Does oil filtration assist with cellulose-based filtration aids affect chemical parameters?
The aim of this study is to examine the effect of oil filtration assisted by two cellulose-based filtration aids on the chemical parameters (wax, moisture, phospholipids, soaps, and fatty acids), oil transparency, carotenoids, and Fe and Cu content of sunflower oil obtained in an industrial horizontal pressure leaf filter.
How phospholipids and free fatty acids are removed from crude sunflower oil?
Phospholipids and free fatty acids are present as accompanying minor components of crude sunflower oil and they have to be removed during the oil refining process [ 64 ]. Most of the phospholipids and soap were removed during the degumming and neutralization phase.
Do cellulose-based filtration aids remove waxes from sunflower oil?
According to the results shown in Table 2, waxes content in sunflower oils after filtration (W_out) using cellulose-based filtration aids was very low. Waxes were practically completely removed from sunflower oil in all oil samples (98.97¨C99.42%, compared to oil samples before filtration).
What are the factors affecting the quality of crude sunflower oil?
Author to whom correspondence should be addressed. Waxes, phospholipids, free fatty acids, peroxides, aldehydes, soap, trace metals and moisture present in crude sunflower oil have a negative effect on the oil quality and are, therefore, removed during the refining process.
