“…The system used in this manuscript (Tellspec, Canada) relies on a three-part system that includes a pocket-sized NIR sensor, a cloud-based patented analysis engine, and a mobile app (10), previously used under different food approaches from macronutrients to allergens and contaminants, giving information on possible fraud, adulteration, and quality of foodstuffs, or even in the quality control of pharmaceutical drugs (11), meat (12), and honey (13). However, there are no available studies regarding its use in citrus fruits.…”

Citrus industry has grown exponentially as a result of increasing demand on its consumption making it stand high among other fruit crops. Therefore, the citrus sector seeks rapid, ease and non-destructive approaches to evaluate in real-time and in situ the external and internal changes in physical and nutritional quality at any stage of fruit development or storage. In particular, vitamin C is among the most important micronutrients for consumers, but its measurement relies on laborious analytical methodologies. In this study, a portable near-infrared spectroscopy (NIRS) sensor was used in combination with chemometrics to develop robust and accurate models to study the ripeness of several citrus fruits (oranges, lemons, clementines, tangerines, Tahiti limes) and their vitamin C content. Ascorbic acid, dehydroascorbic acid and total vitamin C were determined by HILIC-HPLC-UV, while soluble solids and total acidity were evaluated by standard analytical procedures. Partial least squares regression (PLSR) was used to build regression models which revealed suitable performance regarding the prediction of quality and ripeness parameters in all tested fruits. Models for ascorbic acid, dehydroascorbic acid, total vitamin C, soluble solids, total acidity and juiciness showed Rcv2 = 0.77 – 0.87, Rcv2 = 0.29 – 0.79, Rcv2 = 0.77 – 0.86, Rcv2 = 0.75 – 0.97, Rcv2 = 0.24 – 0.92, and Rcv2 = 0.38 – 0.75, respectively. Prediction models of oranges and Tahiti limes showed good to excellent performance regarding all latent variables. The resulting models confirmed that NIRS technology is a time and cost-effective approach to predict citrus fruit quality, which can easily be used by the various stakeholders from the citrus industry.

“…Tellspec scanner (950-1630 nm) was used to generate NIR spectra for Hungarian honey. They classified different honey samples and found 92.61% prediction ability based on the NIR spectra model (Kaszab et al, 2017). Tellspec (900-1700 nm) and SCiO (740-1070 nm) were used to predict sugarcane properties (total sugar content) based on spectrum and compared their result with standard Lab-Spec (350-2500 nm) (Figure 3c).…”

The instantaneous detection of food quality is of paramount importance as it can help in taking different decisions in real time. These include the decision on consumption, inventory management, maintaining the storage conditions and even to repurpose the food if it cannot be used for the desired application. In this review, different portable food diagnostic devices and methods are studied and compared as consumers are interested in knowing the food's quality before consumption. The quality of food in real‐time will help in avoiding many problems such as the consumption of unsafe food and taking prompt decisions to avoid wastage in the food supply chain. Portable food diagnostic devices provide advantages such as easy to use, compact, handheld, connectivity with smartphone for rapid diagnosis, as well as these devices have the potential to eliminate traditional method problems such as the requirement of a trained user, bulky equipment, and lengthy diagnosis procedure. In this study, different types of portable food diagnostic devices and methods are compared in terms of their working principle, features, applications, and limitations. These devices are classified in three main categories, as composition analysis, safety, and security based on application. Further these devices are subclassified in single/multiple composition analysis devices, toxic, allergen detecting devices, and methods. Portable food diagnostic devices and methods provide a rapid and on‐site diagnosis. However, the success of these devices depends upon their accuracy, simplicity, and cost‐effectiveness. Practical Applications The study provides comparative analysis of different portable food diagnostic devices, which help in selecting an appropriate device in terms of its accuracy, size and cost suitable under different supply chain scenarios. This will ultimately help in decision making required for minimizing the food losses. These devices will benefit farmers, suppliers, retailers, and operators in food processing industries. The individual users can also use these devices to manage the food quality. The study also provides the limitations of exiting devices and the need of new research for developing more compact devices measuring multiple constituents in the food in a precise and cost‐effective manner.

“…Honey is the other product of animal origin that received some attention. Using a range between 950 and 1630 nm, Kaszab et al, 2017 [ 95 ], were able to predict 100% of the floral origin of honeys, i.e., linden, acacia, polyfloral, and chestnut honey. Similarly, the geographical origin could be predicted with a success rate of 96%.…”

This review summarises miniaturised technologies, commercially available devices, and device applications for food authentication or measurement of features that could potentially be used for authentication. We first focus on the handheld technologies and their generic characteristics: (1) technology types available, (2) their design and mode of operation, and (3) data handling and output systems. Subsequently, applications are reviewed according to commodity type for products of animal and plant origin. The 150 applications of commercial, handheld devices involve a large variety of technologies, such as various types of spectroscopy, imaging, and sensor arrays. The majority of applications, ~60%, aim at food products of plant origin. The technologies are not specifically aimed at certain commodities or product features, and no single technology can be applied for authentication of all commodities. Nevertheless, many useful applications have been developed for many food commodities. However, the use of these applications in practice is still in its infancy. This is largely because for each single application, new spectral databases need to be built and maintained. Therefore, apart from developing applications, a focus on sharing and re-use of data and calibration transfers is pivotal to remove this bottleneck and to increase the implementation of these technologies in practice.
