Název v původním jazyce

Effect of heat treatment on re-solubility of potato proteins isolated from industrial potato fruit juice

Popis výsledku v původním jazyce

The contribution deals with thermal stability and re-solubility of potato tuber proteins isolated by ethanol precipitation from industrial potato fruit juice. The protein isolate was exposed to the temperatures ranging from 25°C to 70°C. Patatin, the tuber protein with a high nutritious value, was detected by SDS-PAGE in the range of 39-43 kDa. Patatin was evaluated as thermal sensitive - temperatures above 30°C caused its strong insolubility. Potato protease inhibitors were detected in the region from4.3 to 24 kDa. Thermal stability of potato protease inhibitors (region from 25 to 14 kDa) was higher, although the temperature above 45°C caused denaturation and insolubility of most of the protease inhibitors. Extremly thermo-stable was potato carboxypeptidase inhibitor with molecular weight of 4.3 kDa that remained soluble even after having been exposed to the highest temperatures.
