The occurrence of pesticide residues in pome fruits and their implications for consumer health remain critical concerns in food safety. In this study, 222 pesticide residues were analysed in 155 samples of apples, pears, and quinces collected from Türkiye between October 2025 and March 2026 using liquid chromatography–tandem mass spectrometry (LC-MS/MS). Residues were detected in 76.4% of apples, 86% of pears, and 30% of quinces, with frequent multi-residue patterns and notable occurrences of non-approved compounds. Pear samples exhibited the highest contamination levels, with maximum residue level (MRL) exceedance rates reaching 30%, compared to 14.5% in apples and 2% in quinces. Quality assessment based on the index of quality for residues (IqR) indicated that 96% of quince samples were classified as excellent or good, demonstrating the most favourable profile among the evaluated commodities. Risk ranking analysis further indicated that acetamiprid was the only high-risk pesticide in apples, whereas residues in pears were predominantly medium risk, and all detected compounds in quinces fell within the low-risk category. Deterministic risk assessment indicated that chronic exposure remained well below levels of concern for both adults and children. Under combined pome fruit consumption, acetamiprid and spirodiclofen were identified as the main contributors to chronic hazard index (HIc), accounting for 33% and 13% of HIc, respectively. However, acute exposure exceeded the safety threshold (HQa > 1) in children for acetamiprid in both apples and pears. Probabilistic modelling confirmed right-skewed exposure distributions and highlighted increased risk under cumulative consumption scenarios. Full article

Cydia pomonella (Linnaeus, 1758) is considered one of the major pests affecting global pome fruit production due to its wide distribution, cryptic feeding habit, high economic impact, and continuous evolution of insecticide resistance. Historically, management of this species has relied on repeated pesticide applications, which have been associated with environmental impacts, occupational exposure, pesticide residues in food, and compromised sustainability of pesticide-dependent agricultural systems, reinforcing the relevance of integrated One Health approaches. This narrative review analyzed global management strategies for C. pomonella published between 2014 and 2024 and indexed in the Scopus, Web of Science, and SciELO databases. The reviewed studies demonstrate a gradual transition from predominantly chemical-based programs toward integrated strategies involving pheromone-based monitoring, mating disruption, biological control, and preventive plant biosecurity measures. Behavioral and biological approaches showed potential to reduce dependence on recurrent insecticide applications, particularly when associated with phytosanitary surveillance and integrated pest management programs. However, the effectiveness of these approaches remains influenced by insecticide resistance, climatic variability, and local ecological conditions. The evidence also suggests that the impacts of C. pomonella management are not limited to phytosanitary protection, involving interactions related to environmental sustainability, food safety, and human exposure to pesticides. Despite the relevance of the One Health approach, its operational incorporation into agricultural pest management remains limited, especially regarding the integration of research conducted under the One Health perspective. In this context, the sustainable management of Cydia pomonella requires integrated strategies capable of connecting phytosanitary surveillance, preventive plant biosecurity, and agricultural and ecological sustainability in order to ensure food security and population health.

The oil palm production chain generates coproducts whose sustainable valorization remains a challenge. This study tested the hypothesis that partial replacement of the conventional substrate with oil palm coproducts could maintain the productive performance of Zophobas atratus larvae and generate value-added biomass. Mesocarp fiber (MF), palm oil mill effluent (POME), and palm kernel cake (PKC) were characterized in terms of physicochemical composition, carotenoids, and antioxidant capacity and examined as partial substitutes for wheat bran in six diets for Z. atratus. PKC demonstrated higher levels of protein (15.27%), carbohydrates (65.68%), neutral detergent fiber (68.35%), acid detergent fiber (37.70%), and saturated fatty acids (83.06%) and greater antioxidant capacity associated with phenolic compounds. MF showed the highest carotenoid content (138.27 mg/100 g), and POME had the highest lipid content (17.69%). Diet containing 50% PKC-supplemented wheat bran promoted higher feed conversion efficiency (78.99%), lower feed conversion ratio (0.90%), and higher larval protein content (39.14%) and maintained performance similar to that of the control. Larvae fed on 50% MF exhibited carotenoid bioaccumulation, with >190% increase compared with the control. Although the coproducts demonstrate potential as substrates, mortality restricts their technical feasibility. Their use depends on an adequate protein/energy balance and the digestibility of the fibrous fraction for strategic supplementation. Full article

