Can I eat food left overnight?
We often say that food is the main food in China. Three meals a day are inseparable from food, so sometimes, there may be leftover food. Some people will put the food in the refrigerator to refrigerate until the second day. When the weather is hot, reheat it and continue eating, which also maintains the good habit of thrift.
Especially when summer is here, many foods will be affected by some effects during storage, either due to temperature or environmental effects, causing them to rot.
So most people store food in the refrigerator, which is what we call overnight food. What about overnight food, does it mean food that has only been stored for one night? To be precise, overnight food is food that has been left out for more than 5 to 8 hours.
So can food still be eaten after 5 to 8 hours? Will certain bacteria be produced?
Can we eat overnight water, overnight meat, overnight meals, and overnight watermelon?
[Overnight water]
"Water" is what we often drink. In order to facilitate drinking water, some people will boil a large bucket of water in advance and put it in a pot to cool it. After the temperature drops, It is convenient for people to drink, and sometimes a large amount of water will be left, which will be consumed twice by people.
The process of boiling water As the water continues to be boiled, the number of times continues to increase. The nitrite content in the water is slightly higher. The longer it is left to stand, the longer it is left overnight, the nitrite content in the water will also gradually increase. Increase.
The longer it is left, the higher the nitrite content will increase. However, most water sources have passed national standards and the nitrite content in the water will not significantly exceed the standard.
To a certain extent, there will be no problem if the boiled water is left for 24 hours. If it is stored properly, it will not have any impact on the body if it is left for 48 hours.
[Overnight Meat]
The meat itself will carry some bacteria, germs and pathogens. After cooking at high temperature, the bacteria in the meat will gradually dissipate, and the bacteria carried will also be slowly reduced. The safety of the meat is also relatively high.
However, for raw meat, a large number of bacteria and germs will breed within a few days. If the meat is cooked, the original bacteria in the roasted meat can be effectively killed. Relatively speaking, this method It is relatively safe.
When the preserved roasted meat is cooked, it will be heated at high temperature for a long time, and the bacteria that breed will be constantly eliminated. The heating of cooked meat is usually much gentler, and more bacteria have been produced and will not be killed. Death is more dangerous.
When buying meat, try to buy as little as possible, and try not to store it for a long time to avoid the continuous growth and reproduction of bacteria. Meat that has been left overnight will not produce too many harmful substances. It must be heated thoroughly when eating to reduce some bacteria. and the growth of other substances.
[Overnight meals]
Overnight meals appear most often in daily life. Unfinished meals are stored in the refrigerator. After being left overnight, they become overnight meals. Then, there are some overnight meals. Is it a certain hazardous product? Will it harm our health?
"American Food Expert" conducted an experiment on this item:
He put the lunch meal in the refrigerator and took it out to eat again at night. After testing, it was found that there was no growth of bacteria and no nitrite content.
html When vegetables are stored at room temperature below 125°C, after more than 6 hours, although the nitrite content is not high, considering the proliferation of some microorganisms, it is best to store lunch at room temperature and heat it or not eat it at night.
Overnight dishes can be eaten normally, but during the eating process, everyone should pay more attention to eating less overnight dishes. If you want to eat them after putting them in the refrigerator, you must fully heat them to effectively kill the bacteria in the overnight meals.
[Overnight Watermelon]
Summer is the best time to eat watermelon. In order to relieve the heat, most people will buy some watermelon to eat. The taste is also relatively crisp and delicious, and to a certain extent, it lowers their own body temperature. At the same time, it can also provide the body with sufficient water.
Anhui Market Supervision and Administration Bureau, can you eat watermelon overnight? Certain tests and experiments were carried out.
Cut the watermelon into pieces and place it in 4℃ and 30℃ environments. Test the total bacterial content for 5 hours, 10 hours, 15 hours, 20 hours and 25 hours respectively.
test results: Whether it is placed in the refrigerator or effectively stored with plastic wrap , within 5 to 10 hours, the total number of bacteria reaches 20 grams, and they continue to reproduce from 15 hours. After 25 hours, Bacteria multiply in large numbers.
From the results of this experiment, we know that you can eat it with confidence whether it is in the refrigerator or outdoors within 5 hours, but within 5 hours, bacteria will continue to multiply. It is recommended not to eat it. After cutting, if If it exceeds 16 hours, it is recommended to fully cover it with plastic wrap.
If it has been stored for a long time, it is recommended that you do not eat watermelon overnight, as it can easily cause abdominal pain and diarrhea.
——What effects will overnight food have on the body?
[1] Overnight green vegetables
Generally speaking, the nitrite content contained in the commonly seen spinach, celery, etc., as well as stem and leaf vegetables is very high. If we buy such vegetables and store them in the refrigerator until they are finished, or store them in isolation, they will not only be nutritious, but will also produce a large amount of nitrite.
If you accidentally eat such green leafy vegetables, it can easily cause certain harm to our body, and food poisoning is also very common.
[2] The dangers of overnight seafood
Eating seafood overnight is very harmful to the body. Many seafood, such as crabs, fish, and shrimps, cannot be eaten overnight. After these foods are eaten overnight, a certain amount of protein will be produced. , the degradation products will cause certain damage to liver and kidney functions.
When buying seafood, be sure to eat as much as you want. Do not buy in large quantities. Eat as much as possible after buying to avoid the phenomenon of overnight seafood. #爱乐health#
