Descrição
Resumo:The bottled butter consisted of anhydrous fat, consequently it is highly susceptible to lipid oxidation, and also it is crafts manly prepared without adequate processing control. In this context, the purpose of the present study was to evaluate the composition of fatty acids, predominantly on saturated fat and trans fatty acids, in 10 bottled butter produced and marketed in different regions of Bahia, Brazil. Also, the stability of bottled butter for period of seven months in samples stored at 5ºC was assessed by determining the peroxide index and acidity. The saturated fatty acids contents in analyzed samples ranged from 67.13 to 69.22% and the unsaturated ranged from 23.73 to 24.28%. The 18:1 trans fatty acids contents varied from 3.69 to 3.94%.All of analyzed butter samples showed high amount of peroxide at initial time (2.01-2.31 mEq / kg) and as light change after being stored for seven months (2.10-2.42 mEq / kg). The same pattern was observed in relation to acidity, being at first time 0.53-0.62% of oleic acid and 0.54-0.61% after seven months of storage. Although these bottled butter samples are handmade products, similarities on the identity characteristics were found among bottled butter samples on the market at different microregions of Bahia, Brazil.
