Sažetak
Flaxseed is a valuable product, containing 34-35% fat, 23% protein, 22% nitrogen-free extract, 9% fiber, 3% ash and 8% water. It is widely used in chemical, food and pharmaceutical industry. Health promoting activity of flaxseed oil is mainly connected with the presence of essential fatty acids (EFA). On average, it consist of 50–58% α-linolenic acid (3), 15% linoleic (6) and 17% oleic acid (9) glycerides. However, the beneficial for health 3/6 ratio may vary depending on the cultivar type. To achieve both the high yields and the highest possible quality of raw material, new flax cultivars are introduced to agricultural production, as genetic factor can significantly affect flax ontogeny, including fat content and composition. The research aimed at selection of flax cultivars best for the production of the highest quality oil (the most desired set of EFA), as well as the cultivars whose seeds accumulate the lowest number of nutritional values. Namely, 28 flax cultivars were subjected to analysis, all registered in such countries as France, Netherlands, Austria, UK, Estonia, Canada, Romania, Czech Republic, Germany, Belgium and Poland. The analysis included comparison of such parameters as: crop yield, calorific value of flax seed, content of mineral and organic components, fat and protein yields, and also fatty acids chemical composition. The results showed that for different cultivars the crop yield may vary from 1.09 to 2.88Mg·ha-1 with corresponding calorific values from 121 to 325 MJ·ha-1. At the same time fat and protein yield averages respectively 420-1162kg·ha-1 and 302-764 kg·ha-1.
