Fatty acid composition also varies with harvest time. For instance, reported an increase in oleic acid and a decrease in palmitic, palmitoleic, stearic, linolenic and arachidic acids between November and January. In agreement with these data, also found an increase inoleic acid and a decline in palmitic, palmitoleic, but also linoleic acid content of avocado cvs. Ettinger, Fuerte and Hass sampled over the commercial harvest season. on the other hand, reported no changes in the fatty acid composition of Californian avocado cv. Hass sampled between January and September. So, total amounts of mono and polyunsaturated fatty acids in the fruit increase with later harvest in the year, as does lipid content.
