What is Retort Technology?

Retort technology refers to the technology used in the thermal processing of food and food products. It is a rather unique method and is vastly different from simple packaging as the packages are packed using metal, some alloys or some flexible laminating materials. All of this is basically done to prevent the food from going bad due to a number of reasons, some of which are microbiological in nature. In this technology the food is generally processed and packed together.

There are two main ways in which this technology is used, one is through the use of steam and other is by using superheated water, which enables the cooking of food in individual packages itself. With the advancement in food technology, new innovations in the food industry are seen every day and since the application of retort processing in food technology, the hygiene levels of food packaging have immensely improved.

Steps involved in Retort Processing :

There are seven steps involved in the processing and packaging of food using retort technology,

  • Preparation of Retorts: this first step requires the thorough cleaning and washing of the machinery that is to be used, like – thermometer, valves, gauges, etc.
  • Loading: the second step is loading the packaging material, like – cans or retort pouches.
  • Venting: Then venting takes place, this is the process which ensures that there is no pre-existing air in the packaging containers.
  • Cool off Time: Subsequently, the retorts are given time to rise up to the temperature needed for processing.
  • Processing: during this step it is ensured that no fluctuation in temperature happens throughout the process.
  • Blowing down: Then the supply of steam is stopped, giving the product time to cool off.
  • Unloading: finally, the retorts are packed and ready to be transported.
