color. Results were expressed as percentage of citric acid. The
previous homogenized filtrate was used to measure pH values
which were recorded in a digital pH meter (HORIBA, F-51, Kyoto,
Japan). For SSC, 20 g of fresh flesh were blended separately in
100 mL of distilled water and filtered through layers of cheesecloth.
Some drops of the filtered solution were placed in a hand-held
ATAGO refractometer (Atago, Pocket PAL-1, Tokyo, Japan) and
readings reported as percentage of soluble solids.
