A method and apparatus for monitoring and/or controlling a process involving food and/or beverages. Infrared spectroscopic analysis equipment, preferably MID-IR equipment, provides spectroscopic data, covering a period of time (Fig. 1). The process procedes e.g. in a fluid or medium, in a reactor, the spectroscopic data relating to the fluid or medium in the reactor. The process may be a batch process, such as a dairy process. The data are evaluated by use of curve resolution, such as multivariate curve resolution, e.g. Alternating Least Squares (ALS), or Alternating Regression (AR). The method may be used for determination of the properties of and/or constituents during the process and/or for monitoring, and especially for on-line monitoring of the process by storing and processing spectroscopic data collected for a plurality of discrete time slices during a period of time. The advantage is that the data can be evaluated without the need for reference analyses. |
