Title

The SPME technique as a useful tool to construct aromagrams of blue-veined cheeses

Abstract

The objective of the study was to assess the applicability of HS-SPME technique to construct aromagrams of the blue-veined cheeses. The study object constituted samples of the two blue-type cheeses produced in Poland (Lazur and Rokpol) and purchased in local supermarkets. To extract volatile components of the samples, a technique of headspace solid-phase micro-extraction (HS SPME) was applied. The compounds isolated were separated and identified using a gas chromatography and a mass spectrometry (GC/MS) technique. The contents of compounds detected were expressed in relation to the internal standard. Aromagrams of those cheeses were constructed. It was proved that a SPME technique coupled with a GC/MS technique are a useful tool for the analysis of the volatiles contained in the blue-veined cheeses, and can be helpful when constructing aromagrams of this type of cheeses.
