| Abstract:
The effect of storage temperature and duration on the relative fatty acid composition of triglycerides in "Marsh Seedless" grapefruit juice was investigated. No significant relationship was found between changes in fatty acid composition and storage temperatures. Significant changes did occur in relation to storage duration. The proportion of linolenic and palmitoleic acids increased during storage, while palmitic, stearic and oleic acid tended to decrease. Values under shelf-life conditions did not differ significantly from values at the end of cold storage, with the exception of palmitic acid which exhibited a decrease in fruit previously stored at 4 °C and 12 °C. Palmitic and palmitoleic acids as well as oleic and linoleic acids showed a negative linear correlation in all experimental conditions. | |
