Sensory characterisation enabled the first classification of dessert bananas

Area of Science:

• Food Science
• Horticulture
• Sensory Analysis

Background:

• Understanding sensory diversity in dessert bananas is crucial for breeding programs.
• Diversifying the banana market requires knowledge of existing cultivars and hybrids.
• Descriptive sensory profiling was employed to evaluate 17 banana varieties.

Purpose of the Study:

• To characterize the sensory profiles of 13 cultivated and 4 triploid hybrid dessert bananas.
• To establish a specific vocabulary for describing banana sensory traits.
• To group banana cultivars based on sensory characteristics for breeding applications.

Main Methods:

• Descriptive sensory profiling of 17 dessert banana cultivars at the eating stage.
• Development of a specific vocabulary to define sensory attributes.
• Statistical analysis to cluster banana cultivars based on sensory data.

Main Results:

• Five distinct sensory clusters were identified among the 17 banana cultivars.
• Clusters differed significantly in sourness, sweetness, flavor, texture, and aroma.
• Cavendish banana (cluster 1) had low sourness and high sweetness/banana flavor.
• Firmness and sourness correlated with rheological pulp firmness and titratable acidity, respectively.

Conclusions:

• Key sensory attributes were identified, effectively grouping dessert banana diversity into five clusters.
• The established clusters and attributes provide valuable data for banana breeding programs.
• Integration with hedonic data will further assist breeders in selecting superior banana hybrids.
