AB The effect of beeswax (BW) content of hydroxypropyl methylcellulose (HPMC)eBW edible coatings onstand-alone film properties and on postharvest quality of coated ‘Angeleno’ plums was studied. Thecoatings contained BWat 4 lipid content levels (0, 20, 40 and 60 g/100 g, dry basis). Coated and uncoatedplums were stored 4 weeks at 1  C and transferred to 20  C for 1e3 weeks. Addition of BW to the HPMCfilm matrix reduced film mechanical resistance and oxygen barrier, and improved film moisture barrier.Film mechanical properties showed a good fit with an exponential and/or linear model that couldprovide a useful tool to predict mechanical properties with others HPMCeBW composition mixtures.Coatings with BW reduced plum weight loss compared to HPMC-based coatings with no BW. Plumweight loss decreased as BW content increased from 20 to 40 g/100 g, but above 40 g/100 g BW content,weight loss was not further reduced. Whereas, water vapor permeability of stand-alone films decreasedsignificantly as BW content increased to 60 g/100 g. Coatings reduced plum softening and bleeding, withthose with lower BW content being more effective, which could be related to the ability of coatings tocreate a modified atmosphere in the fruit. Flavor was not affected by coating application. Results indicatethat HPMCeBW coatings with 20 g/100 g BW would provide the best compromise to extend shelf life of‘Angeleno’ plums.
