We will inevitably have leftovers that we can’t finish
For these leftovers
It’s time to eat
It is usually eaten after heating
But you know what
Some foods cannot be reheated
It’s better to throw it away
Blind savings is no good
There may also be many hidden dangers to the body!
Which foods cannot be reheated?
What should we do with leftovers?
The editor will take you to find out!
It’s best not to reheat these foods
One, mushroom food
Mushrooms are the first thing that comes to mind when you think of mushrooms. Mushrooms will produce a lot of nitrates after being cooked at high temperature. Nitrate levels will continue to increase. Often eating mushrooms after the second heating may cause abdominal pain, diarrhea and other symptoms. Eating this way for a long time will increase the probability of suffering from digestive system tumors. Therefore, it is not recommended to continue eating mushrooms after the second heating. Lose.
Second, seafood food
Shrimp, crab, sixty-six and other seafood are not suitable for secondary heating. If uneaten seafood is left for too long, it is easy to breed bacteria and produce toxins, and the usual heating time and temperature are difficult to kill and eliminate these bacterial toxins , Increase the detoxification burden of the liver, it is best to make it now and eat it.
Three, spinach
Spinach is high in oxalic acid and needs to be blanched before consumption. In addition, spinach also contains a large amount of nitrate. If it is heated again, the spinach will be converted into nitrite due to reheating, which is harmful to the human body.
Four, milk
Milk cannot be heated repeatedly, it will deteriorate over time, which will breed bacteria and easily cause diarrhea. In addition, repeated heating of milk will denature the protein in the milk, resulting in a lack of nutrients. Commercially available boxed and pouched milk are sterilized or sterilized and can be consumed directly or heated. It does not need to be cooked through or reheated.
V. Tremella soup
Because white fungus contains a lot of nitrates, if the boiled white fungus soup is left for too long, the nitrates will be decomposed and reduced to nitrites. Nitrite will make the hemoglobin in the blood lose its ability to carry oxygen, thereby destroying the normal hematopoietic function of the human body and affecting health. So Tremella soup is best to drink now, not overnight.
Six, fluffy eggs
Boiled eggs mainly refer to undercooked eggs, so the boiled eggs cannot completely kill the salmonella in the eggs. If left for another night, it increases the chances of bacteria multiplying and producing toxins. Even if it is cooked a second time, there is a risk of disease and it is best to avoid it.
Occasionally eating loose eggs in small amounts may not cause obvious harm to human health. However, if there is excessive consumption or frequent consumption of loose eggs, it may cause gastroenteritis, abdominal pain, diarrhea, nausea and other symptoms, and food poisoning may occur in severe cases.
It is best to eat fully cooked eggs, so as to eliminate all the bacteria inside. Fully hard-boiled eggs are stored at low temperature and in an airtight condition, and are generally stored for 48 hours without problems.
How to properly treat leftovers at home?
First, treat leftovers with a “rigorous” attitude
The fourth point in the “Five Points of Food Safety” proposed by the World Health Organization, “Maintaining a safe temperature of food”, clearly recommends that cooked food should not be stored at room temperature for more than 2 hours, and should be refrigerated in time (preferably below 5°C) , do not store in the refrigerator for more than 3 days, and the leftovers should not be reheated more than once.
Second, be smart about leftover food, preferably “only meat and no leftovers”
Compared with meat products, vegetables will produce more nitrite during storage, and will also lose a larger part of nutrients (vitamin C, etc.). On the whole, it is recommended that circle friends “really want to have leftovers, try to leave meat and not vegetables”.
Also, leftover cold dishes are not recommended. Cold dishes are generally not heated, which is more likely to breed bacteria and other harmful substances, which will induce food poisoning problems such as diarrhea and abdominal pain.
Three, the storage of leftovers should be “scientific”
In order to ensure the “sanitation and safety” of leftovers and leftovers, it is recommended to avoid “unnecessary operations” on them.
Reduce the flipping of leftovers with chopsticks and other utensils, and use safe and reliable fresh-keeping boxes to store and store leftovers to ensure their airtightness.
The leftovers should be stored in the “low temperature area of the refrigerator” and eaten as soon as possible to avoid the proliferation of bacteria and other microorganisms.
It is worth noting that leftovers need to be “sorted and packaged + stored” to avoid cross-contamination and odor.
Four, leftovers must be “heated through” before eating
While leftovers can be eaten, be sure to “fully reheat” them before eating. That is, leftovers should be heated to 100°C and kept boiling for at least 5 minutes.
Five, how much to eat, how much to heat, do not “repeated heating”
In order to reduce the risk of microbial invasion and avoid food poisoning incidents, it is not recommended to repeatedly heat leftovers and leftovers. Eat as much as you can, and heat as much as you like. The rest of the food is kept in the refrigerator and eaten as soon as possible.
