The high grade of edible oil does not mean that the high nutritional value of the oil ,using the right oil is the key

Edible oil is an integral part of people’s diet ,there are variety of edible oil on market .When people buy oil, they will find that the oil has grade one, grade two and so on ,and olive oil with special  oil ..Is the higher grade the higher nutritional value? Public nutritionists suggest that the grade of edible oil actually represents the quality grade. The higher the grade, the higher the degree of refining ,But it doesn’t mean that the higher the grade, the higher the nutritional value of the oil . General edible vegetable oil in our country market (except olive oil and special oil) will be divided into level 1, level 2, level 3 and level 4 four grades, such as soybean oil, rapeseed oil, cottonseed oil, rice bran oil, corn oil, sunflower oil, leaching peanut oil, tea seed oil can be divided into one to level 4, and squeeze peanut oil, squeezing tea seed oil, sesame oil, etc., only have level 1 and level 2 ..The higher the grade, the higher the degree of refining . That is to say, the more fully refined oil is, the higher the quality of oil is. However, many beneficial components, such as carotene and vitamin E, will be removed during refining .So it is not the higher the grade, the higher the nutritional value of the oil.Some two, three, four levels of the nutrition of cooking oil is not necessarily lost to a level or extra.

When buying edible oil, need not care too much about grade .No matter what grade of edible oil, as long as it meets the national standards, it is safe to eat . When buying, you can choose according to your own needs and the needs of your family.For example, there are children, the elderly or pregnant women in the home, hope that nutrition can be diverse, can choose a lower grade, nutritional ingredients to retain more cooking oil .If you like the oil clean and flawless, looking very clear, you can choose the higher grade .You can also swap your cooking oil according you like  .For example, when cooking a high-temperature dish, use high-grade cooking oil with less impurities and less soot.When cooking dishes such as steaming, boiling, stewing and colouring, you can choose low grade oils .Low grade oil is more suitable for low temperature cooking because it contains more impurities.and a lot of soot will be produced at high temperature .
