  • Can sunflower oil be refined?
  • Conclusion 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.
  • What is the residual FFA content of refined sunflower oil?
  • 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. During the chemical refining process, most of the FFA content was eliminated during the neutralization stage as soap because of the alkali treatment which improved the quality of oil.
  • How was crude sunflower oil refined?
  • Testing of the refining unit Mechanically pressed crude sunflower oil was obtained from a local oil mill. The crude oil was kept in tin container away from the light, high temperature and oxygen to avoid auto oxidation. The oil was refined in the developed experimental unit as per the process flow diagramme shown in Fig. 1.
  • 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.
