Abstract
Seven typologies of melon belonging to Inodorus and Cantalupensis horticultural groups have been assayed in relation to their sensory and physical–chemical characteristics. Sensory analysis has been performed by means of a descriptive profiling based on objective scales and a trained panel. Multivariate analysis was applied to the individual results associated with the attributes of color, firmness, juiciness, sweetness, acidity, fibrosity and seven different aromas. Accuracy of the panel members and validity of the method were confirmed by the correlation between sensory scores and physical–chemical rates of firmness, juiciness, º Brix and pH. Relationships between sensory parameters and consumer preferences were also identified, resulting in concrete quality marks: high sweetness and juiciness, yellow flesh, moderate acidity and aromas of cucumber, watermelon, pineapple and peach. Additionally, the consumer’s internal map of preferences was developed in order to guide future genetic improvement programs.

Appendix: Practical applications
The sensory protocol for melon established herein has been demonstrated as being effective, efficient and useful for horticultural and seed companies. Effective, since it provides for the first time a concrete sensory profile of several melon market classes. Efficient, because it gives superior information at a low cost when compared to physical–chemical methods. Useful, as it broadens knowledge of human perception of melon sensory attributes and their relative contribution to the overall judgment of quality. This link between sensory attributes and consumer preferences makes out of this protocol a key tool to define selection criteria within breeding programs, ensuring success of enhanced products among consumers.
