Abstract
In this study, fruits of the apple cv. ‘Golden Delicious’ (Malus_/domestica Borkh.) were subjected to post-harvest calcium infiltration under vacuum. Research has been performed in two harvest years. In the first year, ‘Golden Delicious’ fruit were infiltrated with 0, 2, 4 or 5% CaCl2 solutions and stored at 0 °C for up to 6 months. In the first year of harvest, apples were kept under -53.3 kPa and -66.6 kPa vacuum pressures for 2 and 2.5 minutes. In the second harvest year, ‘Golden Delicious’ apples were infiltrated with 0, 2, 4 CaCl2 solutions and stored at 0 °C for up to 6 months. In that harvest year, apples were investigated under -26.6 kPa and -53.3 kPa vacuum pressure for 2.5 min. and submerged into solution for 1 min. Calcium chloride absorbed apples were investigated for surface hardness, water soluble matter criteria and compared with untreated apples. The highest calcium infiltration was determined under -66.6 kPa vacuum pressure in 5% CaCl2 solution but also the highest harm was also seen under the same conditions. The most suitable vacuum pressure for calcium infiltration and pulp hardness was found to be -53.3 kPa. The best Ca quantity and pulp hardness was obtained in 4% CaCl2 solution so that the pulp hardness values after 6 months storage were nearly same or higher than control fruits.
