Effects of wax coatings and postharvest storage on sensory quality and aroma volatile composition of ‘Mor’ mandarins

Abstract

The results showed that after harvest there was a progressive decrease in sensory quality of 'Mor' mandarins. It is proposed that observed decreases in contents of sesqui- and monoterpenes and short-chain oxygenated fatty acids may contribute to the decrease in mandarin flavour, whereas increases in the contents of ethanol fermentation metabolites and derivates of fatty acid and amino acid catabolism are most likely involved in causing the enhanced sensation of off-flavours.
