Exploring the Aroma Impact on the Taste of Plain Yogurt

In a groundbreaking study conducted by Meiji Co., Ltd., the sensory experience of plain yogurt has been meticulously analyzed, shedding light on how aroma influences taste. The primary focus of this research is on the scent perceived through the sense of smell, particularly in how yogurt is enjoyed in different scenarios: at the moment of opening the package, immediately after placing it in the mouth, and during chewing. Measurements taken during these specific moments reveal a significant connection between the aromatic compounds released from the yogurt and the sensations of freshness and milkiness that characterize its flavor profile.

The findings were presented at the 2025 Annual Meeting of the Japanese Society of Agricultural and Biological Engineering, held in Sapporo from March 4 to 8. This study utilized advanced techniques like Gas Chromatography-Olfactometry (GC-O) and Selected-ion flow-tube mass spectrometry (SIFT-MS) to identify and quantify volatile aromatic compounds in real-time. These methods allowed the researchers to visualize and understand the aromatic experience from the instant a yogurt package is opened until it is fully chewed.

Overview of Research Findings

Using GC-O analysis, distinctive aromatic components of yogurt were effectively identified. The SIFT-MS technique was utilized to ascertain the real-time quantification of the aroma released upon opening the yogurt. A sophisticated experimental apparatus was invented to simulate the temperature and mixing actions that occur in the mouth when consuming yogurt. This apparatus recreated two separate conditions: stationary (simulating the immediate mouth entry with no stirring or heating) and dynamic (simulating chewing with heating and stirring). The results demonstrated how specific aromatic compounds varied over time and how they influenced the perception of taste.

The research presented conclusive evidence about how freshness is perceived through the smell of acetaldehyde, recognizable by its apple-like aroma, immediately after opening. With continuous chewing, the aroma transitions into creamy fermented notes of acetoin and buttery scents of butyric acid, which intensify the milk flavor experience. This change mirrors the qualitative temporal dominance of sensations (TDS) analysis, confirming a correlation between the consumption process and sensory perception.

Implications of Research Findings

The study underscores the importance of the aroma in enhancing the yogurt experience. By making the aroma release upon package opening and the subsequent olfactory changes during consumption visible, Meiji aims to better convey the charm of its yogurt products to consumers. Influenced significantly by its ingredients—dairy and lactic acid bacteria—the aromatic profile guides customer appreciation and enjoyment of yogurt in daily life.

Purpose of the Research

The longstanding popularity of Meiji Bulgaria Yogurt, especially the flagship LB81 Plain variety, is attributed not only to its health benefits, such as intestinal flora balance and digestive wellness, but also its delightful taste. This research highlights how aroma contributes to taste perception, emphasizing how the sensory experience encompasses more than just flavor.

The study aims to elevate customer understanding of the aromatic complexity of yogurt and ensure that they can savor its rich fragrance daily. As the brand commemorates its 50th anniversary in December 2023, this innovative exploration of the sensory aspects of yogurt reflects Meiji’s commitment to quality and customer satisfaction.

Conclusion

The research conducted by Meiji Co., Ltd. marks a significant advancement in understanding how the interplay between aroma and taste in yogurt enhances the overall sensory experience. By focusing on the moments of aroma release, this study sets a foundation for further exploration into the delightfully complex world of yogurt consumption, promising to deepen consumer engagement and appreciation as they indulge in their favorite flavors. With an emphasis on freshness and milkiness, yogurt lovers can look forward to an enhanced experience thanks to scientific insights that bridge culinary art and sensory science.
