Abstract:

Dipping treatment of aqueous solutions of methyl jasmonate (MJ) at different levels (0, 0.5 and 1 mM) was investigated as a possible strategy for postharvest button mushroom (Agaricus bisporus) quality enhancement during storage. Changes in colour, total soluble protein contents, polyphenol oxidase (PPO, EC 1.10.3.1), peroxidase (POD, EC 1.11.1.7) and malondialdehyde (MDA) contents, H₂O₂ and O₂^{• –} activities and microorganisms such as aerobic mesophiles, psychrotrophs, Pseudomonas spp. and yeasts and molds were studied as quality markers. As compared to control, methyl jasmonate resulted in better colour maintenance during storage by decreasing the activities of PPO and POD and also reduced the accumulation of MDA, H₂O₂ and O₂^{• –} during subsequent storage. Moreover, methyl jasmonate significantly reduced the microbial loads as compared to control. Our results suggest that exogenous application of methyl jasmonate at 0.5 mM concentration as dipping treatment can serve as promising tool for quality enhancement of button mushroom during storage.
