First, moldy food contains a large amount of mold, which can lead to disorganized digestive tract flora, food poisoning, and even life-threatening acute abdominal illness. Secondly, consuming moldy food can lead to significant problems due to the invasion of mold spores into the blood or respiratory tract. Third, moldy food mostly contains aflatoxin, which is a world-recognized number one carcinogen, and long-term intake of aflatoxin can lead to multi-organ cancer. Aflatoxin toxicity will cause cancer After the moldy food, not only changes the color, aroma and taste, reducing the quality of food, but also due to the direct invasion of mycotoxins into the body, resulting in lesions. In the more than one hundred kinds of mycotoxins have been found, aflatoxin is the most toxic, and the most harmful to humans. Aflatoxin is a metabolite of Aspergillus flavus, very easy to contaminate rice, corn, peanuts and other grain and oil food, its toxicity is 80 times cyanide, 100 times dichlorvos. Aflatoxin enters the body through the digestive system, it will cause acute liver lesions. It is now internationally recognized as one of the strongest chemical carcinogens, according to Africa, Southeast Asia, some countries and regions, where food is contaminated by aflatoxin serious places, the highest incidence of liver cancer. In addition, it can cause cancer of the kidney, stomach, brain and other parts of the carcinoma. Aflatoxin is very heat-resistant (up to 270 ℃ high temperature), so the general cooking process is difficult to thoroughly detoxify. Aflatoxin in the temperature of 28 ℃ to 32 ℃, relative humidity of more than 85% of the environment is most likely to reproduce and produce poison. At present, the removal of aflatoxin in grain and oil generally use alkali refining method, that is, with sodium hydroxide (caustic soda), caustic soda sodium, so that aflatoxin into sodium salt of crotonic acid, can be dissolved in water and washed away by water, to achieve the purpose of detoxification. Secondly, the use of active white clay adsorption method, that is, the use of active white clay to adsorb aflatoxin in oil to the surface pores, and the residue of white clay after the adsorption of toxins. Second, which foods are prone to produce aflatoxin? Aflatoxin generally enters milk through feed. After animals eat feed containing mycotoxins, their offal and the milk, eggs and meat they produce will also contain toxins, which will attack humans through the food chain. Milk is one of the most vulnerable to aflatoxin contamination of livestock products. In addition, do not eat the moldy food in life, even if the moldy part of the removal will not work. Aflatoxin mainly contaminates food, animal and plant food, such as peanuts, corn, rice, wheat, meat, milk and dairy products, aquatic products, etc.. Homemade fermented foods can also detect aflatoxin, especially in high temperature and high humidity areas of food and oil and products with higher detection rates. Aflatoxin may also be present in moldy pickles, a moldy peanut rice, much more than the excess aflatoxin in milk. Incomplete peanut rice also can not eat, half of the peanut rice surface is most likely to mold, although invisible to the naked eye, but actually contains a lot of aflatoxin. Third, how to determine the food mold? Judgment of food mold: a color two taste Color change is the most important and most directly observable aspect of the shape of moldy food appearance, followed by the texture. Take the more common types of moldy food as an example: moldy rice surface is light yellow, light gray or green, its texture has also become soft, easy to crush; leftover steamed buns, rice after a few days of preservation, its surface may grow gray, yellow or green fluffy mold; stored for too long pastry, its surface may appear green, white or black spots; peanut rice mold, peel off the red coat, the color become yellow. Many moldy foods can smell a musty odor. If you observe that the food has these traits of change, that is, you can initially determine that the food has mold contamination, should not continue to eat.
