“…Therefore, resistance evaluations are necessary across multiple years or locations (Buerstmayr et al, 2008; Yan et al, 2022). Cluster analysis is a method for dividing a group of objects into classes so that similar objects are in the same class (Gupta et al, 2022; Kalogiouri et al, 2021), while discriminant analysis is a multivariate analysis used to find the linear combination of features that distinguish two or more classes (Huberty, 1975; Stella, 2019). Combining cluster analysis with discriminant analysis helps to improve the accuracy of classification.…”

Sugarcane pokkah boeng disease (PBD), caused by a Fusarium species complex, is one of the most critical diseases causing a significant economic loss of sugarcane production in China. It is important to standardize the evaluation method for screening sugarcane cultivars for resistance to PBD. Field trials were conducted to investigate the occurrence of sugarcane PBD in different months and growth stages from 2018 to 2019 and to evaluate the PBD resistance of 169 sugarcane genotypes from 2019 to 2022. PBD mainly occurred in the early and middle elongation stages at a plant height of approximately 1-2 m. The most severe and common incidence of PBD was from June to August. Variance analysis showed genotype, year and the interaction of genotype and year had a significant effect on disease incidence and disease index.The 169 sugarcane genotypes were divided into five categories by cluster analysis and discriminant analysis, of which 33 were rated as highly resistant, 37 as resistant, 38 as moderately susceptible, 26 as susceptible and 35 as highly susceptible. These findings enhance our understanding of sugarcane resistance to PBD and lay the foundation for breeding new resistant varieties.

“…are well-known superfoods; they are an excellent source of protein, fiber, fats, vitamins, and minerals. Literature research showed an increasing interest in studying the elemental composition of nuts for geographical origin authentication [ 193 , 194 , 195 , 196 , 197 , 198 ] the last five years. The first attempt to classify hazelnuts according to their geographical origin was accomplished by Oddone et al [ 193 ], in 2009.…”

Fraudulent practices are the first and foremost concern of food industry, with significant consequences in economy and human’s health. The increasing demand for food has led to food fraud by replacing, mixing, blending, and mislabeling products attempting to increase the profits of producers and companies. Consequently, there was the rise of a multidisciplinary field which encompasses a large number of analytical techniques aiming to trace and authenticate the origins of agricultural products, food and beverages. Among the analytical strategies have been developed for the authentication of geographical origin of foodstuff, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) increasingly dominates the field as a robust, accurate, and highly sensitive technique for determining the inorganic elements in food substances. Inorganic elements are well known for evaluating the nutritional composition of food products while it has been shown that they are considered as possible tracers for authenticating the geographical origin. This is based on the fact that the inorganic component of identical food type originating from different territories varies due to the diversity of matrix composition. The present systematic literature review focusing on gathering the research has been done up-to-date on authenticating the geographical origin of agricultural products and foods by utilizing the ICP-MS technique. The first part of the article is a tutorial about food safety/control and the fundaments of ICP-MS technique, while in the second part the total research review is discussed.

Nuts used as a snack and meal accompaniment supply plant protein and fatty acids that are beneficial for human health; however, they can also provide minerals. The aim of this study was to determine the content of selected elements that are often deficient in the diet (calcium, potassium, magnesium, selenium, and zinc) in nuts and determine whether they can be used to supplement deficiencies in the diet. In this study, we analyzed 10 types of nuts (n = 120 samples) that are consumed and available for sale in Poland. The content of calcium, magnesium, selenium, and zinc was determined by the atomic absorption spectrometry method, and flame atomic emission spectrometry was used for determination of potassium contents. The highest median calcium content was found in almonds (2825.8 mg/kg), the highest potassium content in pistachio nuts (15,730.5 mg/kg), the highest magnesium and selenium contents in Brazil nuts (10,509.2 mg/kg and 4348.7 μg/kg, respectively), and the highest zinc content in pine nuts (72.4 mg/kg). All the tested nuts are a source of magnesium, eight types of tested nuts are a source of potassium, six nut types are a source of zinc, and four nut types are a source of selenium; however, among the tested nuts, only almonds can be considered a source of calcium. Moreover, we found that selected chemometric methods can be useful in the classification of nuts. The studied nuts are valuable products that can be used to supplement the diet with selected minerals and can therefore be labelled as functional products crucial for disease prevention.
