Extending The Shelf Life of Your Chilled Ready-Meals
The shelf life of ready meals is crucial for both food producers and retailers. Consumers demand fresh, nutritious meals with convenient storage options, while food producers look for ways to extend product longevity without sacrificing taste or adding preservatives.
Micvac has perfected this balance, offering a unique solution that ensures over 45 days of shelf life while preserving food’s natural taste, texture, and color.
Comparing shelf life technologies
As illustrated above, when it comes to extending the shelf life of ready meals, two main technologies are commonly used: Cook & Chill and Retort. However, both approaches present limitations:
Cook & Chill
This method focuses on retaining the taste, texture, and color of meals but typically only offers a shelf life of around 7 to 10 days. The reason? Food is cooked and then chilled, which slows down spoilage, but without substantial protection, products still degrade rapidly.
Retort
In contrast, retort technology offers a long shelf life of up to several months, but at a significant cost. High-temperature processing required for retort can damage the taste, texture, and nutritional quality of food. Meals often taste overcooked and lose the appeal of freshly made dishes.
The challenge for food producers has always been to achieve both: retaining the taste, texture, and color of meals while also ensuring long shelf life – something neither Cook & Chill nor Retort can achieve on their own.
How Micvac achieves the perfect balance
An integrated system of microwave technology + packaging components
Micvac’s technology is built to provide a comprehensive solution that enhances shelf life while preserving the quality and integrity of your product.
The key lies in the seamless integration of our Microwave Tunnel with packaging components like the Micvac FlexTray®, Sealing Film, and Micvac FlexValve®, working together to offer a robust, efficient process that keeps meals fresh for over 45 days.
When sealed trays filled with fresh or raw ingredients pass through the Micvac Microwave Tunnel, they are cooked and pasteurized for seven minutes. The latter has been shown to allow food to reach 98°C for two minutes, which is crucial for controlling food safety risks, particularly Clostridium Botulinum, without compromising the meal’s texture or nutritional content. This rapid heat treatment ensures meals stay fresh, flavorful, and nutritious.
The role of Micvac FlexTray®
The Micvac FlexTray® plays a big role in our process. It is specifically designed to withstand the rapid yet gentle pasteurization that happens inside the tunnel. But it’s more than just durable – it actively enhances the cooling process. After pasteurization, the tray becomes subtly concave, allowing for faster and more uniform cooling. This helps speed up production and extends shelf life by reducing the amount of time the product stays in the temperature danger zone, further safeguarding the food.
Sealing in freshness with innovation
Micvac’s Sealing film turns each package into a mini pressure cooker during the cooking phase. This locks in both flavors and nutrients, ensuring that the meal inside remains fresh and appetizing. After heating, the Micvac FlexValve® is applied, and with a quick blast of cool air, the pressure inside the package shifts, creating a vacuum seal. This vacuum is the secret behind our ability to maintain freshness and nutritional quality for over 45 days, without relying on artificial preservatives.
The Micvac Advantage
Choosing Micvac means choosing a solution that’s been meticulously designed to optimize ready-meal production. Our system offers the longest shelf life on the market without the downsides of overprocessing or nutrient loss often seen with retorting or standard cook-and-chill methods.
With Micvac, meals retain their color, texture, taste, and nutritional value from day one to day 45, offering your customers the freshest, most appealing products possible.
