If you use a non-stick pan and silicone spatula to stir fry, it may blister if you put too much oil. The main reason is that the silicone shovel will vulcanize during heating, but these vulcanizing gases are harmless. After cooking, stop heating, and the vulcanization of silicone shovel will disappear. Will not affect human health, nor will it affect the taste of dishes.
In addition, the silicone shovel is not solid when it is made, because the silicone shovel has certain fluidity, so there will be hard plastic or metal materials as support in the middle. The bracket inside the silicone shovel will cause some air in the middle of the shovel. When the cooking oil is heated, the gas in it will expand when heated, and then some bubbles will be produced. If there is a little crack in the silicone shovel and bubbles overflow, then bubbles will appear in the oil pan.
Silicone spatula itself is non-toxic and odorless, but the manufacturers of silicone spatula are mixed, so many irregular goods flow into the market. When you buy it, you must be optimistic that it is produced by a regular manufacturer, otherwise the spatula with quality problems will also cause the oil pan to bubble and release harmful substances.
