RESUMO

Neurodegenerative diseases are comprise a prominent class of neurological diseases. Generally, neurodegenerative diseases cannot be cured, and the available treatments can only regulate the symptoms or delay the disease progression. Among the several factors which could clarify the possible pathogenesis of neurodegenerative diseases, next to aging as the main risk, the dietary related diseases are the most important. Vegetable oils, which are composed of triacyclglycerols as the main components and several other components in a trace amount, are the main part of our diet. This review aims to study the effect of refined or unrefined vegetable oil consumption as a preventive or aiding strategy to slow or halt the progression of neurodegenerative diseases. In the refining process, owing to the chemical materials or severe temperatures of the refining process, removal of the desirable minor components is sometimes unavoidable and thus a worrisome issue affecting physical and neurological health.

RESUMO

The aim of this study was to replace chicken breast by mycoprotein in nuggets and optimizing the sensory and technological properties. In the first step of the study, 14 formulations were prepared by mixture design to evaluate the impact of three binding agents (as independent variables): soy protein isolate, phosphate, and carrageenan on sensory properties. Then, the optimized formulation of mycoprotein nugget (with higher acceptability) was characterized and compared to chicken nugget (control) from texture, color, and physicochemical aspects. The texture attributes including hardness, springiness, cohesiveness, and chewiness of the optimized sample (1.37 kg, 0.70 mm, 0.56, and 0.53 kg.mm) had no significant difference (p > .05) compared to control. Based on the results, optimized sample had a lower lightness and yellowness (a*, b*, and L* were 3.06, 18.62, and 59.23, respectively) rather than the similar value of the control (2.20, 21.27, and 79.10, respectively), which indicated carrageenan did not lead to any significant impact (p > .05) on the color. Also, mycoprotein nugget showed 33% lower cooking loss in comparison to control. Moisture, protein, lipid, and ash in optimized sample were 57.9 ± 1.9, 24.1 ± 1.0, 13.2 ± 1.2, and 2.1 ± 0.5, respectively. Investigation on physicochemical properties shows an acceptable characterization in optimized sample in comparison to control. The results of this study present an opportunity to produce nonmeat nuggets with similar texture and acceptable sensory and technological characteristics by using mycoprotein as meat alternative. The production of mycoprotein is eco-friendly, not dependent on climate (flood and drought) and landscape limitation, which is an important aspect in meat alternatives in the near future.

RESUMO

The presence of melamine in food is one of the most significant threats to consumer health and food safety now confronting the communities. The goal of this systematic review and meta-analysis was to determine the melamine content of different food products available on the Iranian market. The pooled melamine concentration (95% confidence interval) on 484 samples of animal-based foodstuffs was as follows: 0.22 (0.08, 0.36 mg kg-1) for milk, 0.39 (0.25, 0.53 mg kg-1) for coffee mate, 1.45 (1.36, 1.54 mg kg-1) for dairy cream, 0.90 (0.50, 1.29 mg kg-1) for yoghurt, 1.25 (1.20, 1.29 mg kg-1) for cheese, 0.81 (-0.16, 1.78 mg kg-1) for hen eggs, 1.28 (1.25, 1.31 mg kg-1) for poultry meat, 0.58 (0.35, 0.80 mg kg-1) for chocolates, and 0.98 (0.18, 1.78 mg kg-1) for infant formula. Based on the results of health risk assessment study on toddlers under 2 years old who ingested infant formula (as a melamine-sensitive group), all groups of toddlers are at an acceptable level of non-carcinogenic risk (THQ ≤ 1). Toddlers were classified according to their ILCR (carcinogenic risk) levels due to infant formula consumption as follows: under 6 months (0.0000056), 6-12 months (0.0000077), 12-18 months (0.0000102), and 18-24 months (0.0000117). The melamine carcinogenicity in infant formula for children had an ILCR value of 0.000001-0.0001 in the investigation, which was considerable risk. According to the findings, Iranian food products (notably infant formula) should be analyzed for melamine contamination on a regular basis.

