摘要：In this study, the ultrasonic-assisted extraction for phenolic compound extraction
from the carob pulp (Ceratonia siliqua L.) was applied. The Box-Behnken design
and response surface methodology (RSM) were used to study and optimize the
effect of processing variables, acetone concentration (60-80%), extraction
amplitude (30-100%) and extraction time (10-60 min) on the total phenolic
content (TPC) and the antioxidant activity. The optimal values for the TPC yield
and for the antioxidant activity were at 59.30% and 61.70% acetone concentration,
85.86% and 90.12% extraction amplitude, and 53.24 min and 56.82 min of
extraction time, respectively. The experimental values were in accordance with
those predicted by the model, which indicated the suitability of response surface
methodology in optimizing the antioxidants extraction from carob pulp by
ultrasonic-assisted extraction.