Organic acids are the core of fruit flavor quality and cell metabolism, but a comprehensive review of their metabolism and regulatory networks in fruit trees is still limited. Here, we systematically summarized the biosynthesis, degradation and transport of major organic acids in fruits of horticultural crops. We focused on the distribution and molecular regulation of organic acids in citrus, pome fruits, stone fruits, grapes and tropical–subtropical fruits, and emphasized the regulation of transcription factors, epigenetic modifications and environmental signals. We also evaluated the progress of various omics strategies for dissecting organic acid metabolism and identifying key regulatory genes. Finally, we discuss the current research gaps and propose future directions for multi-gene editing and molecular design breeding. This review provides a theoretical framework for improving fruit flavor quality and breeding excellent varieties. Full article

Species of Penicillium are among the most important fungal pathogens responsible for postharvest diseases of agricultural crops worldwide. This review provides an overview of five economically important Penicillium spp., namely P. expansum, P. digitatum, P. italicum, P. citrinum, and P. oxalicum. Emphasis is placed on P. expansum, P. digitatum, and P. italicum which are the main causal agents of blue mold and green mold rots in pome fruits and citrus, commodities that dominate global fresh produce trade and long-term storage. While studies on plant-pathogenic Penicillium are mainly focused on these hosts, this review highlights reports of infections in other crops across diverse geographic regions, highlighting the broader host range of these species. The main aspects highlighted include host specificity and diversity, production of mycotoxins and other secondary metabolites, current management and control strategies, and the potential influence of climate change on disease incidence and severity. Understanding the biology and epidemiology of plant-pathogenic Penicillium species is essential, as several species are both pathogens and producers of mycotoxins, leading to quality deterioration and nutrient depletion resulting in economic losses.

Angiogenesis is a spatially regulated hallmark of colorectal cancer (CRC) progression, yet current analytical frameworks fail to resolve how nutraceutical bioactive compounds interact with angiogenic signalling within the heterogeneous tumour microenvironment. This review advances a central hypothesis: that the spatial localisation of palm oil mill effluent (POME)-derived bioactive compounds within CRC tumour tissues is predictive of their functional anti-angiogenic activity. POME—the largest waste stream of palm oil processing—contains a chemically diverse array of bioactives, including tocotrienols, phenolics, carotenoids, and fatty acids, with reported antioxidant, anti-inflammatory, and anti-angiogenic properties. However, the existing evidence is predominantly derived from bulk in vitro analyses, limiting mechanistic conclusions about compound behaviour within spatially organised tumour architectures. To address this gap, we propose an integrated framework positioning mass spectrometry imaging (MSI)—across matrix-assisted laser desorption/ionisation (MALDI), desorption electrospray ionisation (DESI), and secondary ion mass spectrometry (SIMS) platforms—as the analytical bridge between compound localisation and angiogenic function. By enabling the label-free, spatially resolved co-localisation of POME-derived compounds with key angiogenic mediators, including VEGF, HIF-1α, and NF-κB, within intact CRC tissues, MSI provides a mechanistic platform that transcends the limitations of conventional molecular analyses. A four-component translational roadmap is outlined, encompassing POME bioactive profiling, spatial compound mapping, angiogenic co-localisation analysis, and functional validation. Critically, the existing evidence on oil palm-derived bioactives is appraised with respect to study quality, mechanistic depth, and translational limitations, identifying the most analytically tractable candidate compounds for spatial investigation. Collectively, this framework positions POME valorisation within a precision nutraceutical oncology paradigm, offering a spatially informed strategy for anti-angiogenic intervention in CRC while simultaneously addressing the environmental burden of palm oil processing waste.

