Uses of Fractional & Food Distillation in Food Industry

Posted by USA Lab Equipment on Jan 6th 2021

Various forms of distillation are used in the food processing industry to separate and purify volatile food products from aqueous blends. A common type of distillation implemented for such applications is vacuum distillation. To learn more about the role of vacuum distillation in food processing, continue reading. 

What Is Vacuum Distillation?

Essentially, vacuum distillation is the process of separating a liquid compound based on differences in boiling points. It takes place under reduced pressure which decreases its boiling point and allows the process to take place at a lower temperature.

To understand the role of vacuum distillation in food processing, it is also important to first understand how vacuum distillation works.

During the process, the pressure in the column above the solvent is lowered so that it is less than the vapor pressure of the compound. As a result, a vacuum is created which causes the elements of the compound that have a lower vapor pressure to evaporate, leaving behind a purified distillate. This process is ideal for purifying compounds quickly and efficiently and is beneficial for compounds that are not readily distilled at ambient pressures.

The Use of Vacuum Distillation in Food Processing

Vacuum distillation is widely used in the food processing industry for numerous different applications. Generally, fractional distillation is used as an initial means to separate liquid components. However, creating the extremely pure components necessary in the food processing industry through the implementation of only fractional distillation is generally highly challenging or virtually impossible. As such, successive uses of fractional distillation such as vacuum distillation in food industry are often implemented to achieve a higher degree of purity. Some of the most common uses of vacuum distillation in the food processing industry include:

  • The creation of flavors
  • The production of alcoholic beverages from raw materials such as fruits or grains
  • Concentrating essential oils
  • Deodorizing fats and oils
