Core Competencies
Retort Beverage Processing
A sterilization method where sealed containers of beverages, particularly low-acid products, are placed in a retort (pressure cooker-like machine) and heated under pressure with steam or hot water to temperatures of 245-255°F (118-124°C) to eliminate microorganisms and ensure product safety and shelf stability at ambient temperatures.
Formulation Development
Using our years of expertise in designing and optimizing formulations, we can provide quality-tested formulations as well as provide knowledge on how to enhance yours.
How It Works
Packaging
The beverage is filled into a hermetically sealed container, which could be a pouch, glass jar, or can.
Loading
The sealed containers are loaded into the retort, a large pressure vessel.
Heating
The retort is filled with steam and water, or a combination of steam and air, and the temperature is gradually raised to the required level (typically 245-255°F). Agitation may be used to improve heat transfer, especially for products that benefit from movement.
Sterilization
The high temperature inside the retort kills all harmful microorganisms, such as Clostridium botulinum spores, that could cause spoilage or illness.
Cooling
After the holding time at the sterilization temperature, the cooling process begins.
Overpressure is applied during this stage to prevent the pressure inside the containers from dropping, which could otherwise cause the containers to buckle or collapse.
Unloading
After the holding time at the sterilization temperature, the cooling process begins.
Overpressure is applied during this stage to prevent the pressure inside the containers from dropping, which could otherwise cause the containers to buckle or collapse.
Key Features & Benefits
Shelf Stability
Retort processing creates commercially sterile products that can be stored at room temperature for extended periods without refrigeration.
No Preservatives
The sterilization process itself prevents microbial growth, eliminating the need for chemical preservatives.
Versatile Containers
Retorts can be used for various packaging types, including flexible pouches, glass jars, and metal cans.
Product Quality
By preserving the product’s flavor, aroma, and nutritional value, it offers a convenient and high-quality option for consumers.
Safety
It addresses a critical food safety need by killing dangerous pathogens and spoilage microorganisms in low-acid beverages, which are at high risk for contamination.