Curvularins, a class of macrocyclic lactones, have cytotoxic, antimicrobial, and anti-inflammatory properties. Curvularin, a 12-membered macrolactone, was used as a scaffold to design and synthesize structurally modified analogues to investigate structure–activity relationships and improve biological efficacy. Three series of curvularin-based analogues, Cur-5H-OMe, Cur-4P-OMe, and Cur-OMe, were synthesized with the same core structure but different substituent sizes and positions. Nine representative derivatives were evaluated for anti-inflammatory, anticancer, antibacterial, and antifungal activities. In LPS-stimulated RAW 264.7 macrophages, most compounds inhibited nitric oxide (NO) production in a concentration-dependent manner but exhibited cytotoxicity at high concentrations. Cytotoxicity assays against HaCaT cells and human cancer cell lines (HCT116, HeLa, and A375) revealed limited selectivity toward cancer cells. Antimicrobial evaluation indicated selective activity against the Gram-positive bacteria, Staphylococcus aureus. Compound 23 exhibited superior antibacterial potency compared with kanamycin and notable antifungal activity against Candida albicans. This study provides a versatile synthetic platform and identifies key structural features of curvularin derivatives, demonstrating their potential as anti-inflammatory and antimicrobial lead compounds.

The potential withdrawal of glyphosate necessitates a comprehensive evaluation of alternative weed control strategies that balances human health safety with environmental concerns. This study applied a decision-support grid to compare the impacts of glyphosate-based reference strategies against chemical and non-chemical alternatives across four Belgian case studies: pome fruit orchards, grassland renewal, arable weed patches, and railways. The assessment integrated twelve risk indicators including human, environmental and biodiversity risk, and life cycle assessment for global warming potential (GWP) into a Final Scenario Score (FSS). The results indicated that only one alternative strategy, the chemical alternative in local weed patch control, achieved the FSS threshold (<0.75) required to justify substitution (FSS = 0.70). Chemical alternatives in other case studies frequently shifted burdens; for instance, bio-herbicides in railways increased risks to residents and aquatic organisms compared to the reference. Conversely, mechanical and thermal alternatives eliminated chemical toxicity but resulted in GWP increases up to 32 times higher than glyphosate-based practices. These findings demonstrate that chemical substitutes often maintain toxicity risks while non-chemical strategies trade them for increased climate impacts. Consequently, a ban on glyphosate is currently unsupported by the environmental performance of available alternatives in these temperate high-intensity systems. Sustainable progress requires a transition period where optimized conventional strategies remain available within integrated weed management, while innovations in electrification and precision technology are accelerated to resolve current trade-offs.

(1) Pome fruits (apples and pears) are among the most frequently consumed fruits in Europe and may contribute to dietary exposure to pesticide residues. Although residue levels generally comply with maximum residue limits (MRLs), even low concentrations may cumulatively contribute to chronic health risks under conditions of frequent and long-term consumption. This study aimed to quantitatively assess dietary exposure and the potential non-carcinogenic health risks associated with pesticide residues in apples and pears, using representative monitoring and consumption data. (2) The assessment was based on results of the Polish national official monitoring program for pesticide residues in food, specifically apples and pears sampled in 2022, as reported by the National Institute of Public Health (NIZP-PZH). These data were combined with age- and body weight-specific consumption scenarios derived from FAO/WHO GEMS/Food cluster diets and national Polish statistics. For the most frequently detected pesticides (captan, flonicamid, acetamiprid and fosetyl-Al in apples; captan and acetamiprid in pears), the mean and 95th percentile concentrations were used to estimate the estimated daily intake (EDI). Non-carcinogenic risk was characterized using the hazard quotient (HQ = EDI/ADI) and the cumulative Hazard Index (HI). The hazard quotient (HQ) was calculated as the ratio of estimated daily intake to the acceptable daily intake (HQ = EDI/ADI), while the Hazard Index (HI) was defined as the sum of individual HQ values for pesticides detected in a given commodity and exposure scenario (HI = ΣHQ). Calculations were performed separately for children and adults under several dietary scenarios (Polish general population, German child, German general population, GEMS/Food G08). (3) For all pesticides and exposure scenarios, the HQ values were well below 1, indicating no exceedance of the acceptable daily intake (ADI). The highest chronic exposure was observed for apples in children (German child scenario), with the HQ values for captan, flonicamid and acetamiprid in the approximate range of 0.01–0.05, while the HI remained < 0.1 even under high-consumption conditions. In adults (Polish and German general populations, GEMS/Food G08), HQ values were approximately one order of magnitude lower than in children, and the cumulative HI values for both apples and pears were far below 1. The contribution of pears to total exposure was limited, reflecting lower consumption and fewer active substances detected. (4) This quantitative risk assessment, based on Polish monitoring data from 2022, indicates that under current residue levels and consumption patterns, chronic dietary exposure to pesticide residues from apples and pears does not pose a relevant non-carcinogenic health concern for either children or adults. Nevertheless, children consistently showed higher relative exposure than adults, underscoring the importance of age-stratified risk assessment and continued monitoring of residues in commonly consumed fruits. The findings support existing regulatory frameworks while justifying sustained, targeted surveillance of key active substances in pome fruits as part of public health prevention strategies.

