Recently, the Ministry of Health, Labor and Welfare of Japan updated the imported food information in violation of the Japanese Food Sanitation Law. In the information, a batch of peanut chocolate produced by Mars China detected aflatoxin exceeding the standard. On July 8, Mars China responded to the Beijing News reporter that the batch of products had been destroyed, was not circulated, and sold in the Japanese market.
What is aflatoxin? What’s the harm of aflatoxin to the human body? How to prevent it?
Aflatoxin can induce diseases such as liver cancer. Aflatoxin is a metabolite produced during the growth of Aspergillus flavus and Aspergillus parasiticus. There are many types of aflatoxins. It is more common in warm and humid environments and on the surface of moldy grains and organic matter. In 1993, aflatoxin was classified as a Class 1 carcinogen by the World Health Organization's Cancer Research Institute. It is a highly toxic and highly toxic substance, and 1 mg is a carcinogenic dose.
Zhao Jianjun, a chief physician of hepatobiliary surgery at the Cancer Hospital of Chinese Academy of Medical Sciences, told the media that the harm of aflatoxin is that it destructively affects human and animal’s liver tissue. Long-term intake of aflatoxin can cause chronic poisoning, lead to liver cirrhosis, and other diseases. In severe cases, it can lead to liver cancer and even death.
Besides, studies have shown that aflatoxin also increases the risk of gastric cancer, colon cancer, and kidney cancer.
Aflatoxin is widely found in daily life
Moldy peanuts, corn, sesame, nuts and other foods are most likely to breed aflatoxin because aflatoxin prefers a hot and humid environment.
At the same time, inferior sesame paste and self-pressing oil are also good places for aflatoxin to hide. To reduce costs, it is possible for bad merchants to use mildewed sesame seeds and peanuts as raw materials. The small oil mill has simple processing. It is impossible to refine raw materials and it is difficult to remove harmful substances. Therefore, they may cause aflatoxin in sesame sauce and oil.
Besides, the cutting board and chopsticks in the kitchen are also important places for the growth of aflatoxin. Since the cutting boards and chopsticks wear out during repeated use, these cracks are also a hidden place for aflatoxin. Therefore, kitchen utensils must be cleaned after use and must be renewed regularly.
Be sure to throw away the mold food.
Keep away from the harm of aflatoxin and focus on prevention. Since aflatoxin is a fat-soluble substance, it can only be cracked with a high temperature of 280 ° C or higher. This determines that aflatoxin in moldy foods cannot be effectively removed by washing or other general methods. Therefore, if the food is moldy, be sure to throw it away. Do not remove the mildewed part and eat the rest.
Zhao Jianjun introduced several tips to prevent aflatoxin. You need to soak a bubble and soften the food residue before washing chopsticks. After the edible oil such as peanut oil is poured into the pot, add a small amount of salt and stir 10 Up to 20 seconds. The neutralization and degradation of aflatoxin by the salt can eliminate the aflatoxin that may be present in most edible oils.
Besides, Aspergillus flavus is suitable for growth in a warm and humid environment. Therefore, to reduce the possibility of mildew growth, the ingredients in the home should be stored in a dry, cool environment as much as possible. When purchasing peanuts, nuts, and food, try to choose a small package and do not store it for a long time.
