Devices containing allyl isothiocyanate against the growth of spoilage and mycotoxigenic fungi in mozzarella cheese
2018
Filter paper and stickers containing allyl isothiocyanate (AIT), as well as pouches containing mustard meal and water for intrinsic production of AIT, were tested against aflatoxigenic strains of Penicillium digitatum CECT 2954 and Aspergillus parasiticus CECT 2681 in sliced mozzarella. Slices were inoculated with either fungus, packaged in plastic bags or plastic trays with one antimicrobial device (2–16 µL/L of AIT). Control groups presented visual growth of P. digitatum after 19.0 ± 1.5 d in bags and 26.1 ± 2.1 d in trays. A. parasiticus was visually detectable after 41.4 ± 1.7 d and 28.4 ± 1.5 d in trays and bags, respectively. AIT‐treated samples did not present visual fungal growth fo…
Shelf life improvement of the loaf bread using allyl, phenyl and benzyl isothiocyanates against Aspergillus parasiticus
2017
Abstract Fungal growth inhibition and aflatoxins (AFs) reduction using allyl (AITC), benzyl (BITC) and phenyl (PITC) isothiocyanates were studied in loaf bread contaminated with Aspergillus parasiticus . Two inoculated loaf bread slices were introduced into a plastic tray together with paper filters or small plastic bags paper filters soaked with AITC, BITC or PITC, the final concentration inside the package was of 0.5, 1 or 5 μL/L. The plastic trays, incubated at room temperature, were visual examined for the shelf life evaluation during 8 days. The quantification of the AFs was carried out using liquid chromatography coupled to mass spectrometry (LC-MS/MS). Shelf life increase of three an…
The effectiveness of Opuntia ficus-indica mucilage edible coating on postharvest maintenance of ‘Dottato’ fig (Ficus carica L.) fruit
2017
Abstract Breba figs are highly perishable and their shelf-life is very short. In this study, breba figs (cv. ‘Dottato’) were treated with a mucilage solution of Opuntia ficus-indica cladodes, sealed in plastic bags, and stored at 4 °C for 14 days. The effect of the edible coating on the shelf-life and qualitative attributes of the fruit were evaluated by colors, content of total soluble solids, titratable acidity, total phenol, total carotenoids. Results showed that coating improves the quality of breba fig during storage. The edible coating was effective in maintaining fruit fresh weight, visual score values, fruit firmness and total carotenoid content. Coated fruit showed a significantly …
