What is the winterization process of sunflower oil?
Industrial Winterization Process The winterization of sunflower oil takes place after the neutralization phase. The neutral oil was cooled and treated with a dilute sodium hydroxide solution. Then, the oil was crystallized by slow mixing in tanks at 8 °C.
Does the soap content in sunflower oil change during refining?
The soap content in sunflower oil changes in certain refining phases, including winterization. In addition to waxes and phospholipids, the soap content also differed in the oils before and after filtration. In all examined oils sampled before filtration (S_in), the presence of soap was detected.
How to control the quality of sunflower oil?
Control of the required level of quality of sunflower oil is all stages of the process, output control of products. research. The regulatory r equirements for this product are outlined in TR TS 024/2011, GOST 1129- 2013 in terms of organoleptic, physicochemical and safety indicators. One of the main requirements is called a cold test.
What is the wax content of sunflower oil after filtration?
The highest wax content (W_in) was determined in the oil sample F_08 and amounted to 549 ± 11 mg kg 1, while the lowest wax content was sample F_16 (281 ± 8 mg kg 1 ). According to the results shown in Table 2, waxes content in sunflower oils after filtration (W_out) using cellulose-based filtration aids was very low.
