Then why is animal oil so delicious?
See the answer first:
In the cooking process, the flavor of animal fat stimulates people's taste buds and increases their appetite. Matching with other ingredients can make the flavor of food more obvious.
What is animal oil?
Animal oil, that is, animal fat, is animal fat. Animal oil for human consumption generally comes from pigs, cattle, fish, etc., and can be used to process food, so that food has the fresh flavor of meat.
Taking lard as an example, lard is one of the most consumed animal fats in China. Pig fat is extracted from the accumulated fat of specific internal organs of pigs and subcutaneous tissues such as abdomen and back. The fat accumulated in internal organs is generally hard, and the fat in subcutaneous tissues such as abdomen and back is soft. Edible pig fat is white in color, low in free fatty acid content, high in freezing point, solid in winter and semi-solid in summer.
Where does the aroma of animal oil come from?
Animal oil itself has a unique fragrance, and the smell of oil is one of the basic properties of matter. Smell is one of the most important sensory characteristics of oil, and it is also one of the important factors that constitute the flavor of oil.
Every animal has its own characteristic flavor. The characteristic aroma of different kinds of meat comes from animal fat, and the oil aroma component is a trace component, the content of which is generally below 1% of the total oil, but it constitutes its own characteristic aroma.
Animal fats and oils undergo oxidation reaction under high temperature heating, and hydrocarbons with very low aroma threshold are generated. The compounds of acids, ketones, acids and esters have meat flavor, and they play the most important role in the formation of characteristic meat flavor [1].
Therefore, the fragrance we smell when we stir fry in a hot pot comes from this.
Secondly, when animal oil is especially matched with radish, vermicelli and bean products, it can obtain delicious food that is difficult to achieve with other seasonings. Animal oil can also promote the absorption of fat-soluble vitamins A, D, E, K, etc. Using animal oil to stir-fry carrots was attracted from the aroma.
summary
The smell of animal oil will increase people's appetite and bring good taste enjoyment, but we can't eat three meals a day and use animal oil for every dish.
Animal oil and vegetable oil are both nutritious oils. Proper consumption of animal oil and vegetable oil can be more balanced and healthy.
