3.4. MDA contents and relative electrolyte leakage
MDA content increased rapidly during the
first 6 days of storage
and thereafter continuously increased throughout storage
(Fig. 2A). Mushrooms packed with Nano-PM maintained a
significantly lower MDA content than the control. At the end of
storage, the MDA content of Nano-PM packed mushrooms was
2.22 mol kg1, which was 29.3% lower than that in Normal-PM. The
relative electrolyte leakage of F. velutipes gradually increased
during the whole storage (Fig. 2B). The mushrooms packed in
Normal-PM had a higher relative electrolyte leakage after 15 days
of storage compared with control samples (P < 0.05).
