Soft package,autoclave retort machine for food sterilization-DTS

In Soft Package

For flexible packaging vacuum products, the best sterilization mode is Water Immersion Retort

When using flexible packaging materials to package products, we have to consider the following factors：

1. Material compatibility:

The selection of flexible packaging materials that are resistant to heat sterilization is critical. These materials must be able to remain stable at high temperatures without degrading or releasing harmful substances. For example, multi-layer heat-resistant pouches made of plastic and metal foil are a good choice to withstand the rigors of the sterilization process while effectively shielding against contaminants.

2. Seal integrity:

The seal of the package must be strong to prevent breakage during the sterilization process. Poor seals can lead to contamination, which can affect the sterilization results.

3. Product sensitivity:

Different food products have different sensitivities to high temperatures. Therefore, recipe parameters (e.g., time and temperature) should be carefully calibrated to the specific product to avoid over-processing, which could affect the taste, texture and nutritional value of the product.

4. Pressure and heat distribution:

Achieving uniform pressure and heat distribution within the sterilization retort is critical for effective sterilization. Uneven distribution can lead to cold spots, which allow microorganisms to survive in these areas. Therefore, proper loading techniques and sterilizing retort design are important to ensure uniform sterilization of all packages.

Food packaged in flexible Packaging Materials

With regard to data on product sensitivity during retorting of foodstuffs packaged in flexible packaging materials, the following are some specific examples.

Meat Products

For example, soft-packaged ham or meat products may require high temperature treatment at 121°C for at least 10 minutes to ensure sterilization while avoiding overheating that could lead to degradation of food quality

Fruit and Vegetable Purees

Flexible packaged fruit and vegetable purees, such as apple puree or tomato sauce, may need to be sterilized at slightly lower temperatures, e.g., 85-95°C, to maintain the flavor and nutrient content of the food.

Dairy Products

Soft-packaged yogurt or cheese may require special attention to temperature control during autoclaving to prevent denaturation of proteins, and are usually processed at temperatures between 90°C and 95°C for 5-10 minutes.

Beverages

Flexible packaging of fruit juice or tea drinks in the high temperature sterilization needs to maintain its original flavor and nutritional value, usually between 85-95 ℃ processing 5-10 minutes.

These parameters can be adjusted according to the specific food type and the temperature resistance of the packaging material. It is important to ensure that the sterilization process is effective in killing microorganisms while maintaining the original quality of the food as much as possible.
