摘要
Sensory descriptive analysis is one of the most powerful, sophisticated and most extensively used tools in sensory science, which provides a complete description of the sensory characteristics of food products. Considering the economic and time consuming aspects of training assessor panels for descriptive analysis, several novel methodologies for sensory characterization have been developed in the last ten years. These methodologies are less time consuming, more flexible and can be used with semi trained assessors and even consumers, providing sensory maps very close to a classic descriptive analysis with highly trained panels. Novel techniques are based on different approaches: methods based on the evaluation of individual attributes (intensity scales, check-all-that-apply questions or CATA, flash profiling, paired comparisons); methods based on the evaluation of global differences (sorting, projective mapping or Napping (R)); methods based on the comparison with product references (polarized sensory positioning), and based on a free, global evaluation of the individual products (Open-ended questions). This review aims at reviewing theory, implementation, advantages and disadvantages of the novel product profiling techniques developed in the last ten years, discussing recommendations for their application.
