Determination of impregnation values of some postharvest apple kinds under different vacuum pressures

In this study, Golden Delicious, Starking Delicious and Granny Smith kind apples were observed under different vacuum pressures. The effect of vacuum pressure and vacuum period was investigated and results were evaluated graphically and statistically. The biggest X (Impregnation liquid fraction) values were determined in Starking Delicious(11.02), and the lowest values were determined in Golden(3.74) and Granny(4.31) Apples. According to observations suitable vacuum pressures for each one was evaluated. For Golden, 50 kPa and 60 kPa(R2≥0.99), Starking 50 kPa(R2≥0.98) and Granny 60 kPa (R2≥0.98) was determined. For each of these apples working under these vacuum pressures would give more favorable results.
