Notes:
Net yield of canned mushrooms during retorting was improved by vacuum hydration. Yield, color, and texture decreased with increased process time at all temperatures. Process-induced changes in all three parameters were modeled as first order reactions. For hydrated mush-rooms, activation energies for yield, color and texture were 16.0 Kcal/mole, 16.2 Kcal/mole, and 31.3 Kcal/mole, respectively. Corresponding values for nonhydrated mushrooms were 15.9 Kcal/mole, 38.4 Kcal/mole, and 38.5 Kcal/mole. Z values for yield, color and texture of hydrated samples were 44.0°C, 43.9°C, and 22.4°C, respectively, and for nonhydrated samples, 44.1°C, 18.7°C, and 18.3°C, respectively, Vacuum hydration caused color and texture to be relatively insensitive to process temperature.
