Suppliers of L - Theanine Powder by Supercritical Carbon Dioxide Extraction.

1. Introduction to Supercritical Carbon Dioxide Extraction

Supercritical carbon dioxide extraction has become a prominent technique in the field of extraction. Carbon dioxide, when in its supercritical state, possesses unique properties that make it an ideal solvent for various substances. It has a relatively low critical temperature (31.1 °C) and pressure (73.8 bar), which allows for the extraction process to be carried out under milder conditions compared to some traditional extraction methods. This is especially important when dealing with heat - sensitive substances like L - theanine.

In the supercritical state, carbon dioxide has the density of a liquid and the diffusivity of a gas. This combination enables it to penetrate the matrix of the raw material effectively and dissolve the target compounds, such as L - theanine, with high efficiency. Moreover, supercritical carbon dioxide is non - flammable, non - toxic, and chemically inert towards many substances. This makes it an environmentally - friendly alternative to other organic solvents that may be hazardous or require complex post - extraction purification steps.
