The hottest green food don't let harmful packaging

Green food don't let harmful packaging mix water

most green food packaging is not "green"

there are more and more kinds of green food. From milk, vegetables to fruits, grains, etc., green food has gradually entered people's daily life. However, the outer packaging of many green foods on the market is not environmentally friendly

recently, it was found in some supermarkets in Beijing that although the surface of some pollution-free vegetables and green vegetables were packed with degradable fresh-keeping film, the trays were PVC plastic products. Some of the cut and peeled fruit platters of this exhibition will gather in Changzhou, Jiangsu Province, including the world's top spinel graphene team and more than 10 key enterprises; There are also some fruits labeled as green food, whose surface is wrapped with disposable foaming plastic protection; High quality rice with A-level green food label still uses plastic woven bags as packaging bags. When asking customers whether they care about these outer packaging, some salespeople said that the things in the supermarket are clean and hygienic with quality assurance, and consumers have been used to this kind of packaging, and no one has questioned the packaging

in this regard, Che Xiangfu, Deputy Secretary General of China Packaging Industry Technology Association, said that due to the immature conditions in all aspects, there are no unified requirements for the product packaging of green food production enterprises. In real life, most green foods do not use environmental protection packaging materials to realize the real high-end and technicalization of relevant industries, and some green foods even use some harmful substances as packaging. For example, many green foods such as grains and vegetables are packed with plastic bags and plastic trays. The material PVC is not only toxic to human body, but also easy to pollute the environment after use. Many enterprises, businesses and consumers only pay great attention to whether the food itself is "green", but ignore the safety and environmental protection functions of packaging

green food packaging requires that food packaging have a long shelf life, do not bring secondary pollution, less loss of original nutrition and flavor, low packaging cost, convenient and safe storage and transportation, increase beauty, cause appetite, etc. the whole process of raw materials, product manufacturing, use, recycling and waste should be conducive to food safety and environmental protection. Li Xingmin, associate professor of School of food science and Nutritional Engineering, China Agricultural University, said in an interview

it is understood that China's relevant green packaging standards have not been promulgated and implemented. In this case, in order to make "green food" truly "green", manufacturers should try to use recycled environmental protection packaging, such as paper packaging, degradable plastic packaging and biological material packaging. As consumers, they should also pay attention to identifying whether the packaging of green food on the market is environmentally friendly, so as to avoid buying discounted "green food" at a higher price

harmful packaging is harmful to human health

according to experts from the school of food science and Nutritional Engineering, China Agricultural University, at present, there are still improper phenomena in the production, processing and use of food packaging materials in China, such as the extensive use of whitening paper for food packaging in the food industry, including green food. In order to improve the whiteness of paper in the production process, most of them are treated with fluorescent brighteners. Fluorescent brighteners have great toxic effects on humans and animals

in addition, the ink pollution of food packaging paper is also very serious. At present, many enterprises like to use color packaging paper. If color ink comes into direct contact with food, it will cause safety problems. There are also many high-grade food packaging using tin foil. In fact, the lead content in 60% of tin foil exceeds the standard, and "lead is recognized as the" culprit "of acute and chronic heavy metal poisoning. In addition, many foods are packed in plastic bags, such as grains and vegetables. In order to improve the performance of some plastics, manufacturers have added plasticizers and antioxidants, which are often toxic. Polyvinyl chloride is also a kind of commonly used plastic. Additives are used in its production. For example, dibutyl phthalate is used as plasticizer. Packaging food with these things will lead to chronic lead poisoning

in the interview, experts said that whether ordinary food or green food, if environmental protection packaging is not used, it will be neither conducive to fresh-keeping, nor hygienic, but also cause unpredictable consequences. Therefore, people must attach great importance to green packaging. Protecting the quality of green food and maintaining the freshness of green food are the basic functions of green packaging

at present, green aseptic fresh-keeping packaging is commonly used in countries with more developed packaging technology in the world, which is the preferred target of green food packaging and can be applied to packaging fruit juice, milk, mineral water, etc. 1/3 of beverages in Britain, Germany, France and other countries have used such packaging; The second is the fresh-keeping packaging bag, which is used to pack green food such as fruits and vegetables. At a certain temperature, it can be kept fresh for 60-80 days, and the fresh-keeping packaging bag can be reused for recycling; Third, paper packaging, which has been widely promoted in green food packaging, can directly package quantitative grain, which is favored by users; The fourth is degradable plastic packaging bags and trays, "Ma Zhanfeng said. It is also an ideal green food packaging, which can completely replace disposable foaming plastic trays (boxes), solve white pollution and protect the ecological environment; Fifth, edible packaging is a good way to solve the contradiction between food packaging waste and environmental protection. It is a kind of packaging film that does not affect the flavor of green food

although there is still a certain gap between China's current packaging industry and developed countries in terms of technical level and talent allocation, trying to adopt green packaging has become a fashion for food packaging and a trend of packaging development
