Why is crude sunflower oil difficult to refine?
Crude sunflower oil, which has reached a certain level of oxidation is difficult to refine. There are two main difficulties: and sometimes when the autooxidation has really gone too far fix colour formation, which is not removable by bleaching and/or heat bleaching.
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.
How to protect sunflower oil from oxidation?
The most sophisticated and environmental friendly solution is the icecondensing system, which is completely closed, it produces as much as waste water equal to the amount of direct steam used, and it eliminates all the smell problems too (14). The sunflower oil is sensitive to oxidation, that is why it is very important to protect it.
Can you buy crude sunflower oil from a foreign country?
New techniques like countercurrent bleaching and electrofiltration (ÖHMI) are under development (11). Purchasing crude sunflower oil (or seed) from certain countries involves the risk of PAH’s (polyaromatic hydrocarbons) contamination, originated from direct fuel gas drying of the seeds or from environmental pollution.
Why is sunflower oil turbid?
Crude sunflower oil contains waxes, which are long chain fatty acid ester with long chain alcohol (C44 – C60). These waxes crystallise at room temperature and cause “turbidity” in the refined oil. That is why it is necessary to remove them in order to produce “bright oil”.
What is tocopherol in sunflower oil?
Tocopherols are natural antioxidants, α tocopherol is known as Vitamin E. Tocopherol composition of sunflower oil has a great advantage for natural Vitamin E producers containing more than 90% of α tocopherol and only traces of β and γ isomers.
