Recent Advances of Near Infrared Applications in Fruits and Byproducts

About this Research Topic

Near infrared spectroscopy (NIRS) has been widely applied to fruit and fruit byproducts in order to ensure their safety and quality. In the last decades, mainly benchtop devices have been utilized for the development of at-line methods for qualitative and quantitative control. These methods have been limited by the chemical and physical heterogeneity of samples with high moisture content and high seasonal and regional variations. Recent advances in NIRS, such as improvements in sensors, new grating materials, new chemometric procedures, etc., have allowed the emergence of new devices and methodologies. Simpler, faster and more accurate models are being obtained. In addition, more complex parameters are being tested (detection of contaminants at trace level, extractabilities of interesting compounds or characterization of individual compounds within a family). As a result, imaging and spot NIRS have driven both portable and online use in the fruit industry.

In the present context, it is essential to apply new NIRS technologies to the improvement of non-destructive and non-polluting methods for the control and assurance of safety and quality in the fruit and fruit byproducts industry. It is necessary to develop simpler, faster and more accurate models for monitoring complex parameters in these matrices. To achieve these objectives, hyperspectral or multispectral imaging systems can be used to usefully include spatial information from samples into models; portable and handheld systems can be used to make NIRS methods portable without significant loss of accuracy; and new chemometric approaches should be used to select samples or variables, classify samples, develop linear or non-linear regressions, etc. to obtain computationally simple methods. Finally, updates or transfers of old NIRS methods can be developed for use in current and more accurate devices. These activities will produce a high impact in the fruit and fruit byproducts industry in a near future.

The scope of this research topic consists of the application of new NIRS technologies to the improvement of non-destructive and non-polluting methods for the control and assurance of safety and quality in the fruit and fruit byproducts industry. We would like to invite all article types, particularly Original Research and Review articles on the following topics:

• Application of near infrared hyperspectral or multispectral imaging devices
• Use of NIR portable systems for in situ detection
• Development of online or inline NIR applications
• Control of complex parameters such as contaminants at trace level, extractabilities, individual compounds within a family, etc.
• Application of new chemometric approaches


Keywords: near infrared spectroscopy, fruit, byproducts, sensing
