In conclusion, our present data indicate that the reduction in
senescence development by Nano-PM treatment, in mushrooms
stored at 4 C, is associated with inhibition of respiratory activity.
The maintenance of integrity of biological membrane structure,
resulting from the decrease in levels of ROS and the improvement
on antioxidant enzymes activity by the treatment is also involved
in senescence retardation in mushrooms. Furthermore, these
nano-packaging materials have the advantages of simple process-
ing and potential to be applied commercially. Nano-PM could
therefore provide an attractive alternative maintain the quality of
stored mushrooms.
