Why do southerners love to eat sour food?

Two days ago, a friend sent me a box of snail noodles in the south, saying that people sell it well, it must be delicious, I was quite happy, I cooked it that day and ate a bag, to be honest, it was the first time to eat snail noodles when I grew so big, the taste was weird when I cooked it, after cooking it out, I ate a bite, the taste was really unimaginable, it was too weird, it was sour and smelly, I doubted whether it was bad, and then I learned that the snail noodles in the south are this taste, sour and sour and smelly, in fact, the powder is good, It's just that the taste of the sour bamboo shoot bun in the middle is sour and sour, and many northerners can't enjoy this taste, and it's not as delicious as the sea buckthorn juice in the north, sweet and sour.

I can guess that the appearance of sour food must have been an accident. According to the analysis of modern food science, the root cause of food spoilage and the formation of sour flavor is microorganisms. It's just that some of them make you tummy, and some of them don't.

In this process, human beings who do not have modern refrigerators have keenly grasped that some of the original fermented food can still be eaten, and will not have stomach troubles. Slowly, a diet and a fixed fermentation process were formed.

It's delicious, there are many very distinctive sour and smelly delicacies in southern China, such as snail noodles, stinky mandarin fish, stinky tofu, sour soup and so on. Because it has a unique flavor that "smells bad and tastes good", it is loved by many people. Especially in the Jiangnan region, Shaoxing, Ningbo and other areas in the plum rain zone are very popular.

I'm from Hebei, and I don't know, there are only a few people in the north who can accept durian, let alone this kind of food, and those who have eaten it say that they want to vomit when they smell it.

It's delicious, there are a lot of sour and smelly delicacies in the south of my country. They "smell bad and taste good", and are loved by many people, especially in Shaoxing, Ningbo and other areas in the plum rain zone.

The south is rainy and humid, and food preservation is relatively difficult and more perishable. The emergence of the sour food process has greatly extended the preservation time of food, and with the change of the times, these sour and smelly foods have slowly become a local specialty.

This kind of food is both nutritious and has a special flavor, although it is a sour food, but it is delicious, so we like to eat it.

Because it smells bad and tastes good. I don't understand why you find it hard to swallow, but it tastes really good.

Of course, I like to eat because it's delicious, and I don't even look at it if it's not delicious.

The so-called sour food is strictly speaking, fermented food. Fermentation is the process of converting starches and sugars in food into acids so that they can be preserved for a longer period of time. Microorganisms involved in fermentation grow at low temperatures, high moisture, and high acidity, and prevent harmful organisms from destroying food.

Not only do these beneficial organics help keep food fresh, but they also have many health benefits, including improved digestion and absorption, and boosting immunity.

Fermented foods are relatively low in calories, so they don't give too many calories to people who want to, so they help. Moreover, in the process of fermentation, some active ingredients are retained, such as foods such as dietary fiber and polysaccharides, which have many benefits to the human body, can decompose some bad factors of people, and can help us get healthy.

In fact, it is not smelly, it is another form of food, there are many beneficial bacteria to the human body after fermentation, and the weather in the south is relatively humid, so people also process food in order to adapt to this climate. Not only are they rich in multi-probiotics, but they can also be appetizing to improve people's appetite. The raw materials of sour and smelly food mainly come from three main categories:

Legumes and their products, animal foods, vegetables and fruits. Under the action of microorganisms, the proteins and sugars in the raw materials are decomposed into small molecule amino acids and organic acids that are easy to digest and absorb, and at the same time produce unique odorous substances - ammonia odor and hydrogen sulfide. Taking stinky mandarin fish as an example, under the action of microorganisms, it will produce a large number of flavor substances, the most important ones are short-chain fatty acids, alcohols and aldehydes, such as propionic acid, butyric acid, n-butanol, etc.

In addition, the content of sulfur-containing compounds such as trimethylamine, indole and methyl mercaptan also increased significantly. Studies have also found that the content of essential amino acids in stinky tofu is close to that of eggs and milk, and some amino acids are even higher than those of eggs and milk. Microbial fermentation provides a characteristic flavor, but it also has certain safety risks.

During the preparation process, food will inevitably be contaminated with miscellaneous bacteria. For example, traditional fermented soybean products are easily contaminated by fungi, and the main ones detected are mucor and penicillium, which can produce some toxic metabolites and have a certain carcinogenic risk. There are many bacteria involved in the fermentation process of stinky mandarin fish, mainly lactic acid bacteria, but they are also often accompanied by some bad bacteria, such as Enterococcus faecalis, Bacillus subtilis, Bacillus cereus, etc., which need to be cooked thoroughly when cooking. In addition, most of the sour and smelly delicacies are made at room temperature, and the growth and reproduction of microorganisms are relatively fast, which also increases the risk of food safety.

