Apple pieces treated with 0.3% and 0.1% Cys aqueous solutions showed a pinkish-red appearance, whereas this effect was not shown when similar levels of Cys were incorporated into the WPC–BW-based coating.
Coating application did not reduces weight loss in fresh-cut apples, probably due to the high relative humidity of the product.
A sensory panel was able to discriminate between samples coated with WPC–Cys and
