摘要：Background. Liver pâtés are popular all over the world, but they usually contain high amounts of animal fats. It may be beneficial to improve their dietetic value by decreasing the saturated fatty acid content, while maintaining their sensory quality. One way to do this is to add ingredients which are rich in polyunsaturated fatty acids, such as hemp seed or linseed. Hemp seeds are valuable because of their fat and protein content and linseed is known for its high α-linolenic fatty acid (ALA) content. Both are good sources of fiber. Material and methods. Three pork liver pâtés were produced: one with hemp seed, one with both hemp seed and linseed and one with neither. The products were tested by 50 consumers, a proximate analysis was conducted and the fatty acid profile, texture and color of the pâtés were analyzed. Results. The addition of hemp and linseed increased the fat content. The fatty acid profile improved significantly. There were more polyunsaturated fatty acids and the n-6 to n-3 ratio was reduced in both products containing oil seeds compared to the control sample, which is important from the health point of view. The color parameters were not changed. The hardness, chewiness and adhesiveness increased in products containing oil seeds. Those products received higher scores in sensory analysis. Conclusions. The quality of the pâtés with added oil seed is comparable to or better than the traditional ones. The products with both hemp and linseed can be treated as a good source of n-3 fatty acids. The amount of ALA is high enough to label the product as a source of n-3 fatty acids.
