Abstract Lipase‐catalyzed selective partial hydrolysis of evening primrose ( Oenothera biennis L.) seed oil and borage ( Borago officinalis L.) seed oil led to an increase in the level of γ‐linolenic acid (GLA; 18∶3n−6) in the unhydrolyzed acylglycerols. Thus, in evening primrose oil, the GLA level...
