Abstract: Fruit and vinegar dressings are seasoned mixture usually used as stuffing in foods. Quality characteristics and antioxidant potentials of fruit and vinegar dressings prepared by adding lentil were investigated and compared with those of commercial products. The four dressing samples were named as D-1: fruit dressing purchased from a local store in Daegu, Korea; D-2: grapefruit-sugaring dressing prepared in the present study; D-3: vinegar dressing purchased from the local store in Daegu, Korea; D-4: pineapple-vinegar dressing prepared in the present study. The pH and titratable acidity in all samples ranged from 2.9 to 4.6 and from 0.6 to 1.2%, respectively. The crude protein content was 2.29% for D-2 and 4.03% for D-4, while was not detected in commercial dressing samples, D-1 and D-3. The D-4 sample exhibited the higher levels of Ca (215.40 mg/kg), K (1,105.83 mg/kg), Mg (233.63 mg/kg) and Fe (13.78 mg/kg). The content of total amino acid in D-3 and D-4 samples were 8.269 and 3.419 mg/mL, respectively. The highest content of total phenols (191.13 µg GAE/mL) and DPPH radical scavenging activity (93.69%, Inhibition) were observed in D-4. The results of this study indicated that use of lentil could increase the quality and antioxidant potentials of fruit and vinegar dressings.
