Popcorn+Coke "is the standard for watching movies. However, in recent years, food safety incidents have occurred frequently, and many consumers are worried that popcorn will also have problems. In 20 14, Kunming Consumers Association issued a warning and took stock of 10 junk food, including popcorn. According to the warning information, long-term consumption of foods with high lead content such as popcorn will make people mentally retarded, children stunted and malnourished.

1 3, CCTV Finance's "Is it true" column detected heavy metals in popcorn, and it was found that four of the six popcorn samples contained lead, but the content did not exceed the national standard. Ouyang Chongxue, an associate professor in the Department of Food Science and Engineering of Nanchang University and director of the Food Engineering Experimental Center, told The Paper that long-term consumption of lead-containing food would accumulate in the body and cause damage to internal organs.

According to CCTV's investigation, the test results showed that the highest lead content in four samples of popcorn was 0.042 mg/kg, while the lowest lead content was 0.0 18 mg/kg. After searching in The Paper, it was found that the lead content in puffed food should not exceed 0.5 mg/kg according to the national food safety standard "Limits of Pollutants in Food" (GB2760-20 12).

From the processing technology, the new popcorn should not contain lead, so where does the lead in popcorn come from? Although the lead content does not exceed the standard, will it cause harm to the human body? Sun Shuxia, president of china health care association Food Nutrition and Safety Professional Committee, told CCTV reporters that from the processing method, popcorn in cinemas should not have a source of lead, and the lead content in the determination results may be due to the lead element attached to (corn) during transportation and drying.
