[Nutritional composition and nutritional claims of Canary Islands banana].

Introduction: Objectives: Canary Islands bananas represent the only native cultivar of Musa spp. present in Spanish territory. Since 2013, it has the Protected Geographical Indication label, which confers an additional value to this fruit. Bananas from the Canary Islands have certain organoleptic properties that make them stand out from among other commonly consumed Musa spp. However, to date, no studies have been reported including an extended nutritional composition of this product. Methods: the present work shows the main nutritional components of bananas from the Canary Islands as determined by different analytical techniques (mainly liquid chromatography, spectroscopy, spectrophotometry, and polarimetry) when at their best in terms of ripeness (grade 6). Moreover, potential nutrition claims relating to their composition were proposed using the current legislation. Results: the fruit's remarkable content, edible portion, in vitamin B6 (0.52 g/100 g), dietary fiber (2.22 g/100 g), potassium (419.9 mg/100 g), and vitamin C (12.35 mg/100 g) should be highlighted. Additionally, these components could appear on nutritional labeling as claims, according to current European regulations. Conclusions: a daily consumption of one Canary Islands banana contributes to the recommended dietary intake of vitamin B6, vitamin C, potassium, and dietary fiber. The high nutritional value of this fruit enhances its presence in the Mediterranean eating pattern, being remarkable as a local product with excellent nutritional properties.
