Effect of refining on quality and composition 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. The phosphorous content, FFA content, peroxide value and wax content decreased during the refining process.
This behavior can be attributed to natural antioxidants in this oil as well observed to refined sunflower oil (unsaturation 88.40%), which the IP shifted from 5.5 to 7.5 h, respectively, in control and sunflower oil added polyphenol, subjected under a temperature of 110°C with airflow 20 L h −1 . Furthermore, the unsaturation amount of fatty

Abstract. 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
Effect of refining on quality and composition of sunflower oil
The quality and composition of crude and refined oil were analysed compared. Reduction in phosphorous content from 6.15 ppm to 0, FFA content from 1.1 to 0.24 % (oleic acid), peroxide value from 22.5 to 7.9 meq/kg, wax content from 1,420 to 200 ppm and colour absorbance value from 0.149 to 0.079 (in spectrophotometer at 460 nm) were observed
The campesterol contents of canola oils taken during rafination were determined between 6.01% (deodorized oil) and 7.90% (bleached oil) while stigmasterol contents of canola oil samples vary
Oryzanol as natural antioxidant for improving sunflower oil
Sunflower oil was incorporated with Oz concentrate to provide 0, 0.12, 0.25, 0.50, 0.84, 1.0, 1.60, 2.0, 2.5 and 3.20 % oryzanol in the oil, stored for 5 weeks at 37 °C and oxidative stability was evaluated. It was found that the oryzanol concentrate showed good antioxidant effect with increase in concentration of oryzanol.
The physico-chemical parameters of crude sunflower oil, refined oil obtained from the experimental unit and commer-cial refined oil sample is given in Table 1.Theoilsamples were found to be completely moisture free after refining and less than the maximum limit of 0.1 %. The specific gravity of crude and refined oil at 20 °C were found to be
- Can sunflower oil be refined?
- 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 chemical refining process of sunflower oil?
- Chemical refining process starts with crude oil and is treated for degumming and neutralization, which is followed by bleaching the oil and last it goes through winterizing and deodorizing stages . The detailed process of sunflower oil from its crude oil has been described in Fig. 1. Fig. 1.
- Does sunflower oil retain more tocopherols in chemical refining process?
- In chemical refining process, sunflower oil retained more tocopherols compared to the physical refining method. However chemical refining is considered less efficient due to saponification of neutral oil. 1. Introduction Vegetable oils are obtained through two primary methods: pressing and extraction.
- What is the difference between physical and chemical refining of sunflower oil?
- Tocopherol loss during physical refining was higher by 10% than in chemical refining due to the high temperatures used during the deodorization process, which removes free fatty acids in sunflower oil. In chemical refining process, sunflower oil retained more tocopherols compared to the physical refining method.
