Room temperature 5 degrees Is it OK to eat leftover rice from yesterday today?

If the temperature is low, the overnight rice must be edible, but the favorite thing to eat is not noodles but rice, from childhood to adulthood, every time my mother asks me what to eat at noon, I will always say eat rice without hesitation, rice is really my love, from snacks to big I have never been bored of eating.

Of course, when I say that overnight rice can be eaten, it's not because I like to eat rice, it's based on science, and there are some potential benefits to not only eating it, but also the potential benefits, so let's talk about it in detail. Not to mention the starch that is the main ingredient of rice, everyone must know that when the starch is heated above 53 degrees Celsius, the starch grains will slowly dissolve and expand, and finally form a viscous and uniform paste, this process has a name, that is, starch gelatinization.

The gelatinized starch has a better taste, it will become more delicious in many aspects such as viscosity, toughness, strength, etc., and at this time, it is also more likely to be hydrolyzed by the amylase secreted by the mouth, and then absorbed by the body in the form of glucose. However, after gelatinization, the starch will also be aged after cooling, that is, the rice grains will become very hard after cooling, and then a large part of the rice grains will be transformed into "resistant starch", and there are also other names called enzymatic resistant starch or indigestible starch, which are usually things that cannot be digested in the small intestine.

Even if the starch is reheated, even if the temperature is particularly high, it will not return to the molecular structure it had when it was first gelatinized. It may sound like overnight rice is terrible, but it's not, so keep listening. Because the aging rice is difficult to digest in the body, it is relatively slow to absorb and enter the blood, which has a similar effect to dissolved fiber, which not only overcomes the shortcomings of the staple food that rises blood sugar quickly, but also stabilizes blood sugar, and at the same time, because it is not easy to absorb, it also has a certain effect.

However, the words are divided into two ends, and it is precisely because it is not easy to digest, so people with poor gastrointestinal function, or the elderly and children with weak digestive function, it is best not to eat or eat less rice that is reheated after overnight So how should the overnight rice be kept and heated? Teach everyone. For hygienic reasons, it is necessary to be careful in the handling of overnight meals.

First of all, the leftovers should be loosened, put in a ventilated and cool place, and when the temperature naturally drops to room temperature, cover it with plastic wrap and put it in the refrigerator.

The room temperature is 5 degrees, and the leftover rice from yesterday can be eaten today. If it is 5 degrees, it should not be broken.

Advocate eating fresh meals, rice will be polluted for a period of time, spoiled, high temperature weather is more prone to spoilage, the next meal is generally no problem, yesterday's rice is better not to eat as well, the problem outweighs the loss!

The rice will not go bad overnight at room temperature 25 degrees. Although the water content and nutrients of rice are very suitable for bacterial growth, it is not conducive to the growth of bacteria because of the lack of flora at room temperature of 25 degrees, so rice at room temperature 25 degrees will not spoil overnight.

If the rice is not completely cooled, you can place it on a dining table or in a ventilated place until it is completely cooled before putting it in the refrigerator. The purpose of fluffing the rice is to allow the rice grains to cool down faster, and at the same time, most of the water vapor can be evaporated and lost.

Leftover rice will become hard if it loses moisture, but the moisture generated by heat can easily spoil the rice. The rice will not form lumps when it is used next time, and it will be easier to stir the rice when it is still warm, and if it will become hard after cooling, especially after refrigeration, it is not easy to let the rice grains spread out.

It usually won't spoil in six hours, but it's best to keep it in the refrigerator.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature state. Inside the box there is a compressor, a cabinet or box for ice making for icing, and a storage box with a refrigeration unit. The volume of a household refrigerator is usually 20 500 liters.

In 1910, the world's first compression-type refrigerated household refrigerator was introduced in the United States.

In 1925, the Swedish Lido company developed the household absorption refrigerator.

In 1927, the General Electric Company of the United States developed a fully enclosed refrigerator.

In 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market.

In 1931, a new type of refrigerant freon was successfully developed, and the production of household thermoelectric refrigerators began in the second half of the decade, and China began to produce refrigerators in the 50s.

All food will not spoil at 30 degrees Celsius for 6 hours after the first cooking, provided that it needs to be closed when it has just cooled, such as plastic wrap.

Because the food forms another stable state after the first cooking.

If the temperature is relatively high in summer, it will basically deteriorate in 3 hours, but if it is in other seasons, it can be stored for 24. However, it is not recommended to keep the temperature for 6 hours, which will cause the load pressure of the rice cooker to increase, a short circuit, and a fire.

Can you eat rice if it has been steamed for too long in a warm temperature?

One rice and three meals are indispensable, and in the southern region of our country, it is basically inseparable from rice, steaming rice is relatively simple, you only need to wash it with water several times, and then put it in the rice cooker to simply steam for half an hour, and some rice cookers will automatically jump to the heat preservation mode after steaming the rice, how long can it be stored in this case?

