- Abstract
In this study, changes in total phenolic content (TPC) and antioxidant activity (AOA) of polyphenolics from pulp and peel of red radish (Raphanus sativus L.) were investigated during in vitro digestion. Firstly, ultrasound bath-assisted extraction (UBAE) and ultrasound probe-assisted extraction (UPAE) were applied with different ultrasonication time (20, 60, 180, 540 seconds) to determine the extraction method providing the highest TPC and AOA. The TPC and AOA (two methods) were determined by the Folin-Ciocalteu, DPPH and CUPRAC methods, respectively. According to the results, the highest TPC and AOACUPRAC were 41.17±0.70 mg GAE/g dry weight (DW) and 12.67±0.00 mg TE/g DW for pulp and 243.26±5.44 mg GAE/g DW and 89.65±0.48 mg TE/g DW for peel extracts in UBAE, respectively. The bioaccessibilities (%) of extracts from pulp and peel after in vitro digestion process were %54.21±1.94 and %32.20±2.61 for TPC, %66.46±0.40 and %27.89±0.99 for AOACUPRAC and %302.03±28.52 and %80.43±1.03 for AOADPPH, respectively.
