A set of collaborative studies was carried out on 6 food items in order to determine their contents phytosterols. The interest of these studies is to make it possible to calculate a certain number of figures of merit for methods known as of reference methods. Finally, the calculation of the function of uncertainty for these methods shows that uncertainty remains high, especially for the weak concentrations, and that it must have a substantial influence on the evaluation of phytostérols intake. Similarly, it can be concluded that the analysis of phytosterols in foods remains a delicate operation which would deserve more attention from standardization bodies, especially in the current context of supplementation of certain foods.
Key words: collaborative studies / content phytosterols / supplementation
