Abstract

Sensory analysis is a scientific method used to measure, analyze and interpret reactions related to product characteristics such as perceived through the senses, responding to much more than simply preference for one product over another. Specific scientific methods have been developed to measure or estimate objectively, accurately and reproducibility human responses to stimuli that they are submitted. Descriptive tests, which are part of sensory analysis, require careful control of possible variables that can affect the results, such as test environment, sample storage, skin conditions of the panelists, product attributes selection and training. The training philosophy is to provide the same sensory experience to panelists through the use of a wide variety of references samples, concepts, terminology, protocols, and scales, which is essential to establish a common frame of reference, whose purpose is to remove the\"subjective\" connotation from this sensory methodology. By using this methodology, we achieved consistente, similar and with small standard deviations answers, after three months of training with the panel, which was able to distinguish seven moisturizers commercial products into the studied attributes (AU)
