Oils extracted from red and yellow strawberry guava seeds showed high levels of polyunsaturated fatty acids (PUFAs) and their chemical composition is presented in Table 3 and Figure 2. Fatty acids content and composition were every similar for both strawberry guava cultivars. The main fatty acid in both seeds was linoleic acid (61.01% ± 2.51%, 75.42% ± 3.50%, respectively). There was, however, a quantitative difference in the content of the 2nd major component, plamitic acid. For yellow strawberry guava the level of this acid (19.92% ± 0.26%) was more than double that of red strawberry guava (9.12% ± 2.12%).
