Abstract:
1. A method of isolating an omega-7 fatty acid ester from algal biomass, comprising the steps of: (a) Extracting oil from algal biomass comprising C16:1 fatty acids; (b) Transesterifying the extracted oil to generate a first algal extract mixture; (c) Decanting the first algal extract mixture to separate a second algal extract fraction and a fraction comprising glycerine and water; (d) A first distilling of the second algal extract fraction to separate a third algal extract fraction and a fraction comprising carotenoids, chlorophylls, and unesterified material; (e) A second distilling of the third algal extract fraction to separate a fraction rich in omega-7 esters and a fraction rich in eicosapentaenoic acid (EPA) esters; and (f) Isolating the fraction rich in omega-7 esters from the fraction rich in EPA esters.