RESUMO

This study aimed to conduct on the concentration of nitrate/nitrite (mg kg-1) in vegetables and fruits with a special emphasize on the effect of climate condition. The highest concentration (mean and 95%CI) of nitrate/nitrite was determined in Rocket (4825.15; 3044.14-6606.16), Mizuna (3500; 2702.48-4297.52), and Bok choy (3407.40; 2841.39-3973.42) in vegetable group and in wolfberry (2395.83; 1611.89-3179.77), Jack fruit (237.8; 202.88-272.71) and Cantaloupe (220.32; -224.53 to 665.19) in fruits group. Brazil (2816.77), Estonia (2133.76), Republic of China, Taiwan (2118.28) were the nations with the highest average concentration of nitrate/nitrite in all samples taken from these nations across the globe. Furthermore, Chinese fruits contain the highest concentrations of nitrates/nitrites of other countries (500.57; 416.74-584.41). Nitrate is present in greater quantities in fruits (44.02; 42.12-45.93) and vegetables (438.31; 422.51-454.11) than nitrite; however, the quantity of nitrite has a relatively similar content in both. Our findings revealed that increase in humidity (> 60%), annual rainfall (> 1500 mm), average temperature (> 10 °C) and application of fertilizers lead to significant increase in accumulation of nitrate/nitrite composition of vegetables and fruits (p < 0.05). According to the results of rating countries using the Food Security Index (GFSI), countries with high scores-like Poland and Portugal, which have GFSI scores of 75.5 and 78.7 and average contamination levels of 8.26 and 11.08, respectively-have a trend of average nitrate/nitrite levels of fruit and vegetable products that is significantly decreasing (p = 0.00). Although GFSI levels and other environmental variables can influence nitrate/nitrite levels, fertilizer usage (kg ha-1) is one of the most significant controllable and impactful factors in contaminants residue, which should be manage. The result of our study, will serve as a basis to estimate the dietary exposure to nitrates and nitrites from fruits and vegetables among populations around the world based on climatology and monitor the related health outcomes.

RESUMO

Malachite green (MG), an antibiotic with antifungal activity, is illegally used in aquaculture. Given that this chemical is teratogenic and mutagenic, abstinence from intake seems to be a need for public safety. The goal of this systematic review and meta-analysis was to determine the global contamination of fishes by MG and its reduced metabolite, leucomalachite green (LMG), in a number of marine and farmed fish species. For literature published prior to January 2022, several databases (Web of Science, PubMed, and Scopus) were investigated. In total, 20 publications (10 countries, 724 samples) achieved the criteria for inclusion. The overall average MG and LMG concentrations were 0.48 (95% CI: 0.47, 0.49 µg kg-1) and 0.59 (95% CI: 0.39, 0.79 µg/kg-1), respectively. Eel (M. albus) 15.50 (95% CI: (14.39, 45.39 µg kg-1) and eel (A. anguilla) 4.46 (95% CI: 1.23, 7.69 µg kg-1) had the greatest contamination of MG and LMG, according to the effect size, respectively. Warm-water fish had a concentration of 2.591 (95% CI: 2.25, 2.93 µg kg-1) while cold-water fish had a concentration of 1.55 (95% CI: 0.25, 2.84 µg kg-1). Fish containing medium-fat level of 1.86 (95% CI: 1.27, 2.44 µg kg-1) and high-fat content of 1.10 (95% CI: 0.93, 1.26 µg kg-1) had accumulate MG and LMG in their tissues, respectively. As a result, total MG observed in countries including China, Iran, and the Netherlands was higher than authorized (2 µg kg-1). The toxicity of MG and LMG demands more monitoring, especially in countries where these chemicals' residues are significant.

