There are hidden dangers in the popularity of "self-heating food".

The original title: "since-hot food" hot sales there are hidden dangers
At present, most areas of Guangzhou City restaurant food is still only restrictive opening, in order to avoid cross-infection, many enterprises have not yet opened the dining hall. Therefore, "self-heating food" has become a consumer hot spot in recent times. Consumer rights protection day is near, this reporter on the "self-heating food" market has been tested and investigated.
the acceleration of the pace of work and life, the vigorous development of the home economy, the rise of the lazy economy have contributed to the rapid explosion of hot food. Data from e-commerce platforms such as Taobao and Suning show that between January 20 and February 2, 2020, self-heating foods were among the top-selling products, with sales on many e-commerce platforms up more than 200% year-on-year. However, safety "small accidents" that come with hot food also occur from time to time. Reporters for self-heating food testing also showed that this popular food does have a lot of safety risks.
There-hot food has no national standard protection
China's food industry analyst Zhu Danpong believes that self-heating food is only one of the special nodes in the outbreak category, the application scenario is very limited, channels are limited to the development of self-heating food, with the normal distribution of takeaways and the full opening of future food, the demand for self-heating food or will return to normal levels. "The most critical thing is that self-heating foods are chemically hot, insecinable, and the industry lacks national standards."
survey data: consumers are most concerned about health and safety
Taobao data show that between January 20 and February 2, 2020, self-heating food ranked second among popular products, after snail powder products. Among them, sales of self-heating rice rose by 257.09 percent year-on-year. Suning Big Data also showed that sales in the hot pot category rose 370.27 percent year-on-year.
the other side of the hot market, consumer concerns can not be ignored. Recently, this newspaper launched an investigation on the use of self-heating food on the official microblogging and "food in Guangdong" WeChat Public.
"convenience" is the most important reason why consumers choose self-heating food. According to the survey data from Eat in Guangdong, 74% of consumers value this, 18% think it is "better than takeaway hygiene" and only 7% think it is "delicious". "Unhealthy" became a "label" in the minds of many consumers, with a whopping 71 percent of respondents saying it was "unhealthy" and 21 percent saying "don't care, eat well" and only 6 percent saying it was "healthy."
safety hazards are the biggest concern for consumers about self-heating foods, with 92 percent saying so. Among the many safety hazards, "plasticizer exceeding the standard" is the most concerned, with 34% concentrated here and another 28% concerned about "steam burns".
self-heating food does not need electricity or fire, water can be heated, the principle lies in coke powder, activated carbon and other components of the heating package heated by water. Consumers have to follow the guidelines strictly, so how many people are so cautious? As of yesterday's press release, a total of 1405 people on Weibo to participate in the survey, of which 626 people choose "very serious, on-the-go operation", 554 people choose "will simply look, almost good", 138 people choose "never look, operation has been in mind", 87 people choose "never look, according to their habits."
the self-heating pot test, try three
question one:
heating packet and water which put first?
your hand fast enough to be safe?
"I put the heat pack first and then added water, and it reacted quickly and the steam kept coming up. I hurriedly put the plastic rack of vegetables on the shelf, a tension, the shelf did not put good, part of the water inserted into the lower layer, lime water mixed into the food. My hand was still steamed. Ms. Wu recalls the first time she ate from a hot pot, "turning over the scene", since the hot dishes mixed into lime water, had to throw away the whole box.
In this regard, Guangzhou Daily all-media reporters tried to release the heat packet before pouring into the water, as well as first add water and then release the heat package, found that the former due to the water to produce a time difference, more prone to "early reaction, release of steam" phenomenon, hot hand higher chance. Reporters tested the bottom of the sea fishing, Mo Xiaoxian, canniable valley, open small stove, since hi pot, Hongdenlong 6 self-heating food, operating guidelines are not completely unified. In addition to bottom fishing, the remaining 5 operating methods are more "dangerous" "first heat package and then cold water", in which "Mo Xiaoxian" guidelines also remind: "hot package in the water 15 seconds to start heating." "If the heat pack is ready, the time to pour water, put the food rack and lid on is controlled to 15 seconds - it's a "hand-thring" race."
question two:
water is not clear, do you feel good enough?
water control is also difficult for some consumers: if too much water, boiling lime water easily spills into the upper dishes; Mr. Cai, who works for a cultural company, said that although the instructions say the water volume is up to 210 milliliters, but the family does not have a cup, he can only estimate the addition of water, the initial water added too much, directly overflowing the box, "frightened me to avoid the distance."
reporters saw that the bottom of the sea fishing, self-hi pot and open small stove in the box and food rack clearly marked "note water level", but since hi pot only in the plastic box outside the label, not marked in the box, "Hongdenlong" with two packages of water, direct control of the water. "Mo Xiaoxian" and "cannig eater valley" neither in the box to mark the water level, nor give the packaging water, "cannigated valley" did not even give a water warning, only said "to have not heated the package", all by the consumer feel. "Mo Xiaoxian" gives "210 ml of water" guidance.
question three:
in the confined space to eat self-heating pot has hidden dangers
reporters according to the guidelines to operate a "self-hi pot", 15 minutes later opened but found that the heating package has cracked. It has been observed that the reminders on each heat packet are also inconsistent and that "closed disablement" is not mentioned on some heat packets.
can be seen from the outer packaging instructions, the heating package contains more calcium oxide and aluminum powder, both of which will release flammable gas hydrogen in the event of water. Food engineer Zeng Qiuwen said that the heat package reaction will produce hydrogen, if hydrogen in the air volume concentration of between 4.0% to 75.6%, even if encountered a little static sparks will explode. In other words, if in a confined space, while more than one person is eating from the hot pot, there is a certain security risk. "So, be sure to pay attention to ventilation when eating, try not to eat in a small confined space. In addition, self-heating ingredients and risks should be noted. Zeng Qiuwen thought.
