China has a nearly 40-year history of sunflower planting. In recent 20 years, sunflower seeds have ranked the second important oilseeds only to soybean. Sunflower oil contains necessary fatty acids needed by human body, beneficial for preventing heart disease, hypertensive disease and angiosclerosis, regarded as healthy oil.
Sunflower seed oil obtained by cold pressing has features as follows: light color, low phosphorus content, ect, while crude sunflower seed oil has wax content and slight turbidity at low temperature. Sunflower seed was cold pressed to obtain crude oil, then the crude sunflower seed oil was degummed, dried and dewaxed under certain conditions, and the dewaxing conditions of cold pressed sunflower seed oil were mainly studied. The dewaxing conditions were optimized by single factor experiment and orthogonal experiment as follows: crystallization temperature 10°C, crystallization time 16 h and stirring speed 12r/min. Under the optimal conditions, the contents of wax and unsaturated fatty acids in refined cold pressed sunflower seed oil were 27.8 mg/kg and 90.26%, respectively.
