Foods such as kimchi, pickled cabbage, spoiled leftovers, fermented sour pancakes, salted fish, etc., contain more nitrates (this is due to the increase in nitrates in vegetables due to the widespread use of chemical nitrogen fertilizers in recent years). When consumed in large quantities, intestinal bacteria can reduce nitrate to nitrite, which can cause poisoning. Nitrite is more toxic than nitrate.
When grams of nitrite are ingested, poisoning can occur and even cause death. This is because nitrite is an oxidizing agent that oxidizes hemoglobin in the blood to methemoglobin, which loses its ability to excrete oxygen, resulting in a lack of oxygen in the tissues. In addition, nitrite can also be combined with secondary amines decomposed by proteins to synthesize nitrosamines in the stomach, which is a strong chemical carcinogen that can cause a variety of cancers such as gastric cancer, liver cancer, and colorectal cancer.
Nitrite levels are also high in soils in areas with a high incidence of liver cancer. Studies have shown that the amount of nitrosamines in liver cancer specimens is much higher than that in normal liver. Precautionary measures:
Vegetables should be properly stored to prevent decay, and should not be eaten if they have rotted and deteriorated. Vegetables with a high amount of nitrite should be eaten after cooking. Pickled vegetables (such as pickled cabbage, etc.) should not be eaten in large quantities or too early.
Because this kind of pickled products often use insufficient salt or no salt at all, bacteria can reduce the nitrate in the dish to harmful nitrite within 1 week, and the nitrite content gradually decreases after 1 week due to the decomposition and destruction of acetic acid and lactic acid. Therefore, pickled vegetables must be pickled thoroughly, and it is best to marinate them for more than half a month before eating. Promote the consumption of environmentally friendly, nitrate-free natural green vegetables.

Bring the water to a boil first.
Then add a large spoonful of rice noodles.
Mix evenly. Be sure to stir well until there is no dough.
Let cool at this time. The process must be free of raw water and oil stars.
Then the rimmed kimchi jar should be washed in advance and scalded with boiling water and left in a ventilated place to dry.
Cut the fresh bamboo shoots and dry them on all sides.
Then put the bamboo shoots into the jar and pour the cooled rice water into the jar.
Close the edge of the lid and add water.
Wait 10 days.
A fragrant appetizer is ready.
Remember. It is best to use the chopsticks when you clip them out.
I'm afraid that the oil will break the cylinder.
I made this altar myself the year before last.
Soak until now.
As soon as fresh bamboo shoots are on the market, they will buy them back and soak them.
Remember. Don't eat all the bamboo shoots when you don't have fresh bamboo shoots to sell.
Why do you have to keep a piece to keep the tank?

It should be eaten at least seven days later.

Hello, it is a pleasure to serve you. It is generally recommended to marinate cured meat for more than 20 days before eating, but do not marinate for too long. But in the case of bacon, the bacon is generally marinated for about seven days, and then it can be taken outside to be exposed.
If you want to marinate bacon at home, you can marinate the fresh meat with your own seasoning first, so that the flavor can penetrate into the fresh meat. After a week or so, the originally white pork belly starts to turn red, and you can take it out and start drying. When it is all dried, it becomes bacon.

Meat generally marinated at home needs to be marinated for more than 20 days; Marinated bacon is generally left on the balcony or other places to dry for a few days, in fact, in general, the marinating time is generally more than 20 days, so that the salted meat can be eaten.
According to the research of experts, the nitrite content of cured salted meat is not high within 2 days of starting to marinate, but the nitrite content reaches the peak on the 3rd to 8th day, and begins to decline after the 9th day, and basically disappears after 20 days.
Therefore, the marinated bacon is generally shorter within 2 days, and the long one should be marinated for a month before it can be eaten. We usually press the bacon with a large stone or something else to prevent the bacon from losing water.

<>1. The marinating time is less than 2 days or more than 20 days. According to scientific determination, the nitrite content of pickles is not high within 2 days of pickling, but the nitrite content reaches the highest peak on the 3rd to 8th day, begins to decline after the 9th day, and basically disappears after 20 days.
2. The pickled pickles are generally shorter within 2 days, and the long ones should be pickled for a month before they can be eaten.

The second pickling process is similar to the first and is biological fermentation. The bacteria used in this fermentation process are lactic acid bacteria, which have a fresh sour taste of pickles, and the pickles they produce are exactly what we call kimchi.
We are all familiar with the third pickling method, this method mainly uses salt to pickle, which is highly operable and is very popular in many places in our country.

4-5 days. After 4-5 days of marinating, the meat can be removed and hung in a cool and ventilated place to dry. Every year from October to January of the lunar calendar, the weather is sunny and the north wind is dry.
Bacon refers to the process of meat being cured and then roasted (or exposed to the sun). Bacon has a strong preservative ability, can prolong the preservation time, and adds a characteristic flavor, which is the main difference from bacon. <

How long does it take to eat pickled radish.
Generally speaking, after the radish is sun-dried, put it in the jar to pickle, you can eat it in about a day, if the temperature is low, it may take 2-3 days, you can eat the radish at any time, because the time is different, the pickled taste is different, the longer the time, the softer it may become, not as crisp as the initial stage. >>>More
