RESUMO

Proteomics is a field that has grown rapidly since its emergence in the mid-1990s, reaching many disciplines such as food technology. The application of proteomic techniques in the study of complex biological samples such as foods, specifically meat products, allows scientists to decipher the underlying cellular mechanisms behind different quality traits. Lately, much emphasis has been placed on the discovery of biomarkers that facilitate the prediction of biochemical transformations of the product and provide key information on parameters associated with traceability and food safety. This review study focuses on the contribution of proteomics in the improvement of processed meat products. Different techniques and strategies have recently been successfully carried out in the study of the proteome of these products that can help the development of foods with a higher sensory quality, while ensuring consumer safety through early detection of microbiological contamination and fraud. SIGNIFICANCE: The food industry and the academic world work together with the aim of responding to market demands, always seeking excellence. In particular, the meat industry has to face a series of challenges such as, achieving sensory attributes in accordance with the standards required by the consumer and maintaining a high level of safety and transparency, avoiding deliver adulterated and/or contaminated products. This review work exposes how the aforementioned challenges are attempted to be solved through proteomic technology, discussing the latest and most outstanding research in this regard, which undoubtedly contribute to improving the quality, in all the extension of the word, of meat products, providing relevant knowledge in the field of proteomic research.

RESUMO

3-Chloro-1,2-propanediol (3-MCPD) and its fatty acid esters (FE) are present as contaminants in different processed foods. Based on the available toxicological data the potential risk of 3-MCPD and its FE to human health was assessed by risk assessment authorities, including the European Food Safety Authority (EFSA). Considering the available data, EFSA concluded that 3-MCPD is a non-genotoxic compound exhibiting secondary carcinogenic effects in rodents. A tolerable daily intake of 2 µg/kg body weight and day was derived by EFSA for free and ester-bound 3-MCPD in 2018. However, there are still different pending issues that have remained unclear until now. Here, we summarize the current knowledge regarding 3-MCPD and its FE with a focus on pending issues regarding exposure assessment via biomarkers as well as the identification of (toxic) metabolites formed after exposure to FE of 3-MCPD and their modes of action.

RESUMO

Cultured meat is introduced as a valuable traditional meat equivalent. However, before marketable end products are available, several hurdles need to be overcome. Among others, these issues comprise obtaining an optimal nutritional profile and approaching the texture, the colour and the unique flavour and taste of conventional meat. Furthermore, the impact of processing on these matters is also still subject of future research. Moreover, more profound knowledge on food-safety aspects, like microbial contamination, prions, possible genetically engineered starting material, etc., and ways to reduce such risks will determine the future success of cultured meat products. Undoubtedly, correct terminology and adequate definitions also require further attention, as these form the starting point of legislative/regulatory aspects. This review provides a state-of-the-art overview on nutritional, technofunctional and sensorial properties, and food-safety and legislative/regulatory aspects on cultured meat production. Additionally, the various challenges and future steps of these aspects of cultured meat are highlighted.

RESUMO

Food security and food safety are two concepts related to food risks. The majority of studies regarding climate change and food risks are related to the security of food provision. The objective of this study was to review the current state of knowledge of the influence of climate change on food production and food safety. The literature search was carried out by specifying each area individually (crops, ranching, fishing, food safety, etc.), including the term "climate change" and other specific factors such as CO2, ozone, biotoxins, mortality, heat, etc.) The increase in carbon dioxide concentrations together with the increase in global temperatures theoretically produces greater yields in crops destined for human and animal consumption. However, the majority of studies have shown that crop yields are decreasing, due to the increase in the frequency of extreme weather events. Furthermore, these climate anomalies are irregularly distributed, with a greater impact on developing countries that have a lower capacity to address climate change. All of these factors result in greater uncertainty in terms of food provision and market speculation. An increase in average temperatures could lead to an increased risk of proliferation of micro-organisms that produce food-borne illnesses, such as salmonella and campylobacter. However, in developed countries with information systems that document the occurrence of these diseases over time, no clear trend has been determined, in part because of extensive food conservation controls.

