dc.descriptionThis manual provides a comprehensive, standardized framework for integrating sensory evaluation into Participatory Variety Selection (PVS), field days, and food product development. Developed by the Pan-Africa Bean Research Alliance (PABRA), it addresses the critical need to align new crop varieties with end-user preferences to enhance adoption rates. The procedures guide stakeholders, including breeders, researchers, and extension workers, in systematically capturing human perceptions of key sensory attributes such as taste, texture, aroma, and appearance. The document outlines the foundational principles of sensory science, including ethical considerations and bias control, with practical guidance suitable for field settings. It details step-by-step protocols for three main categories of sensory tests: affective tests (Paired Preference, Ranking, Acceptability) for measuring consumer liking; discrimination tests (Triangle, Duo-Trio, Tetrad, Attribute Difference) for detecting perceivable differences between varieties; and descriptive analysis (Degree of Difference) for quantifying specific sensory profiles. Each protocol includes clear objectives, required materials, standardized sample preparation, data collection methods, and analysis procedures using XLSTAT software. By offering these practical, adaptable tools, the manual empowers users to make data-informed decisions that bridge the gap between breeder objectives and farmer-consumer demands, ultimately contributing to the development and successful scaling of resilient, market-preferred crop varieties.
