BACKGROUND: The vegan food market is one of the fastest growing markets worldwide for ethical, environmental, and health reasons. However, vegan food is still relatively unfamiliar to Korean consumers. Their liking for vegan burger patties is in the early phase of development; thus, it is necessary to place the patties in an appropriate context or ‘frame’. RESULTS: We investigated consumer (n = 269) liking for vegan patty under different frame conditions. The implicit frame condition was manipulated by evaluating a target sample along with four other vegan or meat samples. Consumers were further divided into two explicit groups that were exposed to or not exposed to a video clip on ethical food consumption before evaluating the samples. A control group evaluated the target sample only. The results showed that the implicit frame formed during the sample evaluation had a stronger influence than the explicit frame created by the video clip. Perceived familiarity with the target vegan patty drastically decreased when evaluated with other meat samples and negatively influenced the liking for it. CONCLUSION: The findings show that the type of samples evaluated sequentially together with the target vegan burger patty within the same session had a greater effect on the target sample than the information provided explicitly. To introduce the target vegan burger patty effectively to consumers who are relatively new to the vegan food product category such as Koreans, it is suggested that the product should be positioned under the category of vegan foods rather than the category of conventional burger patties.
