Abstract

Physico-chemical, functional and antioxidant capacities of 26 oat (Avena sativa L.) lines and cultivars were investigated. The results showed that the contents were considerably variable within samples, starch concentration (44,83-63,79%), carbohydrate (42,08-62,65%), protein (9,67-17,44%), fat (3,06-10,96%), β-glucan (1,37-6,05%) and ash (1,22-5,38%). The analysis of fatty acids composition indicated that, palmitic acid, oleic acid, linoleic acid, stearic acid and linolenic were the major fatty acids in oat lipids, and that the contents of total UFA in assessed material varied between72, 29-80,11%. Moreover, the phenolic content varied from 23,1 to 56,5 mg GAE/100g, carotenoids content range from 0,98 to 4,34 µg β-carotene equivalents/g and antioxidant activity, evaluated as DPPH radical scavenging activity, from 12,2 to 46,7%. The Protein profiles showed nearly identical nature of electrophoresis patterns, indicating no eventual change in protein quality. It could be concluded here that the flour of issue from these cultivars provide health benefits and high added value, if included as an ingredient for making new functional food products to meet the demands of health conscious generation.
