How product trial changes quality perception of four new processed beef products

The purpose of this paper is the quantitative analysis of the change in quality perception of four new processed beef products from pre to post trial phases. Based on the Total Food Quality Model, differences in pre and post-trial phases were measured using repeated measures technique for cue evaluation, quality evaluation and purchase motive fulfillment. For two of the tested products, trial resulted in a decline of the evaluation of cues, quality and purchase motive fulfillment compared to pre-trial expectations. For these products, positive expectations were created by giving information about ingredients and ways of processing, which were not confirmed during trial. For the other two products, evaluations on key sensory dimensions based on trial exceeded expectations, whereas the other evaluations remained unchanged. Several demographic factors influenced the pattern of results, notably age and gender, which may be due to underlying differences in previous experience. The study gives useful insights for testing of new processed meat products before market introduction.
