What is Organic Rosemary Antioxidant CO2 Extract?

Supercritical CO2 Extraction: This method of extraction separates bio-active substances such as antioxidants, natural flavors, and essential oils from plant matter. Carbon Dioxide, the gas that gives all the sparkle to sparkling drinks, is a GRAS-approved solvent for lipophilic molecules. The high-pressure process works without the stress of high temperatures and under the exclusion of oxygen which preserves valuable plant ingredients. CO2 acts like a gas at standard temperature and pressure or as a solid (dry ice) when frozen. If the temperature and pressure are both increased to be at or above the critical point for CO2, the CO2 adopts properties between a gas and a liquid – it expands to fill a container like a gas, but has the density of a liquid. The CO2 extraction process is non-toxic and non-flammable. The CO2 simply evaporates off into the air after extraction – or can be recycled by condensation in a cold recovery vessel.
