Carboxymethyl chitosan-based coatings loaded with glutathione extend the shelf-life of harvested enoki mushrooms (Flammulina velutipes)

Carboxymethyl chitosan has anti-bacterial activity and good coating forming ability, and glutathione has antioxidant and browning-inhibiting capacity. This study investigated the effects of carboxymethyl chitosan-based coatings alone (1% carboxymethyl chitosan) or loaded with glutathione (1% carboxy...

Description
Summary:Carboxymethyl chitosan has anti-bacterial activity and good coating forming ability, and glutathione has antioxidant and browning-inhibiting capacity. This study investigated the effects of carboxymethyl chitosan-based coatings alone (1% carboxymethyl chitosan) or loaded with glutathione (1% carboxymethyl chitosan + 0.2% glutathione) on the refrigeration of harvested enoki mushrooms (Flammulina velutipes) for preservation. Compared with the control group, all the treated samples exhibited decreased total viable count, respiratory rate, weight loss and browning degree and increased soluble solid content and sensory overall likeness after 12 days of refrigeration (P
