Retort processing is a method of preserving food that involves heating it in a sealed container to a high temperature, typically between 240 and 250 degrees Fahrenheit (116-121°C) for a specified time, which depends on the size and type of container and the food being processed. This process kills any harmful bacteria or microorganisms that may be present in the food, allowing it to be stored safely at room temperature without refrigeration for an extended period of time.Retort processing is commonly used to preserve canned foods, such as vegetables, fruits, meats, and soups. The process involves placing the food in a container, sealing the container, and then heating it in a retort, which is a specialized pressure cooker. The heat and pressure help to kill any microorganisms in the food and ensure that it is safe to eat.Retort processing is a popular method of food preservation because it allows for convenient storage and transportation of food products without the need for refrigeration. However, it is important to follow proper processing procedures to ensure the safety and quality of the food. In addition, retort processing can affect the nutritional value and taste of some foods, so it may not be suitable for all types of products Types-Steam retorting: This is the most widely used retort process and involves heating the product with steam at high temperatures and pressures.Water immersion retorting: In this process, the containers are submerged in hot water instead of steam, and the water is heated to high temperatures and pressures.Hot water spray retorting: This process involves spraying hot water directly onto the containers, which are then heated to high temperatures and pressures.Microwave-assisted retorting: In this process, microwave energy is used to heat the food, which is then processed in a conventional retort.Aseptic retorting: This is a specialized process that involves sterilizing the product separately from the container, then filling the sterile product into a pre-sterilized container.Retort processing is a widely used method of food preservation and has a significant market share in the global food processing industry. The market for retort processing is driven by the increasing demand for convenient, shelf-stable food products that can be stored at room temperature for an extended period of time.The market for retort processing is segmented based on the type of food product, packaging material, and geography. Canned vegetables, fruits, and meat products are some of the most common food products that are processed using retort technology. The packaging materials used for retort processing include glass, metal, and plasticAccording to a study conducted by Transparency Market Research (TMR), retort packaging market is set to grow at a CAGR of 5% by 2027.
