RESUMO

Food safety and quality assessment mechanisms are unmet needs that industries and countries have been continuously facing in recent years. Our study aimed at developing a platform using Machine Learning algorithms to analyze Mass Spectrometry data for classification of tomatoes on organic and non-organic. Tomato samples were analyzed using silica gel plates and direct-infusion electrospray-ionization mass spectrometry technique. Decision Tree algorithm was tailored for data analysis. This model achieved 92% accuracy, 94% sensitivity and 90% precision in determining to which group each fruit belonged. Potential biomarkers evidenced differences in treatment and production for each group.

RESUMO

A novel and low-cost framework for food traceability, composed by commercial and proprietary sensing devices, for the remote monitoring of air, water, soil parameters and herbicide contamination during the farming process, has been developed and verified in real crop environments. It offers an integrated approach to food traceability with embedded systems supervision, approaching the problem to testify the quality of the food product. Moreover, it fills the gap of missing low-cost systems for monitoring cropping environments and pesticides contamination, satisfying the wide interest of regulatory agencies and final customers for a sustainable farming. The novelty of the proposed monitoring framework lies in the realization and the adoption of a fully automated prototype for in situ glyphosate detection. This device consists of a custom-made and automated fluidic system which, leveraging on the Molecularly Imprinted Polymer (MIP) sensing technology, permits to detect unwanted glyphosate contamination. The custom electronic mainboard, called ElectroSense, exhibits both the potentiostatic read-out of the sensor and the fluidic control to accomplish continuous unattended measurements. The complementary monitored parameters from commercial sensing devices are: temperature, relative humidity, atmospheric pressure, volumetric water content, electrical conductivity of the soil, pH of the irrigation water, total Volatile Organic Compounds (VOCs) and equivalent CO2. The framework has been validated during the olive farming activity in an Italian company, proving its efficacy for food traceability. Finally, the system has been adopted in a different crop field where pesticides treatments are practiced. This has been done in order to prove its capability to perform first level detection of pesticide treatments. Good correlation results between chemical sensors signals and pesticides treatments are highlighted.

RESUMO

Bombyx mori (BM) is an economically important insect for silk production, and it is also farmed and used as food in different countries around the world. The present systematic review aims to assess the suitability of BM as an edible insect, retrieving data from scientific papers reporting microbiological, chemical, and allergenic hazards of silkworm consumed as either whole insects or insect derivatives. We considered all studies published in peer-reviewed journals in English, French, and Spanish languages. No time limits were imposed. We searched PUBMED, WEB of Science Core Collection, and EMBASE databases. The last literature search was carried out on May 5th, 2021. Data were collected in pre-defined tabular forms for the aforementioned hazards. In total, 65 records investigating the safety aspects were included after screening: 32 on microbiological hazards; 27 on chemical hazards; 16 on allergenic hazards. Concerning microbiological aspects, a high presence of Enterococcus in raw insects (5.00 % to 70.10 %) was reported through metagenomic analysis. Through non-metagenomic methods (classical and biomolecular microbiology techniques), Bacillus cereus and Pseudomonas fluorescens were the most commonly investigated and detected bacteria in the unprocessed insects, while B. cereus and Enterobacteriaceae were studied and reported in insect-based food. The foodborne pathogens Listeria monocytogenes and Salmonella spp. were never detected. Concerning toxicological aspects, three studies assessed the toxicity of BM powder in laboratory animals, but no negative effects were observed. Regarding heavy metal bioaccumulation in BM, evidence was reported for As, Cu, and, Zn. Allergic reactions following the ingestion of BM or derivative products are due to proteins that are widespread in arthropods. Furthermore, BM proteins can undergo possible cross-reactions with proteins of other insect species or crustaceans. However, heat treatments do not seem to reduce the allergenic potential of the silkworm proteins. The major limitation of the present review is that we could include only scientific literature published in Western languages, while the majority of relevant studies were conducted in Asian countries and part of them are published in Asian languages. In conclusion, scientific evidence regarding microbiological and chemical hazards of BM relevant for food safety is very limited. In the present work microbiological and chemical hazards relevant for food safety were identified in BM, however their presence do not impair the use as food but suggest the need for a risk assessment under specific conditions of production and use. Allergic reactions are possible in sensitive individuals following the ingestion of edible BM.

