Skin spotting situation at retail level in Australian Avocados

Abstract

Skin spotting (SS) on avocado fruit is evident as blackened areas of <1 mm diameter with well-defined margins. Previous preliminary consumer research indicated that Australian consumers may be concerned by SS on avocado fruit displayed at retail level. A better understanding of SS and its likely commercial impact was sought. Findings for cultivar 'Hass' avocado from retail surveys conducted over two years were collated. The surveys were carried out in various retailer outlets in the capital cities of New South Wales (Sydney), Queensland (Brisbane), Victoria (Melbourne), and Western Australia (Perth). Marked differences in SS severity were recorded across the States and also across months within one State. Differences in SS levels between types of retail outlet stores were also statistically significant. The data are discussed in terms of possible reasons for the variation observed.
