The pH values ranged from 2.86 to 4.08 (red raspberry and cherry,
respectively), and the levels of acidity ranged from 0.55 g of citric
acid/100 g in the cherry to 1.88 g of citric acid/100 g in the red
raspberry. With respect to total soluble solids and total sugars, the
blackberry had the lowest levels (10.17 Brix and 4.47%, respectively)
and cherry had the highest levels (18.67 Brix and 13.73%,
respectively). Among the fruits analyzed, the blueberry and the
cherry stand out for presenting the highest levels of total soluble
solids and sugars and the lowest levels of acidity; consequently,
they have the highest ratios of total soluble solids/acid (28.61 to
blueberry and 34.07 to cherry).
