The Application of Sterilization Used in Foods and Drinks

Sterilization refers to any process that removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. After sterilization, an object is referred to as being sterile or aseptic.

How sterilization is used in foods and drinks

One of the first steps toward modernized sterilization was made by Nicolas Appert who discovered that thorough application of heat over a suitable period slowed the decay of foods and various liquids, preserving them for safe consumption for a longer time than was typical. Canning of foods is an extension of the same principle and has helped to reduce food borne illness ("food poisoning"). Other methods of sterilizing foods include food irradiation and high pressure. 

One process by which food is sterilized is heat treatment. Heat treatment ceases bacterial and enzyme activity which then leads to decreasing the chances of low quality foods while maintaining the life of non-perishable foods.

One specific type of heat treatment used is UHT (Ultra-High Temperature) sterilization. This type of heat treatment focuses on sterilization over 100 degrees Celsius. Two types of UHT sterilization are moist and dry heat sterilization. During moist heat sterilization, the temperatures that are used vary from 110 to 130 degrees Celsius. Moist heat sterilization takes between 20 and 40 minutes, the time being shorter the higher the temperature.

The use of dry heat sterilization uses longer times of susceptibility that may last up to 2 hours and that use much higher temperatures compared to moist heat sterilization. These temperatures may range from 160 to 180 degrees Celsius.