RESUMO

Due to growing food safety issues, developing economic, rapid, and sensitive strategies for food spoilage monitoring has attracted significant attention. Here, a Bacillus subtilis spore-based biosensor is presented for rapid, highly sensitive, visual biogenic amines detection. The biosensor is fabricated through biogenic amines-induced pH increase which inhibits the electron transfer between Cu ion sites within CotA-laccase on the spore surface, leading to decrease in catalytic oxidation activity towards the chromogenic substrates. The developed system integrated with smartphone analysis realized the on-site monitoring of histamine with a detection range of 0.17-120 mg L-1, and a detection limit of 0.17 mg L-1 (3σ). Moreover, the color change induced by histamine is observable by the naked eye. The smart biosensor was successfully applied for food freshness evaluation in raw meat samples, showing several advantages, including eco-friendliness, low cost, and high stability, meeting the demands of on-site monitoring in the food safety field.

RESUMO

It was critically important to develop some sensitive, rapid, and specific imaging or detection methods for the virulent strain in food safety monitoring. In the study, a novel tetraphenyl mono-phenylboronic acid dye (TPE-PBA) with good aggregation-induced emission (AIE) features and high combining capacity towards bacteria was first synthesized. With TPE-PBA as a signal tag, a sandwich-type AIE probe-linked phage sorbent assay was developed for imaging and detecting virulent strains using Escherichia coli O157:H7 (E. coli O157:H7) as a representative. In the assay, phages for E. coli O157:H7 were firstly fixed on the bottom of a 96-well plate to specifically capture the strain, then the TPE-PBA signal tag was added and incubated with the captured strain to produce the phage/E. coli O157:H7/TPE-PBA complex. The complex could produce intensive AIE fluorescence being proportional to the amount of E. coli O157:H7 with a detection limit of 30 CFU mL-1 within 30 min. Simultaneously, the strain could be imaged in the plate with good anti-photobleaching and AIE effects. The results demonstrated the AIE-linked phage sorbent assay with a TPE-PBA signal tag could provide a suitable platform for rapid and specific detection and imaging of virulent strains. Therefore, it exhibited good application prospects in the on-site monitoring of food pathogens.

RESUMO

BACKGROUND: Acknowledged by the World Health Organisation (WHO), over 200 diseases ranging from mild to fatal are linked to the consumption of food products subjected to physical, chemical, or biological contamination. Nevertheless, conventional methods commonly used for the identification of health hazards in foodstuffs have problems coping with the sensitivity requirements imposed by latest-hour regulations in the field. Additionally, their use and availability is wildly limited by aspects such as instrument dimension, prohibitive costs, detection complexity and required operational knowledge. AIM OF REVIEW: This review provides an overview of recent efforts that have focused on the assesment of food contamination based on near infrared (NIR) photoluminescent sensors. Important endeavors that have targeted the precise detection of various inorganic and organic contaminants, including hydrogen sulfide, cyanide anions, mycotoxins, antibiotic residues, etc., are presented and relevant challenges that lie en route as stumbling blocks for such sensors to reach the next level of maturity and to become more available, are systematically discussed and enunciated. KEY SCIENTIFIC CONCEPTS OF REVIEW: Ingenious food contamination sensors that rely on conventional or up-conversion photoluminescence in the NIR region represent an emerging topic. To date, such sensors have been demonstrated as promising detection candidates, possessing important advantages such as: high efficiency, facile implementation, and convenient flexibility, thereby promising significant contributions to expand the current state of the art in food security.

RESUMO

Global climate change and the urgency to transform food crops require substantial breeding efforts to meet the food security challenges. Barley, an important cereal, has remained a preferential host of phytotoxic diseases caused by the Fusarium graminearum that not only severely reduces the crop yield but also compromises its food quality due to the accumulation of mycotoxins. To develop resistance against Fusarium infections, a better understanding of the host-pathogen interaction is inevitable and could be tracked through molecular insights. Here, we focused precisely on the potential gene targets that are exclusive to this devastating pathosystem and could be harnessed for fast breeding of barley. We also discuss the eco-friendly applications of nanobio hybrid and the CRISPR technology for barley protection. This review covers the critical information gaps within the subject and may be useful for the sustainable improvement of barley from the perspective of food and environmental safety concerns.