RESUMO

Iran is recognized as one of the top olive producers globally, and it forms an integral part of the countries agriculture, particularly in Zanjan province. This study measured Hg, As, Pb, Cd, and Zn concentrations and evaluated probabilistic health risk in olive products. Results showed that Zn had the highest concentration (traditional and industrial table olive, Parvardeh, and olive oil: 4.912 ± 3.957 and 9.181 ± 6.385; 16.139 ± 6.986 and 18.330 ± 8.700; 41.385 ± 7.480 and 46.043 ± 15.773 µg g-1, respectively) compared to other potentially toxic elements (PTEs). Additionally, Cd in table olive (traditional: 0.137 ± 199 and industrial: 0.059 ± 0.041 µg g-1) and Parvardeh (traditional: 0.014 ± 0.009 and industrial: 0.019 ± 0.006 µg g-1), and As in olive oil (traditional: 0.025 ± 0.006 and industrial: 0.026 ± 0.009 µg g-1) had the lowest concentrations, respectively. As and Hg in table olive (0.224 ± 0.214 and 1.158 ± 0.974 µg g-1) and Hg in Parvardeh (0.210 ± 0.213 µg g-1) samples were significantly higher in traditional than industrial products (p < 0.05). Cd in Parvardeh (0.019 ± 0.006 µg g-1) and Zn in table olive (9.181 ± 6.385 µg g-1) samples were substantially more in industrial than traditional products (p < 0.05). Results suggest that industrially processed olive products are more likely to introduce higher levels of PTEs into the body. Nevertheless, based on the health risk assessment criteria, industrial products' hazard index (HI) values were lower than traditional types due to high Hg concentrations (HI = 0.01227 and 0.2708, respectively). Adults' total carcinogenic risk (TCR) in traditional olive products was higher than in industrial (sum TCR = 0.00016 and 0.00007, respectively). In conclusion, the results indicated that the consumption of olive products in the study area offered an increased non-carcinogenic and cancer risk to the population of this region owing to PTEs exposure, especially Hg.

RESUMO

Risk assessment of heavy metals is critical in controlling and preventing risks of foodborne diseases. Fish can be used as bioindicators for exposure to potential toxic elements (PTEs), which can represent potential risks for humans. The long Iranian coastline and three major fishery regions in the country, including the northern (Caspian Sea) and southern (Persian Gulf and Gulf of Oman) seas as well as inland waters and aquacultures (rivers, dams, wetlands and fish farms) have made Iran a large producer of fish. In the first step of the present study, data collection and report of PTEs in fish from the three fishery regions (2010-2022) were carried out. In the second step, health risks were assessed using Monte Carlo simulation in child and adult consumers. The average concentrations of Cd, Hg and Pb for the northern sea, southern sea, and inland waters and aquacultures were 0.273, 0.249, 1.077; 0.430, 0.423, 1.182; and 1.387, 0.232, 1.703 µg/g per dry weight, respectively. Based on the target hazard quotient results, Hg intake of Iranian children from all the three fishery regions was more than 1, which was alarming. In the adult age group, southern sea fish consumers were at risk of Hg adverse health effects. Moreover, Cd included the highest carcinogenic risk of toxic elements in fish from the three fishery regions of Iran. Estimation of THQ, HI, ILCR and EDI revealed that consumption of fish might induce health complexities for the consumers in Iran. Moreover, Iranians from northern and southern regions of the country consumed further seafood due to the availability of high seafood sources in these regions. Hence, various indices must be used for the risk assessment of general human health. Due to the high risks of carcinogenicity/non-carcinogenicity estimated in the risk assessment, consumption of fish by infants and pregnant women must critically be assessed.

RESUMO

Packaging plays a critical role in determining the quality, safety, and shelf-life of many food products. There have been several innovations in the development of more effective food packaging materials recently. Polymer nanofibers are finding increasing attention as additives in packaging materials because of their ability to control their pore size, surface energy, barrier properties, antimicrobial activity, and mechanical strength. Electrospinning is a widely used processing method for fabricating nanofibers from food grade polymers. This review describes recent advances in the development of electrospun nanofibers for application in active and smart packaging materials. Moreover, it highlights the impact of these nanofibers on the physicochemical properties of packaging materials, as well as the application of nanofiber-loaded packaging materials to foods, such as dairy, meat, fruit, and vegetable products.


Electrospinning is a flexible method for smart and active packaging fabrication.Nanofibers can improve mechanical, barrier, and optical properties of packaging.Electrospun fibers can control the release of functional agents to food products.Incorporation of additives in nanofibers makes respond to environmental changes.Application of nanofibers result in improved controlling of food properties.

