چکیده    The effect of postharvest uv-c irradiation on phenolic compounds accumulation was investigated in berries of ‘rishbaba’ table grape (vitis vinifera cv. rishbaba). grape clusters were harvested at mature stage and irradiated with uv-c using fluorescent germicidal lamp (30 w, 90 cm) with a peak emission at 254 nm for 0 (control), 5 and 10 min. uv-c treatment had significant effect on individual phenolic compounds. catechin, epicatechin, procyanidin b2, quercetin 3-galactoside, quercetin 3-rhamnoside, chlorogenic acid and total polyphenols increased with uv-c dosage, but procyanidin b1 and cyanidin 3-galactoside decreased. positive correlation was observed between uv-c treatment and individual phenolics except procyanidin b1 and cyanidin 3-galactoside. in conclusion, uv-c irradiation increased phenolic compounds of ‘rishbaba’ table grape and its nutritional value.
