文摘Herein,a reusable and portable surface-enhanced Raman spectroscopy(SERS)sandpaper was successfully synthesized for the sensitive detection of S-fenvalerate in foods.Commercial sandpapers were decorated with Ag@SiO2@Au nanoarrays via a liquid-liquid interface self-assembly method.The capacity of sandpaper to float directly on the cyclohexane-water interface allows nanoarrays to be formed directly on it,thereby minimizing stacking issues typically associated with nanoarray assemblies and significantly enhancing the sensitivity of S-fenvalerate detection.Moreover,the SERS sandpaper was reusable and portable due to its strong adhesion of the nanoarrays.Under optimized testing conditions,the developed SERS sandpaper method was capable of detecting S-fenvalerate,demonstrating a strong linear response within a concentration range of 10^(–7)–10^(3)μmol/L,with a limit of detection of 1.92×10^(−8)μmol/L.The analysis of spiked food samples containing S-fenvalerate using the developed SERS sandpaper afforded excellent recoveries(92.2%−109.7%).Additionally,the SERS sandpaper was successfully applied to quantify S-fenvalerate in real food samples,with results consistent with analyses conducted using gas chromatography.
文摘Nanofertilizers represent a breakthrough in sustainable agriculture,offering innovative solutions to improve nutrient efficiency,crop productivity,and environmental resilience.Engineered at the nanoscale,these fertilizers possess unique physicochemical properties,such as increased surface area,targeted delivery,and controlled release,which enhance nutrient uptake while reducing losses associated with conventional fertilizers.This review examines the evolving role of nanofertilizers in sustainable agricultural systems,exploring technological innovations,benefits,limitations,and potential risks.It aims to provide a comprehensive overview of their significance in advancing food security and environmental sustainability,while highlighting critical areas for future research and policy development.In particular,nanofertilizers show strong potential in improving food quality and safety by enhancing crop nutritional content,reducing pesticide residues,and boosting plant resistance to environmental stressors.Their roles in biofortification of staple crops such as wheat,rice,and maize could play a crucial part in addressing widespread micronutrient deficiencies globally.Furthermore,integrating nanofertilizers with precision agriculture technologies,including GPS mapping,remote sensing,and smart sensors,could enable site-specific nutrient management,optimizing fertilizer use and reducing environmental impact.However,concerns remain regarding their long-term effects on soil health,water systems,human health,and non-target organisms.Limited regulatory frameworks and high production costs also pose significant barriers to widespread adoption.This review underscores the need for interdisciplinary collaboration,green synthesis approaches,and ecosystem-level studies to ensure the safe and effective use of nanofertilizers.Ultimately,nanofertilizers offer transformative potential to support sustainable food systems and meet the growing demands of the global population.

文摘The breakthrough in super hybrid rice yield has significantly contributed to China’s and global food security.However,the inherent conflict between high productivity and environmentally sustainable agriculture poses substantial challenges.Issues such as water scarcity,energy crises,escalating greenhouse gas emissions,and diminishing farm profitability threaten longterm agricultural sustainability.In response,we applied a holistic food–carbon–nitrogen–water–energy–profit (FCNWEP)nexus framework to comprehensively assess the sustainability of distinct crop management strategies across three subsites in Central China.Field experiments were conducted in Hubei and Hunan provinces from 2017 to 2021 using a widely adopted elite super hybrid rice cultivar (Y-liangyou 900).Four crop management treatments were implemented:a control(CK,0 kg N ha^(-1)),conventional crop management (CCM,210–250 kg N ha^(-1),7:3 basal:mid-tiller fertilizer ratio),and two integrated crop management (ICM) treatments (ICM1,180–210 kg N ha^(-1),5:2:3 basal:mid-tiller:panicle initiation fertilizer ratio;ICM2,240–270 kg N ha^(-1),5:2:2:1 basal:mid-tiller:panicle initiation:flowering fertilizer ratio).Variables assessed included grain yield,carbon footprint,nitrogen footprint,water footprint,energy footprint,nitrogen use efficiency,and economic benefits.Our results showed significant yield variations,with ICM2 consistently outperforming CCM and ICM1across all three sites.In Jingzhou,Suizhou,and Changsha,ICM2’s grain yield was 30.2,24.7,and 13.3%higher than CCM,respectively.Net profits under ICM2 exceeded those of CCM and ICM1 by 31.8 and 115.2%in Jingzhou,32.2 and 109.9%in Suizhou,and 15.4 and 34.0%in Changsha,respectively.Integrated crop management,particularly ICM2,demonstrated improved nitrogen and energy use efficiency,leading to reduced carbon,nitrogen,water,and energy footprints.Overall,composite sustainability scores derived from the FCNWEP framework indicated that both ICM2 and ICM1 exhibited higher sustainability levels compared to CCM.This study provides valuable insights into practical management methodologies and offers recommendations for enhancing agricultural sustainability.

