The fatty acid specificity of a lipase in the hydrolysis of natural oils and fats can be expressed by the following equation. The hydrolysis rate Hi of a fatty acid i in a fat is Hi= (fi/foi) ×H, where fi and foi are the molar fractions of fatty acid i in hydrolyzed fatty acids and that in unhydrolyzed fat, respectively. H is thus the hydrolysis rate of fat by lipase. Sardine oil was hydrolyzed by a microbial lipase and the results are presented graphically.
