Effect of refining on quality and composition of sunflower oil
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.
Crude canola oil is refined in order to remove undesirable minor compounds that make this oil unusable in food products. However, refining can also cause the removal of desirable health-promoting minor components from the oil.

Influence of refining of vegetable oils on minor components
Refining of crude vegetable oils involving degumming, bleaching and deodorization has a high influence on the content of functional minor components. In this study, the difference of chemical versus physical refining will be studied. Especially the reduction of the tocopherol content in refined oil is mainly due to oxidation of the tocopherol.
After the refining process, oil contains only about 1% of minor components but those substances play a significant role in shaping the quality of the oil (Xenakis et al., 2010). A refining process which removes most of minor components is often necessary to maintain a high-quality product ( Kachel-Jakubowska et al.,...

The effect of consecutive steps of refining on squalene
The aim of this study is to evaluate the effect of refining steps on the squalene content of some vegetable oils. A comparison has been made between the crude oils and consecutive steps of refining process (neutralization, bleaching, deodorization, winterization) in the amounts of squalene of the oil samples.

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.
Sunflower Oil for Skin: Benefits, Limits, and How to Use It
Sunflower oil is a non-comedogenic carrier oil which is highly absorbent, and won’t clog pores. It’s non-irritating for most people, and can be used on all types of skin, including dry, normal
Processes Involved in Sunflower Seed Oil Production
Sunflower seed oil production does the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extraction of crude oil from these seeds and then further refining the oil obtained before packaging.
