Not long ago, the Forum on Innovation and Health Peak of Chinese Canning Industry, sponsored by the Chinese Food Science and Technology Association and the Chinese Canning Industry Association, was held in Xinchang, Zhejiang Province. Experts and scholars from the food science and nutrition community attended the forum to take stock of and resolve canned food rumors over the years.

 

Rumor 1: canned foreigners in China don't eat.

It is rumored that foreigners do not eat cans made in China. Is it true that the moon of a foreign country is more round than ours? In fact, canned food in China has already been exported to the United States, South Korea, Japan, Europe and so on. The United States has also incorporated Chinese canned food into the nutritional meals of divers and students.

 

"The total output of canned food in the world is nearly 50 million tons annually, with more than 2,500 varieties. At present, China has become the largest canned food producer and exporter in the world. Among them, canned asparagus and canned oranges account for 70% and 80% of the world's Canned exports.

 

Myth two: canned preservatives

Meng Suhe, chairman of the Chinese Food Science and Technology Association, said that 892 canned food enterprises with a total revenue of 175.387 billion yuan in 2017, an increase of 5.46 percent over the same period of the same year. However, compared with the development speed and quality of the national food industry, China's canned food industry is still at a low level. Rumors are one of the reasons that restrict the development of the canning industry, especially the spread of rumors such as "cans contain preservatives, packaging materials are harmful to health".

 

In this regard, President Charles said that the principle of canned food preservation is to rely on sealed sterilization to achieve commercial aseptic requirements, do not need or allow the addition of any preservatives. Canned food packaging materials, in addition to tin cans, glass cans, aluminum alloy cans, aluminum-plastic composite packaging materials, high barrier plastic materials and paper packaging materials Lile. Canned food is safe, hygienic and convenient. It can be stored and circulated at room temperature for a long time. It can regulate the season of agricultural and sideline products and the supply between dispensing areas. It can better preserve the sensory quality and nutritional value of natural fresh food.

 

In fact, as early as the birth of New China in the early years, canned food has assumed the role of the "big brother" in the food industry. Mr. Zhang Xueyuan, a food scientist, said in his lifetime that during the period of resisting the United States and aiding the DPRK, soldiers in front of them urgently needed canned food supplies, and that "producing the best canned food for a lovely life" was the belief of the food people of that generation. In a short time, they produced more than 10 kinds of vegetables, fruits and canned meat, which were continuously sent to the volunteers. After the war, in view of the market demand, the food man also developed a "red-cooked elbow" and "orange chicken" and other flavor cans. Among all the export products at that time, the amount of foreign exchange earned by canned goods ranked first, which was worthy of the title of "Big Brother".

 

Myth three: canned food is unhealthy.

 

Nowadays, some people are doubtful or even negative about the nutrition of canned food, and there are many clinical nutritionists who do not know much about food science. This led to the standard "no use of canned food" in some nutritious meal standards. For a long time, canned elder brother has suffered a lot of injustice.

 

Ding Gangqiang, director of the Institute of Nutrition and Health, China's Centers for Disease Control, explained that cardiovascular diseases had become the leading cause of death in the 1990-2015 mortality survey of major diseases among Chinese residents, with rural areas accounting for a higher proportion than urban areas. Irrational dietary structure has become the main inducement. The intake of red meat and fine grains is on the high side, and the intake of coarse grains, seafood, fruits and vegetables is on the low side. Director Ding said: "The use of aquatic products, vegetables, canned fruit can make up for these nutritional deficiencies. Canned fruit is a good nutrition if a patient with a fever for a few days can't eat. There is also a good choice for people traveling and travelling to bring some meat and canned fruits.