RESUMO

The important role of Lactiplantibacillus plantarum strains in improving the human mucosal and systemic immunity, preventing non-steroidal anti-provocative drug-induced reduction in T-regulatory cells, and as probiotic starter cultures in food processing has motivated in-depth molecular and genomic research of these strains. The current study, building on this research concept, reveals the importance of Lactiplantibacillus plantarum 13-3 as a potential probiotic and bacteriocin-producing strain that helps in improving the condition of the human digestive system and thus enhances the immunity of the living beings via various extracellular proteins and exopolysaccharides. We have assessed the stability and quality of the L. plantarum 13-3 genome through de novo assembly and annotation through FAST-QC and RAST, respectively. The probiotic-producing components, secondary metabolites, phage prediction sites, pathogenicity and carbohydrate-producing enzymes in the genome of L. plantarum 13-3 have also been analyzed computationally. This study reveals that L. plantarum 13-3 is nonpathogenic with 218 subsystems and 32,918 qualities and five classes of sugars with several important functions. Two phage hit sites have been identified in the strain. Cyclic lactone autoinducer, terpenes, T3PKS, and RiPP-like gene clusters have also been identified in the strain evidencing its role in food processing. Combined, the non-pathogenicity and the food-processing ability of this strain have rendered this strain industrially important. The subsystem and qualities characterization provides a starting point to investigate the strain's healthcare-related applications as well.

RESUMO

Plants influence epiphytic bacterial associations but Salmonella enterica colonizes crop plants commensally, raising the possibility of human foodborne illness, but the factors that mediate human pathogen-plant associations remain understudied. We evaluated whether any changes in leaf tissue and surface metabolomes with kale (Brassica oleracea Acephala group) development and in response to drought modulated Salmonella leaf association. Untargeted phytochemical profiling (including primary and secondary metabolites) of kale leaf tissue extracts and leaf surface washes revealed distinct metabolite profiles that shifted with plant development. Metabolomes of juvenile plants also diverged in response to drought stress, an effect not noted in mature kale. Restricted watering in juvenile plants led to up-accumulation of 45 compounds in leaf tissue and 21 in leaf wash and the appearance of several unique peaks, with concomitant increases in phytochemical measurements. The antioxidant capacity and total flavonoid content were higher in mature than juvenile, regularly watered plant leaf extracts. Drought also elicited flavonoids and glucosinolates in juvenile plants. In mature plants, drought did not induce further prominent changes. Regularly watered juvenile kale provided a favorable substrate for inoculated Salmonella but the ability to support Salmonella declined with age and with drought stress. Salmonella growth was impaired in mature or water-stressed plant washes compared to controls and positive correlations were detected between Salmonella counts on leaves and in leaf washes. Moreover, Salmonella counts were inversely correlated with total flavonoids and phenolics in kale tissues from juvenile plants and regularly watered plants. Future studies should assess how changes in primary and secondary metabolites on the kale plant surface can modulate the Salmonella association. Regulated water restriction could be a strategy in controlled agriculture, with the dual purpose of enhancing health beneficial quality and food safety, especially when harvested at the baby kale stage.

RESUMO

The human gut microbiome plays a crucial role in skeletal homeostasis. The synbiotic consortium or Defined Microbial Assemblage™ (DMA™) food product, SBD111, consisting of probiotic microbes and prebiotic fibers was designed to promote bone health based on its capacity to produce short chain fatty acids (SCFA), the presence of genes for vitamin K2 production, and its ability to degrade plant fibers. A 28-day repeated administration study was performed to evaluate the oral toxicity of SBD111 in female rats (age/weight at study start: 5-7 weeks/120-180 g) administered levels of 0, 2.0 x 1010, 9.8 x 1010, or 2.0 x 1011 colony forming units (CFU)/kg-bw. No mortality or morbidity occurred during the study. There were no significant differences in body weights, hematology, serum chemistry, coagulation, organ weights, or food consumption in the test groups compared to the controls. Liver weight to body weight ratios were signficantly decreased at 9.8 x 1010 CFU/kg-bw when compared to controls. No treatment related changes in motor activity, sensory stimuli, or grip strength were observed. Based on these findings, SBD111 administered to female rats has a no-observable adverse effect level (NOAEL) at the highest level tested of 2.0 x 1011 CFU/kg-bw.

