Yogurts enriched with milk proteins: Texture properties, aroma release and sensory perception

Publication date: Available online 13 February 2020Source: Trends in Food Science & TechnologyAuthor(s): Hanna Lesme, Cecile Rannou, Marie-Helene Famelart, Saïd Bouhallab, Carole ProstAbstractBackgroundToday's consumers demand natural and healthy functional food products with clean labels and less added ingredients and exogenous hydrocolloids. The goal is to produce dairy foods only made by using milk ingredients, while maintaining good sensory properties. Thanks to their multifunctional properties, dairy proteins are used to enhanced the texture of dairy products. However, their addition into dairy products can also have a great influence on taste and aroma perception.Scope and approachThis review concentrates on recent information regarding the impact of dairy proteins in dairy products with a focus on yogurts. The aim of the review is to highlight recent findings relating the composition and the physico-chemical properties of yogurts to their sensory properties.Key findings and conclusionsThe addition of dairy proteins in yogurts induces changes in their microstructure, which can explain the modifications of their texture properties. Modifying the protein content also tends to decrease the release of most flavor compounds, which can impact the overall aroma balance and change aroma perception. Modifications of texture and aroma perceptions can also be due to cognitive interactions. Dairy protein aggregates are particularly promising as dairy texture enhancers, however alm...
