How to choose good edible oil?

1. Look transparency, pure vegetable oil was transparent, if mixed with alkali grease, wax and other things, transparency will decline; see color, peanut oil is light yellow or orange; yellow soybean oil, rapeseed oil in a little green or yellow golden yellow; salad oil mostly light colored better.

2. Each oil has its own unique smell. You can drop one or two drops of oil on the palm, rub hands together, carefully smell the odor fever. Smelly probably is "waste oil."

3. Use chopsticks to take a drop of oil, carefully taste its flavor. Oil with a sour taste is substandard products, coke bitter oil rancidity has occurred, the oil with peculiar smell may be "waste oil."

4. Take one or two drops at the bottom of the oil, coated on the flammable paper, lit and listen to its sound. No sound is normal qualified products; combustion is not normal with a "creak" sound, excessive moisture, is substandard products; explosions burning oil showed the water content seriously overweight, and may is adulterated product, absolutely can not be bought.
