A high-protein bar incorporating mealworm powder was developed. The impact of explicit and implicit frame formation on the acceptance and sensory characteristics of this target bar was investigated by comparing it with four commercial protein bars for a total of 275 consumers. To construct the explicit frame, consumers watched a video clip about each frame (environment/nutrition/meal replacement) just before the evaluation. In the no-explicit-frame group, five protein bars were evaluated without video priming. The control group tasted the target sample only without any information. The implicit framework formed during the progress of exposure to various protein bar samples had a greater influence than explicit cues on the acceptance of the target. Promoting the nutritional and environmental merits of edible insects was not sufficient to improve the acceptability of the insect-incorporated protein bar. The liking decreased significantly with the inclusion of the commercial samples during the progress of sequential monadic serving.
