DTS Sterilization Retort

Pet Food

Pet food is feed specially developed for pets and contains all the nutrients needed for pet growth, such as protein, fat, vitamins and minerals.

Sterilization Characteristics of Pet Food

1. Sterilization method:

Thermal (high temperature) sterilization is the process of heating sealed cans to a specific temperature and maintaining it for a certain period of time. This process can effectively kill harmful microorganisms such as bacteria, mold and pathogens, ensuring that the product is safe for consumption. Sterilization method and timing depend on product type, packaging and size.

2. Product flavor:

The sterilization process plays a key role in shaping the flavor. It may enhance the flavor through the Maillard reaction or cause odors. Various parameters during the sterilization process, including time, temperature and sterilization value (F0), all have a significant impact on the taste of the meat in the sauce. In order to ensure the palatability of the food, this link is crucial because it is directly related to the formation of the taste that pets like. The formation of these flavors is closely related to the consumption of Maillard reaction precursors, such as amino acids and reducing sugars.

3. Heat distribution:

The core of the sterilization process is to achieve an even distribution of heat inside the can, which is decisive for eliminating potential bacterial cold spots. Ensuring that each part reaches the temperature required for sterilization is critical to maintaining the safety and quality of canned foods.

4. Nutrients:

While high temperature sterilization effectively kills harmful microorganisms, it is also designed to preserve the nutritional content of pet food. Manufacturers carefully balance the sterilization process to preserve essential vitamins, minerals and proteins.

5. Shelf life:

Wet food pet food that has been processed through a strict sterilization process can remain safe for long periods of time without refrigeration. Its unique sealed can design effectively isolates external contamination, provides a stable shelf life for the product, and ensures that pets can enjoy fresh and healthy food.

Sterilization Precautions for Pet Food

Sterilization temperature

The core of high-temperature sterilization is precise temperature control. Too high a temperature will damage the nutritional content of food, while too low a temperature cannot completely eliminate potentially harmful microorganisms. In order to ensure the safety and nutritional value of wet food, the optimal sterilization temperature must be set according to the composition and packaging materials of wet food. At the same time, the length of sterilization time is also key. If the time is too short, the microorganisms will not be completely eliminated; if the time is too long, the taste and nutritional value of the food may be affected. Therefore, when setting the sterilization time, it is necessary to comprehensively consider the characteristics of the wet food and the selected sterilization temperature to ensure food safety while minimizing the loss of food quality.

Packaging materials

Packaging materials play a vital role in maintaining the quality of pet wet food and extending its shelf life. We need to carefully select packaging materials that can withstand high temperature processing and have good sealing and barrier properties to ensure that the quality of wet food is not compromised during the sterilization process and to avoid the risk of contamination and oxidation. At the same time, when selecting packaging materials, we must also fully consider their impact on the taste and nutritional value of food to ensure the best quality assurance for pets.

Equipment maintenance

To ensure the safety and quality of pet wet food, the normal operation of sterilization equipment is crucial. Sterilization equipment needs to be maintained and inspected regularly to ensure it is in good condition. These emergency measures ensure the continuous and effective operation of sterilization equipment and provide guarantee for the safety and quality of pet wet food.

High Temperature Sterilization Characteristics of Cat Food

★ Sterilization method:
High temperature sterilization retort technology is a sterilization method that takes into account both safety and quality. It first packs cat food and places it in a sterilization tray, and then pushes the sterilization tray into the sterilization retort. Then, by raising the temperature to a high temperature state and maintaining it for a certain period of time, microorganisms such as bacteria, mold, and yeast in the product are effectively eliminated. Compared with traditional canning processes, high-temperature sterilization retorts can better maintain the vitamins, flavor and texture of cat food wh ile maintaining the same level of sterilization. This technology not only ensures the safety of cat food, but also retains its nutritional value and original taste as much as possible.
★ Raw material quality:
In the production process of cat food, the screening and inspection of raw materials are crucial links to ensure that they are free of impurities and pollution. At the same time, we attach great importance to quality control, during the production process and ensure that each batch of cat food meets high-standard quality requirements through multiple sampling tests to provide safe and reliable products for our pets.
★ Quality assurance:
Compared with other sterilization methods, the unique feature of the sterilization retort is that it can minimize the loss of products and changes in sensory attributes during the sterilization process. By using a retort, we ensure that the vitamins, flavor and texture of our products are fully preserved. For cat food, this means that our products not only retain their delicious taste, but also maintain their rich nutritional value. These properties are crucial for your pet as they directly impact their health and well-being.
★ Stable shelf life:
The stability of pet cat food treated with high-temperature sterilization technology is significantly enhanced. The processing method improves the stability of cat food during storage and transportation, extending the shelf life. This provides consumers with a reliable and long-lasting product experience that meets their demand for high-quality pet food.

Sterilization Precautions for Cat Food

Sterilization temperature

Precise control of temperature and time is crucial in the sterilization process. Finding a balance between killing bacteria and maintaining food quality is important, considering factors like nutrition, taste, product characteristics, packaging requirements, and storage conditions. Sterilization methods such as high-temperature/high-pressure, low-temperature/long-term, and freezing are considered based on these factors.

Packaging sealability

The sealing of cat food packaging has a crucial impact on the sterilization effect and the shelf life of the food. If the packaging is not well sealed, it will lead to the invasion of bacteria and other microorganisms, causing the food to spoil. Therefore, the packaging needs to be inspected before sterilization to ensure that its sealing performance is good.

Monitor the sterilization process

During the sterilization process, parameters such as temperature and pressure need to be continuously monitored to ensure the stability and consistency of the sterilization process. At the same time, it is also necessary to conduct quality inspections on the sterilized products, such as appearance, smell, taste, etc., to ensure that they meet hygienic standards and quality requirements.

The key to the quality and safety of pet cat food lies in the sterilization of cat food. Choose appropriate sterilization methods and equipment to ensure the safety and taste of the product. Proper sterilization and nutritional supply are crucial to the health of cats, and the high-temperature sterilization process not only reflects the manufacturer's emphasis on food safety, but also highlights its pursuit of excellence in product quality. This rigorous craftsmanship ensures that every bag of cat food meets consumer expectations and provides pets with healthy, nutritious food options.