Traditionally focused on rent collection and facility upkeep, property management (PM) is evolving into a more strategic function that contributes to asset value and sustainability objectives. Digital tools and platforms, broadly referred to as Property Technology (“PropTech”), have emerged as key enablers to handle the growing scale and complexity of PM operations. However, despite the proliferation of PropTech solutions, concerns persist that the PropTech “supply” is not fully aligned with the “demand,” namely, the practical needs of PM professionals. Through a systematic search of the sector’s activities, an analysis of existing digital solutions for PM, an analysis of four PropTech solutions, and a survey among industry professionals, this paper aims to explore the mismatch between the demand and supply of digital tools for property management. The findings identify a divergence between the digital solutions developed by PropTech firms and the actual needs, practices, and levels of digital maturity within PM in three main areas of mismatch, namely: perception vs. engagement, tools offered vs. activities performed, and strategic vision vs. operational culture. This categorization highlights both the opportunities and challenges in the ongoing digital transformation of the real estate sector. Full article

Temperate fruits, mostly comprising pome, stone fruits, and berries with immense nutritional benefits and a storehouse of various therapeutic phytochemicals, are prone to several physiological disorders immediately after harvest. The etiology, symptom progression, and decay incidence are influenced by pre-harvest and post-harvest factors, causing significant economic loss with respect to both the energy and economics invested. Respiratory end products, ethylene generation, and enzymatic activities interact to influence the metabolic response and associated biochemical variation. Advanced packaging technologies have emerged as innovative solutions to curtail these post-harvest problems. The design and development of novel packaging technologies need to critically understand the respiratory behavior of the fruits and their associated metabolic functions. A desirable polymer or packaging technology should exhibit enhanced barriers to the gases while providing adequate support to the fruit matrix. In addition, it should also fulfill the role of environmental sustainability and the circular economy. The outcome of this review will highlight the importance of proper post-harvest procedure, appropriate pretreatment, packaging matrix selection, and the storage conditions for effective and enhanced shelf-life storage. Therefore, this review was structured in two phases; the first phase discusses the biochemical understanding of the fruit during storage and transit in response to stress factors. The next phase highlights the various packaging interventions (polymers, biodegradable films, edible coatings, smart packaging, nano-packaging) taken to address these issues, with a key focus on shelf-life enhancement. Further, the key limitations of each technology are appraised. Full article

This study analyzes the valorization of oil palm biomass residues within the framework of industrial symbiosis (IS), emphasizing their role in circular economy strategies and sustainable industrial development. Through a systematic literature review and snowball sampling, 156 articles indexed in Scopus and Web of Science were examined, classifying evidence by country, type of residue, derived products, economic sector (ISIC Rev. 4), and technological approach. The results show a strong geographical concentration of IS experiences in Asia, particularly Malaysia, Indonesia, and Thailand, where residues such as empty fruit bunches (EFB), palm kernel shells (PKS), oil palm mesocarp fibers, palm oil mill effluent (POME), and oil palm trunks (OPT) are integrated into processes for bioenergy, biochemicals, composite materials, construction products, biochar, and bioplastics. In contrast, applications in Latin America and Africa remain incipient, with high potential but limited industrial implementation due to infrastructural and regulatory gaps. Technological trends point toward thermo-chemical and biological conversion routes (pyrolysis, gasification, hydrothermal carbonization, anaerobic digestion), development of advanced materials and catalysts, and the emergence of integrated biorefinery models supported by computational optimization tools. The analysis highlights that palm biomass residues, far from being an environmental liability, constitute strategic resources for low-carbon value chains. However, scaling IS initiatives requires clear public policies, economic incentives, and stronger coordination between industry, government, and academia. The study provides a structured overview of current knowledge, identifies research gaps, and outlines future directions for leveraging oil palm residues as a key input for sustainable IS.

