Arils were juiced separately for each of the treatments on each
sampling day using a LiquaFresh juice extractor (Mellerware, Cape
Town, South Africa). Pomegranate juice was used to determine pH
using a pH metre (Crison, Barcelona, Spain), total soluble solids (TSS) expressed as percentage (%) using a digital refractometer
(Atago, Tokyo, Japan). Titratable acidity (TA) measured by titration
with 0.1 mol L1 NaOH to an end-point of pH 8.2 using a Metrohmn
862 compact titrosampler (Herisau, Switzerland). TA was
expressed as gram of per litre of pomegranate juice (g L1) of
citric acid. TSS:TA was calculated based on % ratio. All values are
presented as mean standard deviation (SD).
