The reason why bread has green mildew. In our daily life, bread is a snack we often eat, but the shelf life of bread is very short and it is difficult to keep. What is the reason of bread green mildew? Let's take a look together.

Is the green mold on the bread poisonous? 1 The temperature is high in summer. It is considered normal for food to go bad and rot due to long storage time. Young people are lucky enough to throw them away. Middle-aged and elderly people always have this kind of luck, thinking that they can continue to eat after removing moldy places. Today, I will talk to you about this problem.

Compared with northerners, southerners prefer to eat pasta, steamed bread for dinner and bread for breakfast. After a period of time, such staple foods often grow small green spots and black spots. In fact, this phenomenon is food mildew. From the perspective of food safety, food mildew is mainly caused by mold.

For bread, the American fun science website found that bread just began to grow long, in fact, it was to prepare for the growth of mold. The phenomenon it displays usually has two colors, one is green and the other is black.

Even if the moldy part of this kind of food is removed, or the area around the moldy part is removed and expanded by one centimeter. Where we can't see with the naked eye, mold will still exist. After middle-aged and elderly people and children with low immunity eat it, the performance of food poisoning will be more obvious. Therefore, we can't eat bread after we see that it is a little moldy. It is more important to ensure our health and prevent food poisoning.

Besides moldy bread, moldy steamed bread is also common. Whether you make it yourself or buy it outside, under the condition of mold breeding, it will penetrate infinitely and implicate the rest.

If you are used to eating steamed bread at home and eat too much at a time, don't put it in a cool and dry place. After entering the awn seed, not only the temperature is high, but also the humidity is high, which is just in line with the conditions for bacterial growth. Compared with other solar terms, bacterial food poisoning is more likely to occur. In order to avoid being affected by temperature, it is recommended that you wrap the steamed bread in a fresh-keeping bag and put it in the freezer. You can take it out and heat it thoroughly when you want to eat it.

In addition, for moldy cheese, don't think that you can continue to eat it by removing the moldy place, especially when it changes from dry cheese to soft cheese. It is likely that the mold was affected by humidity and infiltrated more bacteria.

In terms of food safety, cheese is not only easily infected by Salmonella, causing common food poisoning, such as diarrhea, abdominal distension, abdominal pain, nausea and vomiting, but also increasing the risk of acute gastroenteritis.

Also beware of Listeria, which is widely found in food, including ice cream, soft cheese, cooked frozen meat and so on. Especially after the food of pregnant women is moldy, don't eat any more. If the fetus is infected, it will easily affect their growth and development and even their lives. For safety reasons, everyone should pay attention to the preservation of food and eat it after fully heating.

Prevent mildew

In order to prevent bread from mildew, it must be kept dry or stored in the refrigerator at low temperature, so that mold is not easy to breed. Because they have (+) (-) sex distinction (just like plants are hermaphroditic), sexual zygotes of bread mold are rarely found in natural environment.

It is necessary to find different strains to mate in the laboratory in order to observe their zygotes. Because baker's mold can decompose starch, we can extract amylase and lactic acid from its colony. Another Rhizopus oryzae can be used to make soy sauce.

Breast mold can produce zygospores and conidia for reproduction.

Refer to People's Daily Online-These three foods are the most carcinogenic. Be careful!

Is the green mold on the bread poisonous? Bread is a baked food with wheat flour as the main raw material, yeast, eggs, oil and nuts as the auxiliary materials, mixed with water to make dough, and processed by fermentation, shaping, molding, baking and cooling. It is a kind of food rich in carbohydrates and protein, which is nutritious and easy to digest and absorb. It is also a good culture medium for microorganisms, so bread grade is prone to mildew during storage, especially in high temperature and rainy season. If you look at the reasons, it is mainly caused by mold, including Penicillium, Aspergillus flavus, Rhizopus and other strains.

The growth of mold needs oxygen, water, carbon source, nitrogen source and other nutrients, and it reproduces by spores. In humid environment, the optimum growth temperature of mold spores is 20 ~ 35℃. Spores have propagated on bread for at least 24 hours when mildew spots appear on the bread. In addition, the mildew of bread is not only superficial, but also sticky. Stickiness generally starts from the bread core, and the original loose porous body decomposes to become sticky and soft, and the bread core is dark, and finally becomes a sticky colloid, which produces a smell similar to melon decay, and can be squeezed by hand to form a ball; When you cut the bread, you can see white hyphae.

In fact, the bread with mildew in the early stage will have a certain musty smell, and there are spots on its surface, and the spots will continue to expand and spread to the whole crust. Bacteria can also invade the depths of bread and fill the honeycomb of the whole bread, so that the whole bread will be moldy in the end.