In Colombia, two main palm varieties, Elaeis guineensis and Elaeis oleifera, are cultivated for the production of crude palm oil (CPO). During the CPO extraction process, several residues are generated, including empty fruit bunches (EFB), nut fiber, palm kernel cake, and Palm Oil Mill Effluent (POME), among others. These residues are commonly used for biochar and compost production to improve soil quality, for biogas generation, and for energy production through biomass combustion. Because the rachis is rich in lignocellulosic material and exhibits physicochemical properties suitable for thermochemical processes, it is proposed as a feedstock for hydrogen synthesis through gasification. In this study, a techno-economic analysis and an FP²O resilience assessment were conducted for a hydrogen production process based on the utilization of palm rachis generated in María la Baja, northern Colombia. The economic evaluation results indicate that the capital investment required for plant installation is USD 10,111,255.23. The economic indicators show favorable performance with a Return on Investment (ROI) of 58.83%, a Net Present Value (NPV) of USD 25.01 million, a B/C ratio of 3.29, and a Discounted Payback Period (DPBP) of 4.54 years. Regarding techno-economic resilience, critical values for processing capacity, selling price, and feedstock cost were identified through parameter variation. The findings suggest that the process has opportunities for improvement, since small changes in these variables could significantly reduce its resilience. Finally, an On-Stream efficiency of 39.65% at the break-even point was obtained, indicating that the process can operate at less than 50% of its maximum capacity while still generating significant profits.

The codling moth (Cydia pomonella L.) is a major pest of pome fruits worldwide, guided by semiochemicals to locate hosts and oviposition sites. Quince (Cydonia oblonga Mill.), although less studied, is also affected by this pest. This study aimed to identify behaviorally active compounds for codling moth by characterizing the volatilome of quince cultivars. Volatile profiles were analyzed across four phenological stages (flowering, unripe, growth, and ripe fruit) using solid-phase microextraction and GC–MS. The cultivars evaluated were Champion, INTA 37, INTA 117, and INTA 147. Female oviposition behavior and neonate larval host choice were also assessed. Identified volatiles included esters, sesquiterpenes, monoterpenes, alcohols, aldehydes, and norisoprenoids. Among monoterpenes, limonene, consistently detected across all cultivars and stages, emerged as a key kairomone. Volatile composition varied across phenological stages, with the fruit growth stage exhibiting the highest diversity and abundance of compounds previously reported as behaviorally active. This pattern coincided with peak female oviposition and larval host selection. Females oviposited mainly on leaf surface, whereas during ripening, eggs were deposited on fruit lacking pubescence. Overall, INTA 147 was the most preferred cultivar. These findings highlight quince volatiles, particularly Limonene, as potential candidates for the development of semiochemical-based tools to improve codling moth management. Full article

Carposina sasakii Matsumura is a significant lepidopteran pest in the Carposinidae family, inflicting substantial damage on stone and pome fruit trees such as jujube, peach, and apple. Using MaxEnt, we assessed the worldwide climatic suitability for C. sasakii and its key environmental drivers, evaluating how climate change impacts dispersal risks. Integrating global occurrence records with 37 environmental variables, the model (AUC = 0.982) quantitatively identifies July precipitation (prec7), minimum average temperatures in April and August (tmin4 and tmin8, respectively), and maximum average temperature in May (tmax5) as critical distribution determinants. Among these, prec7 exhibits the highest contribution (threshold approximately 370 mm). The current suitable habitat spans 10.39 × 10² km², concentrated predominantly in East Asia’s temperate monsoon zone (eastern China, the Korean Peninsula, and Japan) and southern North America. Under future climate scenarios, the high-emission pathway (SSP585) will reduce highly suitable areas, while moderately suitable zones expand coastward. In contrast, SSP370 projects a significant, albeit phased, habitat increase with a 19.61% growth rate. Precipitation regimes and extreme temperatures jointly regulate niche differentiation in C. sasakii, whose range shifts toward Southeast Asia and suboptimal regions in Europe and America, underscoring cascading climate change effects. These findings provide a scientific basis for transnational monitoring, early warning systems, and regional ecological governance. Full article
