This study developed a two-stage organosolv extraction process for the production of diverse components from tea oil fruit hull (TOFH) – a common lignocellulosic byproduct of tea oil processing industry. Results showed that a mild aqueous ethanol organosolv (AEO) extraction isolated 83.8% of tea saponin and 81.5% of tannin from the TOFH. Further, a severe atmospheric glycerol organosolv (AGO) extraction recovered the residual tea saponin and tannin. Meantime, the AGO process removed 40% of the hemicellulose and 35% of the lignin. The solid residual after the two-stage AEO-AGO extraction had a high cellulose hydrolyzability (>95%), much higher than that (only 40%) of one-step AEO extracted solid residual. Structural features of these undissolved solids were characterized by SEM, AFM and FT-IR. The two-stage organosolv extraction showed good potential in biorefining of the agroforestry biomass into value added bioproducts.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
