Aseptic filling is the ideal filling technique at present. After ultra-high temperature instantaneous sterilization (UHT), microorganisms in the air, such as bacteria, molds and yeasts, can be prevented from entering the packaging and chemical reactions can be avoided, so as to keep the original flavor of food. It has been proved that daily food has a short storage period and needs to be eaten in a short time. In the stage of food analysis, the service life of high acid food, acid food and low acid food can be prolonged after aseptic filling. Therefore, aseptic filling has a wide application prospect.
Low costs
Aseptic filling uses filling at room temperature, which can save more energy consumption compared with other hot filling. And it has lower requirements for the wall thickness of PET bottles, thus reducing the weight of bottles and costs.
A guarantee of the health of consumers
In recent years, the incidence of food safety incidents is high, and aseptic filling can play an important role in strengthening the hygiene and safety of food. The filling and packaging of products are carried out in the sterile environment, which greatly reduces the probability of infection.
