The heat resistance of edible oil depends on its fatty acid composition. Oil with high saturated fatty acid content, good heat resistance, suitable for high-temperature cooking; However, oils with high content of polyunsaturated fatty acids have poor heat resistance and are easy to oxidize and deteriorate at high temperatures, producing harmful substances, so they are more suitable for low-temperature cooking.
The following cooking oils are suitable for low-temperature cooking:
Olive oil:Olive oil is rich in monounsaturated fatty acids and has good heat tolerance, but it should not be heated at high temperatures for a long time. Extra virgin olive oil has a better flavor and is suitable for low-temperature cooking methods such as cold dressing and dipping.
Flaxseed oil:Flaxseed oil is rich in linolenic acid, an unsaturated fatty acid that has important physiological functions, but has poor heat tolerance and is only suitable for cold or low-temperature cooking.
Perilla seed oil:Perilla seed oil is rich in linolenic acid and is also only suitable for cold dressing or low-temperature cooking.
Walnut Oil:Walnut oil is rich in polyunsaturated fatty acids, has poor heat resistance, and is suitable for low-temperature cooking.
Sesame Oil:Sesame oil has a strong aroma and is suitable for low-temperature cooking methods such as cold dressing and dipping.
Cooking at low temperature:
Cold salad:Mix the ingredients with cooking oil and seasonings.
Stew:Place the ingredients in a pot, add cooking oil, water or soup and simmer.
Steaming:Put the ingredients in the steamer and steam until they are done.
Notes:
The cooking time at low temperature should not be too long, so as not to affect the taste and nutritional value of the ingredients.
When using edible oil, attention should be paid to controlling the oil temperature to avoid the production of oil smoke.
Different cooking oils have different characteristics, and the right cooking oil should be selected according to the cooking method and the characteristics of the ingredients.
The above cooking oils are suitable for low-temperature cooking and can be selected according to personal preferences and needs. During the cooking process, care should be taken to control the oil temperature, avoid oil fumes, and maintain a healthy diet.
