C—control protein bar with no powder added, V1—protein bars with 6% addition of freeze-dried powder based on kiwi-pomace, buckwheat and Lacticaseibacillus casei 431^®, V2—protein bars with 6% addition of freeze-dried powder based on kiwi peels Lacticaseibacillus casei 431^®. Means that on the same row do not share a letter (a,b,c) are significantly different, based on Tukey method and 95% confidence.
