Consumer perception of foods processed by emerging technologies has been scarcely studied. This study aimed to evaluate the perception of vegan and non-vegan consumers regarding probiotic almond-fermented beverages processed by ultrasound using the packaging of the prod- ucts (pasteurized/conventional, processed by ultrasound, and processed by ultrasound with a claim on the label). A “Check All That Apply” test with emojis and the Food Technology Neophobia scale were used. The “processed by ultrasound” information did not impact the purchase intention and the perception of healthiness, safety, nutrition, environmental impact, flavor, texture, and price of the products. The claim inclusion increased the perceived acceptability and purchase intention and improved the emotional profile. The vegan consumers showed a more positive perception of ultra- sound processing, resulting in increased perceived acceptability, higher citation frequency of posi- tive emoji, and lower sums for the neophobia scale. Vegan and non-vegan consumers agreed that the most important attributes for consumer acceptance are almond aroma, flavor, and consistency. In conclusion, the “processed by ultrasound” information did not negatively impact the acceptabil- ity and emotional profile of probiotic almond-fermented beverages, and using a claim on the label may improve consumer perception of the products.
