Initial (0 day) AA was 40.98 mg100−1 g and the data from day 12 onwards is meant for the EC storage only. All fruits stored at ambient were discarded on day 12. NS, *, **, *** indicate non-significant or significant difference at p ≤ 0.05, 0.01 or 0.001, respectively; different letters in a column indicate significant differences at P = 0.05.
