Corn oil is currently commonly sold edible oil, in the preparation process is divided into pressing and leaching method, because it contains rich vitamin content and a large number of unsaturated fatty acids, minerals and other nutrients, so the audience rate in the market is good. So is there any difference in the use of the refined oil obtained by the pressing method and the leaching method in the edible process of corn oil?
Pressing method: relying on physical pressure to separate the oil directly from the oil, without any chemical additives in the whole process, to ensure that the product is safe, hygienic, pollution-free, and the natural nutrition is not destroyed. Its output rate is about 65%, so it is generally suitable for small and medium-sized corn oil production plants
The smoke point of pressed corn oil is about 190, and when eating, because the stability of pressed corn oil is poor at high temperature, it is easy to produce toxic substances harmful to the human body, so it is not suitable for frying. Therefore, pressed corn oil is suitable for stir-frying, stewing, etc., and can also be used to make cold dishes and other foods with low temperature, which has the characteristics of light taste and no peculiar smell.
Leaching method: the use of organic solvent to extract and dissolve the oil in the oil, and then through the method of heating stripping to remove the solvent in the oil, the production capacity is large, the safety is high, and its output rate is 97%, so it is suitable for large-scale corn oil producers
The smoke point of refined corn oil is about 230, and when eaten, it can be used to fry and cook vegetables, and can also be used to fry food. The fatty acids of corn germ oil are structurally stable because they are arranged in a regular shape with glycerol, and they have considerable stability even when they are deeply fried, and have a longer shelf life than other oils, which can not only maintain the color and fragrance of vegetables and foods, but also do not lose their nutritional value.
When choosing between pressing and leaching, consumers can choose according to their own needs and preferences, such as if they want the edible oil to better retain the flavor of the raw materials during cooking, the leaching method may be a better choice;However, if you are more concerned about the purity and health of the edible oil, then the pressing method may be more suitable. At the same time, different oils may be suitable for different cooking methods, so please pay attention to the scope of application when using, so as not to affect the taste and quality of the food!
