Acceptance and Preference Testing

All interested parties are invited to particpate in the development of a proposed new ASTM standard that will be useful for anyone in the sensory evaluation field who needs to collect, analyze, interpret and review results from two-sample acceptance and preference tests.

WK22268, Guide for Two-Sample Acceptance and Preference Testing with Consumers, is being developed by Subcommittee E18.04 on Fundamentals of Sensory, part of ASTM International Committee E18 on Sensory Evaluation.

“Acceptance and preference are key measures used by sensory and consumer professionals for evaluating products in all stages of development,” says Lori Rothman, section manager, consumer science, Kraft Foods, and an E18 member. “Both measures can provide information on a product’s hedonic status, but acceptance and preference provide different information and should not be considered interchangeable.”

According to Rothman, WK22268 will cover fundamental issues to consider in a two sample liking or preference test.

“The range of issues, from setting up the hypotheses to be tested, the risks and interpreting results from using these measures in consumer product tests and why they may not agree will be covered in WK22268,” says Rothman, who also notes that the proposed standard will prove helpful to both new and established users of acceptance and preference testing.
