Acceptance Testing Sensory Evaluation of Food

Abstract

An alternative to choice procedures for assessing the consumer appeal of foods is to use a rating scale for the degree of liking or disliking, otherwise known as acceptability scaling or acceptance testing. This chapter illustrates procedures for acceptability scaling, starting with the traditional 9-point hedonic scale in widespread use. Alternative types of acceptance scales are shown. The just-about-right (JAR) scale is illustrated and its statistical analyses are discussed.
