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 the free fatty acid content of crude sunflower oil?
Free Fatty Acid content of crude sunflower oil was found to be reduced from 1.1 to 0.24 (% Oleic acid) after neutralization. The residual FFA content of the refined oil was less than the maximum specified value of 0.25 % in the BIS standard for pressed refined sunflower oil.
Why is refined sunflower oil popular in India?
Refined sunflower oil has found wide acceptance because of its high polyunsaturated fatty acid content, bland flavour, good storage stability and low viscosity (Semwal et al. 1996 ). Refined sunflower oil has emerged as one of the most popular cooking oil in India.
