4.4. Cold refining. This process is an alternative to winterisation preceded by neutralization. However, use of the process is confined to oils with a relatively low FFA content as the oil losses are otherwise too high. Sunflower oil is therefore an ideal product for this application (Fig. 8).

Mesoporous silica aerogels for sunflower oil refining
Involving a succession of oil refining stages for edible oil production, a notable constraint lies in the necessity to employ diverse adsorbents at various steps within these processes. This study investigates the synthesis of mesoporous silica aerogels from rice husk ash, comparing their efficacy in physical sunflower oil refining with earth clay (Bentonite) and commercial silica (Trisyl
The final contents of total and individual trans-fatty acids of sunflower oil, produced during the deacidification step of physical refining were obtained using a computational simulation program that considered cis−trans isomerization reaction features for oleic, linoleic, and linolenic acids attached to the glycerol part of triacylglycerols. The impact of process variables, such as

Aflatoxin B1 contamination in sunflower oil collected ticular, neutralization process, including alkaline refining and washing and decolorizing processes, eliminated mycotoxins [10].
Alkaline refining of oils and fats is carried out using solutions of sodium hydroxide [4- 6] of different concentrations depending on the initial acid number of crude oil. In recent years, special attention has been paid to the use of new types of reagents in the technology of alkaline refining of sunflower oils.

The main drawback of alkaline refining is the loss of neutral oil—either been hydrolyzed by the caustic, or loss in the form of occlusion in soapstock. The soapstock can hold up to 50% of its weight of neutral oil (Bhosle and Subramaniam 2005). These undesirable situations take place especially upon extended processing time of high temperature.
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
- Does the refining process affect the quality of sunflower oil?
- Pal et al. (2015) examined the effect of the refining process on the quality of sunflower oil and showed that the AV content of crude oil decreased from 1.1 to 0.24 in laboratory refined oil and 0.13 in commercial refined oil.
- Does sunflower oil chemical refining affect tocopherol quality?
- 6) Effect of sunflower oil chemical refining on LCY and LCR respectively tocopherols except deodorization step. Deodorization step had a significant effect on all quality attributes of refined sunflower oil. In addition, although there was a linear relationship between oil stability index and degummed oil.
- Can sunflower oil be refined?
- An experimental oil refining unit has been developed and tested for 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 analysed compared.
- Does chemical refining affect oil stability index of sunflower oil?
- The effect of chemical refining on oil stability index of sunflower oil and other quality attributes free fatty acids, total tocopherols, colour and was investigated.
