Abstract
The objective of this study was to evaluate the nutritional compounds (fat, sugars, crude protein, soluble fiber, ash and starch) of four emmer wheat varieties grown under the conditions of organic farming system. The experiment was established on Scientific Research base Dolná Malanta, near Nitra in Slovakia during 2010 – 2011 and 2011 – 2012 growing seasons. Nutritional parameters, except crude protein content, were not influenced by the variety and weather conditions. Agnone variety had the highest content of fat, crude protein and starch but the lowest content of soluble dietary fiber. The lowest values of fat, crude protein had Molise sel Colli variety; Farvento variety had the lowest sugars and starch content. Emmer wheat as ancient wheat has a unique composition in secondary components, such as starch, which may play a role as functional food ingredients.
Highlights
The development of new speciality foods based on grain blends has permitted the use of the so – called “ancients wheats” as components that convey naturalness, unconventional and nutritional properties

Summary
The development of new speciality foods based on grain blends has permitted the use of the so – called “ancients wheats” as components that convey naturalness, unconventional and nutritional properties The attention towards these ancient species have been renewed by the increasing demand for traditional products, the request for species suitable to be grown in marginal areas and the need to preserve genetic diversity. Konvalina et al (2008) noted that the Middle East (Iran, Iraq, Jordan, Syria and Palestine) is its area of origin, where the wild predecessor (Triticum dicoccoides) is still cultivated At present, it is still cultivated in mountain regions and small areas in the Balkans, Turkey, Caucasia, Ethiopia, India, France, Italy and Spain (Marconi, Cubadda, 2005). The objective of present study was to evaluate influence of growing season and varieties on nutritional quality (content of fat, sugars, crude protein, soluble fiber, ash and starch) of selected emmer wheat varieties grown in organic farming in the south Slovakia
