The influence of reconditioning effectiveness of potato tubers of selected cultivars on colour of French fries
Abstract.

The experiment was carried out on five potato cultivars: ‘Oman’, ‘Gracja’, ‘Tajfun’, ‘Niagara’, ‘Syrena’. The tubers were stored at 3, 5 and 8°C and reconditioned at 20°C for 14 days. The investigations were carried out in two periods: after harvest and seven months of storage. Reducing sugar contents were determined after harvest and seven months of storage at 3, 5 and 8°C and reconditioned. Colours of French fries were estimated using objective method in system CIE L*a*b*. Low content of reducing sugar after harvest and storage at 8°C were observed in all tested potato tubers of all cultivars. High efficiency and effectiveness of the reconditioning process were observed in tubers of ‘Oman’ cultivar. Potatoes of that cultivar can be stored at low temperatures using reconditioning. Colours of French fries made from ‘Oman’ cultivar after reconditioning were appropriate. Potato cultivar ‘Gracja’ can be stored at 5°C without reconditioning. The colours of French fries made from this cultivar was appropriate.
