Extraction & Purification
There are different ways to extract the bioactive compounds from the grape seeds. The most popular and widely used method is by solvent extraction, solvents such as ethanol and water. The other method is supercritical fluid extraction, which uses supercritical carbon dioxide. This method is comparatively more environment friendly and cost higher, but it makes the higher quality product because it can extract the desired compounds without leaving harmful residues. After the compounds are extracted, purification steps are designed to remove impurities such as residual solvents, impurities and other unwanted substances. This makes the product more concentrated and more pure.
