1: Soybean oil or salad oil is the most commonly used. The purpose of brushing soybean oil or salad oil is to accelerate ripening, increase the color of food and reduce the loss of water in food. It is used in seafood and fish.
2. Seasoning oil, seasoning oil is generally squeezed out with onions, ginger and peppers. This oil can add flavor to food more than soybean oil. Mostly used for baking vegetables or bean products.
3. Animal oil, usually butter or sheep tail oil. This oil is mostly used in the ingredients of cattle and sheep. It is worth mentioning that some unscrupulous traders sell pork or other cheaper meat as beef and mutton, but it is generally not beef and mutton that is eaten with this oil.
4. Red oil, usually squeezed with pepper, is also squeezed with bean paste to increase the color and spicy taste of food. There is a food additive called "Pepper Essential Oil", which has been widely used in "Crazy Roast Wings" in China in recent years.
Pay attention to two points when making oil yourself.
1: filter the oil with a fine-hole sieve every morning or at the time of spreading, so that the contents in the oil can be considered, preferably after heating.
2. Self-squeezed oil will deteriorate in two or three days because it contains various substances and is not sealed. Need frequent replacement and bottom cleaning.
