Effects of storage temperature and time on internal quality of satsuma mandarin (Citrus unshiu marc.) by means of E-nose and E-tongue based on two-way MANOVA analysis and random forest

Storage conditions for fresh fruit have been widely investigated, including shelf-life, storage temperature, waxing, and so on. Storage factors, during fresh fruit transportation or marketing, should be considered together and their interactions are also important. In this study, two-way MANOVA was applied to analyze the influence caused by storage time and temperature and also their interaction on the quality parameters. This paper describes the possible application of E-nose and E-tongue to trace the quality status of satsuma mandarin (Citrus unshiu Marc.) during different storage conditions. This technique could be used as a rapid and objective method applicable to routine quality control at any stage of the fruit supply chain.