RESUMO

Food safety issues are directly related to people's quality of life, so there is a need to develop efficient and reliable food contaminants' detection devices to ensure the safety and quality of food. Electrochemical biosensors have the significant advantages of miniaturization, low cost, high sensitivity, high selectivity, rapid detection, and low detection limits using small amounts of samples, which are expected to enable on-site analysis of food products. In this paper, the latest electrochemical biosensors for the detection of biological contaminants, chemical contaminants, and genetically modified crops are reviewed based on the analytes of interest, electrode materials and modification methods, electrochemical methods, and detection limits. This review shows that electrochemical biosensors are poised to provide miniaturized, specific, selective, fast detection, and high-sensitivity sensor platforms for food safety.

RESUMO

Food pantries are an integral part of the food security safety net and were designed to distribute emergency food to alleviate short-term hunger. Given many rely on assistance long-term, food pantries may no longer meet the nutritional needs of the typical food pantry user. Less is known about the extent college students use campus food pantries and whether they seek ongoing food support. A comprehensive analysis of food pantry use, including reach, awareness, and student satisfaction was conducted using a cross-sectional campus survey, a student satisfaction survey, and observational data from pantry logs collected from August 2020 to May 2022. During the first year of operation, 20.6% of students were aware of the pantry, 3.1% of students were reached, and student satisfaction was high. About half of users visited once, while 15.4% visited 8 or more times during an academic year. On average, students that visited more had a larger span of use (6.5 months), visited more frequently (2 weeks between visits), and were more likely to be graduate students and older. While most students used the pantry in the short-term, chronic use of the pantry increased from year 1 to year 2. This suggests need may be growing and additional policies or programs are warranted to support students with chronic food needs.

RESUMO

Mycotoxins in food are hazardous for animal and human health, resulting in food waste and exacerbating the critical global food security situation. In addition, they affect commerce, particularly the incomes of rural farmers. The grave consequences of these contaminants require a comprehensive strategy for their elimination to preserve consumer safety and regulatory compliance. Therefore, developing a policy framework and control strategy for these contaminants is essential to improve food safety. In this context, sensing approaches based on metal-organic frameworks (MOF) offer a unique tool for the quick and effective detection of pathogenic microorganisms, heavy metals, prohibited food additives, persistent organic pollutants (POPs), toxins, veterinary medications, and pesticide residues. This review focuses on the rapid screening of MOF-based sensors to examine food safety by describing the main features and characteristics of MOF-based nanocomposites. In addition, the main prospects of MOF-based sensors are highlighted in this paper. MOF-based sensing approaches can be advantageous for assessing food safety owing to their mobility, affordability, dependability, sensitivity, and stability. We believe this report will assist readers in comprehending the impacts of food jeopardy exposure, the implications on health, and the usage of metal-organic frameworks for detecting and sensing nourishment risks.

RESUMO

Rice-based products exported from China to Europe have repeatedly encountered technical trade barriers. Using panel data from 24 states of the European Union during 2001-2017, this study builds a theoretical model to investigate the impact of implementation, intensity and structure of the Rapid Alert System for Food and Feed (RASFF) on China-EU rice-based product trade. The study found that RASFF has a serious inhibitory effect on the trade of traditional rice-based products because of detecting GM ingredients, showing an obvious lag effect, diffusion effect and structure effect. The negative effect occurs in entry process, and the inhibitory effect of border rejection and information notifications results in time lag, but the marginal effect of alerts for market links is insignificant. Moreover, the positive information disclosure effect of technical barriers implemented by individual members is much smaller than the negative diffusion effect. Finally, countermeasures and suggestions are proposed, including the source supervision of the test, the supervision of GM variety approval and GM seed production, the establishment of an early-warning and rapid-response mechanism to technical barriers of agricultural products, and food enterprise information.

RESUMO

Whether the quality of agricultural products is safe or not is related to issues of food safety and low carbon production in agriculture. Based on evolutionary game theory, this paper establishes a game model among government, farmers and consumers and analyzes the dynamic evolutionary process and evolutionary stable strategies of the major stakeholders. The results show that: (i) government subsidy coefficient, farmers' penalty coefficient for not producing, consumer trust coefficient and willingness to pay carbon labelled agricultural products premium are positively related to farmers' adoption of low-carbon production behaviour, and fraud penalty coefficient and farmers' cost of adopting low-carbon production technology are negatively related; (ii) farmers' sensitivity to government regulation policies is: fraud penalty coefficient = farmers' cost of adopting low-carbon production technology > government subsidy The sensitivity of farmers to government regulation policies is: fraud penalty coefficient = cost of low-carbon production technology > government subsidy > penalty coefficient for non-production, and the sensitivity of farmers to direct market stimulation is: consumer trust coefficient > coefficient of willingness to pay premium for carbon labelled agricultural products, and the additional benefit coefficient has no significant effect on farmers' decision-making; (iii) In the early stage, the source control of food safety mainly depends on the government's policy intervention. In the later stage, the establishment of carbon label agricultural products market incentive mechanism can achieve long-term stable and effective source control of food safety.

