The influence of 0.3% CaCl2 added to irrigation water on mushroom tyrosinase activity and postharvest browning was examined. Calcium concentration of mushrooms was significantly increased with the addition CaCl2 to irrigation water but had no effect on inherent tyrosinase activity but reduced postharvest browning. The CaCl2 had even more pronounced improvement in shelf life as indicated by reduced browning following a standard bruising treatment. Transmission electron micrographs indicate that increased levels of calcium in mushrooms irrigated with CaCl2 may have decreased browning by increasing vacuolar membrane integrity; thereby reducing the opportunity for tyrosinase to react with its substrates.
