Abstract Cold-induced sweetening (CIS), which occurs when potatoes stored at low temperature for long-term, causes changes in flavor and unwanted dark colors in fried and roasted potatoes. The culprit for CIS is an enzyme called invertase. Five potato cultivars A (FD3-10), B (FD3-9), C (TPS-9801), D (393574-61) and E (Laal-e-Faisal) were investigated for invertase activity at cold storage. The...
