Multifunctional Role of Acca sellowiana from Farm Management to Postharvest Life: A Review

Feijoa (Acca sellowiana (O. Berg) Burret syn Feijoa sellowiana Berg) is a monotypic species belonging to the Myrtaceae family. Feijoa is cultivated in different countries, and it is mainly consumed as fresh fruit, due to its attractive nutritional quality, nevertheless, several feijoa-based products have been produced and are available in some niche and local markets. The fruits are not the only edible part of the tree since petals of hermaphrodite showy flowers can also be eaten. Fruits are rich in vitamin C, fiber, potassium, iodine, phosphorus, sugars, and calcium. In addition, a large number of bioactive compounds, with many health-promoting benefits, have been identified. This review is carried out with the aim to provide comprehensive and updated over-view of the state of the art related to the knowledge on feijoa, evaluating the main agronomic, qualitative, and nutraceutical traits of its edible parts. Moreover, the variability in feijoa genetic resources to identify and select promising genotypes useful for breeding programs and the postharvest management of fruit and edible flowers will be discussed. Overall, feijoa has great potential to be considered as a sustainable fruit crop from farm to table.
