Yeast is carcinogenic, often eating steamed bread, bread or harmful to health? Can yeast still be used? tell you the truth

“Don’t eat the steamed buns just out of the oven. The yeast of the steamed buns just out of the pot has not completely disappeared and cannot be eaten.””The freshly steamed steamed buns Steamed buns should be kept for at least two hours. When the surface temperature of the steamed buns drops, the yeast can stop developing and fermenting, otherwise it will cause some cancers in the body.”

< span>Just had a break on the weekend, Auntie Li steamed a big pot of big white steamed buns at her house, and was about to taste how it tasted, just happened to brush a short video on Zouyin, and the blogger said, “Just out of the pot. There is yeast in the steamed buns, which may cause cancer in the body.”

When I saw Auntie Li down here, I quickly spit out the steamed buns in my mouth, and forwarded this video to the family group , ask everyone whether it is true or false.

said: “We basically have fermented steamed buns with old noodles, which taste mellow and are safe and reliable to eat. Can eat.”

The child’s father said: “There are some additives in the present yeast that are harmful to health, most It’s better not to use yeast.”

Parents said: “Oh, it’s okay, I use a few After ten years, steamed buns and steamed buns are very convenient and hygienic.”

Families and friends in the group are all in Expressing her own remarks on the matter of yeast, some people agree, some people oppose it, which makes Auntie Li in trouble for a while, and she doesn’t know who to listen to.

So can the steamed buns made with yeast be edible? Will it really cause some cancer reactions to the body as the video says?

Do you know how yeast works?

In general, yeasts ferment in an aerobic environment, breaking down sugar into carbon dioxide and water, and in our Able to grow rapidly, in the absence of oxygen, yeast will break down sugar into alcohol and carbon dioxide, making the flour more swelling.

Yeast is a single-cell adhesion, and the microbial morphology is generally composed of other shapes such as oval, oval, spherical, sausage-shaped, lemon-shaped, etc. , is 1-2 times larger than a single cell of bacteria, and most yeasts are between 1-5 or 5-25 microns.

Yeast is in the shape of boundless hair and cannot swim casually. Yeast is a typical eukaryotic cell internal molecular structure, with cell membrane, Cell wall, nucleus, cytoplasm, vacuole, mitochondria, etc.

Yeast is carcinogenic and often Eating steamed bread, bread or hurting your health? Can yeast still be used? Tell you the truth

1. Experts point out: Don’t believe the rumors on the Internet, yeast ash is purely carcinogenic rumor.

Yeast itself, as a microorganism, is mainly used to leaven pasta in the stage of disease, steamed buns and wraps in life. All buns need to use it, and the temperature should be controlled above 100 degrees, and the yeast will lose its activity and die at a temperature above 39 degrees.

There is yeast in the steamed bread just out of the pot. Eating it will cause cancer in the body. There is no scientific basis to support such a statement. You don’t need to be too much. Worry.

2. Do foods containing yeast increase the risk of gastrointestinal disease?

Now there is also a saying circulating on the Internet. It is said that “steamed bread and steamed buns cannot be eaten immediately during the high school exam, otherwise they will cause gastrointestinal diseases.”

The reason why such a statement is spread is mainly because the carbon dioxide produced by yeast after fermentation is one of the things people are most concerned about. Biological leavening agent will generate a certain amount of carbon dioxide gas in the process of bread and steamed bread.

The fermentation and gas production capacity of yeast is formed by temperature and dough composition, and also by other external factors such as pH value.

If the temperature exceeds 60°C during the rising process, the activity of the yeast will gradually lose. It does not generate a certain amount of gas. The temperature during the steaming and baking process is significantly higher than 60 degrees Celsius, and it can even reach two or three hundred degrees.

It can be seen from this that you don’t need to worry about the carbon dioxide produced and the presence of yeast in the steamed buns or freshly baked bread. It is the presence of a small amount of carbon dioxide in food that does not cause substantial damage to the body.

In daily life, there are also some netizens who have a lot of prejudice against yeast. They do not use yeast to steam steamed buns, but choose steamed steamed buns that are fermented with old noodles. Is the practice good or bad for health?

Steamed with old noodles Steamed bread may be harmful to health

Especially for middle-aged and elderly people, habitually fermented with old noodles, as a This is a traditional fermentation method, which is convenient and simple. However, with the results of medical technology and scientific and technological research, it has been found that using the method of steaming steamed buns by Laomei has certain risks from the perspective of health.

Old noodles will breed a lot of bacteria and viruses after long-term storage. During the fermentation process of thin noodles, bacteria will continue to breed. Contaminate the new noodles, so the steamed buns will increase the risk of other diseases in the human body.

On the other hand, the fermented noodles with old noodles usually have a certain sour taste due to excessive fermentation, and the steamed buns have a poor taste. And high hardness.

In order to neutralize the sour taste in the noodles, some elderly people will add appropriate alkali to neutralize the taste, but the alkali But the flour will destroy the flour, resulting in vitamin B, resulting in loss of nutrients.

From the perspective of health and nutritional value, it is not recommended that you use old noodles to ferment steamed buns, it is best to use fresh yeast, and Less alkaline surface, to a certain extent, can prevent the loss of nutrients.

Yeast storage time comparison Long, will it produce harmful substances to the human body?

It is impossible to make foods like steamed buns often, and most families may store a lot of yeast when they buy them. If you store it at home for a long time and then take it out for use, will the yeast left for a long time have some adverse effects on the body?

Yeast powder is like a modern technology adopted by common probiotics. If it is left for a long time, it will cause some yeasts to die and lose their activity. Yeast does not bring certain losses to the human body.

It’s just that after the yeast fails, the flour will lose its fluffy activity and the fermentation will be unsuccessful. When buying yeast, you should store it in a dark place. A dry, dark and ventilated place can properly prolong the yeast activity and make the dough more swollen.

Secondly, I would like to remind everyone here that baking powder with similar functions to yeast will contain certain heavy metal elements, especially aluminum Atoms, if left for too long, aluminum will undergo a certain oxidation reaction with oxygen to form aluminum oxide.

The entry of such special substances into the human body will bring certain hidden dangers to the health of the body. We must identify them in time to avoid causing certain damage to the body. Influence, and the baking powder that has expired or been stored for too long cannot continue to be used.
