Retort Types Difference


Retort processing is a method of sterilizing packaged food products to ensure safety and extend shelf life. There are several types of retort processes, each with its own characteristics and applications. 

Water Boiling Process:


The water boiling process, also known as boiling water immersion, is a relatively simple and less aggressive method of food sterilization. In this process, food products are placed in a container, usually heat-resistant plastic pouches, glass jars or cans, and completely immersed in boiling water for a specific period. The temperature typically reaches 100 degrees Celsius (212 degrees Fahrenheit), which is the boiling point of water at sea level.Besides, water boiling does not involve pressurization.

 

Medium Temperature Retort:


Medium temperature retort processing involves subjecting packaged food to a moderate level of heat and pressure for sterilization. The temperature in medium temperature retort processing ranges from approximately 100 to 121 degrees Celsius (212 to 250 degrees Fahrenheit). The pressure is typically lower than in high temperature retort processing.

 

High Temperature Retort:


High temperature retort processing is a more intense method of food sterilization. It involves subjecting packaged food to higher temperatures and pressures compared to water boiling or medium temperature retort processing. The temperature in high temperature retort processing can range from 121 to 135 degrees Celsius (250 to 275 degrees Fahrenheit), and the pressure is significantly higher.




The FAQs about Retort Pouch


What is a retort pouch?


A retort pouch is a flexible packaging structure made from multiple layers of materials designed to withstand the high temperatures and pressures in the retort sterilization process. It is used for packaging ready-to-eat or heat-treated food products.

How does a retort pouch work?


The retort pouch works by providing a barrier against moisture, oxygen, and light, ensuring the preservation and extended shelf life of the packaged food. During the retort process, the pouch is sealed and then subjected to heat treatment, effectively sterilizing the food inside.


What are the advantages of using retort pouches?


Retort pouches offer several advantages, including lightweight and space efficiency, improved product quality, convenience, enhanced shelf appeal, and versatility in applications. They are also more environmentally friendly compared to traditional rigid packaging options like cans or glass jars.


What types of food can be packaged in a retort pouch?


Retort pouches are suitable for a wide range of food products, including ready-to-eat meals, soups, sauces, wet pet food, baby food, seafood, and more. They are especially popular for products that require high-temperature processing and long shelf life.

How are retort pouches sealed?


Retort pouches are typically sealed using heat-sealing techniques, such as impulse sealing or hot-bar sealing. These methods create a strong and hermetic seal to ensure the integrity of the pouch during the retort process.


Are retort pouches recyclable?


The recyclability of retort pouches depends on the specific mono recyclable plastic materials used in their construction. While some pouches may be recyclable, many include multiple layers of different materials, making them more challenging to recycle. However, advancements are being made to develop more sustainable and recyclable retort pouches.

Can retort pouches be microwaved?


Our retort pouches can be specifically customized to be microwavable, allowing consumers to conveniently heat the food directly in the pouch. However, it is important to check the packaging instructions to ensure the specific pouch is safe for microwave use.

Material structure: AlOx coated PET/NY/ RCPP
Usage: Cooked rice, curry sauce, soup, meat stew, pet meal 
& other ready-to-eat foods

The microwavable retort pouches are safe in a microwave oven without the risk of electric sparks. Unlike traditional retort pouches that utilize an aluminum layer, the microwavable version features a polyester film coated with Alumina (AlOx). This Alumina-coated polyester film provides a barrier property that is comparable to that of an aluminum layer. The retort bags offer the convenience of easy reheating, making it a practical choice for consumers seeking a quick and hassle-free meal preparation option.


Are retort pouches more expensive than other packaging options?


The cost of retort pouches can vary depending on factors such as size, materials used, and customization requirements. While they may have a higher upfront cost compared to some traditional packaging options, the benefits they offer, such as extended shelf life and reduced transportation costs, can make them a cost-effective choice in the long run.
