Characterisation of five potato cultivars according to their nutritional and pro-health components

摘要

Introduction. Potatoes are very popular vegetables in Poland, not only in terms that they are easy to prepare, but also by the fact that they combine the wholesomeness of cereals and delicacy and characteristic chemical composition of vegetables, so it is important that they find their place in our diet. Nutritional value of potatoes is determined by the content of nutrients such as protein, starch, fat, minerals, and absence of toxins, as well as by a significant content of bioactive components from the group of polyphenols, which guarantee proper antioxidant activity of this vegetable. The study was performed in order to analyse 5 Polish potato cultivars, according to nutritional components, i.e.: proteins, fat, starch, carbohydrates, ash and biologically active compounds: such as polyphenols, flavonoids, as well as dietary fibre. At the same time antioxidant activity of the cultivars was determined by means of two independent methods.
