Microbiology

Microbiological analyzes are performed in food in order to control microorganisms contamination in the production processes from the acquisition of raw materials, its use and manipulation during manufacture, the manipulators, utensils and environment hygiene, until the finished product.

It may also be used:

 

  • In processes of commercial sterility control
  • Calculation of shelf life of food
  • In cases of Customer Service for suspected contamination by microorganisms
  • Monitoring the production process
