“…This step was performed to allow formulation of the 10% protein test diets with the same amount and source of lipids (maize oil) as in the control diet. Aflatoxin-free soybean (Seridó and Seridó-RCH) samples, confirmed by analysis carried out with a commercial competitive enzyme-linked immunosorbent assay (ELISA) kit [ 20 ], were ground in a hygienized blender and then refined using a coffee grinder (mesh size 1.0 mm). Powdered diets (1 kg) were formulated to contain the equivalent of 100 g protein per kilogram of diet ( Table 1 ) in the form of EW protein or seed meal from cv.…”

Increased Levels of Antinutritional and/or Defense Proteins Reduced the Protein Quality of a Disease-Resistant Soybean Cultivar

The biochemical and nutritional attributes of two soybean (Glycine max (L.) Merr.) cultivars, one susceptible (Seridó) and the other resistant (Seridó-RCH) to stem canker, were examined to assess whether the resistance to pathogens was related to levels of antinutritional and/or defense proteins in the plant and subsequently affected the nutritional quality. Lectin, urease, trypsin inhibitor, peroxidase and chitinase activities were higher in the resistant cultivar. Growing rats were fed with isocaloric and isoproteic diets prepared with defatted raw soybean meals. Those on the Seridó-RCH diet showed the worst performance in terms of protein quality indicators. Based on regression analysis, lectin, trypsin inhibitor, peroxidase and chitinase appear to be involved in the resistance trait but also in the poorer nutritional quality of Seridó-RCH. Thus, the development of cultivars for disease resistance may lead to higher concentrations of antinutritional compounds, affecting the quality of soybean seeds. Further research that includes the assessment of more cultivars/genotypes is needed.

“…Thus, they pose a potential hazard to consumers' health. The presence of some metabolites and traces of aflatoxin in cashew kernels has been demonstrated (Milhome et al, 2014). It is estimated that about 10% of the annual production of cashew nuts is unsuitable kernels for industrial processing and for human feeding, due to the fungi pres ence, mostly (Adeigbe et al, 2015).…”

There are few reports of transmi ssi on of fungus a ssociated with cashew nuts (Anacardium occidentale L.) in Brazil and worldwide. Thus, the aim of thi s study was to evaluate the incidence and severity of anthracnose on leaves and fruits (nuts) of ca shew, nuts sanitary analysi s, nuts-seedling transmi ssion and pathogenicity of fungi associated with cashew nuts. To this end, leaves and nuts of cashew collected in the cities of Gurupi and Formoso do Araguaia , Tocantins state, Brazil, were used. The anthracnose average incidence and disease index were evaluated by observing the typical symptom s of the disease. The nuts were subjected to sanity analysi s, by the filter paper method and transmi ssion test via nuts for the seedlings. High anthracnose incidence and severity were observed in leaves and cashew s nuts. Aspergillus sp. Cladosporium sp. and Colletotrichum gloeosporioides showed high incidence in all nuts samples analyzed. There was high anthracnose transmi ssion by the nuts for the seedlings. Only C. gloeosporioides was pathogenic to ca shew seedlings. Higher germination rates were observed with lower levels of lesions on the external surface. The fungal association with cashews nuts damaged generally normal seedlings development and quality.

“…Implementation of good manufacturing practices in the nut production chain is very important so that the nuts comply with limits of the importers [13]. As a result, many countries have conducted research on the diversity of aflatoxigenic fungi as well as the extent of aflatoxin contamination in edible nuts as well as their products to ensure that their produce meets the required standards [14]. This chapter looks at the nutritional profile, mycotoxigenic fungi and aflatoxins contamination of peanuts, cashew nuts and their products with a central focus on Africa where the effect of aflatoxin contaminations is more prominent.…”

Edible nuts are popular worldwide based on their varied attributes such as desirable taste, high nutritional value as well as some health benefits. Globally, the most popular edible nuts are groundnuts or peanuts, almond, cashew nut among others. Due to the rich nutritional composition of nuts, they tend to be prone to contamination by toxigenic fungi which could ultimately results in the release of fungal metabolites known as mycotoxins into nuts. In view of the nutritional composition of nut and its high susceptibility to fungal attack, this chapter looks at the nutritional profile, mycotoxigenic fungi and aflatoxins contamination of peanuts, cashew nuts and their products with a central focus on Africa where the effect of aflatoxin contaminations is more prominent.
