PHYSICAL REFINING OF SUNFLOWER OIL
Sunflower oil has a high nutritional value, having 62-70% linoleic acid content (essential fatty acid) but on the other hand this high polyunsaturated fatty acid content makes this oil sensitive to oxidation. Crude sunflower oil, which has reached a certain level of oxidation is difficult to refine. There are two main difficulties: 1.
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.
Sunflower Oil Refinery Plant Process, Oil Expeller
The steps involved in Sunflower Oil Refining Process: Degumming. Neutralization. Water Washing. Vacuum Drying. Bleaching. De-waxing. Deodorisation. The chemical refining stages of Sunflower oil are also similar to other soft oils except dewaxing which is additional as sunflower oil contains wax which will be removed by dewaxing process.
Summary: 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
Attempts of Physical Refining of Sterol-Rich Sunflower Press
At the industrial level, sunflower oil production consists of extraction by press (around 70–80% of the total oil is extracted) followed by solvent extraction (hexane) of the remaining oil. Both the press oil (PO) and solvent oil (SO) are blended to produce what is known as crude oil, which must then be refined for edible purposes .

Effect of refining on quality and composition of sunflower oil
The physico-chemical parameters of crude sunflower oil, refined oil obtained from the experimental unit and commer-cial refined oil sample is given in Table 1.Theoilsamples were found to be completely moisture free after refining and less than the maximum limit of 0.1 %. The specific gravity of crude and refined oil at 20 °C were found to be same
So liquid oil producers should deliver fully refined oil with less than 1-1.5% total trans for sunflower and rape respectively. Another, more strict demand is more specific for the fatty acid composition of the oil, so the degree of izomerization (DI) should be max. 510% of the total C18:3 and max. 0.7-1% of the total C18:2.
Sunflower oil, Chemical refining, Physical refining
Physical refining is a relatively newer method of oil refinement and consists of three main processes: hydration, bleaching, and deodorization. The key difference between. on Phospholipid and Total Tocopherol Content in Sunflower Oil. chemical and physical refining lies in the removal of free fatty acids.
World production of sunflower seed in 2018–2019 was 51.46 million metric tons which is the third in worldwide oilseed production. Sunflower oil is fourth in importance among vegetable oils
