High oleic sunflower seed oil has better oxidative stability and higher nutritional value, and is a high-quality edible oil with market potential and competitiveness. How is it different from regular sunflower oil? Compared with ordinary sunflower seeds, what are the properties of high oleic sunflower oil? This article will take you to explore.
1. Fatty acid composition
The igh oleic sunflower oil's fatty acid composition and ordinary sunflower oil was identical, with 8 fatty acids. However, there were significant differences in the content of these 8 fatty acids. The oleic acid content of high oleic sunflower oil is 81.23 percent , which is 56.29 percent higher than that of ordinary oleic sunflower oil. The linoleic acid content of high oleic sunflower oil is 11.06 percent , which is 52.36 percent lower than that of ordinary oleic sunflower oil. The fatty acids of the two sunflower oils are very different, and the following two reasons may cause the analysis:
1). The same variety of sunflower seeds has high oleic acid content at high altitudes.
2). Genetic engineering has become an important means of crop breeding. The traits of plants and the nutritional value of their products can be improved through transgenic technology. Now people have been able to change the composition of fatty acids in vegetable oils by genetic engineering, and have been successful in a variety of oil crops to meet people's needs for different fatty acids.
In addition, the content of saturated fatty acids such as palmitic acid and stearic acid in high oleic sunflower seed oil is 3.94 percent lower than that of ordinary sunflower oil. Therefore, from the perspective of fatty acid composition and content, the content of monounsaturated fatty acids beneficial to human health in high oleic sunflower oil was significantly increased. The content of saturated fatty acids that are not conducive to human health is reduced, which improves the nutritional quality of sunflower oil to a certain extent.
