In fact, there are all kinds of dust, bacteria, and fungi in the air and water around us. After the steamed hair mold, the abnormally colored spots distributed on its surface are actually a fungus called Aspergillus. Aspergillus is composed of vegetative hyphae and aerial hyphae, and the nutrient hyphae are distributed inside the steamed bread and are not easy to identify.

However, if you break the steamed bread and find that the steamed bread is a little sticky, it is a nutritional mycelium, which is responsible for decomposing the sugars in the steamed bread and providing the growth of mold; The aerial mycelium is distributed on the outside of the steamed bread, that is, the surface of the steamed bread shows abnormal color spots such as cyan, black, and brown.

How to preserve steamed buns.

Aspergillus is composed of two parts: aerial hyphae and vegetative hyphae.

That is the vegetative hyphae of Aspergillus, which penetrate deep into the inside of the steamed bread and break down sugars for the mold to grow.

In the summer, because the weather is hot and humid, this is good for mold growth. Therefore, food is particularly prone to mold and spoilage in summer.

Summary. Hello, steamed steamed buns with moldy spots for ten minutes can't be eaten. Some molds and their toxins are prone to cause food poisoning after ingestion, for example, aflatoxins are hepatotoxic, long-term ingestion of small amounts can cause subacute and chronic damage, it is one of the recognized carcinogens, aflatoxins are heat-resistant, and their toxicity can only be eliminated when the temperature reaches 280, in addition, penicillin and certain toxins produced by Fusarium may cause food poisoning.

Hello guess, you can't eat moldy steamed buns for ten minutes. Some molds and their toxins can easily cause food poisoning after ingestion, for example, aflatoxins are hepatotoxic, long-term ingestion of small amounts can cause subacute and chronic damage to spike ruiming, it is one of the recognized carcinogens, aflatoxins are heat-resistant, and their toxicity can only be eliminated when the temperature reaches 280, in addition, penicillin produced by Fusarium and some withered toxins may cause food poisoning.

Even if the steamed bread has moldy spots, it cannot be eaten, and the moldy spots generally indicate the presence of mold. Steamed bread contains more carbohydrates, which can provide certain nutrients and a suitable environment for the growth and reproduction of mold, so the growth and reproduction of mold in steamed bread is usually faster and will spread rapidly on the outside and inside the pin. The mildew visible to the naked eye, such as mold spots or odors on the surface, indicates that the mold hyphae are fully developed and usually have toxins.

There are also some molds that are not yet mature, and the immature molds and toxins cannot be seen with the naked eye alone. Therefore, even if it is steamed thoroughly in a pot, absolute hygiene cannot be guaranteed. If you eat steamed buns with moldy spots, it may cause acute gastroenteritis, resulting in abdominal pain, diarrhea, vomiting and other uncomfortable symptoms.

Usually the maximum temperature of the steam is 100 °C, and this temperature may not be reached at times. The temperature at which mold is killed is usually high, such as Aspergillus flavus, which cannot be completely removed even if it is heated at 100 degrees Celsius for 20 hours, and can only be destroyed at a high temperature of more than 280 degrees. Therefore, it is not possible to completely remove mold under steaming conditions.

It is generally recommended to eat fresh steamed bread, and even if there is any leftover steamed bread, it should be sealed and stored in the refrigerator for refrigeration, and try to eat it within 1 week.

Mold is a common natural phenomenon, mostly appearing in food, food contains a certain amount of starch and protein, and more or less contains some water, and mold and insect eggs need the presence of water and warm temperature for growth and development.

Mold and eggs cannot absorb water when the water activity value is low and when the water activity value is increased after moisture, the mold and eggs will absorb water from the food and then decompose and eat the nutrients in the food. At this time, foods such as steamed buns will become moldy.

In daily life, foods that are more likely to become moldy mainly include: rice, peanuts, corn, grain-processed pastries, rice, steamed buns and other cooked foods.

The higher the temperature and humidity are within this range, the easier it is.

The steamed bread we eat daily is a fermented food that uses yeast as a carrier. When the finished steamed bread is exposed to certain external conditions (temperature and humidity), over time, the yeast attached to the surface will be transformed into mold, and over time, this mold will also penetrate into the inside of the steamed bread. This is the process of steamed bread mildew.
