Effect of an inhibitor of ethylene action, 1-methylcyclopropene (1-MCP), on sensory qualities of apple fruit of 15 common cultivars of Latvia was evaluated in this study. Taste, aroma, sourness, sweetness, juiciness and colour change of control and 1-MCP-treated apple fruit before and after six and nine months of storage were compared using two different methods of sensory evaluation. The evaluated parameters significantly changed during storage, but the results suggest that treatment with 1-MCP did not lead to significant change in sensory qualities of fruits. Experts admitted that treated fruit were juicier and had more distinctive colour even after nine months of storage, although they were slightly more sour than non-treated samples. However, control samples of all apple cultivars were somewhat tastier and sweeter than were 1-MCP-treated fruits.

Key words: apple fruit, 1-methylcyclopropene, sensory evaluation.
