[New food product containing polyunsaturated fatty acids Omega-3 EPA, DHA: sensory quality and possibility of diet supplementation].

Polyunsaturated fatty acids omega-3, especially long chain forms--EPA, DHA, exert desirable influence on human health by decreasing risk of many life-style diseases. However intake of these is usually too low, that brings many unfavourable health effects. Increased consumption of omega-3 fatty acids (up than 200 mg/day) is now commonly recommended. In Poland EPA, DHA intake is only about 100 mg/day, one of the lowest in Europe. A way to arise EPA, DHA amount in the diet, without radical changes of eating habits, seems to be consumption of foods containing its addition. The aim of the study was to explore the possibility of omega-3 polyunsaturates EPA, DHA in microencapsulated form use for formulation of high sensory quality pastilline form foods (orange and mint flavour versions), and to evaluate influence of 4 mts. storage time (room temp., no access to light and air) on sensory quality. Sensory evaluation was performed using methods of sensory analysis. Following sensory features were evaluated: palatability (structurized graphic scale method), intensity of fishy flavour (non structurized graphic scale method), and sensory quality (succesion method). Results were statistically interpreted. It was shown that palatability of elaborated foods wasn't significantly affected by EPA, DHA concentration up to 0.8-1%, depending on presence of flavours masking fishy taste of omega-3 polyunsaturates, during whole storage time. Daily intake of 5-10 units of elaborated products provides 65-150 mg EPA, DHA, i.e. 35-70% of its minimal proposed intake (total energy 22-44 kcal, i.e. 91-182 kJ). That may increase EPA, DHA amount in average Polish diet by 70-140%, elevating them towards recommended one.
