We evaluate the use of a portable and non-invasive technology based on visible and near infrared (vis/NIR) spectroscopy (Cherry-Meter) for monitoring fruit maturity parameters and anthocyanins in two highbush blueberry (Vaccinium corymbosum L.) cultivars (Misty and Sharpblue). This device measures an Index of Absorbance Difference (I AD ), which showed high correlations with fruit quality parameters in other fruit crops. We found positive but differential correlations between I AD values and fruit anthocyanins, which was higher for Misty (r = 0.970, p≤0.01) than for Sharpblue (r = 0.714, p>0.05). Interestingly, Cherry-Meter measurements were also correlated with solid soluble concentrations (r = 0.685, p≤0.01) and fruit firmness (r = -0.714, p≤0.01), but only in Sharpblue. For both cultivars, I AD values were also significantly (p≤0.01) related with fruit FW (0.447 for Sharpblue and 0.559 for Misty). The High Performance Liquid Chromatography (HPLC) data indicated that I AD variations were associated with significant changes in single berry anthocyanidins levels. These findings are the first approach, highlighting the potentialities of Cherry-Meter for the non-destructive assessment of fruit maturity and anthocyanidin profile in blueberries.

“…The authors in a previous study [13] tested a variable selection methodology in order to select a reduced set of effective variables for the monitoring of red grape ripening using vis/NIR spectroscopy. The obtained determination coefficients and RPD values showed a similar trend to those of the present work: for the PLS and MLR, R 2 ¼0.77, RPD ¼2.26 and R 2 ¼0.71, RPD¼ 2.13 were obtained, respectively, for SSC prediction.…”

“…Liu et al [11] proposed three effective wavelength selection methods combined with vis/NIR spectroscopy in order to determine the soluble solids content of beer. The authors already tested different variables selection approaches in previous studies in order to identity effective wavelengths to monitor quality decay in fresh-cut lamb's lettuce [12], to estimate ripening parameters on wine grapes [13] and blueberries [14], in a view of simplified optical systems.…”

“…The main differences between these types of NIR devices and an overview of spectroscopy applications on fruits and vegetables based on the instrumental characteristics of the NIR devices employed for the studies can be found in Beghi et al (2017). The literature shows that many applications of VIS-NIR spectroscopy involve the use of benchtop and portable full spectra devices, but recent studies have been conducted using simplified optical systems based on a small number of wavelengths (Beghi et al, 2013;Giovenzana et al, 2014;Civelli et al, 2015). This topic is discussed in Beghi et al (2017).…”

Background The increasing demand for quality assurance in agro-food production requires sophisticated analytical methods for in-line quality control. One of these techniques is visible and near-infrared (VIS-NIR) spectroscopy, which has low running costs, does not need sample preparation, and is non-destructive, environmentally friendly, and fast. Despite these advantages, only a limited amount of research has been conducted on VIS-NIR in-line applications to measure, control, and predict quality in fruits and vegetables. Scope and Approach The applicability of VIS-NIR spectroscopy for the off-line and in-line monitoring of quality in postharvest products has been addressed in this review. The document focuses on the comparison between the two processes for the same agro-food product, highlighting the main advantages and disadvantages, problems, solutions, and differences. Key Findings and Conclusions VIS-NIR techniques, combined with chemometric methods, have shown great potential due to their fast detection speed, and the possibility of simultaneously predicting multiple quality parameters or distinguishing between products according to the objectives. Being able to automate processes is a great advantage compared to routine off-line analyses, mainly due to the savings achieved in time, material, and personnel. However, in numerous cases, in-line implementation has not been accomplished in the corresponding studies, hence the scarcity of real in-line applications. Recent demands, together with the advances being made in the technology and a reduction in the price of equipment, makes VIS-NIR technology an analytical alternative for continuous realtime food quality controls, which will become predominant in the next few years.
