Interpretation of "Aseptic Cold Filling" - Difference between Cold and Hot

Although PET aseptic cold filling has not been developed for a long time, several well-known beverage equipment manufacturers in the world already have a relatively mature aseptic cold filling process. At present, aseptic cold filling has become one of the hottest topics in the domestic beverage market!

Strictly speaking, what is the meaning of aseptic cold filling technology for beverages? Compared to hot filling, what are the differences in technical aseptic cold filling? What are the advantages?

Strictly speaking, aseptic cold filling technology for beverages refers to an advanced filling technology in which drinks do not add any preservatives and are filled at room temperature, and no post-sequence (sterilization) treatment is required to meet the product's shelf life requirements. . Its low packaging cost and the diversity of package appearance make this technology an international trend for the development of juice and soft drink packaging equipment. At present, the “cold filling” and “hot filling” disputes in the domestic beverage market are mainly directed at the packaging of fruit juice beverages and tea beverages in PET bottles. The following table shows some comparisons between PET bottle hot filling technology and aseptic cold filling technology.

Comparison of PET Bottle Hot Filling and Aseptic Cold Filling Technology

Through the above comparison, it is not difficult to see that the high investment and operational risk of aseptic cold filling equipment determine that this technology cannot replace hot filling technology, hot filling and aseptic cold filling in two short filling times. It will coexist and develop together for a long time.
