2.3.2 Effects of Waxes on Water Reduction from Labeled Areas
Natural waxes on the epidermis play a vital role in retaining moisture in fruit and
vegetables (Kader, 2002). The openings created by laser labeling disrupt the natural waxy
coating on the surface of produce. In this experiment, all nine commercial waxes that were
applied helped in reducing water loss by sealing the etched area. However, significant
differences in the capability of these waxes to prevent water loss were observed. Among all
waxes, three reduced water loss by >80%, with Carnauba 505 resulting in the highest protection
(86% reduction in water loss)
