(n = 3)

Initial (0 day) TA value was 0.37% 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 ≤ 0.01 or 0.001, respectively; different letters in a column indicate significant differences at P = 0.001.
