以三种印尼鳄梨（Persea americana）品种Merah bundar、Ijo bundar和Ijo panjang为原料，与进口的富尔特（Fuerte）和谢帕德（Shepard）鳄梨为原料，对其油脂特性和生育酚含量进行了比较。除富尔特品种外，所有牛油果品种的油都以半固体形式存在。本地鳄梨油中的游离脂肪酸和过氧化物含量低于进口鳄梨油，这意味着本地鳄梨油具有更好的氧化稳定性。有趣的是，本地鳄梨油的生育酚（α、β、γ和δ）含量也远高于进口鳄梨油。同时，在1034和968 cm（-1）频率处发现鳄梨油的FTIR光谱存在差异。牛油果油的脂肪酸和甘油三酯组成也存在一些差异。由于这些差异，本地牛油果品种的油的理化特性、凝固特性和热特性与进口牛油果品种（富尔特和谢泼德）完全不同。
The oils obtained from three Indonesian avocado (Persea americana) cultivars namely Merah bundar, Ijo bundar and Ijo panjang, were compared to the oils obtained from imported Fuerte and Shepard avocado varieties in terms of lipid characteristics and tocopherol content. The oils of all avocado varieties existed in a semisolid form, except that of the Fuerte variety. Free fatty acids and peroxide levels in the oils obtained from locally grown avocado were lower than the levels in the oils obtained from imported avocados, implying that local avocado oils have a better oxidative stability. Interestingly, the tocopherol (alpha, beta, gamma and delta) content of local avocado oils was also much higher than that of imported avocado oils. Meanwhile, differences in the FTIR spectrum of avocado oils were found at frequencies of 1034 and 968 cm(-1). There were also some differences in the fatty acid and triacylglycerol composition of avocado oils. Due to these differences, the physicochemical characteristics and the solidification and thermal profiles of the oils obtained from local avocado cultivars were completely different from those of the imported avocado varieties (Fuerte and Shepard).
