Abstract This study addressed the effects of chitosan-based nanoparticles on microbiological quality, colour, polyphenol oxidase (PPO) and peroxidase (POD) firmness fresh-cut ‘Gala’ apple slices during storage at 5 °C for 10 days. The treatments carried out were as follows: (i) pulverised with 110-nm chitosan nanoparticles, (ii) 300-nm (iii) 2 g L−1 dissolved in 2% citric acid (iv) noncoated samples. There was an increase chroma a proportional decrease hue angle lightness. Browning coated...
Carnauba wax nano and micro-sized emulsions hydroxypropyl methylcellulose coatings, alone or combined with ginger essential oils (GEO) were applied on papayas evaluated under several storage conditions. In a first experiment, parameters were: 6 days at 22 °C, 9 13 °C followed by 5 °C. second was: 10 16 3 Coating effects dependent While fruits in cold storage, there few changes; however, the differences between coatings became more evident. Nanoemulsions maintained papaya quality during...
Edible coatings to extend the shelf life and preserve quality of fruit vegetables are highly demanded nowadays. Recently, plant-based edible have gained importance in context sustainability, which combination with suitable top-down process can render "greener" nanoemulsions optimized properties. Herein we developed a carnauba wax nanoemulsion (CWN) by using high-pressure processing be applied as an coating for vegetables. The as-developed properties were compared conventional emulsion (CWM),...
Papaya is a fruit of great importance worldwide. However, significant losses during postharvest have been reported, which can be minimized by applying lipid nanoemulsions as edible coatings associated with natural antimicrobial compounds. These provide barrier to gases and water vapor, in addition improving mechanical properties, thereby delaying senescence minimizing deterioration phytopathogens storage. The aim this study was investigate the preservation potential papaya fruits treated an...
The growing demand for fresh foods, as well the rise in ready-to-eat is leading food industry to study edible coatings maintain quality of fresh-cut fruit. objective this work was, first, determine antimicrobial activity a commercial anti-browning solution (A), chitosan (CH), and nanochitosan (NCH) both vitro vivo and, secondly, assess effects those on nectarines. Antimicrobial was studied against Listeria monocytogenes Saccharomyces cerevisiae, which were used models foodborne pathogen...
Coatings are generally applied to fruit as microemulsions, but nanoemulsions still experimental. ‘Nova’ mandarins ( Citrus reticulata ) were coated with shellac or carnauba Copernica cerifera microemulsions an experimental nanoemulsion; these compared uncoated control during storage for 7 days at 20 °C. also tested on ‘Unique’ tangors C. × sinensis stored 14 10 °C followed by a simulated marketing period of Fruit quality evaluations included weight loss, gloss, soluble solids (SS),...
The clinical characteristics of hereditary nephropathy associated with hyperuricemia or gout have not been fully described, and the pathogenetic role increased serum urate concentration is controversial.We examined 14 patients purine metabolism seven patients, while they were on a purine-restricted diet, in two families asymptomatic gout. Results plasma urinary measurements compared those obtained 25 renal insufficiency normal subjects. Eight subjects both followed up for mean 44 months....
Brazil is the world’s largest orange producer; however, part of this production lost during postharvest. This loss can be minimized by controlling incidence physical damage throughout harvest and loading operations. Impacts negatively modify quantitative qualitative fruits aspects. The main goal study was to measure impact magnitude in two types (manual detachment) all steps from picking into bags until for transport processing industry additionally evaluating, laboratory, physico-chemical...
Different light-based strategies have been investigated to inactivate viruses. Herein, we developed an HIV-based pseudotyped model of SARS-CoV-2 (SC2) study the mechanisms virus inactivation by using two different strategies; photoinactivation (PI) UV-C light and photodynamic (PDI) Photodithazine photosensitizer (PDZ). We used pseudoviral particles harboring Luciferase-IRES-ZsGreen reporter gene with either a SC2 spike on membrane or without as naked control pseudovirus. The mechanism viral...
Mercurials are known to induce morphological and functional modifications in kidney mitochondria. In this work we studied vitro vivo the protective effect of captopril on deleterious Hg(++)-induced nonspecific membrane permeability changes Ca++ de-energization. administration prevented toxic effects mercury poisoning permeability, oxidative phosphorylation homeostasis. Moreover, preserves tissue morphology from damage. The is most likely related existence a sulfhydryl group drug.
Papaya is a fruit of great economic importance worldwide, but still presents high rate postharvest losses.Among the different reasons explaining this phenomenom, intensive labor and inappropriate storage conditions are main ones.Carnauba wax nanoemulsion (CWN) coating may be an alternative to problem, preserving quality.Therefore, experimental CWN was developed set three trials were conducted evaluate its performance on papaya fruits solo type.On first trial, applied at concentrations 4.5,...
Water stress is a major environmental factor affecting Citrus spp. and Rangpur lime drought-tolerant rootstock used to improve orange yield in rainfed orchards. Aiming comprehensive spatio-temporal evaluation of citrus responses drought, we combined morpho-physiological analyses with metabolic profiling roots leaves Valencia scions grafted onto lime, Swingle citrumelo or Sunki mandarin rootstocks under water deficit. Plant were evaluated during the initial phase reduction availability, when...
Essential oils and plant extracts can be safe alternatives for reducing post-harvest decay in foods compared to synthetic preservatives.Ginger oil (GO) ethanolic (GE) has been vitro studied.Antifungal activity associated with fruit coatings on papaya not exhaustively investigated until now.In this study, the antifungal of GOs GEs control Colletotrichum gloeosporioides was investigated.In results showed that GO higher GE, significantly mycelial growth.The measured minimum inhibitory...
The main goal of this research was to evaluate the postharvest quality during storage papaya wrapped with polyvinyl chloride containing silver.Fourier Transform Infrared Spectroscopy, scanning electron microscopy and atomic absorption spectroscopy were employed for film characterization.For experiments, unwrapped fruits compared individually ones in both conventional silver stored under two conditions (10 days at 15°C, 2 22°C simulate market conditions).The physicochemical analyzes,...
Edible coatings can be an alternative to extend shelf-life and preserve quality of fresh-cut fruits by forming a barrier that avoids physical microbiological damages.Such formed individual or multiple layers.The main aim this study consisted in the evaluation effect bilayer coating (carnauba wax chitosan) on apples.Chitosan carnauba were characterized, individually format, Attenuated Total Reflectance (ATR).The tests performed apple cv.Gala, sliced sanitized, five different treatments: (T1)...
