Abstract
Despite recent advances in food product development (e.g. nutraceuticals and functional foods) our understanding of the role of water in foods is still in its infancy. Monitoring of food quality via optical methods such as near infrared (NIR) and terahertz spectroscopy is made possible due to the interaction of electromagnetic energy and the water matrix. Aquaphotomics provides a framework for understanding the role of water in food systems and processes. This paper highlights the importance of water in food quality and presents a number of case studies that demonstrate the potential of NIR hyperspectral imaging for monitoring food quality through observation of water absorbance bands.
Keywords: water, food, near infrared, quality, hyperspectral, imaging.