RESUMO

Background: The contamination of food products by Listeria monocytogenes as a pathogen bacterium, threatening public health and raised a global concern for a long time. Dairy and meat products and ready-to-eat foods are recognized as the most common carriers for L. monocytogenes. Methods: The related reports of the prevalence of L. monocytogenes in dairy products in Middle East countries from 2009 to 2020 were screened through some of the international databases such as Science Direct, Web of Science, Scopus, PubMed, and Google Scholar. While a random effect model was applied to estimate pooled or overall prevalence, 95% confidence intervals (95%CI) were used. Results: Results showed severe heterogeneity (84.2%) in studies and estimated the overall prevalence of L. monocytogenes dairy food products from the Middle East region of 3.5% (CI: 2.2-5). The highest and lowest prevalence was associated with Jordan (17.6% CI: 9.8-26.9) and Iraq (1.6% CI: 0.3-3.7), respectively. Based on the type of product, the highest and lowest prevalence of L. monocytogenes was recognized for raw cow milk (5.8% CI: 2.7-9.7) and pasteurized cow milk (1.1% CI: 0-8), respectively. Conclusion: There is no justification for severe heterogeneity (I2) of subgroups as prevalence is heterogenic innately, but Jordan and row cow milk subgroups were found to have a considerable effect on overall pooled prevalence. Thus, they were the reason for prevalence changes.

RESUMO

Potentially toxic elements (PTEs) as non-degradable elements (especially carcinogenic types for humans such as lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As)) are widely distributed in the environment. They are one of the most concerned pollutants that can be absorbed and accumulated in the human body, primarily via contaminated water and foods. Acute or chronic poisoning of humans to PTEs can pose some serious risks for human health even at low concentrations. In this context, some methods are introduced to eliminate or reduce their concentration. While the biological treatment by bacterial strains, particularly probiotic bacteria, is considered as an effective method for reducing or eliminating of them. The consumption of probiotics as nonpathogenic microorganisms at regular and adequate dose offer some beneficial health impacts, it can also be applied to remove PTEs in both alive and non-alive states. This review aimed to provide an overview regarding the efficacy of different types of probiotic bacteria for PTEs removal from various environments such as food, water, in vitro, and in vivo conditions.

RESUMO

Dairy products contain high contents of nutrients that favor the growth and proliferation of spoilage and pathogenic microorganisms, contributing to high risk in terms of quality deterioration and food safety. It has been demonstrated that packaging could protect airy products after manufacturing and it is capable of extending the shelf-life of these products. Among various kinds of packaging, intelligent packaging can utilized as an effective instrument for preservation of dairy products and also informs users about the entire background of the product. This review will address the attempts made toward developing intelligent packaging for dairy products including indicators (time temperature, gas & integrity and freshness), data carriers (RFID, barcode) and sensors.

RESUMO

Essential oils, as extracted compounds from plants, are volatile and aromatic liquids which their unique aromatic compounds give each essential oil its distinctive essence. Fungi toxins can induce various adverse health effects like allergy, cancer, and immunosuppression. Moreover, fungal spoilage impacts pharmaceutical and food industries economic state. A drop in the utilization of synthetic compounds as food prophylaxis has occurred due to several factors such as hygiene agents' alerts and stricter legal regulations. Therefore, the applications of natural substances such as essential oils have increased in recent years. Oregano, cinnamon, thyme, rosemary, fennel, clove, palmarosa, and eucalyptus have been the highest employed essential oils against mycotoxigenic fungi and their mycotoxins in studies conducted in the past decade. Essential oils inhibit fungi growth and mycotoxin synthesis via diverse pathways including modified fungal growth rate and extended lag phase, disruption of cell permeability, disruption of the electron transport chain and manipulating gene expression patterns and metabolic processes. In the present review, we will investigate the implications and efficacy of essential oils in preventing the growth of mycotoxigenic fungi, eliminating mycotoxins and their mechanism of actions conducted in the last decade.HighlightsThe most investigated toxigenic genera are Aspergillus, Fusarium and Penicillium Spp.AB1, AG1, OTA and AB2 are the most frequently studied toxinsOregano, cinnamon and thyme are mostly exploited EOs on toxigenic fungi & mycotoxinsOregano, thyme & cinnamon are the most significant antifungals on toxigenic generaCinnamon, oregano & cinnamaldehyde are the fittest antimycotoxins on DON, OTA & AFB1.

