# Sensory Characteristics of Probiotic-Containing Foods: A Multidisciplinary Perspective on Enhancing Acceptability and Consumer Adherence

## TL;DR

This paper reviews how improving the taste and sensory appeal of probiotic foods can help people consume them more regularly, leading to better health outcomes.

## Contribution

The paper introduces a multidisciplinary approach to enhance probiotic food acceptability through sensory optimization and consumer behavior insights.

## Key findings

- Sensory attributes like flavor and texture strongly influence consumer adherence to probiotic foods.
- Technological innovations and sensory optimization can improve both product acceptability and consumer adherence.
- Cross-modal perception and cultural factors significantly affect how consumers experience and respond to probiotic foods.

## Abstract

Globally, the consumption of foods containing probiotics has increased significantly due to their well-recognized health benefits, including the modulation of gut microbiota and immune function. However, despite strong scientific support, daily massive adherence to probiotic food remains limited, mainly because of their suboptimal sensory appeal and the huge variability in consumer expectations. Sensory attributes—flavor, aroma, texture, and appearance—strongly influence liking, purchase, and the habitual consumption necessary for probiotics to exert the physiological effects for which they are consumed. The present narrative review explores the complex, multidimensional interplay between sensory features, consumer perception, and probiotic efficacy. By integrating evidence from nutritional science, microbiology, sensory science, and behavioral psychology, we outline how technological innovation and sensory optimization can improve both product acceptability and adherence. We also discuss how cross-modal perception, the cultural framework, and labeling influence hedonic responses. Finally, we highlight emerging directions, such as sensory-driven strain selection, omics-based flavor profiling, and personalized sensory nutrition, as tools to bridge the gap between scientific efficacy and consumer satisfaction. Improving the sensory design of probiotic foods is pivotal to translate microbiome science into meaningful, sustainable dietary behaviors that support the nutrition–gut–immunity axis.
