Abstract :
[en] Probiotics are receiving today unprecedented growing interests in Europe, Asia, and in the rest of the world. Their applications are not only limited to food and health sectors, but cover also agriculture and aquaculture areas. The quality of probiotic products depends on many factors such as, the properties of each individual strain and its proportion in mixed products, the viable probiotic dose, and other selective ingredients like prebiotics and protectant agents incorporated into the formulation. Several strategies are employed for ensuring high product qualities, which can be controlled by different methods and techniques. To date, the physico-chemical approach for characterizing and controlling probiotic qualities and performances appears very attractive, but less exploited. It particularly consists in characterizing probiotic products in terms of thermal, surface and colloidal properties, which could be correlated to probiotic viability and functionalities. In this communication, we report the efficiency of such an approach when applied to a high concentrated multistrain-based formulation which has been shown a metabolic variability impacting on the inflammatory response, depending on the production site.
