Speaking of [overnight], the word “overnight” seems to have magic. If you add them to any food, it will become harmful…….
Especially in hot summer, food always has an indescribable subtle feeling every night.
Eat? Or not? Dr. Clove will tell you the answer.
You can’t eat these overnight foods?
01. Are there toxic substances in overnight water and tea exceeding the standard?
It is said that these two kinds of water will produce a large amount of nitrite overnight, endangering health.
In fact, some experimental data show that when the water boils for more than 30 minutes, the nitrite content will remain stable and there will be no big change every other night.
As for overnight tea, although its color will darken after long-term storage, the nitrite content after overnight is indeed about 2 times higher than that when it was just soaked, reaching 0.251 mg/L.
But don’t worry, the nitrite standard for drinking water in our country is 1 mg/L, and the tea after one night still does not exceed the standard, which is safe.
However, the tea is not good to drink after being kept for a long time, so try not to stay overnight.
02. Can overnight leftovers cause cancer?
Whether the leftovers can be eaten overnight depends mainly on whether your preservation method is suitable or not.
This summer, if the leftovers are left at room temperature for one night… the next day it tastes sour and refreshing!
Dr. Clove suggested:
- Try not to leave vegetarian dishes and cold dishes. Vegetables themselves have more nitrates and are more likely to produce nitrite than meat. However, cold dishes are more vulnerable to bacterial contamination. Refrigerate in the refrigerator in time. It is best to enter the refrigerator as soon as you get out of the pot. If you eat the last rest, you should also do so as soon as possible. Never wait for room temperature before refrigerating. Be sure to heat it thoroughly before eating. Whether it is meat or vegetarian dishes, the best way to sterilize is to heat it thoroughly.
03. Are there many bacteria in watermelons overnight?
Watermelon is a nutritious feast for bacteria, which can produce hundreds of thousands of offspring in a few hours, let alone overnight.
How can watermelons stay safe overnight? You need to do two things: wrap plastic wrap and put it in the refrigerator in time (watermelons can use plastic wrap, don’t worry).
- Plastic wrap can isolate watermelons from other foods in the refrigerator to avoid secondary pollution. Refrigeration in the refrigerator can reduce the activity of bacteria and make them grow slower.
Of course, from a fresh point of view, Dr. Clove’s most recommended is to buy smaller melons, wash them and refrigerate them, then cut them and eat them now.
04. Are there many bacteria in eggs overnight?
The key to the risk of overnight eggs lies in the fact that they are not boiled thoroughly. Be careful: soft-boiled eggs.
Eggs are a kind of food that is easily contaminated by bacteria. A few days ago, there was news that twins were infected with septicemia by eating raw eggs.
In fact, if the eggs are boiled thoroughly and refrigerated in time (key points are drawn), you don’t have to worry overnight, and you can even eat them for 3-4 days.
However, in order to pursue the taste, many people like to eat soft-boiled eggs that are not thoroughly cooked. Such eggs are not thoroughly sterilized and have the risk of bacterial contamination. If unlucky, it may lead to food-borne diseases.
In addition to what has been said above, whether the soya-bean milk, tremella soup and seafood transmitted online can be eaten overnight depends on whether you keep them correctly.
Changes hidden in the dark
People’s worries about overnight food are actually two words: bacteria.
Food is rich in nutrition. Overnight usually means a long storage time (8 ~ 12 hours). If there is bacterial contamination, as long as the temperature and humidity are appropriate, they will grow and reproduce rapidly, causing food spoilage and generation of toxic and harmful substances.
Therefore, the two key points to ensure overnight health are: reducing bacterial pollution and controlling the temperature.
How to make food safe for the night?
01. Reduce bacterial contamination
Containers should be clean. Containers that store overnight food are best treated, such as cooking and sterilizing with boiling water.
After coming out of the pot, it will be packed separately. The possibility of bacteria contamination is small for the dishes that have just come out of the pot. If you find that there are too many dishes to cook today, it is better to pack the extra parts as soon as they come out of the pot.
Step 02 Control the temperature
If the prepared food cannot be eaten out, it should be put into a clean container as soon as possible and put into the refrigerator as soon as it is sealed.
Don’t wait until it gets cold!
03. Don’t be careless before eating
Although the temperature of the refrigerator is relatively low, which reduces the reproduction speed of most bacteria, some bacteria are naturally not afraid of cold and can grow in the refrigerator.
Therefore, Dr. Clove suggested that cooked food should be thoroughly heated before eating, and fruits and vegetables should be cleaned or cut off before eating.
What, you said there was no refrigerator at home?
Let’s throw it away except it’s cold and white…….
