Abstract

In this study, components having antioxidant properties were extracted by microwave assisted homogenization process from artichoke leaves which are considered as a food waste. Antioxidant capacity, total phenolic and total flavonoid content analyzes were applied to the obtained extracts. Extraction yields were determined by proportioning the antioxidant capacity of the extract obtained as a result of the microwave assisted homogenization processes to the those which were obtained by Soxhlet extraction. To achieve the highest extraction yield for the microwave assisted homogenization, the optimum conditions were determined using D-optimal design by ‘desirability’ function approach. According to the optimization results, the highest extraction yield was predicted as 95.91% with an application of 17.13 minutes of homogenization time, 180 W of microwave power and 11200 rpm of homogenization rate. According to the verification tests, there was no statistical difference between the experimental (96.08±0.83%) and the estimated data (95.91%) (P>0.05).
