Effect of AITC treatment on TSS and TA contents of mulberry fruit
Different cultivars within a species could vary greatly in fruit
quality. TSS is a fundamental quality in the assessment of quality
and marketability of various fruit commodities during storage (Oz
and Ulukanli, 2014). Initial amounts of TSS content of mulberry (M.
alba, cv. Dashi) fruit in the present work was about 10.0%, that were
higher than those reported by Iqbal et al. (2010) (7.42%), but lower
than those of Oz and Ulukanli (2014) (23.1%). As shown in Fig. 4A,
TSS contents of both the control and AITC treated samples
decreased with the storage time. TSS contents of fruit treated with
AITC at 0 (control), 5 and 15 mL L1 decreased from the initial 10.0%
to 7.60%, 9.20% and 9.27% on day 15, respectively. Higher TSS
contents were observed in AITC-treated mulberry fruit in
comparison with that of the control. A similar
finding was
reported by Wang and Chen (2010) that AITC treatment could
maintain higher sugar contents in blueberry fruit during storage.
