The most effective Cys concentrations for reducing browning
were 0.3 and 0.5 g/100 mL (wb), with minor or no significant
differences between them in L* and a* values, respectively. However,
those samples prepared with the highest Cys concentration
presented slight off-odors, characteristic of sulphur compounds,
as the trays were opened. Therefore, the lower concentration
was selected to optimize the coating formulation. Optimization
implied an increase in the BW content from 20 to 40 g/100 mL
(db) to reduce the yellow color resulting from applying Cys to
artichoke tissue. This coating (SPI + 0.3 g/100 mL Cys) significantly
reduced the enzymatic browning of minimally processed artichoke,
which obtained higher L* and lower a* values than the control
(water dipped) and the 0.3 g/100 mL Cys-treated samples, and also
diminished the yellow color o
