植物食用油的選擇標準

How to select a quality cooking oil is a tricky question, let me list some criteria as follows
(1) Oils should be extracted using a mechanical way. We should avoid oils by chemical extraction, using solvent extracts.
(2) Because oils are used for cooking, they should be filtered in order to remove  impurities. Otherwise, those solid impurities will be burned and harmful to your health when cooked.
(3) However, oils should not be over-refined. Such oils strip off a lot of nutrition. You can judge them by color and smell. If they are pale yellow ( for peanut oils) and have no fragrant smell, the oils are over-refined.
