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.
Process flow diagramme for refining of sunflower oil. Degumming. The crude oil in the open conical tank was heated to 45 °C and degummed by adding 0.2 % phosphoric acid (50 % w/w strength) with slow agitation for 30 min. Then the oil was settled for 30 min and the water with dissolved gum was drained out.

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.
Effects of refining process on sunflower oil minor components: a review. A. A. Gotor, L. Rhazi. Published 1 March 2016. Chemistry, Environmental Science. Sunflower oil is well known because of its diversity of fatty acids profiles which allow different uses (food: dressing salads, margarines; nonfood: agrofuel, lubricants).

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. Recent developments in the field of processes
De-shelled pressing-leaching technology is the key point of sunflower oil production line which avoids the negative impact of over-refining, high temperature, and acid and alkali effects on oils, so that the nutrients in the oil can be well preserved. For example, the content of vitamin E in de-shelled squeezed sunflower oil is 75.5mg/100g.

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.
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. 5- 10% of the total C. 18:3.

Mid Oleic Sunflower Oil. on a collection of inbred lines. Otherwise, sunflower oil it is not particularly rich in carotenoids with only 1–1.5 ppm of carotenoids (Gunstone, 2011). The major carotenoids in sun-flower oil are xantophylls which reach up to 81% of the total (Rade et al., 2004). 1.1.4 Phenolic acids
It is very important for storing and using in cooking of dishes. Purified product has light and transparent color and does not spume, burn or scale while heating up. Unrefined oil has a strong odor, flavor and is pretty good for salads and cold dishes. This oil has a darker color and if does not used for a long time the lees appear.
