Retort packaging is an advanced food sterilization method that involves heating food and its packaging to high temperatures inside a pressure vessel, or retort. This process typically reaches 240–250°F (115–121°C), effectively sterilizing the contents and creating a shelf-stable product that can be stored at room temperature for one to two years. The technique is designed to preserve food quality while ensuring safety and extending shelf life.
