Abstract (EN): Anthocyanins (ANC) are hydrophilic and water-soluble polyphenolic plant pigments. The current barriers to successful application of ANC in the food, cosmetic and pharmaceutical industries are predominantly related to performance, stability, formulation properties, and color. Enzymatic acylation of ANC could increase their stability without compromising bioactivity and chromatic features. Lipophilization of ANC-rich blackcurrant skin extract with Candida antarctica lipase B and octanoic acid was selective to cyanidin and delphinidin glucosides, but not the corresponding rutinosides. The reaction was chemo- and regioselective for acylation at the primary alcohol of the glucose moieties, greatly facilitating separation of the different glycoside derivatives.
