✦ Synopsis
Hulled wheat grain is used mainly in the alternative or health food market. Most of the suggested beneÐcial e †ects of these cereals are due to speciÐc characteristics of their Ðbre. Pyrolysis/gas-chromatography/mass-spectrometry (PY/GC/MS) has proved to be a reproducible analytical tool for Ðbre analysis applicable to the analysis of cereal Ðbre. Pericarp Ðbre of 10 emmer and einkorn wheat landraces were analysed by PY/GC/MS and compared to a test durum wheat variety. The pyrolysis fragments derived from the polysaccharide fraction were signiÐcantly more abundant in emmers than in the other genotypes, whereas the highest percentage of lignin-derived pyrolysis fragments was detected in durum wheat. The genotype groups (winter and spring emmers, einkorn and durum wheat) were satisfactorily discriminated on the basis of the molecular composition of the Ðbre, whereas a discrimination within groups was not possible due to the limited number of samples available. The results suggest that the native emmer genetic material may represent a source of high-value dietary Ðbre. Breeding should aim at preserving such characters.
