In line monitoring of red wine fermentations using IR spectroscopy

In line monitoring of red wine fermentations using IR spectroscopy

There has been a shift in modern industry to implement non-destructive and non-invasive process monitoring techniques. This is primarily to ensure that process conditions are maintained at optimal set points, thus improving consistency, efficiency and control. Implementation of infrared technology and chemometrics in the wine industry has been extensively studied and has been found to be a suitable method of process monitoring, especially when considered in the context of phenolic extraction. However, these studies have conducted spectroscopic analysis off-line and with highly clarified samples . For the technology to be more applicable to a real life scenario, a shift towards in-line monitoring must be made. The ultimate aim of this study was the development of an automated sampling and analysis system would allow this technology to become more commonly used in commercial cellars and for precision monitoring of phenolic extraction.
