Glycoalkaloid content of potatoes sold in Czechia.

Glycoalkaloid levels in different cultivars collected from three regions were monitored during two years. With the exception of Karin, one of the most widely grown cultivar in the Czech Republic, none of the cultivars used for human consumption exceeded the levels considered safe. The average of total glycoalkaloids content for tested cultivars ranged from 31 to 166 mg/kg fresh weight. There were no significant differences between glycoalkaloid levels in tubers from different regions. Attention was paid to the adequate sampling procedure.
