Eight samples of different varieties of commercial ice-creams sold in Spain were analysed for their fatty acid composition, with relevance on their trans-fatty acid profile. Saturated fatty acids occurred in the largest proportions in all samples (mean = 68,1%), followed by monounsaturated (mean=2 1...

| Resumo: | Eight samples of different varieties of commercial ice-creams sold in Spain were analysed for their fatty acid composition, with relevance on their trans-fatty acid profile. Saturated fatty acids occurred in the largest proportions in all samples (mean = 68,1%), followed by monounsaturated (mean=2 1,1%) and polyunsaturated fatty acids (mean=5,2%). Trans-fatty acids were detected in all samples ranging from 0,5%-19%, mean value 5,7%. Statistical analysis (cluster analysis) based on their fatty acid profile (saturated, monounsaturated and polyunsaturated and trans-fatty acids) showed three groups of samples, depending on the main source of fat employed. |
