| Abstract:
Yield, composition and behavior of fatty acids (FA) from lipids extracted from three avocado varieties during storage at 4, 7 and 18°C for 14, 28 and 33 days and an additional simulated marketing period of 6 days at room temperature (18 ± 2°C) were studied. Lipid fraction was extracted with a chloroform-methanol 2:1 v/v solvent. FA composition was determined by gas-liquid chromatography. Fuerte had the lowest lipid content, and had the longest storage period. About 78% of the lipids extracted are mono-unsaturated FA (palmitoleic and oleic) and between 8.63% and 13.32% are poly-unsaturated FA (linolenic and linoleic) and between 12.01% and 14.94% are saturated FA (palmitic and stearic). Although the three types of fruits showed variations in their FA content, they did not significantly change during postharvest storage. | |