文摘A dietary transition from refined to whole grains would optimize grain processing,reduce food loss and emissions,and increase food nutritional contents.The results of systematical analysis and calculations in our study show that the average processing loss rate of grains including rice,wheat,and maize is approximately 4.1%in China due to the refinement,equivalent to an annual loss of around 13.3 Mt of grains.Furthermore,the refining process significantly reduces the nutritional contents of rice(51.6%),wheat flour(55.4%),and corn products(80.4%)mainly resulting from the removal of dietary fiber,minerals,and vitamins in refined grains.Replacing refined grains with whole grains in diets would lower agricultural carbon emissions by 2.7%,reducing agricultural water use by 4.3%,and saving arable land by 1,972,607 ha.Total environmental footprint could be reduced by 35%to 79%under three proposed scenarios.These findings indicate that shifting toward whole grain-based diets by Chinese consumers could reduce food losses,enhance human health,and improve environmental sustainability.This approach offers a promising strategy for transitioning towards more resilient and sustainable agri-food systems,benefiting human and planetary health.

文摘This study investigates the potential of starch extracted from underutilized agro-industrial resources as non-food-competing raw materials for the development of flexible bioplastics for food packaging applications.Starch was extracted from three biomass sources:rubber cassava(Manihot glaziovii),banana stem,and banana peel from Ambonese banana(Musa acuminata L.).Rubber cassava starch(SRC)exhibited the highest starch yield(50.68±0.28%),significantly surpassing banana stem(SBS,14.20±0.25%)and banana peel(SBP,3.07±0.15%).The amylose contents of SRC,SBS,and SBP were 28.18%,52.80%,and 56.57%,respectively,while their amylopectin contents were 71.83%,47.20%,and 43.43%.FTIR spectra confirmed the absence of cyanogenic groups in SRC,indicating its safety for packaging applications.XRD analysis revealed that PSRC films were predominantly amorphous,while PSBS and PSBP showed higher crystallinity.The enhancement of mechanical properties,specifically PSBS,showed the highest tensile strength at 16.04±0.56 MPa,whereas PSRC demonstrated the highest elongation at break at 23.57±0.40%,which could be attributed to the inherent characteristics of the starch sources.Additionally,PSRC film exhibited the highest transparency at 60.2%,the greatest water solubility at 34.92%,and the lowest water contact angle at 41.58○,confirming its more hydrophilic nature compared to other films.This work highlights the potential of low-cost,sustainable,and non-food agro-industrial starch sources as promising candidates for the development of flexible,eco-friendly bioplastics.

文摘In order to ensure food safety,controlling foodborne pathogen contamination is of utmost importance.Growing apprehensions regarding the safety of synthetic antimicrobials,due to their adverse health effects,have prompted a search for alternative options.Plant natural products(PNPs)with antimicrobial activity are being explored as a viable alternative.Among the various antimicrobial natural products studied,plant essential oils,plant flavonoids,plant polyphenols,plant polysaccharides,and plant antimicrobial peptides have been identified as potential candidates.PNPs demonstrate a diverse array of antimicrobial mechanisms,encompassing cell wall and membrane damage,interference with genetic replication,disruption of energy metabolism,and induction of oxidative stress at the single-cell level,as well as inhibition of biofilm formation and quorum sensing at the population level.Certain PNPs have been harnessed as natural antimicrobial agents for the food preservation.The utilization of encapsulation technology proves to be an effective strategy in protecting PNPs,thereby ensuring good antimicrobial efficacy,enhanced dispersibility,and controlled release within food products.The utilization of nanoemulsions,nanoliposomes,edible packaging,electrospun nanofibers,and microcapsules formed by encapsulation has enriched the ways in which PNPs can be applied in food preservation.Although PNPs have great potential in food preservation,their widespread application in the food industry is currently constrained by factors such as production costs,safety concerns,and legal considerations.Chemical synthesis and biosynthesis pathways offer viable strategies for reducing the cost of producing PNPs,and ongoing efforts to assess safety and improve regulatory frameworks are likely to facilitate the broader adoption of PNPs in food preservation practices.This article provides an overview of the main types of PNPs with antimicrobial activity and their properties,focusing on their mechanisms of action.Additionally,it summarizes the use of PNPs in food preservation and discusses the characteristics and applications of different encapsulation technologies.Lastly,the paper briefly analyzes current limitations and proposes potential future trends for this field.
文摘Food safety,specifically in restaurants,is becoming a key public health priority because of the increased number of meals eaten outside the home.Foodborne illness prevention thus is a significant concern and a public health priority in the United Arab Emirates,particularly Dubai,because of the extensive tourism industry.The purpose of the study was to evaluate the effectiveness of using demonstrations in training sessions to improve food safety knowledge and practices amongst food handlers.A descriptive and quantitative approach has been applied to collect the quantifiable information related to the research study.This has been further analyzed using the correlation tests to gather the required data.On comparison of the pre-test scores between the intervention and the control group,the t-test analysis showed significant difference in the level of food safety knowledge between the two groups.Pre-test score for the control group was 78.33 and post-test score was 104.66.In the case of the intervention group,pre-test score was 91.37 and post-test score was 130.75.The scores of food handlers’food safety practice for control group:pre-treatment score was 470 and post-treatment score was 646.For intervention group:pre-test score was 723 and post-test score was 1,056.The study concluded that training with demonstration techniques is an effective way of improving compliance with food safety guidelines.It has been understood that training helps in improving the performance of the employees while reducing the foodborne diseases and maintaining hygiene in the food.The study recommends every restaurant needs to provide regular trainings to the employees so that the restaurants can maintain hygiene and food safety practices.
