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.
How is crude pressed sunflower oil refined?
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.
What is a sunflower oil refining unit?
An experimental oil refining unit has been developed for minimal refining of sunflower oil. The unit consists of (i) one open mild steel tank with conical bottom for degumming/neutralization, (ii) one closed oval tank for vacuum drying/bleaching and (iii) one filter for filtration of oil.
What is the average reduction in sunflower seed oil during refining process?
Total average reduction for sunflower seed oil samples during refining process was 32.9%. The level was about 13.8 mg/100 g in crude sunflower oil and about 9.2 mg/100 g in refined sunflower oil. Losses (%) of minor components during each step pf the refining process.
