Due to its high moisture and fresh meat content, wet pet food has always been a high-risk category for microbial growth. Traditional production methods often rely on high-temperature sterilization or the addition of large amounts of preservatives to achieve long-term storage at room temperature. The former destroys nutritional value and flavor, while the latter raises concerns among pet owners. Low-temperature baked wet pet food sterilization technology, with its unique advantages of non-thermal physical sterilization, builds a zero-additive food safety defense. It eliminates the need for high-temperature cooking and the addition of any chemical preservatives, completely killing all harmful microorganisms such as Salmonella, E. coli, and mold in wet food, while fully preserving the original state of the ingredients from the low-temperature baking process. This perfectly meets the core demand of pet owners for "clean ingredient lists" in pet food.

 

Technical details supporting end-to-end aseptic control

 

The implementation of this technology is supported by a complete end-to-end aseptic control system, laying a solid foundation for the final sterilization effect from the pre-processing stage of the ingredients. The low-temperature baking process is completed in a closed, sterile workshop. After the ingredients are cooked, they are rapidly cooled to room temperature to avoid secondary contamination during cooling. They are then vacuum-sealed in a Class 100 clean environment to ensure that no additional microorganisms are introduced into the sealed wet food. After entering the ultra-high pressure sterilization process, the uniform static pressure penetrates every corner of the packaging bag, completely inactivating even microorganisms hidden in the crevices of the meat pieces inside the wet food. This avoids the problem of "insufficient core temperature in large pieces of food leading to incomplete sterilization" that occurs in traditional high-temperature sterilization. The entire sterilization process involves no chemical intervention, does not alter the natural properties of the ingredients such as pH value and water activity, and leaves no harmful residues. The final wet food fully meets the highest safety standards for pet food.

 

Rebuilding the Quality Trust System of the Pet Wet Food Industry

 

The large-scale application of low-temperature baked pet wet food ultra-high pressure sterilization technology is gradually rebuilding consumer trust in the quality of domestically produced pet wet food. In the past, many pet owners worried about preservatives and incomplete sterilization in wet food, preferring to choose more expensive imported products. This new technology allows domestic pet food manufacturers to produce "all-fresh-meat, additive-free" wet food with an ingredient list consisting only of fresh meat, fruits, vegetables, and micronutrient supplements. The safety and nutritional value of these products have reached internationally leading levels. Furthermore, the ultra-high pressure sterilized wet food can be stably stored at room temperature for 12-24 months without the need for cold chain transportation and warehousing, significantly reducing distribution costs. This allows more ordinary pet owners to purchase high-quality, additive-free wet pet food at affordable prices, ensuring that every pet can enjoy safe and fresh, all-natural fresh meat wet food.
