Reduction of greening in Atlantic and Cadima potatoes.

The effects of light on greening and visual external quality of potato cv. Atlantic and Cadima tubers which were coated with various protective coating solutions (3% sweet potato flour, 3% tapioca flour, 3% arrowroot flour, 3% gelatin, 1.5% Semperfresh, Ausgloss) and low-density polyethylene bag were investigated. Ausgloss and gelatin solution coating reduced the degree of greening and hence improved tuber quality when they were placed under constant light. The beneficial effect of modified atmosphere packaging in reducing greening was not observed. The maturity of the tubers based on harvesting date seemed to have no effects on the development of greening in either cultivar, but the degree of greening was more severe in Atlantic than in Cadima. The contents of alpha -solanine, alpha -chaconine and total glycoalkaloids were also determined and found to be well below the 200 mg/kg FW limit for safe human consumption. No apparent trends were observed when comparing potatoes harvested at different

maturity and stored under light after different coating treatments.
