Pressurised hot water extraction with on-line particle formation by supercritical fluid technology

► Pressurised hot water extraction is combined with supercritical carbon dioxide to dry extracts. ► The WEPO process stands for water extraction and particle formation on-line. ► The WEPO process: from plants to a dray powder of antioxidant extract in one step. ► The drying power of the WEPO process is comparable to freeze-drying.
