“…The cashew nut also showed a high rate of retention of viral infectivity following incubation on the item's surface ( Figure 2 ), which could be related to the high oil, protein, and carbohydrate content of the nut (48.3%, 21.3%, and 20%, respectively) ( Rico, Bulló & Salas-Salvadó, 2016 ). According to Muniz et al (2013) , the cashew nut (cotyledon) surface is covered with starch grains and oil bodies distributed across parenchymal cells. Possibly, SARS-CoV-2 can be trapped in these oil and starch structures and be preserved from inactivation.…”

“…In the case of the X ‐ and Y ‐axis ( X ‐axis is the length of grain, and Y ‐axis is the width), a reduction in hardness can be noticed, while an increase has been observed when compression occurs along the Z ‐axis. Considering our results, we suggest that the additional water that was absorbed over time filled the spaces inside the nut (mesocarp) making it structurally turgid, which resulted in an increase in the hardness of the material (Altuntaş & Yildiz, 2007; Muniz et al ., 2013).…”

Starch-based films incorporated with cellulose nanofibres (CNFs) were tested as packaging to improve the stability of cashew nut kernels (CNKs). CNKs were conditioned in four packings: commercial polyethylene film (PEF), starch film (CF), nanocomposite CHF (starch + CNFs from chemical hydrolysis) and nanocomposite EHF (starch + CNFs from enzymatic hydrolysis). Effect of the packaging methods on peroxides value (POV), acidity value (AV), weight gain (WG), water activity (Aw), hardness and colour properties of the CNKs was investigated. CNKs packed with CHF and EHF showed lower POV (0.91 and 0.92 meq peroxide /kg sample , respectively) after 21 days of storage than other packed (1.07-1.13 meq peroxide /kg sample ) and unpacked samples (1.32 meq peroxide /kg sample ). CNKs packaged with nanocomposites presented similar WG to samples packaged with PEF and lower values than unpackaged CNKs. Biodegradable nanocomposites films showed potential to be used as packaging for food product, being an effective material for extending oilseeds shelf life.

“…Importantly, the incidence of A. flavus was the most commonly identified species in cashews [40], this finding is similar to our observation. Shells of nuts are the first physical barrier that preventing microbial invasion that explains the susceptibility of unshelled nut samples to fungal contamination [41]. In addition to the matrix structure of cashew, the moisture and nutrient contains including carbohydrates, proteins and lipids that encourage fungal propagules growth, penetration and mycotoxin production [42].…”

Fungal contamination in nuts is unavoidable and is a major challenge to nuts safety, quality and then for human health after consumption particularly immunocompromised individuals. This study aimed to early detection of potential pathogenic Aspergillus in nuts to avoid the harmful effects of allergens and mycotoxins. Three different geographic locations in Basra, Iraq were screened, and a total of 28 fungal isolates were recovered from tested nuts including cashews, almonds, walnuts, pistachio and sunflower seeds. ELISA was used to identify isolated fungi based on antigenic structure via using a highly specific MAb for Aspergillus, JF5. The accuracy of ELISA was validated by ITS-rDNA sequence in comparison with NCBI database. The highest incidence of isolated fungi belongs to main four genera Aspergillus (78.57%), Alternaria (10.71%), Cladosporium (7.14%), followed by Penicillium (3.75%). The most dominant species was A. flavus, a potential aflatoxins producer, (28.57%). Abu was highly contaminated geographic site comparing with Zubayr and Qarmat. These findings raise awareness about contaminated nuts particularly there is no database available and highlighted the accuracy of using specific MAb for fungal identification and diagnosis. The occurrence of well-known toxigenic species such as A. niger, A. flavus and A. terreus suggested the possible risk of mycotoxin contamination of the nuts for human consumption.
