Relation between fatty acids’ chemical profile and chemotaxonomy of Czech barley (Hordeum vulgare) varieties, their geographical origin and malting process

Popis výsledku v původním jazyce

The dependence of FA profiles in barley and malt on variety and geographical origin was determined using an optimized method. FA profiles from 6 Czech varieties, each from 5 localities, during two crop years were studied. Extraction of lipids and FA with hexane by fluidized bed extraction and hydrolysis of lipids prior to derivatization of FA was used. The statistical processing of FA profiles led to a differentiation of samples; the importance of distinguishing parameters decreases in the order of crop year ˃ geographical origin ˃ variety. Nevertheless, the differentiation of tested varieties using FA profiles coresponds to a varietal pedigree. A statistical difference in terms of the total lipid content was found between two varieties (Malz and Sunshine) and two tested localities. The profile of FA in barley grains is influenced by the land type and climate conditions. Due to a high level of barley varieties crossbreeding, the chemical profiling of FA is not a reliable tool for a varietal determination, however, it reflects the variety origin.
