Consumers are becoming increasingly aware of their health and their impact on the environment, which is pushing them to adopt healthier and more sustainable diets. This has led to an increase in the demand for plant-based food products, such as food roots.

It is important to note that roots with low moisture content may lose some of their nutritional properties over time and should be stored properly to avoid mold and insect contamination.


What microbiological infections if the roots are not properly handled and stored?


If the roots are not properly handled and stored, they can become contaminated with various microbial pathogens, such as:


  • Bacteria: Certain bacteria such as Salmonella, Escherichia coli (E. coli) and Staphylococcus can survive on the root surface and cause infections.
  • Molds: The roots can be contaminated with molds such as Aspergillus flavus and Aspergillus niger , which can produce toxins that are harmful to health.
  • Yeasts: Some yeasts such as Candida can grow on the roots if stored in a moist environment and can cause infections.


If these pathogens are ingested, they can cause illnesses such as gastroenteritis, respiratory infections, skin infections, and other health issues. It is therefore important to take the necessary precautions to minimize the risk of infection by handling and storing the roots correctly.


Which industrial pasteurization treatment to treat contaminated roots while preserving its intrinsic qualities?


The industrial pasteurization treatment commonly used to treat contaminated roots while retaining their intrinsic qualities is known as steam pasteurization. This method consists of passing the roots to a high temperature, generally between 90°C and 115°C, for a fixed period, to kill pathogens while preserving the organoleptic properties of the roots.

The duration of pasteurization depends on the temperature and the susceptibility of the pathogens, it can last several minutes. Steam pasteurization is an effective way to minimize the risk of infection while preserving root quality.

It is important to note that pasteurization can affect root properties in different ways, such as changing colors, textures, and flavors. That’s why it’s important to work with a qualified supplier who uses the best pasteurization practices to ensure root quality and safety.
