Abstract
A method and device for monitoring and controlling a pharmaceutical, chemical or food process, in which the biological activity and/or the bio-mass of micro-organisms in the process is monitored, and in which the state of the process is detected by monitoring viscosity and/or aggregate size and/or content of a dispersion of proteins, crystalline particles or fat droplets that are processed, respectively. The micro-organisms and/or bio-molecules produced in the process, and the proteins, crystals particles or fat droplets being processed are monitored by means of acoustic spectroscopy.
Claims23
A method for monitoring and controlling viscosity and/or aggregate size and/or content of dispersions of proteins, crystalline particles or fat droplets during processing, the method comprising:
- monitoring at least a part of the proteins and/or crystalline particles and/or fat droplets with acoustic spectroscopy utilizing acoustic waves having a frequency range of 0 to 20 kHz.
A device for monitoring and controlling viscosity and/or aggregate size and/or content of a dispersion of proteins, crystalline particles or fat droplets during processing thereof, the device comprising:
- a means for subjecting the dispersion to acoustic spectroscopy utilizing acoustic waves having a frequency range of 0 to 20 kHz.
Use of acoustic spectroscopy for monitoring a process, the use comprising detecting a state of the process by monitoring viscosity and/or aggregate size and/or content of dispersions of proteins, crystalline particles or fat droplets that are processed, wherein the acoustic spectroscopy utilizes acoustic waves having a frequency range of 0 to 20 kHz.
Use of acoustic spectroscopy for monitoring a process, which is a process for the production of a food product, the use comprising monitoring the product with acoustic spectroscopy utilizing acoustic waves having a frequency range of 0 to 20 kHz.
