title: An economical and efficient technology for the extraction of resveratrol from peanut (Arachis hypogaea) sprouts by multi-stage countercurrent extraction.
abstract: In this paper, an economical and efficient technology for the extraction of resveratrol from peanut sprouts by multi-stage countercurrent extraction (MSCE) was investigated based on the alkaline extraction and acid precipitation method (AEAP). Firstly, the MSCE equipment and operation procedures were designed. Then, the optimal parameters of MSCE were obtained by using single-factor experiments and Box-Behnken design (BBD) as follows: extraction temperature of 46.6 °C, CaO to raw material ratio of 6:100, water to raw material ratio of 8.8:1 and extraction time of 51.7 min. Finally, the performance of MSCE was compared against the single pot extraction (SPE) under optimal conditions. The results demonstrated that MSCE was a time-saving, energy-saving, and cost-saving extraction technology for manufacturing resveratrol from peanut sprouts.
