Abstract
The invention relates to a system and method for controlling an enzymatic pre-treatment process, e.g. a mashing process. The system and method provide for accurate determination of specific sugar molecules as well as the average length of the sugar chains in real-time during e.g. a mashing process. Further information on, e.g., the concentration of dissolved protein and free amino acids can also be obtained simultaneously.
Claims20
A system for controlling an enzymatic pre-treatment process, the system comprising:
- an analyzing unit configured to be connected in fluid communication, on-line and/or in-line with a container, and connected to an IR spectrometer, the analyzing unit configured for bringing a sample mixture into direct contact with the IR spectrometer for measuring attenuated total reflectance (ATR) IR spectra of a liquid part (solutes and solvents) of the sample mixture during an enzymatic pre-treatment process, and
- a calculation unit connected with the IR spectrometer, the calculation unit being adapted for calculating:
- a ratio between specific species in the sample mixture based on the IR spectra of the sample mixture, and/or
- a concentration of one or more specific species based on the IR spectra of the sample mixture, and/or
- a degree of polymerization of one or more of specific species based on the IR spectra of the sample mixture.
