文摘

We have synthesized a new amphiphilic block oligomer by the enzymatic linking of a fatty acid (lauric acid) toa fructan oligomer (inulin) and tested the functionality of this carbohydrate derivative in foam stabilization. Thestructure of the modified oligosaccharide was found to be (Fruc)_n(Glc)₁CO-C₁₁H₂₃, which implies that on averageone lauric acid molecule was linked to one inulin molecule. The new component produces foams with exceptionalstability. Our results show that enzymatic acylation can produce an entirely new class of amphiphilic materials, withfunctionality comparable to that of synthetic block copolymers.
