Morphological, Structural, and Functional Evaluation of Rice Starch Acylated in a System Catalyzed by the B‐Lipase of Candida antarctica
Abstract Starch modification by acylation induces significant changes in the mechanical and thermal properties of this polymer, widening the scope of its applicability to many different industries. In this work, the B‐lipase of Candida antarctica is used as a catalyzer for the acylation of F60 varie...