RESUMO

The increasing demand for food production has necessitated the development of sensitive and reliable methods of analysis, which allow for the optimization of storage and distribution while ensuring food safety. Methods to quantify and monitor volatile and biogenic amines are key to minimizing the waste of high-protein foods and to enable the safe consumption of fresh products. Novel materials and device designs have allowed the development of portable and reliable sensors that make use of different transduction methods for amine detection and food quality monitoring. Herein, we review the past decade's advances in volatile amine sensors for food quality monitoring. First, the role of volatile and biogenic amines as a food-quality index is presented. Moreover, a comprehensive overview of the distinct amine gas sensors is provided according to the transduction method, operation strategies, and distinct materials (e.g., metal oxide semiconductors, conjugated polymers, carbon nanotubes, graphene and its derivatives, transition metal dichalcogenides, metal organic frameworks, MXenes, quantum dots, and dyes, among others) employed in each case. These include chemoresistive, fluorometric, colorimetric, and microgravimetric sensors. Emphasis is also given to sensor arrays that record the food quality fingerprints and wireless devices that operate as radiofrequency identification (RFID) tags. Finally, challenges and future opportunities on the development of new amine sensors are presented aiming to encourage further research and technological development of reliable, integrated, and remotely accessible devices for food-quality monitoring.

RESUMO

Objective: This study aims to identify all actors that hold some responsibility for ensuring food safety based on the complete food supply chain in the context of China's current circumstances. Methods: The study was conducted among citizens in Wuxi, Jiangsu, China. All citizens fully understood the purpose of the study and voluntarily agreed to participate. From December 10 to 14, 2020, a total of 398 valid samples were collected by the researchers using a structured questionnaire. Survey data were assessed using best-worst scaling and a mixed logit model from the perspective of citizen responsibility. Results: In descending order, responsibility for ensuring food safety goes from food producers and traders (including producers, distributors, and retailers) to the government, social organizations, news media, and finally to citizens. Food producers and traders are the actors who should take the greatest responsibility, whereas citizens bear the least responsibility. Conclusion: The responsibility of citizens in food safety co-governance should be recognized but it should not be arbitrarily extended.

RESUMO

Food safety issues are inextricably linked to people's lives and, in extreme cases, endanger public safety and social stability. People are becoming increasingly concerned about food safety issues in a modern society with high-quality economic development. People's incomes are increasing day by day as the economy continues to grow, and the tourism industry has grown by leaps and bounds. However, many problems arose, such as the issue of food safety in tourism. Tourism food safety issues affect not only the development of the food industry but also the development of tourism. Food safety oversight of tourist attractions has always been a relatively concerning issue in the country, and it is also something that the general public is concerned about. It can be said that food safety supervision of tourist attractions is the most important thing in food safety supervision. In this context, it becomes an important task to evaluate the safety of tourist food. This work proposes a multiscale convolutional neural network (AMCNN) combined with neural networks and attention layers to realize the safety and quality evaluation of tourist food. The algorithm uses the lightweight Xception network as a basic model and utilizes multiscale depth-separable convolution modules of different sizes for feature extraction and fusion to extract richer food safety feature information. Furthermore, the convolutional attention module (CBAM) is embedded on the basis of the multiscale convolutional neural network, which makes the network model focus more on discriminative features.

RESUMO

In recent years, a variety of conventional and novel food sanitation technologies have been developed, among which some may adversely affect the organoleptic properties and the nutrients of foods. The increasing demand for fresh-like foods has promoted efforts for developing innovative technologies. The detrimental effects of some technologies on the sensorial and nutritional values of foods could be overcome by using the hurdle technology that has become a promising approach. The interest in using chlorine dioxide for food sanitation has increased due to its many advantages over chlorine such as its powerful antimicrobial activity and less formation of harmful disinfection by-products. However, using chlorine dioxide to achieve a complete pathogen elimination from foods is still hard. In this context, chlorine dioxide has been combined with other technologies to enhance microbial food safety. This review, therefore, aims to present the application of chlorine dioxide-based hurdle technology through sequential or simultaneous treatments to control foodborne pathogens. The antimicrobial effects of chlorine dioxide combined with thermal and non-thermal physical, chemical, and biological technologies on various foodborne pathogens in a wide range of food commodities are critically reviewed.

RESUMO

This study aims to evaluate the importance and performance level of knowledge about sanitary management among foodservice employees in childcare centers that were registered at Center for Children's Food Service Management in Chungju city according to their work duration, type of childcare center, and number of enrolled children. The self-administered questionnaire was conducted to examine food safety attributes of sanitary management at 150 childcare centers without qualified dietitians registered at Center for Children's Food Service Management of Chungju city. The questionnaire consisted of 15 questions about perceived importance and performance regarding sanitation management (personal hygiene, ingredient control, temperature control of food, facility, equipment, and utensils sanitation) using IPA (importance-performance analysis). The results show that overall mean scores of the importance and performance of sanitary knowledge were 4.71 and 4.67 out of 5, respectively. 'Checking the center temperature at 75 °C for 1 min in the thickest part of meat (3 times or more check for each serving)' (p = 0.047) and 'Keeping preserved meals (at least 100 g of each menu) for 144 h. with -18 °C or less' (p < 0.001) show significantly lower scores of performance than those of importance. The results of importance and performance for sanitary management according to work duration of foodservice employees show that those who have worked more than 10 years had the highest scores of importance and performance for overall sanitary management among them. For the types of childcare centers, the overall performance scores of national/public employees for sanitary management were lower than those of private or home type (p < 0.001). Additionally, the result showed that the overall importance (p < 0.001) and performance scores (p < 0.001) of employees for sanitary management in centers with <50 children were higher than those in centers with ≥50 children. This result should provide more useful information to develop food safety programs for employees and sustainable foodservice management in childcare centers.

