While this process is indispensable for developing the apple’s characteristic flavor and vibrant color, it often comes with a trade-off: significant textural degradation, resulting in a mealy and soft fruit that frequently falls short of modern consumer expectations for crispness and firmness.
A recent study aimed to resolve this inherent quality trade-off by investigating an integrated postharvest strategy. Researchers evaluated the sensory profile and consumer acceptance of ‘Annurca’ apples subjected to three different treatments. These included the traditional *melaio* reddening, a 1-methylcyclopropene (MCP) treatment alone—known for its ability to maintain fruit firmness—and a combined treatment of MCP followed by *melaio* reddening (MCP+Melaio).
A large panel of 534 consumers participated in evaluating the apples for overall liking and the intensity of seven key sensory attributes. The results clearly indicated that the integrated ‘MCP+Melaio’ treatment was significantly preferred, with a mean liking score of 6.61, compared to both the traditional ‘Melaio’ treatment (M = 5.91) and the ‘MCP’ alone treatment (M = 5.91). This superior preference was attributed to a well-balanced sensory profile achieved through the combined approach.
The integrated treatment successfully married the high crunchiness and low mealiness typically preserved by MCP treatment with the intense aroma and sweetness developed during the *melaio* phase. Further analysis through consumer segmentation identified four distinct preference clusters. The success of the integrated treatment was largely due to its ability to satisfy the divergent priorities of the two largest segments: “Melaio Fans,” comprising 37% of consumers, and “Texture & Flavor Seekers,” making up 35%. This demonstrates a broad appeal across different consumer preferences.
Ultimately, the findings underscore that combining 1-MCP with traditional postharvest practices creates a synergistic effect. This approach yields a high-quality apple that is texturally superior, aromatically intense, and boasts an extended sensory shelf-life. This scientifically validated and practical solution offers a significant enhancement to the quality and consistency of ‘Annurca’ apple production, focusing on sensory attributes rather than hormonal effects.
