The Consumer Is Always Right: Research Needs on Sensory Perception of Mushroom-Enriched Meat Products

Currently, consumers demand healthier and more sustainable foods, but it must be considered that sensory characteristics directly drive acceptability and preference. The objective of this review was to analyze the functions of mushrooms and the sensory terminology used for the sensory characterization of mushrooms and mushroom-enriched meat products. Efforts have been made to reduce animal fat, salt, synthetic additives, and meat, in which mushrooms stand out because they can replace these components. Various species have been explored, mostly with positive effects on physicochemical, nutritional, technological, and sensory characteristics. However, in the sensory aspect, the results are limited to the measurement of acceptability using a hedonic scale. Studies of the sensory properties of mushrooms relate terms beyond umami. For instance, terms such as fermented, yeasty, musty, earthy, crunchy, hard, sweet, mushroom, nutty, moist, and salty, among others, have been associated with various mushroom species. This terminology needs to be explored in mushroom-enriched meat products. However, little has been explored regarding consumer opinions for the generation of sensory terms to characterize mushrooms or mushroom-enriched meat products, which may be relevant for the purposes of reformulating healthier and more sustainable meat products. In this sense, future studies should explore diverse mushroom species, the amount and form of use, processing conditions, and functions. Therefore, better decisions can be made about which species to use, considering factors that allow for maximizing the benefits of mushrooms. This purpose can be achieved if the background of consumers who evaluate the products through their opinions is explored, which is a direct response to the industrial scaling of mushrooms as new ingredients in meat products.
