Northerners like to eat pasta, such as steamed buns, flower rolls, pancakes, pies, dumplings, etc., which are common on the table every day.
But for those who want to eat soft and porous steamed buns, they don't know how to make them, buy them back and store them in the refrigerator, I heard that the storage time can not exceed 3 days, otherwise it is easy to produce aflatoxins and increase the risk of carcinogenesis?
Put steamed buns in the refrigerator, don't exceed 3 days?
In fact, there is no such time limit, for steamed bread, a high-carbohydrate staple food, it is indeed easy to breed aflatoxin, if the steamed bread is placed in the refrigerator, it will not lead to the production of toxins in a short time.
But as the storage time gets longer and longer, when you see green mold and black mold on the steamed bread with the naked eyeIt is most likely aflatoxin, which is a secondary metabolite produced by toxin-producing strains such as Aspergillus flavus and parasitic molds, and is a highly toxic substance.
For example, aflatoxin B1 was found to be one of the strongest chemical carcinogens in the available data and was classified as a Group 1 carcinogen in the World Health Organization's International Agency for Research on Cancer. In other words, in daily life, not only steamed bread is easy to be hit, but also rice, milk, edible oil, soybeans, corn, etc., have been found to have aflatoxin.
It should not be underestimated that once everyone consumes such food,It is extremely toxic to the health of the body, and is the most harmful to the liver of metabolic organs, such as vomiting, anorexia, fever, ascites, jaundice, etc., and the risk of liver hemorrhage, hepatitis, liver cirrhosis, malformation, cancer, etc.
In order to help everyone better stay away from aflatoxins, it is recommended that everyone control their diet reasonably, ensure that the environment they come into contact with is clean and hygienic, reduce microbial pollution, and pay attention to whether the food in their mouths is moldy.
Once the appearance of the food grows yellow-green mold,That is, it is a manifestation of aflatoxin infection, even if a small part, the rest can no longer be eaten, and be prepared to remove it in time to prevent aflatoxin from being accidentally introduced to the greatest extent.
For the storage time of steamed bread, it depends on if you don't plan to eat it immediately, it is best to put it in the freezer compartment of the refrigerator, which will help extend the shelf life of steamed bread; If you buy or make fresh steamed buns on the same day and don't finish them in time, you can also put them in the refrigerator for 2 to 3 days, and it is advisable to eat them in time.
Therefore, for "steamed bread in the refrigerator, more than 3 days are prone to carcinogens?" It needs to be treated scientifically. However, for the sake of the nutritional value of the food itself, it is recommended that you do not leave it for a long time, as it is easy to lose nutrients and make the taste worse.
