In the present study, ferulic (FA) and p-coumaric (pCA) acids were extracted from rice straw (Oryza sativa) alkaline black liquor by an aqueous two-phase system (ATPS) based on cloud point of surfactant/copolymer Pluronic F-127 (PF-127). An acid precipitation process was studied as a primary purification step of FA and pCA and next, an extraction of these hydroxycinnamic acids (HAs) using PF-127 in different concentrations (1.1-17.3% w/w) was performed. The results showed that in PF-127 concentration of 9.4% w/w, yield extrac-tions of 75.8% for FA and 74.3% for pCA were achieved. In addition, FA and pCA were concentrated 2.3 and 2.5 -fold, respectively, compared to their original concentrations in the liquor, resulting in a PF-127 gel containing 0.12% w/w HAs. This material will be further investigated for potential applications in the cosmetics industry as an alternative for obtaining high value-added products in a rice straw-based biorefinery. Data availability: Data will be made available on request. (AU) | |
