Nowadays, the importance of food quality and human health is a major priority. Consumers are concerned with food composition (for example high carbohydrate/fat content or low protein content) and its authenticity, origin, as well as the traceability of both food and pharmaceuticals, which are obtained in various modern industries.

In the field of food and pharmaceutical sciences, the combination of instrumental techniques and multivariate data analysis has an important role to play in the manufacturing process and in the control and monitoring of the various stages of the food and pharmaceutical chain. The most effective applications of chemometrics in the research and technology of functional foods and pharmaceuticals are those related to the measurement of several compositional parameters based on instrumental methods of analysis. Moreover, chemometrics is of utmost importance to evaluate the authenticity of foodstuffs. The advantages or predictive capacity of multiple parameters have made significant contributions to the development of most applications currently used by the food and pharmaceutical industry, as well as the emergence of new applications. With the development of new analysis tools and techniques, new analytical strategies, such as profiling and fingerprinting, contribute to obtaining a large volume of data that characterises the studied systems.

This Special Issue aims to collate original research papers and reviews related to the development of new multivariate and multidirectional methods, as well as methodological aspects, of chemometrics research, aimed at optimising chemical systems, selection of process variables and fusion of experimental data. Application-oriented works related to chemometrics used in various fields related to the food and pharmaceutical industry are also welcome.

Potential topics include but are not limited to the following:

• Applications of chemometrics
• Exploratory data analysis
• Identification of chemical compounds
• Model optimisation
• Multivariate calibration
• Multivariate methods
• Multiway methods
• Nutraceuticals
• Sustainable functional food production