RESUMO

Carcasses of common pheasants (Phasianus colchicus) killed by hunters using shotguns are widely used or sold in the United Kingdom and elsewhere for human consumption. Almost all of the birds are shot using shotgun pellets composed principally of lead (Pb). Lead shotgun pellets often fragment on impact within the bodies of gamebirds, leaving small lead particles in the meat that are difficult for consumers to detect and remove and from which a greater proportion of lead is likely to be absorbed. Chronic exposure to even low levels of lead is associated with negative health effects in humans and especially in groups particularly vulnerable to the effects of lead, which include young children and pregnant women. Our study used a high-resolution computerised tomography X-ray scanner to locate, in three dimensions, metal fragments embedded within carcasses of eight pheasants sold for human consumption in the UK. Small radio-dense fragments (<2 mm diameter), assumed to be metallic lead, were present in all of the pheasant carcasses examined (mean number: 39 per carcass) and many were too small (<0.1 mm diameter) and too distant from the nearest large shotgun pellet for it to be practical for consumers to detect and remove them without discarding a large proportion of otherwise usable meat. Consumers of carcasses of pheasants killed using lead shotgun ammunition are likely to be exposed to elevated levels of dietary lead, even if careful food preparation is practiced to remove shotgun pellets and the most damaged tissue.

RESUMO

In recent years, foodborne diseases caused by pathogens have been increasing. Therefore, it is essential to control the growth and transmission of pathogens. Bacteriophages (phages) have the potential to play an important role in the biological prevention, control, and treatment of these foodborne diseases due to their favorable advantages. Phages not only effectively inhibit pathogenic bacteria and prolong the shelf life of food, but also possess the advantages of specificity and an absence of chemical residues. Currently, there are many cases of phage applications in agriculture, animal disease prevention and control, food safety, and the treatment of drug-resistant disease. In this review, we summarize the recent research progress on phages against foodborne pathogenic bacteria, including Escherichia coli, Salmonella, Campylobacter, Listeria monocytogenes, Shigella, Vibrio parahaemolyticus, and Staphylococcus aureus. We also discuss the main issues and their corresponding solutions in the application of phages in the food industry. In recent years, although researchers have discovered more phages with potential applications in the food industry, most researchers use these phages based on their host spectrum, and the application environment is mostly in the laboratory. Therefore, the practical application of these phages in different aspects of the food industry may be unsatisfactory and even have some negative effects. Thus, we suggest that before using these phages, it is necessary to identify their specific receptors. Using their specific receptors as the selection basis for their application and combining phages with other phages or phages with traditional antibacterial agents may further improve their safety and application efficiency. Collectively, this review provides a theoretical reference for the basic research and application of phages in the food industry.

RESUMO

Urbanisation and changing food habits in India have resulted in a shift in consumption from cereals to protein-based foods. Women play a major role in India in all activities related to food at household and therefore, the current paper reports the findings of the qualitative work conducted to understand women consumers' preference and perception towards meat and its attributes as a function of their awareness. The study collected the responses from 510 women residents of Metropolitan city of Bengaluru, India using questionnaires directly by face-to-face interviews and generated data on preference for fresh meat, purchase habits, value added meat products consumption, awareness about meat quality, and future expectations about meat sector. Findings from the current study indicate that, chicken is the most preferred meat (41.76%) while beef was least preferred (5.88%). The 40.59% of respondents preferred meat tenderness as an important eating quality followed by juiciness (37.06%) and flavor (12.94%). Consumers rated ritual slaughter, animal welfare and food safety as relevant issues in meat production, whereas regulations pertaining to meat production, processing of meat and food labelling were of minor significance. The study provide an insight into the significance of various consumer behaviour with respect to choice of meat, awareness on ritual slaughter, animal welfare and processing which is helpful in prioritizing future consumer research and policy decisions in India.