RESUMO

BACKGROUND: Lead (Pb2+ ) is one of the most toxic heavy metals and can be found in various quantities in the environment. The five native probiotic bacteria and inulin were used to assess in vitro lead nitrate and lead acetate binding capacities, as well as removal potentials. RESULTS: The highest decrease in media pH was seen for samples containing a combination of Lactobacillus paracasei IRBC-M 10784, lead nitrate and inulin (5.30 ± 0.012). The presence of inulin in the environment accelerated decreases in the pH of all samples with no significance. In all groups, lead nitrate-containing samples included maximum pH decreases. From the highest to the lowest, the ability of lead removal was linked to Lactobacillus acidophilus PTCC-1932 (88.48%), Bifidobacterium bifidum BIA-7 (85.32%), Bifidobacterium lactis BIA-6 (85.24%), Lactobacillus rhamnosus IBRC-M 10782 (83.18%) and L. paracasei IRBC-M 10784 (80.66%). Most species included the highest decrease in lead nitrate. Fourier-transform infrared spectroscopy (FTIR) analysis demonstrated that various functional groups (hydroxyl, carboxylic, carbonyl, amino and amide binds) on the bacterial cell wall were involved in lead ion binding during incubation. Principal component analysis of the FTIR results showed differences with respect to treated groups and control groups. CONCLUSION: The results obtained in the present study reveal that the simultaneous use of native probiotics and inulin can be an effective and safe approach for removing various toxic substances, especially Pb. © 2021 Society of Chemical Industry.

RESUMO

Exposure to food toxins generate multiple adverse health effects. Heavy metals, antibiotics residue, mycotoxins, pesticides and some food additives are examples of the most important food toxins. The common mechanism of toxicity and carcinogenicity effects of food toxins is the generation of oxidative stress that leads to DNA damages. Moreover, based on epidemiologic evidence unhealthy eating habits and food toxicities are associated with cancers occurrence. Therefore, application of bioactive food additives as harmless or safe components in food industry is expensive. Nigella sativa L. is a broadly used herb-drug for various diseases all over the world and has been used as preservative and food additive. Based on various studies N. sativa has shown various pharmacological activities including therapeutic efficacy against different human diseases and antioxidant anti-inflammatory effects against environmental toxins. N. sativa decreases the adverse health effects induced by mentioned food toxins via modulating the action of antioxidant enzymes such as glutathione peroxidase (GPx), glutathione-S-transferase catalase and act as reactive oxygen species (ROS) scavengers in different organs. Besides, N. sativa and thymoquinone (TQ) have protective effects on food products through removal and inhibition of various toxic compounds. Therefore, in the present review we will describe all protective effects of N. sativa and its main constituents, TQ, against food induced toxicities.

RESUMO

Toxoplasmosis is an infection caused by Toxoplasma gondii, a widespread zoonotic protozoan which poses a great threat to human health and economic well-being worldwide. It is usually acquired by ingestion of water contaminated with oocysts from the feces of infected cats or by the ingestion of raw or undercooked foodstuff containing tissue cysts. The oocyst can contaminate irrigation water and fresh edible produce. It is estimated that approximately one-third of the human population worldwide harbor this parasite. Infection with T. gondii is an important cause of diseases of the central nervous system and the eye in immunocompromised and immunocompetent individuals. The purpose of this study was to evaluate the efficacy and applicability of thermal (heating, cooking, freezing and low temperature), non-thermal (high pressure processing, ionizing irradiation and curing) and chemical and biochemical (disinfection, essential oils and biochemical methods such as enzymes, nanoparticles, antibiotics and immune response) treatments for the inactivation, inhabitation or to kill T. gondii in foodstuff intended for public consumption and under experimental conditions.
