3.2. Effect of cutting styles on TP content in fresh-cut pitaya fruit
As is presented in Fig. 4A, there was a very slow increase in TP
content of whole pitaya fruit with storage time. Fresh-cut
processing significantly (p < 0.05) induced the phenolics accumulation in pitaya fruit in comparison with whole fruit at the first 2 d
of storage. This enhancement of TP content was intensified with
the increase of wounding intensity (p < 0.05). On the second day of
storage, TP contents reached their maximum values, it was
increased by 63, 78, and 90% for slice, half-slice and quarterslice, respectively. While for the whole pitaya fruit, the increment
was only 34%. After 2 d of storage, the fresh-cut pitaya tissues
showed a decline in TP content, but it was still higher than the
whole fruit, where the quarter-slice maintained the highest TP
level
