Non-invasive methods based on physical principles, couple with multivariate analysis, have shown the potential to measure several parameters in a single measurement. Most of these methods are based on vibrational/rotational (infrared), electronic (ultraviolet (UV)-visible), and nuclear magnetic resonance spectroscopies [6]. Among these methods, near-infrared (NIR) spectroscopy from 1000 to 2500 nm is one of the most popular. NIR absorption is assigned to the overtone or combination bands of the fundamental vibrational and rotational transitions [7]. The NIR spectrum shows broad bands associated with combinations of vibration modes (O-H, N-H, and C-H), and overtones of molecular vibrations can be used to determine the parameters of concentrations of fruit quality [8]. Handheld NIR sensors (NIRS) have been used to provide non-destructive real-time and in-field information to optimize harvesting times for greater quality during on-tree ripening [9]. Rapid screening and characterization of major quality parameters of tomatoes have been increasing due to spectrometer portability and miniaturization of optical sensor technology. Novel low cost-effective, non-invasive, robust, and faster spectrometers have been developed, becoming the leading instrument for fruit and vegetables quality screening in the field [10; 11]. Research on the applications of portable NIR systems to determine the quality attributes of fruits and vegetables has increased in the last few years [12; 13; 14; 15; 16]. Portable NIR spectrometers have been applied to measure firmness, soluble solid content (SSC), and/or pH in strawberries [17], plums [18], oranges [19; 20], tomatoes [21], and bell peppers [22]. Also, handheld spectrometers were successfully applied to evaluate moisture and fat content of fresh olives [23; 24] and to classify the maturity stage in avocados [25]. We report on the performance of a novel micro-electro-mechanical systems (MEMS) approach to miniaturize optical, mechanical, and hardware components of large and stationary spectrometers [9; 26]. MEMS integrates mechanical elements, sensors, actuators, and electronics technologies that enable rotation of miniature gratings, measure spectra at millisecond time resolution, and co-add several scans to one spectrum, generating a good signal-to-noise ratio [27]. By using an extended InGaAs (Indium Gallium Arsenide) detector, the MEMS spectrometer can collect spectra in the long-wavelength NIR region (1350 to 2500 nm) which consists of sharper bands associated to combinations or first overtones of the OH, CH, and NH modes.
