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.

1. 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. 2. The method according to claim 1, wherein the process is controlled by means of heat and/or pH and/or pressure adjustment based on the result of the acoustic spectroscopy.3. The method according to claim 1, wherein the dispersion subjected to the acoustic spectroscopy is conducted through a tube.4. The method according to claim 1, wherein the acoustic waves that the dispersion is subjected to are transmitted in a direction along the axis of the tube.5. The method according to claim 1, wherein the dispersion comprises proteins subjected to denaturation in a process for preparing a food product.6. The method according to claim 1, wherein the dispersion comprises proteins subjected to denaturation in a process for preparing a dairy product.7. The method according to claim 1, wherein the dispersion comprises fat droplets subjected to a homogenisation process of preparing a food product.8. The method according to claim 1, wherein the measurement by means of acoustic spectroscopy is an on-line measurement executed in a process line in which said process takes place.9. The method according to claim 1, wherein the dispersion is also subjected to an ultrasonic measurement and that the process is controlled based on the acoustic spectroscopy with regard taken to the result of the ultrasonic measurement.10. 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. 11. The device according to claim 10, wherein it comprises a tube through which the dispersion flows while being subjected to the acoustic spectroscopy.12. The device according to claim 10, wherein the tube is a tube in a process line for the production of a food product.13. The device according to claim 10, wherein it comprises an ultrasonic transducer for transmitting ultrasonic waves through the dispersion that is subjected to the acoustic spectroscopy.14. 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.15. 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.16. The method according to claim 1, wherein the acoustic waves have a frequency range of 100 to 5000 Hz.17. The method according to claim 1, wherein the acoustic waves have a frequency range of 100 to 3300 Hz.18. The device according to claim 10, wherein the acoustic waves have a frequency range of 100 to 5000 Hz.19.
