## 5 Conclusions  
HS-SPME/GC\(\times\)GC-ToFMS allowed us to detect hundreds of instrumental features, among which, a set of 57 compounds potentially related with aroma and/or ripening status of \"Rocha\" pears. Monitorization of such compounds over a four-month storage assay showed that coating application had an impact on their release under DCA storage but not in NA conditions. In the former, coatings decreased the release of \"Rocha\" pear volatiles potentially related with aroma or ripening status, namely, esters and sesquiterpenes, and showed a lower CTs content as compared with the control. The TSS content and color were not affected by coatings. These results indicate that the combination of pectin coatings with DCA storage can delay fruit ripening and prevent SC development, thus, contributing to the preservation of \"Rocha\" pears for longer periods. Impacts observed are mainly attributed to the coating as a gas barrier in the surface of the fruit, since coatings enriched with plant extracts had a similar behavior to PCT coating on measured parameters. **Supplementary Materials:** The following are available online at [[http://www.mdpi.com/2304-8158/9/9/1299/s1](http://www.mdpi.com/2304-8158/9/9/1299/s1)]([http://www.mdpi.com/2304-8158/9/9/1299/s1](http://www.mdpi.com/2304-8158/9/9/1299/s1)), Table S1: Full dataset used for statistics processing of the identified \"Rocha\" pear volatile compounds using HS-SPME/GC\(\times\)GC-ToFMS, including relevant chromatographic data used to assess compounds identification and respective odor descriptors, Figure S1: Dendrograms of the hierarchical clustering analysis (HCA) for previously reported volatile compounds of \"Rocha\" pears at 9, 32, and 134 days of the assay in NA (normal atmosphere) storage conditions.
