Comparison of oil absorption from eggs and eggplant
Have you ever thought that our beloved breakfast regular's eggs may absorb more oil during cooking than the eggplant we think of as the "king of the oil sea"?
You may be a little surprised to hear this at first, after all, eggplant's ability to absorb oil is almost a household name.
But in reality, when eggs come across hot oil, they may surprise you with how they behave. This is not groundless, but has a scientific basis.
For example, when we usually scramble an egg, we put too much oil, and the egg seems to become "floating in the oil sea" in seconds.
Eggplant, on the other hand, also absorbs oil, but in some cooking methods such as baking or microwave ovens, it can greatly reduce its oil absorption.
This makes one wonder why eggs have such a strong oil appeal.
A scientific explanation of the oil-absorbing capacity of eggs
Eggs are mainly composed of two parts: egg white and egg yolk, and there is a lecithin substance in the egg yolk, which is not only an excellent emulsifier, which can make the oil and water mix evenly when making mayonnaise and other foods, but also promote the fusion of oil and eggs during the cooking process.
In addition, protein denaturation occurs when eggs are heated, a process that makes the egg loose and easier to adsorb and lock in oil.
When the surface of the egg is heated, it will form a porous structure, especially the small bubbles on the surface of the egg when frying, which increases the surface area in contact with the oil, which means that more oil is absorbed.
Taken together, these factors make the egg exhibit an extraordinary "oil-absorbing talent" in contact with oil.
Factors that affect the oil absorption effect of eggs
In addition to the structural characteristics of the eggs themselves, some details in cooking will also affect the oil absorption of the eggs. For example, the temperature when cooking is an important factor.
The higher the temperature, the more oil the egg absorbs. This is because high temperatures denature proteins more completely, more pores are formed, and more oil is naturally absorbed.
At the same time, the freshness of the eggs will also have an impact. Fresh eggs absorb less oil because they are more tightly structured.
The cooking method is also key, for example, omelette eggs usually absorb more oil than boiled eggs, because omelette eggs are in contact with oil all the time, while boiled eggs have no oil adsorption at all.
If you control these factors, you can better enjoy delicious and healthy egg dishes.
Health risks and culinary advice
Excessive fat intake is an important factor that leads to a variety of chronic diseases, such as cardiovascular disease, obesity and other health problems.
Although eggs are highly nutritious, if cooked improperly, excessive oil absorption can increase unnecessary fat intake and have a negative impact on health.
So, how to enjoy the delicious taste of eggs while reducing their oil absorption?
Choosing the right cooking method is crucial. For example, traditional frying can be replaced by boiling, steaming or microwave cooking, which not only reduces fat intake, but also keeps the nutrients of eggs intact.
Using healthy oils, such as olive oil or other vegetable oils that are high in unsaturated fatty acids, is also a good option.
These oils are stable at high temperatures and are cardiovascular.
There are also cooking tips to reduce grease use, such as applying a thin layer of oil to a pan before frying eggs and wiping it down with a kitchen paper towel.
This creates a very thin film of oil, which is enough to prevent the eggs from sticking to the pan, while also significantly reducing the amount of oil used.
Nutritional value and reasonable intake of eggs
Eggs are a nutritionally complete food that is rich in high-quality protein, vitamins such as B complex, vitamins D and E, as well as minerals such as phosphorus and zinc and important nutrients such as lecithin.
These nutrients play an irreplaceable role in maintaining good health and promoting brain development. Therefore, eggs play a very important role in our diet.
Reasonable intake is also key, and for most adults, 1-2 eggs per day is appropriate.
Certain populations, such as those with cardiovascular disease or high cholesterol, need to adjust their intake according to their doctor's recommendations.
Eating eggs in moderation allows us to get the necessary nutrients from them and avoid health problems caused by excessive intake.
