Disclosed is a method of producing an estolide having high structural stability, including: a) preparing a fatty acid mixture from biomass-derived oil; b) separating the fatty acid mixture into a C16 fatty acid and a C18 fatty acid; c) converting the C18 fatty acid into a C18 or C17 linear internal olefin; and d) subjecting the C18 or C17 linear internal olefin and the C16 fatty acid to an estolide reaction, thus obtaining an estolide.
