Cuticular waxes protect fruit by reducing water loss and influencing color. They are a mix of very-long-chain aliphatic and cyclic compounds, varying among fruit species. In blueberries, triterpenoids and β-diketones are most abundant. Cuticular waxes protect fruit by reducing water loss and influencing color.
