Table 3: pH and total soluble solids of apple cubes before and after VI. value than 0.14. The exceptions are cultivars: Lobo, Red Jonaprice, Shampion, and Topaz. In the case of the soluble solids content, a difference greater than 0.99 was recorded for the following cultivars: Boskop, Cortland, Golden Delicious, and Red Jonaprice. Therefore, it seems that the apple impregnation process could cause changes in taste and, depending on their further use, should be subjected to sensory evaluation.
