“…Saffron is a highly laborious crop, requiring lots of meticulous work and manual operations. The drying of the stigmas also has to be conducted at low temperatures (below 55 • C) to maintain all the benefits [25][26][27]. Not keeping the basal part of the stigmas intact is what leads to quality compromise.…”

Saffron, one of the most expensive crops on earth, having a vast domain of applications, has the potential to boost the economy of India. The cultivation of saffron has been immensely affected in the past few years due to the changing climate. Despite the use of different artificial methods for cultivation, hydroponic approaches using the IoT prove to give the best results. The presented study consists of potential artificial approaches used for cultivation and the selection of hydroponics as the best approach out of these based on different parameters. This paper also provides a comparative analysis of six present hydroponic approaches. The research work on different factors of saffron, such as the parameters responsible for growth, reasons for the decline in growth, and different agronomical variables, has been shown graphically. A smart hydroponic system for saffron cultivation has been proposed using the NFT (nutrient film technique) and renewable sources of energy.

“…Not keeping the basal part of the stigmas intact is what leads to quality compromise. Due to the lack of proper storage houses adjacent to the farms, the crop is not stored as per scientific norms in cool, dark, and dry places, hence leading to adulteration [27][28][29].…”

“…Although the TLC method has matured, it still has shortcomings, such as a low detection accuracy, volatility during the experiment being harmful to the experimental operators and the environment, and complex sample pretreatment [ 124 , 125 ]. In recent years, an interdisciplinary approach, such as the combination of TLC with image analysis and with new technologies, such as surface-enhanced Raman spectroscopy, mass spectrometry, and nuclear magnetic resonance, has further promoted the development of thin-layer chromatography and enhanced the practicability of this method in food analysis [ 126 , 127 , 128 , 129 ]. TLC is used to detect harmful substances in various foods, such as AF in edible oil, making it an effective analytical tool in food science methods [ 124 , 130 ].…”

Contamination of agricultural products and foods by aflatoxin B1 (AFB1) is becoming a serious global problem, and the presence of AFB1 in edible oil is frequent and has become inevitable, especially in underdeveloped countries and regions. As AFB1 results from a possible degradation of aflatoxins and the interaction of the resulting toxic compound with food components, it could cause chronic disease or severe cancers, increasing morbidity and mortality. Therefore, rapid and reliable detection methods are essential for checking AFB1 occurrence in foodstuffs to ensure food safety. Recently, new biosensor technologies have become a research hotspot due to their characteristics of speed and accuracy. This review describes various technologies such as chromatographic and spectroscopic techniques, ELISA techniques, and biosensing techniques, along with their advantages and weaknesses, for AFB1 control in edible oil and provides new insight into AFB1 detection for future work. Although compared with other technologies, biosensor technology involves the cross integration of multiple technologies, such as spectral technology and new nano materials, and has great potential, some challenges regarding their stability, cost, etc., need further studies.

“…As for the supervised analysis for adulteration distinction, PLS‐DA and LDA have been successfully applied for the prediction of adulteration in an international and expensive herb‐saffron 81 . Two supervised pattern recognitions equipped with thin liquid chromatography (TLC) technique effectively distinguish between the authentic saffron and common counterfeit in the international market.…”

“…In addition, the PLS‐DA combined with modern techniques also have been published in other authenticity discrimination study including Notoginseng Radix et Rhizoma adulterated with low‐quality materials, 82 Rhei Radix et Rhizoma with its counterfeit materials, 83 Gastrodiae Rhizoma with its confused materials, 40 and so on. What is more, there are other supervised pattern recognition such as SVM, 84,85 ANN, 84,86 LDA, 81,82,87,88 SIMCA, 79,87,89 and KNN 84,86 for prediction of the adulteration.…”

Herbal medicine has obtained great attention for its effective efficacy using its crude materials and patent medicines. It is believed that the efficacy is a synergetic action by several chemical components. To present a detailed overview of the usage of multivariate statistical techniques developed for analytical chemistry in quality assessment and origins traceability, we provided an extensive pragmatic and practical overview of these techniques for the quality control of these crude medicines. Two pattern recognition methods, unsupervised and supervised approaches, were interpreted using practical instances. Overall, the review briefly summarized common applications for location, species, harvesting time, processed production, manufacture, botanical part, and authenticity. Besides, we focused on data pretreatment and fusion strategies listing recently published literature to provide a detailed reference to choose the most appropriate statistical method and fusion strategies. Actual applications have proved chemometrics as an effective and rapid tool for the quality control of herbal medicine.
