but there is a need for systematic data on the effect of factors such as pH, preservatives and packaging material on color stability of minimally processed vegetables. Therefore, in the present study pumpkin purees of pH 4.00 and 5.00 were formulated containing KS, AA and their mixture. The goal of this research was to investigate the effect of type of packaging, pH and presence of previously mentioned additives on color of the purees throughout the storage at 25 C during 6 weeks.
