Opis: Sensory Evaluation Techniques - Thomas Carr, Gail Vance Civille

This new edition of a bestseller covers all phases of performing sensory evaluation studies, from listing the steps involved in a sensory evaluation project to presenting advanced statistical methods. Like its predecessors, Sensory Evaluation Techniques, Fifth Edition gives a clear and concise presentation of practical solutions, accepted methods, standard practices, and some advanced techniques. The fifth edition is comprehensively reorganized, revised, and updated. Key highlights of this book include: * A more intuitive organization * Statistical methods adapted to suit a more basic consumer methodology * Rearranged material to reflect advances in Internet testing * New time-intensity testing methods * New chapters on advanced sensory processes, quality control testing, advertising claims, and business challenges * New material on mapping and sorting, graph theory, multidimensional scaling, and flash profiling techniques * Explanations of theories of integrity, amplitude, and balance and blend * Updated appendices for spectrum method scales * Updated references Sensory Evaluation Techniques remains a relevant and flexible resource, providing how-to information for a wide variety of users in industry, government, and academia who need the most current information to conduct effective sensory evaluation and interpretations of results. It also supplies students with the necessary theoretical background in sensory evaluation methods, applications, and implementations.Introduction to Sensory Techniques Introduction Development of Sensory Testing Human Subjects as Instruments Conducting a Sensory Study References Sensory Attributes and the Way We Perceive Them Introduction Sensory Attributes Human Senses Perception at Threshold and Above References Controls for Test Room, Products, and Panel Introduction Environmental Controls Product Controls Panelist Controls References Factors Influencing Sensory Verdicts Introduction Physiological Factors Psychological Factors Poor Physical Condition References Measuring Responses Introduction Psychophysical Theory Classification Grading Ranking Scaling References Guidelines for Choice of Technique Introduction Define the Project Objective Define the Test Objective Integrate Project Objective and Test Objectives to Construct Test Design Reference Overall Difference Tests: Does a Sensory Difference Exist between Samples?
