Raman Spectroscopic Barcode Use for Differentiation of Vegetable Oils and Determination of Their Major Fatty Acid Composition
Duraklı Velioğlu, Serap; Ercioğlu, Elif; Tümay Temiz, Havva; Velioğlu, Hasan Murat; Topçu, Ali; Boyacı, İsmail Hakkı (Wiley, 2016)In this study, differentiation of vegetable oils and determination of their major fatty acid (FA) composition were performed using Raman spectral barcoding approach. Samples from seven different sources (sunflower, corn, ... -
The use of Raman spectroscopy and chemometrics for the discrimination of lab-produced, commercial, and adulterated cold-pressed oils
Tümay Temiz, Havva; Duraklı Velioğlu, Serap; Gürbüz Güner, Kadir; Velioğlu, Hasan Murat (Elsevier, 2021)In this study, lab-produced cold-pressed oil samples of black cumin (CPBCO), almond (CPAO), and walnut (CPWO) were compared with their commercial substitutes. Additionally, adulteration of cold-pressed oils with corn and ... -
Use of Raman spectroscopy for determining erucic acid content in canola oil
Duraklı Velioğlu, Serap; Tümay Temiz, Havva; Ercioğlu, Elif; Velioğlu, Hasan Murat; Topçu, Ali; Boyacı, İsmail Hakkı (Elsevier Sci Ltd, 2017)This study presents a novel method to determine erucic acid in canola oil samples by using Raman spectroscopy and chemometric analysis. The oil mixtures were prepared at various concentrations of erucic acid ranging from ...
