Based on the most common vegetable oil blends, binary and ternary analytical mixtures were constructed in mass fractions from 0.50 to 0.97, and their fatty acid profile was determined and represented graphically. The fatty acids with discriminatory power were selected to construct equations to predict commercial oil blend proportions. Three different linear equations resulted from the analysis for i. palm oil-based blends: y = (0.3713 ± 0.0217)x + (11.401 ± 0.68) for C18:2 and (0.4357 ± 0.0254)x + (51.281 ± 2.90) for C16:0 ii. soybean oil-based blends y = (-0.0789 ± 0.0046)x + (30.686 ± 1.71) for C18:1 and (0.0686 ± 0.0040)x - (0.1395 ± 0.0081) for C18:3 and iii. sunflower oil-based blends y = (-0.0552 ± 0.0032)x + (12.167 ± 0.6105) for C16:0. Finally, the fatty acid profiles of n = 10 commercial samples (i.e., vegetable oil blends) were determined, and the model was applied to them with satisfactory results.

Yağ Asidi Profillerine Dayalı Yenilebilir Bitkisel Yağ Karışımlarının Ayırt Edilmesi, Nicelenmesi ve Tanımlanması

Öz

En yaygın bitkisel yağ karışımlarına dayalı olarak, ikili ve üçlü analitik karışımlar 0.50 ila 0.97 arasında kütle fraksiyonlarında oluşturulmuş ve bunların yağ asidi profilleri belirlenmiş ve grafiksel olarak gösterilmiştir. Ticari yağ karışım oranlarının tahmini için denklemler oluşturmak amacıyla ayırt edici güce sahip yağ asitleri seçilmiştir. Yapılan analizden üç farklı lineer denklem elde edilmiştir: (i) palm yağı bazlı karışımlar, C18:2 için y = (0.3713 ± 0.0217)x + (11.401 ± 0.68) ve C16:0 için (0.4357 ± 0.0254)x + (51.281 ± 2.90), (ii) soya fasulyesi yağı bazlı karışımlar, C18:1 için y = (-0.0789 ± 0.0046)x + (30.686 ± 1.71) ve C18:3 için (0.0686 ± 0.0040)x - (0.1395 ± 0.0081) ve (iii) ayçiçeği yağı bazlı karışımlar, C16:0 için y = (-0.0552 ± 0.0032)x + (12.167 ± 0.6105). Son olarak, ticari numunenin (n = 10, bitkisel yağ karışımları) yağ asidi profilleri belirlenmiş ve model, tatmin edici sonuçlarla bunlara uygulanmıştır.
