What is the floating film on the top of the porridge when boiling it?

Porridge is also a kind of food that we often eat in daily life, usually when we cook porridge, there is a layer of floating film on it, this layer of floating film is also very nutritious, it can also be called rice oil, so this layer of floating film, it is like a layer of milk skin on the milk is the same reason, so we are also very common when cooking porridge This kind of rice oil, rice oil is also after a long time of rice boiling, the formation of a substance floating on the rice, it is also the main ingredient of starch decomposition into glucose.

1. Porridge also contains protein.

When we cook porridge, the porridge also contains protein, fat and other substances, the freezing point is low, and they are also lighter than starch, so when we cook porridge, it will also form a layer of foam and float on it.

Second, we will put the meal on the table every time to cold.

In the process of colding, a layer of floating film will be formed on each bowl of rice, and this layer of floating film is also very nutritious and can be used directly.

3. This layer of rice oil is also very good for the human body.

Usually when we eat this rice oil, it is very good for the elderly, mothers, or children, and the infirm, and it also has the effect of tonifying and filling semen.

So in life, when we make porridge, there will be such a situation, so there is no need to worry, because this is not a harmful substance, which is also very good for the human body, because this also shows that our own rice is also very nutritious, because we sometimes, the rice bought in the supermarket, it may not have this kind of rice oil.

Therefore, in daily life, we eat porridge more, and there are many ways to make porridge, and we can also make millet porridge.

Millet porridge is also relatively nutritious, and it is also very nourishing to the stomach. Therefore, in life, we can also put some millet in when cooking porridge, which is very good for the elderly and children in the family.

In fact, the membrane on the porridge is rice oil, which is very nutritious and looks like a viscous and delicate substance.

This is a layer of rice oil, which always happens when boiling porridge, and it is not caused by any special reason.

It is rice oil, and the temperature is relatively high during the boiling process, so it will appear above, and the nutritional value is still relatively high, and a lot of protein can be supplemented.

It is a kind of rice oil produced when boiling porridge, this layer of rice oil is harmless, on the contrary, it has high nutritional value, and it is also delicious.

The membrane on top of the porridge is rice oil.

Rice oil is a substance that floats on the surface formed by rice after a long period of boiling, and the main component of rice, starch, is broken down into glucose, and the intermediate product is dextrin, and there is a small amount of simple sugar. The longer the rice is boiled, the more fully gelatinized, the more rice oil, and the more fully digested and absorbed by the human body.

Millet porridge is not only delicious, but also nutritious and comprehensive. If you want to get high-quality porridge oil, the pot used to cook the porridge must be brushed clean and there must be no oil stains. When cooking, simmer slowly over low heat, and do not add any ingredients.

In addition, millet can also be cooked with beans to cook porridge, millet, purple rice, corn, red beans, mung beans, peanut beans, and red dates together until sticky.

Meat with clear lines, such as pork on the back, has clear lines and fewer capillaries, which makes it easier to wash away residual blood, so there is less foam when cooking soup. However, meat with complex textures and rich capillaries, such as meat on legs and shoulders, wants to remove the residual blood in the meat There are many odorous substances in the meat, such as fatty amines, aldehydes and ketones, heterocyclic compounds, etc., many of these substances are water-soluble, but more are fat-soluble, that is, they are easier to dissolve in fat.

When blanching stewed meat, bone broth, and pork, there is always foam on top of the water, and the main ingredients are fat, protein, animal blood, impurities, etc. When consumed, it affects the taste and aesthetics. So it's best to remove it, and the white foam that appears later is protein and oil.

The inside of the meat is relatively not that high. As for other harmful substances that may be carried, they are definitely concentrated in the liver, followed by other internal organs such as the kidneys. In short, the foam comes from the meat, and there must be fewer ingredients that come out of the meat than those that remain in the meat.

In addition to fat and lean meat, there are actually many tissues in the middle of the meat, such as fascia in the middle of the meat, connective tissue and other things, and even some blood. These things are actually fragrant on their own, but they can easily be broken down when heated, and they become foam when they float on the surface of the soup. Therefore, the blood in the foam mainly comes from the capillary residue in the meat, and it is also the component that accounts for the largest proportion of the foam.

When you cook different parts of meat, the amount of foam produced will be different, because the abundance of capillaries in different parts of the meat is different.

The foam of the broth is mainly composed of proteins and fats, which include both hemoglobin in the tainted blood and hydrolyzed collagen and elastin. Studies have shown that there are not only saturated fatty acids, monounsaturated fatty acids, but also polyunsaturated fatty acids in the broth foam, do not put salt when cooking meat, and wait for the meat pieces to be cooked before putting salt, too early salt, will form sodium nitrite, sodium nitrite is one of the main causes of cardiovascular disease.

When boiling porridge, the floating film on top is rice oil, which is a thick liquid, which is very nutritious and better than porridge.

This layer of film is called rice oil. This layer of rice oil is very good, with high nutritional value, which can replenish qi and blood.

This floating film is the nutrients of porridge, is the essence of porridge, the nutritional value of these things is very high, ordinary people rarely know, will waste don't.

In order to prevent the rice soup from overflowing and the dirty pot from extinguishing the fire, the scum is mixed with rice bran and other dirty things, and the porridge can be cleaner after being skimmed out.

Both rice and flour contain some proteins, and some of them will dissolve in water during the cooking process to act as a surfactant. In addition, some of the starch in the rice and noodles will also dissolve in the water, increasing the viscosity of the water.

A high viscosity soup contributes to the stability of the foam, which means that the higher the viscosity of the soup, the more foam it may have. This noodle soup and rice soup are thick and fragrant, and these foams are not harmful to health, so you can eat them with confidence.

Because the old cang rice is stored for a longer time than the new rice, the smell and taste become diluted and calm. But it is also because of the "light" that it can nourish the stomach, so Chen rice is very helpful for people with weak spleen and stomach after illness. The "Compendium of Materia Medica" mentions:

Chen Cang rice boiled juice is not muddy, the smell is exhausted at the beginning, so dilution can nourish the stomach, the ancients mostly boiled juice decoction, but also take it to regulate the stomach, facilitate urination, go to dampness and heat. ”

Studies have shown that the rice oil of fresh rice has a protective effect on the gastric mucosa and is suitable for patients with chronic gastritis and gastric ulcers, while the rice oil of stale rice that has been stored for too long has an ulcer-causing effect. Therefore, the rice used in porridge must be high-quality new rice, otherwise, the nourishing effect of porridge oil will be greatly reduced.