In fact, the time it takes to keep rice warm is affected by the temperature, if the temperature is relatively high in summer, it can be stored in a warm environment for 3 hours, and in other seasons, it is no problem to put it for 24 hours, and if the temperature is high, the food will be extremely easy to spoil, and it will affect the body after eating.

It is generally not recommended to keep the rice warm for 6 hours, because if you use a rice cooker, plugging it for 6 hours will cause the load pressure of the rice cooker to increase, and it is very likely to cause a short circuit, and it is easy to cause a fire when the weather is dry.

The rice can be eaten overnight at 20 degrees Celsius.

Rice is generally made from rice and is rich in protein and carbohydrates.

Therefore, it is easy to be fed by bacteria, and in an environment of 20 degrees, the growth rate of bacteria is relatively slow, so it can be eaten after storing it overnight.

The main ingredient of rice is carbohydrates, and the protein in rice is mainly rice prominin, amino acids.

The composition is relatively complete, and the human body is easy to digest and absorb. Minerals, dietary fiber, B vitamins (especially vitamin B1) in brown rice

The content is higher than that in polished rice, but the lysine content in rice is lower.

Yes, but not too much.

Heat-processed foods usually have some vitamin loss, and the higher the temperature and the more times they are heated, the more vitamins are lost. Studies have found that leftovers are difficult to digest after being reheated, and may cause stomach problems over time.

Digestive enzymes in the human body hydrolyze this gelatinized starch molecule, and when the gelatinized starch cools, it produces an "aging" phenomenon. If the aged starch molecules are reheated, it is impossible to return to the molecular structure of gelatinization, even at high temperatures. The body's ability to hydrolyze and digest this aged starch is greatly reduced.

Therefore, long-term consumption of this reheated leftovers is prone to indigestion and even leads to stomach problems. Moreover, the digestive ability of the elderly becomes weak, infants or infirm and sick people suffer from gastrointestinal diseases, it is better not to eat or eat less cold meals or meals that have been cooled and reheated.

I can eat it, and I can rest assured. Because it has been kept warm, it means that the rice has been at a high temperature, and bacteria cannot invade, so the rice will not deteriorate and has no effect on health!

After cooking, the rice is left to keep warm for 24 hours overnight, and as long as it is not bad, it can still be eaten. It doesn't matter.

Cooked rice. Put it in the incubator, you can still eat it for 24 hours, as long as it is. Rice no? It's okay not to ask.

Overnight, it seems, has become a magic term. Delicious dishes become toxic overnight? Nitrite exceeds the standard after boiling boiled water overnight?

Can't eat rice overnight? In this way, it seems that overnight has become a "magician", no matter how healthy the food is, when it encounters overnight, it can only be caught with its hands tied and become a "**" that murders health.

Today's main thing with you is the last question, can you eat overnight dinner?

Rice is a staple food every day, and sometimes if you accidentally cook too much, it will inevitably be wasted if you throw it away, so you will think about staying and continuing to eat it tomorrow. Especially for office workers, ordering takeout at noon is expensive and unhealthy, and it is better to cook more meals the night before to take to the company for lunch the next day.

There are a lot of opinions on the Internet about overnight rice. Some people say that overnight rice can cause cancer; Some people say that overnight rice is not nutritious; Some people say that overnight rice is not good for the stomach. So which statement is true? What is the difference between overnight rice and fresh rice?

To put it simply, overnight rice is fresh rice that has been left out for a long time, and the two are the same ingredients. Outwardly, there is no significant difference between the two; On the palate, overnight rice will be slightly sticky and slightly less flavorful; In terms of nutritional value, overnight rice is also slightly worse.

The composition of rice is starch, which is broken down into maltose and then glucose after entering the human body. Starch will gelatinize at a high temperature of 60 °C, and aging will occur after cooling. Aging is an irreversible process, and even if the rice is heated later, it is impossible to return to the molecular structure of gelatinization.

As a result, even if the overnight rice is heated, it still tastes much worse than before.

It is true that the bacterial content of overnight rice will be higher than that of fresh rice, but it is still far below the pathogenic standard, and the proper storage method can greatly inhibit the growth and reproduction of bacteria.

Before storing overnight rice, wait for it to dry before putting it in the refrigerator, as bacteria are more likely to grow in humid environments. The refrigerator is a low-temperature environment, which helps to inhibit the growth and reproduction of microorganisms and can minimize the amount of bacteria in overnight rice. However, it should be noted that if the rice has been poured with vegetable juice, it is recommended to solve it as a meal, because vegetable juice contains nitrite, which will oxidize the low hemoglobin in blood cells to methemoglobin, which may cause cell cancer.

The storage time of overnight rice should not be too long, even if it meets the low temperature and dry environment, it should be solved as soon as possible, try to shorten the time to 5 or 6 hours, and at most it should be eaten the next day, not several days.

You can continue to eat it, referring to the egg fried rice used to be overnight rice.