RESUMO

The increasing trend in ensuring safe and quality foods necessitates the monitoring of food products throughout the food supply chain. Food packaging is an indispensable process as it provides various functions such as containment, protection, convenience, and communication. The development of innovative packaging systems is required to ensure foods are microbiologically, chemically, and physically safe for consumption. In recent years, smart food packaging technologies namely intelligent and active packaging methods have become popular in the food packaging industry. However, in many cases, these smart packaging systems have not been adopted for large commercial-scale production. Development of rapid, sensitive, portable, user-friendly, and cost-effective food safety and quality analytical devices are required to meet both consumer and regulatory demands. Microfluidic technology has become a powerful tool as an alternative method to conventional laboratory-based analytical systems. The applications of microfluidic techniques in monitoring the safety and quality of a packaged food product are promising and rapidly advancing. Several studies have exhibited the development of microfluidic devices for smart food packaging such as time-temperature indicators, critical temperature indicators, food microorganism sensors, food quality detectors, and active food packaging. The future of food packaging lies in smart packaging technology which can function more than just protection and containment. This review focuses on the basic concepts of microfluidic technology and its application on intelligent and active packaging of food products and crystal ball gazing the future perspectives of this technology in food industry.

RESUMO

Dark kitchens are restaurants with no storefronts, no direct customer interaction and delivery-only commercial kitchens that rent out shared or private kitchen spaces to food businesses. The objective of this study is to determine consumers' knowledge about dark kitchens and the factors that influence willingness to pay and intention to purchase meals in this restaurant model. It were surveyed 623 Brazilian consumers. First, consumers' knowledge of the term dark kitchen was determined using specific questions. Then, consumers were presented with the actual meaning of dark kitchens and were asked about their intention to use this restaurant model. To this end, participants were presented with 25 indicators to assess the following constructs: willingness to pay and purchase intention, trust in health authorities, trust in food delivery app, perceived food safety, quality control, consumer experience, and solidarity with the foodservice sector. Overall, 73.4 % of participants reported having heard of the term dark kitchen. Using a descending hierarchical classification, four classes of definitions were found. The factor solidarity with the foodservice sector (ß = 0.440; p < 0.001) had the greatest positive influence on willingness to pay and purchase intention, followed by perceived food safety (ß = 0.273; p < 0.001); quality control (ß = 0.125; p = 0.003); consumer experience (ß = 0.110; p = 0.002) and trust in health authorities (ß = 0.059; p = 0.047). Even if consumers cannot accurately describe what a dark kitchen is, there is a positive intention to purchase food produced in this kitchen model. It is important to develop strategies to promote and improve dark kitchen models. Finally, it is suggested that health authorities and app operators pay more attention to improving food safety in these establishments, as consumers have low risk perception about them.

RESUMO

Contamination of agricultural products and foods by aflatoxin B1 (AFB1) is becoming a serious global problem, and the presence of AFB1 in edible oil is frequent and has become inevitable, especially in underdeveloped countries and regions. As AFB1 results from a possible degradation of aflatoxins and the interaction of the resulting toxic compound with food components, it could cause chronic disease or severe cancers, increasing morbidity and mortality. Therefore, rapid and reliable detection methods are essential for checking AFB1 occurrence in foodstuffs to ensure food safety. Recently, new biosensor technologies have become a research hotspot due to their characteristics of speed and accuracy. This review describes various technologies such as chromatographic and spectroscopic techniques, ELISA techniques, and biosensing techniques, along with their advantages and weaknesses, for AFB1 control in edible oil and provides new insight into AFB1 detection for future work. Although compared with other technologies, biosensor technology involves the cross integration of multiple technologies, such as spectral technology and new nano materials, and has great potential, some challenges regarding their stability, cost, etc., need further studies.
