Hello, hello everyone, here is a smart medical code that is a little smarter today than yesterday. I'm smart!
After talking about a few periods of oil, a friend asked me, "Great clever, what do you mean by the first, second, and special grades on the oil?" Is the higher the better?
Indeed it is.

According to the provisions of the national standard, as long as the quality level is specified in the product standard, it must be marked on the packaging.
Most edible vegetable oils have their own quality grades, such as peanut oil from high to low divided into one, two, three grades; soybean oil, corn oil, rapeseed oil, rice bran oil, etc. from high to low divided into one, two, three, four grades.
These grades are determined according to the color, taste, the amount of insoluble impurities, oxidation, solvent residue rate and other indicators.
Put simply: higher grades mean better color, taste, less impurities, oxidation and solvent residues. That is to say: the quality grade of edible oil is of course good at the first level, the first level is better than the second level, and the special grade in olive oil is the best!
This is one level
This is three levels
Therefore, it is indeed recommended to give priority to the edible oil with a quality grade of one, of course, it will be more expensive.
However, low-grade edible oil does not mean that it cannot be eaten, as long as it is a qualified product, it can be bought home and weighed according to the comprehensive cost performance.
