Matters needing attention in blending oil
When we buy blended oil, we should also carefully look at the proportion of various fatty acids and trace accompanying substances. The nutritional value of blended oil mainly depends on whether the proportion of various fatty acids can meet or approach the needs of human body. Most regular manufacturers will mark the proportion of various fatty acids on the packaging of blended oil, so consumers need to read its trademark carefully before buying.
At the same time, we should also pay attention to its production process. Blended oil mainly consists of two processes: oil pressing and leaching. It is best to choose the blended oil by pressing method when buying, because pressing method will not produce harmful substances, while leaching method will produce some substances harmful to human health although it has high oil yield and low cost.
