Aflatoxin, microbial contamination, sensory attributes, and morphological analysis of pistachio nut coated with methylcellulose

Abstract

Pistachio is one of the most popular nuts globally (Wu & Xu, 2020) grown in different countries such as Iran, the USA, Turkey, Syria, Italy, and Greece (Catalán et al., 2017). It contains high amounts of phenolic compounds with unique efficiency and high antioxidant potential (Wu et al., 2018). However, this valuable product is very susceptible to rancidity and molds' contamination (Holakouie Naieni et al., 2020).Contamination by storage pests is a significant problem faced with this product. Mold contamination in crops leads to the formation of critical secondary metabolites named mycotoxins, which are secondary metabolites of different fungus including Aspergillus flavus, Aspergillus parasiticus, Aspergillus tamarri, Aspergillus bombycitts, and Aspergillus nomius. These funguses produce different aflatoxins including B1, B2, G1, and G2. The metabolites mentioned above increase the risks of cancer and mutation in humans and animals (Ortega-Beltran et al., 2019).

The synergistic effects of zinc oxide nanoparticles and fennel essential oil on physicochemical, mechanical, and antibacterial properties of potato starch films

“…Plant essential oils (EOs) extracted from different parts of plants have a complex combination of various active and aromatic compounds (Chang et al., 2021; Plant et al., 2019). EOs often demonstrate significant antimicrobial and antioxidant activities and can be used as a substitute for synthetic preservatives in the food industry (Moslehi et al., 2021; Mousavian et al., 2021). Sun et al.…”

The effects of nano‐zinc oxide morphology on functional and antibacterial properties of tapioca starch bionanocomposite

“…Petroleum polymers have significant thermal, inhibitory, and mechanical properties and relatively low price and easy processing capability. Therefore, these polymers are widely used in the packaging industry (Abdullah & Dong, 2019 ; Araghi et al., 2015 ; Moslehi et al., 2021 ; Mousavian et al., 2021 ). However, plastic waste is on the rise and is likely to reach more than 12,000 million metric tons by 2050 (Geyer et al., 2017 ).…”

The effects of methylcellulose coating containing carvacrol or menthol on the physicochemical, mechanical, and antimicrobial activity of polyethylene films

“…These active systems often contain active compounds that can be released into the interior of packaging. This type of packaging system usually uses active ingredients derived from natural sources that have antioxidant and/or antimicrobial activities (Lukic et al., 2020; Moslehi et al., 2021). However, in order to prepare active packing from synthetic polymers, bioactive compounds cannot be used directly in the production stages of these polymers because the performance of these active agents is reduced due to the high temperatures used for processing.…”
