As the saying goes, people eat food for the day, food for safety first, the quality and safety of food is related to everyone's rest. From the perspective of food packaging, transportation, if the company can not guarantee the integrity of the product seal or cover, packaged food It may be polluted and deteriorated. In the process of cold chain transportation, the temperature of the refrigeration equipment cannot be controlled or the sterilization of special products will not be in place, which will have a certain impact on the quality and safety of the product.
How to protect the quality and safety of equipment from the perspective of food packaging and transportation technology
Food packaging: vacuum, nano-packaging anti-deformation sealing tester to ensure integrity
Whether food packaging is compliant will not only affect the appearance of the product, but also have certain food safety risks. If the packaging does not meet the specifications, the label will be easy to fall off, the words will not be cleaned, the smear will be modified, and the seal will not be sealed. Qualified, short shelf life, will also accelerate food deterioration, affecting consumer safety.
When entering the supermarket, it is not difficult to find that many foods and beverages are vacuum-packed, which can effectively isolate the air and prevent the food from being infected by microorganisms and affect the quality and safety of the product. The author understands that the vacuum packaging machine mainly extracts the air inside the packaging bag. , then filled with nitrogen or other mixed gas to make it resistant to oxidation, so as to achieve long-term preservation.
In addition, nanotechnology emerging in the market can also be used for food packaging, which can extend the shelf life of products and reduce waste of resources. Industry insiders point out that microbial contamination usually starts from the surface of food, and many foods and beverages do not have any resistance to microorganisms. Force', antibacterial packaging is the 'final defense', and nano-packaging technology has a good antibacterial effect, which can greatly reduce the risk of microbial contamination. It is understood that domestic enterprises have established a nanomaterial cooperation laboratory, which is packaging Industry nanotechnology research provides a strong guarantee, and will also promote nanotechnology to create new economic growth points in the packaging industry.
Of course, whether it is food vacuum packaging, or the development and application of nano-packaging technology in the future, the sealing inspection process is indispensable in the industrial processing process. Checking the integrity of the product is an important part of ensuring the safety of the food factory. If the product is vacuum-packed Displacement in the seal, or the granule product is sandwiched under the seal (or film), which may cause air leakage, which may lead to food deterioration or bacterial contamination. I understand that a food seal tester introduced by a company in Shanghai adopts ATC Micro The patented flow technology enables more sensitive detection, more stable performance, higher accuracy, and no interference due to gas volume changes.
Cold chain transportation: EPP incubator achieves constant temperature control Pasteurization technology extends shelf life
With the continuous upgrading of the consumer market, the rapid rise of fresh electricity and electricity, and the active encouragement of the state, China's cold chain logistics industry has entered a period of rapid development. However, compared with foreign countries, there are some 'pain points' in China's cold chain logistics, such as fake refrigeration. The car 'horizontal', the cost of cold chain is high, and the temperature control in the cold chain transportation is improperly controlled, which makes the product deteriorate. The seafood products are difficult to transport, the shelf life is short, and it is susceptible to pollution and affects the safety of seafood products.
In view of the temperature control in cold chain transportation, the author was informed that a packaging material company in Suzhou has launched a 'one-piece antibacterial mirror EPP incubator', which has excellent thermostat, which solves the problem of unsatisfactory refrigeration and temperature in the turnover equipment. Or there is moisture infiltration and food contamination, deterioration problems. More importantly, the box uses antibacterial raw materials, which can effectively inhibit the growth of bacteria, ensuring the safety of fresh transportation.
Compared with other fresh products, summer seafood is very easy to deteriorate. Even in cold and cold conditions, it can't completely destroy all the germs. It is understood that in the beer festival in Qingdao, in order to ensure the quality and safety of seafood snacks, With the help of relevant experts, using pasteurization technology, seafood snacks can be preserved for two months under refrigerated conditions. Currently, this technology has been patented in China.
It can be seen that both food packaging and transportation can use technology and equipment to protect people's safety on the tip of the food. On the one hand, through vacuum packaging, the application of nano-packaging technology makes the product block the air and avoid microbial contamination. On the other hand, the use of the new EPP incubator and sterilization technology can ensure the safety of the products in transit.
