An experimental oil refining unit has been developed and tested for refining of sunflower oil. Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared.
How is crude pressed sunflower oil refined?
Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared. The phosphorous content, FFA content, peroxide value and wax content decreased during the refining process.
Is palm olein good for frying?
Matthaus (2007) reported that palm olein was comparable with high oleic vegetable oils and hydrogenated sunflower and cottonseed oils in terms of oxidative stability during frying. Palm oil is resistant to oxidation, polymerization and foaming. Palm oil does not produce any gummy or sticky residues in the fryer.
What are the advantages of Physical refining of sunflower oil?
Physical refining has several advantages compared to the classical chemical one. This process is more economical (improved yield, lower investment cost, less chemicals used) environmental friendly process (no soapstock to be treated, splitted) but more sensitive to the crude oil quality. Physical refining of sunflower oil is discussed in details.
