Icariin as a Preservative to Maintain the Fruit Quality of Banana During Postharvest Storage

Banana is a tropical fruit with good palatability and multiple health benefits. However, the fruit quality is readily deteriorated during postharvest storage. In this work, icariin was used to treat banana to maintain the fruit quality. NMR spectroscopy was applied to analyze the effect of icariin on the metabolite profiles of banana. It was found that the fruit quality of banana was well maintained after icariin treatment. The data of 1D and 2D NMR spectra revealed the composition of metabolites, whose contents greatly varied during storage. The first principal components included ethanol, acetic acid, saponin b, salsolinol, dopamine, glucose, and linoleic acid. After icariin treatment, the conversion of starch to α-d-glucose and β-d-glucose was delayed, and the production of γ-aminobutyrate, glutamine, and alanine increased. These results indicated that icariin could effectively maintain the fruit quality and delay the senescence of banana.
