At first glance, the transparency shows that the pure vegetable oil is transparent, the "saliva oil" is colored, and there are sediments and impurities. ? Second, drop one or two drops of oil on the palm of your hand, rub your hands together, smell it when you are hot, and it is likely to be "saliva oil" with peculiar smell and odor. ? Third taste, take a drop of oil with chopsticks, which tastes sour or bitter, indicating that it has become sour and corrupt, and may be "saliva oil". ? Listen, take one or two drops of oil from the bottom of the oil layer and smear them on flammable paper. The combustion is abnormal and a "crack" explosion sounds, indicating that the water content of the oil is seriously out of standard and the quality is problematic. ?
