Abstract

This study was conducted to develop purees from pumpkin and sweet-pumpkin. Soluble solids in pumpkins were increased as heating time increase. The maximum yield of puree from sweet-pumpkin marked 78.2% when in prepared at 121$^{\circ}C$ for 60 minutes heating, but puree from pumpkin was 53.2% at 121$^{\circ}C$ for 40 minutes heating. Soluble solid and yield of pumpkin purees were increased with enzyme treatment. but viscosity was deceased remarkably. Hunter's a and b values of puree from sweet-pumpkin were higher than puree from pumpkin, and it was considered due to higher content of carotenoid. Organoleptic qualities of puree from pumpkin and sweet-pumpkin were investigated by 5-point scale and the most effective heating time was 40 minutes at 121$^{\circ}C$.
