for an extended period of time, typically in water, oil, or alcohol.

LYOPHILIZATION
Freeze drying.

MACERATION
Softening or becoming softened by soaking in a liquid.

MICROWAVE
Using microwaves and gravity to separate materials like essential oils from a plant.

PERCOLATION
Filtering fluids through porous materials.

ROASTING
Using hot air to heat material evenly on all sides with an open flame, oven, or other heat source.

SETTLING AND DECANTING
Allowing a mixture to settle and separate by gravity, then pouring off one of the components and leaving the other behind.

SIFTING
Separating and retaining the coarse parts of something with a sieve.

SQUEEZING
Compressing via balanced inward ("pushing") forces to different points on a material.

STERILIZATION WITH THERMAL
Removing microbes from a material by exposing it to flowing or pressurized steam.

ULTRASOUND
Agitating a material using soundwaves to combine materials or remove a material.

VACUUM
Removing oil from a plant by breaking it in small pieces, cooling to low temperature, and exposing to vacuum and nitrogen gas.

Allowed Chemical Processes

ADDITION
Rearranging the units of a polymer (large molecule made of repeating units) so that it can bind with other molecules.

ALKYLATION
Replacing a hydrogen molecule with a group of molecules containing carbon and hydrogen.

AMIDATION
Adding a molecule containing carbon, hydrogen, and nitrogen to a chain of amino acids (the building blocks of proteins).

CALCINATION
Applying heat and removing air to break chemical bonds in solid materials like minerals.

CARBONIZATION
Heating plant oil or resin without air to leave behind solid carbon.

CONDENSATION
Forming a polymer by combining two molecules and ejecting a smaller molecule, usually water, an alcohol, or an acid.

ESTERIFICATION / TRANS-ESTERIFICATION / INTER-ESTERIFICATION
Esterification: Reacting an alcohol with an acid to produce an ester (a carbon and oxygen containing compound) and water.
Transesterification: Exchanging the carbon containing group of an ester with the carbon containing group of an alcohol.
Interestherification: Adding an enzyme (proteins that speed up chemical reactions) to an oil to rearrange the order of a fat molecule

ETHERIFICATION
Dehydrating an alcohol to form a molecule consisting of oxygen attached to two carbons.
