In this study, lowh* values were indicative of browning in apple wedges.
Fig. 3 shows that both alginate and gellan edible coatings
containing N-acetylcysteine as antibrowning agent maintained
apple wedges free from browning during 21 days of
storage, demonstrating that N-acetylcysteine is an effective
antibrowning agent to be incorporated in the formulation
of edible coatings.
