Today, people often use metal or plastic barrels to hold edible oil, which is actually very unscientific because metal molecules and plasticizers in plastics can accelerate the rancidity and deterioration of edible oil.
Therefore, long-term storage of edible oil in plastic bottles can pose certain risks., The composition of plastic is very complex, it is a polymer compound with plasticity. A certain amount of plasticizer and stabilizer will also be added to fix the shape of the bottle; In order to make the bottle colorful, some industrial pigments are also added to enrich the color of the bottle. And these plasticizers, industrial pigments, and other chemical substances may be harmful to the human body, and some components can also cause cancer.
Glass container manufacturers suggest choosing a reasonable container for storing edible oil, choosing a dark colored glass container that is not transparent to light. Seal the bottle mouth, and place the glass container in a cool, dark, dry, and low temperature area to minimize contact with air and sunlight. The storage temperature of edible oil should be 10-15 ℃, and generally should not exceed 25 ℃; It should not contain moisture. Adding 40:1 hot oil to the oil can be used to absorb moisture. Glass container manufacturers suggest that it is best to buy and use edible oil in summer, and put it in a dry place in winter.
