Effects of hot rehydration in the presence of hydrogen peroxide on microbial quality, texture, color, and antioxidant activity of cold-stored intermediate-moisture sun-dried figs
(Institute of Food Technologists, 2005-04)
Pectin methylesterase (PME) causes considerable softening in intermediate-moisture (IM) figs rehydrated at 30°C and cold stored at 28% to 29% moisture content. Rehydration of figs at 80°C for 16 min inactivated PME partially ...
Potential application of hot rehydration alone or in combination with hydrogen peroxide to control pectin methylesterase activity and microbial load in cold-stored intermediate-moisture sun-dried figs
Sun-dried figs contain a considerable amount of pectin methylesterase (PME) activity (22 μM COOH/ min/g). The enzyme causes softening and loss of desired gummy texture in cold-stored intermediate-moisture (IM) sun-dried ...
Degradation kinetics of anthocyanins from sour cherry, pomegranate, and strawberry juices by hydrogen peroxide
Degradations were studied at different hydrogen peroxide (H2O2] concentrations (9.31 to 27.92 mmol. L-1] over a range of 10 ° to 30 °C. Degradation of anthocyanins by H2O2 was described by first-order function. Comparison ...
Effect of hydrogen peroxide on sour cherry anthocyanins
Degradation of sour cherry anthocyanins was studied at different H2O2 concentrations (0.233-11.63 mmol.L-1) over the temperature range of 20-55C. Degradation reaction fitted to a first order kinetic model progressed very ...
