THE COMPOSITION OF THE VOLATILE COMPONENTS AROMATOBRAZUYUSCHIH STRAWBERRIES GROWN IN BELARUS

Abstract

The method of solid-phase micro extraction (SPME) and gas chromatography with mass selective detector (GC-MS) were examined for the content of volatile components of 27 samples of strawberries of different varietal affiliation and degree of maturity, grown in Belarus. It was identified and evaluated relative content of more than 60 components of different nature, including esters, terpenes and other aroma-compounds. Esters belonged to two sub-esters - saturated and unsaturated esters. It is shown that the relative content of esters depends on the degree of maturity of the fruit of the strawberry: to overripe fruit prevails in saturated esters, for immature - a major contribution to the total content of esters of unsaturated esters introduced. The ratio of saturated esters, unsaturated esters to the content can be used in practice as an evaluation criterion of ripeness. The paper concluded that the component composition of strawberries, determined using the method of SPME, does not provide sufficient grounds for referring them to a specific varietal origin.