RESUMO

The COVID-19 pandemic affected the food supply chain, retailers, and consumers owing to infection awareness. This study evaluated the impacts COVID-19 on ASF retailers' businesses and consumers' livelihoods, as well as their knowledge toward the disease, attitudes, and food safety practices to prevent infections. The study includes a cross-sectional component that was conducted in urban/peri-urban (U/PU) and rural areas in Chiang Mai province. In another part of the study, a structured questionnaire was developed for animal source food (ASF) retailers and consumers, with three primary parts for data analysis: general information, COVID-19 impacts, and knowledge, attitudes, and practices (KAP) assessment. Data corresponding to three periods of interest (before the COVID-19 outbreak, during partial lockdown, and present) were gathered and analyzed. In this study, 155 retailers and 150 consumers participated, of which the majority of the respondents were female (70.3% and 82.7%, respectively) with average ages of 47.4 and 44.9 years, respectively. The most noticeable effect of COVID-19 was a decline in income for retailers and consumers. The KAP scores of consumers in both areas were not significantly different, whereas the retailer attitudes toward COVID-19 prevention and food safety practices scored more highly in rural areas than in U/PU. During the partial lockdown, food safety practices significantly improved relative to the time preceding the outbreak, and these practices have remained constant to the present day. The results revealed that gender, age group, business type, and type of ASF retailers were associated with the KAP of the retailers, whereas gender, age group, education, number of family members, and occupation were associated with the KAP of the consumers. Our findings provide in-depth information about the effects of COVID-19 on ASF retailers and consumers, as well as their KAP regarding the outbreak and food safety, which may serve as support in developing policies for improved health and food safety.

RESUMO

The development and application of cell-based biosensors (CBBs) provides a convenient strategy for rapid detection of target analytes. The CBBs had been widely applied in the fields of food safety, environment monitoring, and medicine diagnosis due to their advantages of short response time, easy operation, low toxicity, and portability. However, the CBBs based on two-dimensional (2D) cultured cells in-vitro suffer from a lower cell viability and isolated physiology, which had blocked the accurate evaluations of these biosensors. With the development of nanotechnology and three-dimensional (3D) printing technology, cells fixed in a 3D biosensor or a 3D microenvironment have shown great improvement in the sensitivity and detection authenticity than conventional CBBs. To promote the further development of CBBs, in this paper, we reviewed the related technologies used to construct 3D bionic cell chips including organic/inorganic agents and operating approaches suitable for constructing 3D cell cultural microenvironment. Then, the applications of 3D bionic cell chip based on microbial and mammalian cell biosensors in food safety field were discussed during recent ten years. Finally, the current challenges and further directions were summarized and prospected.

RESUMO

Nowadays, the increasing number of foodborne disease outbreaks around the globe has aroused the wide attention of the food industry and regulators. During food production, processing, storage, and transportation, microorganisms may grow and secrete toxins as well as other harmful substances. These kinds of food contamination from microbiological and chemical sources can seriously endanger human health. The traditional detection methods such as cell culture and colony counting cannot meet the requirements of rapid detection due to some intrinsic shortcomings, such as being time-consuming, laborious, and requiring expensive instrumentation or a central laboratory. In the past decade, efforts have been made to develop rapid, sensitive, and easy-to-use detection platforms for on-site food safety regulation. Herein, we review one type of promising biosensing platform that may revolutionize the current food surveillance approaches, the giant magnetoresistance (GMR) biosensors. Benefiting from the advances of nanotechnology, hundreds to thousands of GMR biosensors can be integrated into a fingernail-sized area, allowing the higher throughput screening of food samples at a lower cost. In addition, combined with on-chip microfluidic channels and filtration function, this type of GMR biosensing system can be fully automatic, and less operator training is required. Furthermore, the compact-sized GMR biosensor platforms could be further extended to related food contamination and the field screening of other pathogen targets.

RESUMO

Objective: Food safety risk management is an important cross-boundary issue from both theoretical and practical standpoints. Because food safety has the social attributes of public goods, public-public collaboration can be considered a particularly important mode of cross-boundary governance. The study aims to provide a theoretical basis for the Chinese government to promote public-public collaboration for food safety risk management by identifying key factors. Methods: Based on a review of literature across diverse fields, such as political science, sociology, and new public governance, this study discusses the essence, modes, and dilemma of public-public collaboration for food safety risk management using practical explorations in various countries as the main thread and taking into account the actual situation in China. Moreover, this study quantitatively analyzes the relationships between the dimensions and factors affecting public-public collaboration and identifies key dimensions and factors using the Decision-making Trial and Evaluation Laboratory-based Analytic Network Process (DANP). Results: Among the 20 factors in the calculation results of DANP, Lawmaking has the highest value of (f i +e i ) (7.022) and ranks sixth in terms of influence weight.
