FULVIA-ANCUTA MANOLACHE, ANAMARIA HANGANU, DENISA EGLANTINA DUTA, NASTASIA BELC, DORU IOAN MARIN The Physico-chemical and Spectroscopic Composition Characterization of Oat Grains and Oat Oil Samples

Abstract:

In the present paper the chemical composition (protein, ash, crude fiber, total fat, total carbohydrates and moisture) of oat samples was determined. There were observed differences regarding the content of protein, crude fiber and total fat in the studied oat samples while ash, total carbohydrates and moisture content were approximately similar. The oat oils extracted by Soxtec system was analyzed using spectroscopic methods (1H-NMR and FT-IR) coupled with the chemometrical method Principal Component Analysis. Using 1H-NMR spectroscopy data and systems of chemometric equations, the composition of oat oils on four classes of fatty acids was established. The statistical processing of the data obtained from 1H-NMR and FT-IR spectroscopy illustrated a tendency to group of samples P1, P2, P3 and P4 with similar fatty acids composition and samples P5 and P6 with different one. This study can be used in authentication purposes. Keywords: oat, oat oil, 1H-NMR spectroscopy, FT-IR, PCA
