Abstract :
[en] Carbohydrate-based surfactants (CBS) are amphiphilic molecules with particular interests. These surface-active compounds can be produced from the most abundant renewable materials allowing large product concept possibilities. They may occur in a wide range thanks to numerous functional groups. These make possible the design of a quasi-unlimited compounds by (bio)-synthesis of new structures, or by modifying existing natural molecules. This structural diversity can generate a wide range of properties which could be developed in food and non-food applications. Our challenge is to find out the most suitable molecular structures for post)development of CBS according to the specific required properties in various industrial applications. This consists of assessing the interfacial properties of various CBS prepared by chemical, enzymatic, or chemo-enzymatic synthesis routes from the derivatives of bio-renewable materials.The effect of the polar head group, the hydrophobic chains (length, number), and the linker will be presented and discussed.