In addition, most of the sour and smelly food is produced and sold in some traditional workshops, and the control of production process conditions mainly depends on experience, and it is difficult to ensure hygiene, safety and quality. Although sour food is healthy and delicious, its hygiene, quality and safety are difficult to control, and there are no relevant standards and regulations. Therefore, consumers should choose some safe and reliable stores when buying, and try to avoid buying from small vendors who do not have food hygiene licenses.

People like to eat sauerkraut and stinky tofu because of the previous habits, people used to pickle or dry vegetables for a long time, so they gradually formed a sour taste, but now life has changed, and the sour food culture is not so obvious.

Actually, it's not that I love to eat, in fact, these things are stored. You have a lot of this food that is easy to store. Sour like some he is just a snack, and as some ingredients put just an adjunct.

The climate in the south is relatively hot, so they prefer to eat sweets or cool acidic ones. Sichuan people like to eat spicy hot pot, Hunan people eat chili peppers, and northerners like to eat green onions, garlic is the same, which is a custom. Since it is food, it will have its nutritional value.

Now everyone is demanding a good taste, and everyone is overnourished.

Why do southerners love to eat sour food? Do they have any nutrients? Because they also have nutrition, they also have nutrition to make that thing, and if they don't have nutrition, they don't eat it, and there are also things that promote stomach peristalsis or something, swimming.

One side of the water and soil to raise one side of the people, the products of different places are also different, and the climate is different, such as Guangxi Guizhou is rich in rice, the climate is hot and humid, their diet is mainly rice and rice products, the taste is mainly sour and spicy, sour, appetizing, spicy. Go damp.

Sour and smelly food, I immediately thought of hot and sour noodles, stinky tofu, and snail noodles. The nutrition of sour and smelly food, first of all, they contain acid, that is, vinegar is used, which in addition to enhancing the taste sense, can also play an appetizing role. Secondly, it is their combination that can make people eat freely.

Caused by different tastes. Other people may find the food sour and smelly, but people who like to eat sour like sour food, such as stinky tofu, people who like it don't feel stinky, and people who don't like it can't even accept the smell. There are many foods with acid, and nutrition depends on what kind of food it is.

Because the climate in the south of you is very humid and the temperature is quite high. Eating a little sour food is good for yourself, and it can eliminate moisture from your body. Maintain good health.

That's because of the customs, weather and climate influences of each place, for example, eating sour food in summer can be appetizing, and stinky tofu can be said to taste very fragrant in example, and it is because the southern weather is hot and soy products are not easy to preserve, so this way is used to preserve tofu.

I think that those sour foods have no nutrients at all, and there are a lot of bacteria, and only when the food is spoiled will the sour taste occur, and this kind of food can't be swallowed.

It is because the south is hot, and the hot time is relatively long, people often have no appetite to eat in summer, because of the heat, so they like to eat some sour food to arouse their appetite and increase their appetite.

Eating sour food has a certain nutritional value, people eat more acidic food, can speed up the body's absorption of trace element iron, because in a slightly acidic environment, ferric iron is easy to convert into ferric iron, ferric iron can be dissolved in water, easy to be absorbed and utilized by the human body. After the human body absorbs the rich trace element iron, it can promote the formation of hemoglobin, which can prevent and alleviate anemia. In other words, people eat more acidic foods and have a good preventive effect on anemia.

Why do Southerners like to eat sour things? Because of the first sauerkraut, we ate appetizers, so she likes it very much, and there is no nutrition, and there is a stinky tofu, but it is also an appetizing thing, so many of us like to eat, and we don't have much health, but these things are to help ourselves appetize and digest, so many people.

Southerners eat sour and smelly food, and the southern geographical environment has a relationship, the southern weather is humid, eating sour food has many benefits, can regulate the stomach, promote digestion and absorption of the stomach, reduce the pressure of the stomach, regulate the blood circulation of the human body, but also to provide enough energy for the human body, increase appetite, make people energetic, motivated.

Sour smell is also a local specialty of the food, nutrition with the length of processing time has a loss of good taste, but not suitable for everyone to eat

This is because the weather in the south is dyed in the weather of the south, which belongs to the hot and humid weather basically does not put food for a long time, because it will be corroded, and the sour food is actually produced because of this, it can prolong life, especially can be put for a long time, like the meat and sauerkraut These are foods that can be placed for a long time, and can be eaten well until the night.
