“…Digital color imaging, X‐ray imaging, near‐infrared (NIR) spectroscopy, fluorescence spectroscopy, NIR hyperspectral imaging (HSI) are the main techniques for nondestructive detection of microbial contamination in food products (Liu et al., 2018; Tripathi & Mishra, 2009). Although there are several reviews on the application of optical imaging and spectroscopic techniques on quality and safety evaluation of food products (Dale et al., 2013; Kaavya et al., 2020; Liu, Pu & Sun, 2017; Ma, Sun, Pu, Cheng & Wei, 2019; Sendin, Williams & Manley, 2018; Singh & Jayas, 2011; Su, He & Sun, 2017; Wu & Sun, 2013b), there are limited reviews on mold and mycotoxin detection in cereal grains and nuts. Orina, Manley, and Williams (2017a) reviewed nondestructive techniques for the detection of fungal infection in cereal grains and Wu, Xie, and Xu (2018) reviewed imaging and spectroscopic techniques for the detection of toxigenic fungi and AFs in nuts and dried fruits.…”

Cereal grains and nuts are represented as the economic backbone of many developed and developing countries. Kernels of cereal grains and nuts are prone to mold infection under high relative humidity and suitable temperature conditions in the field as well as storage conditions. Health risks caused by molds and their molecular metabolite mycotoxins are, therefore, important topics to investigate. Strict regulations have been developed by international trade regulatory bodies for the detection of mold growth and mycotoxin contamination across the food chain starting from the harvest to storage and consumption. Molds and aflatoxins are not evenly distributed over the bulk of grains, thus appropriate sampling for detection and quantification is crucial. Existing reference methods for mold and mycotoxin detection are destructive in nature as well as involve skilled labor and hazardous chemicals. Also, these methods cannot be used for inline sorting of the infected kernels. Thus, analytical methods have been extensively researched to develop the one that is more practical to be used in commercial detection and sorting processes. Among various analytical techniques, optical imaging and spectroscopic techniques are attracting growers' attention for their potential of nondestructive and rapid inline identification and quantification of molds and mycotoxins in various food products. This review summarizes the recent application of rapid and nondestructive optical imaging and spectroscopic techniques, including digital color imaging, X-ray imaging, near-infrared spectroscopy, fluorescent, multispectral, and hyperspectral imaging. Advance chemometric techniques to identify very low-level mold growth and mycotoxin contamination are also discussed. Benefits, limitations, and challenges of deploying these techniques in practice are also presented in this paper.

“…FTIR spectra profile is the molecular fingerprint of the sample that is used to screen and scan many different components. It is one of the effective methods to detect functional groups present in the sample [49][50][51]. FTIR spectroscopy of different pasta samples showed that WGJ enrichment did not significantly [55].…”

Pasta is an excellent source for fortification of ingredients and wheatgrass juice (WGJ) as a natural source of vital nutrients and antioxidants; the study was taken to develop WGJ-rich functional pasta. Wheatgrass juice (WGJ) was added at the rate of 33, 66, and 100% by replacing water during the mixing process of pasta. The samples were assessed by cooking quality, proximate composition, antioxidant properties, color, texture attributes, and sensory evaluation. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were performed. Incorporation of WGJ significantly ( p < 0.05 ) decreased the optimum cooking time of pasta, whereas water absorption capacity was increased. Cooking loss in pasta increased from 2.89 to 3.21% with increasing levels of WGJ from 33 to 100%. The addition of wheatgrass juice to pasta improved the nutritional and antioxidant profile significantly ( p < 0.05 ), as evidenced by increases in protein, phenolics, flavonoids, chlorophyll, and antioxidant activities (FRAP, DPPH, and ABTS). The incorporation of wheatgrass juice reduced the L value, whereas a ∗ of the pasta enhanced gradually. With the addition of WGJ, the stiffness and hardness of the pasta changed dramatically. FTIR spectra validated the existence of bioactive compounds and chlorophyll pigments in pasta. Sensory data revealed that pasta containing 100% of WGJ was acceptable with the highest overall acceptability score of 7.72.

“…Many kinds of damage cannot be detected with a visual inspection alone, thus rendering the process of selecting high-quality products insecure. Conventional testing methods, such as sampling from big lots, are time-consuming and expensive (4)(5)(6)(7). Moreover, a significant amount of product is often destroyed during conventional testing and sampling.…”

The qualitative and quantitative evaluation of agricultural products has often been carried out using traditional, i.e., destructive, techniques. Due to their inherent disadvantages, non-destructive methods that use near-infrared spectroscopy (NIRS) coupled with chemometrics could be useful for evaluating various agricultural products. Advancements in computational power, machine learning, regression models, artificial neural networks (ANN), and other predictive tools have made their way into NIRS, improving its potential to be a feasible alternative to destructive measurements. Moreover, the incorporation of suitable preprocessing techniques and wavelength selection methods has arguably proven its practical feasibility. This review focuses on the various computation methods used for processing the spectral data collected and discusses the potential applications of NIRS for evaluating the quality and safety of agricultural products. The challenges associated with this technology are also discussed, as well as potential future perspectives. We conclude that NIRS is a potentially useful tool for the rapid assessment of the quality and safety of agricultural products.
