Background/Objectives: Traditional kombucha is produced by fermenting a sweetened infusion of Camellia sinensis leaves with a symbiotic consortium of bacteria and yeasts (SCOBY). The growing interest in this beverage has driven the exploration of alternative substrates, including a wide range of plant-based raw materials, such as leaves, fruits, flowers, and seeds. Consequently, numerous products are being investigated for their differential properties, not only organoleptic but also nutritional and bioactive. This review aims to summarize recent advances in alternative kombucha research, focusing on the substrates used, their physicochemical and biochemical characteristics, and the biological activities studied. Methods: A comprehensive literature search was conducted to select articles related to alternative kombuchas. A critical analysis of their current state was carried out through the Strengths, Weaknesses, Opportunities, and Threats (SWOT) methodology. Results: The SWOT analysis led to the identification of strengths, including promising in vitro results and growing consumer interest; weaknesses, including a lack of animal studies, clinical trials, and approved health claims, and an excessive focus on antioxidant activity and phenolic compounds; opportunities, including substrate diversity, innovation, and consumer education; and threats, including elaboration risks, misinformation, competitors, and potential consumer rejection. Conclusions: Despite the promising results achieved to date, it is essential that the scientific community and the food industry continue efforts to generate robust evidence, particularly through clinical validation, in order to draw reliable conclusions regarding the benefits of alternative kombuchas for human health.

Andean berry (Vaccinium meridionale Swartz) is a species of berry mostly exclusive to the Andean ecosystems, mainly present in Colombia, Venezuela, Peru, and Jamaica, where it grows between 2000 and 3000 m.a.s.l. Although most of the fruit is harvested naturally, limited fruit production significantly restricts large-scale farming and sales. Most research on phytochemicals from this berry has focused on polyphenolic compounds, particularly anthocyanins such as cyanidin-3-O-galactoside and delphinidin-3-O-hexoside. These compounds have significant antioxidant potential and require appropriate post-harvest handling to preserve their stability and biological functionality. A systematic literature search was conducted covering studies from January 2000 to January 2025 across Scopus, PubMed, Web of Science, and Google Scholar. Evidence from original research includes chemical analyses, in vitro biological activity, in vivo effects in animal models, and clinical studies. Although findings suggest antiproliferative, chemoprotective, and cardioprotective properties, current evidence remains largely preclinical, and clinical validation is urgently needed. Despite its promise, challenges persist in standardizing cultivation, scaling production, and optimizing post-harvest. The berry has been incorporated into food products, but further research is essential to support its transition from experimental use to validated clinical applications. Full article

Plant growth regulators (PGRs) such as aminoethoxyvinylglycine (AVG), 1-methylcyclopropene (1-MCP), and thidiazuron (TDZ) are widely used to improve fruit set and quality in stone fruits. This study evaluated the effects of these PGRs on fruit set, yield performance, and fruit quality parameters of the Japanese plum cultivar ‘Leticia’ under the edaphoclimatic conditions of the highland region of southern Brazil during the 2021/22 and 2022/23 growing seasons. The treatments (AVG, MCP, and TDZ) were applied in full bloom in a randomized complete block design with four replications, and the data from both seasons were analyzed by principal component analysis (PCA). All PGRs significantly affected fruit set, yield performance, and fruit quality parameters. The strongest associations were found with 182 mg L⁻¹ TDZ for fruit set, and with 62.5 mg L⁻¹ and 125 mg L⁻¹ AVG, and 21.43 mg L⁻¹ 1-MCP for yield performance-related trails. Applications of 125 mg L⁻¹ AVG, 21.43 mg L⁻¹ 1-MCP, and 182 mg L⁻¹ TDZ produced fruits with larger diameters and higher fresh weights. The PCA results indicated that TDZ at 182 mg L⁻¹ was closely associated with fruit set and yield performance, suggesting a strong multivariate relationship among these parameters and demonstrating its potential to enhance the productivity of ‘Leticia’ plum under the edaphoclimatic conditions of southern Brazil during the 2021/2022 and 2022/2023 growing seasons.

Cytokinin- and Auxin-Based Plant Growth Regulators (PGRs) are commonly employed to increase fruit size due to their ability to modulate cellular structure. This study aimed to evaluate the effects of different PGR application protocols on histological parameters, yield components, and fruit quality in ‘Maxi Gala’ apple. The experiments were carried out under humid subtropical conditions of southern Brazil across two growing seasons (2021/22 and 2022/23), allowing comparison of treatment performance under distinct climatic patterns. Data from common treatments were combined across years for integrated analysis. The PGRs used included 6-benzyladenine (BA) as a cytokinin source; naphthalene acetic acid (NAA) as an auxin source; and tryptophan, a precursor of auxin biosynthesis. PGRs were applied in various combinations and concentrations between 10 days after dormancy break (BBCH 01) and fruit diameters of 25–27 mm (BBCH 74), following a randomized block design with four replicates of twelve trees each. The multivariate analysis of treatments was performed using Principal Component Analysis (PCA). Additionally, an analysis of variance was performed for flesh firmness loss, with means compared using Tukey’s test (p < 0.05). PGRs significantly influenced only the histological parameters of the fruit flesh tissues. BA and tryptophan had the greatest effects on cell size and cell number in the fruit flesh, respectively, both reducing intercellular spaces. Tryptophan was associated with a higher number of smaller cells, whereas NAA promoted larger cell sizes. The combination of BA and NAA, as well as a single application of BA at petal fall, resulted in the highest yield performances and increased the proportion of large fruits. Furthermore, BA enhanced the percentage of red skin coloration and improved flesh firmness during storage. Full article

Growing market demand exists for strawberry, with nutrient-rich and health-promoting properties, beyond mere taste and flavor. Genetic biofortification is a powerful strategy to enhance nutrient metabolites in strawberry. Both GABA and organic acids contribute to human health by supporting nervous system relaxation and enhancing metabolic and digestive functions, respectively. However, the regulatory mechanisms underlying their accumulation remain poorly understood. In this study, we analyzed the accumulation patterns of GABA and organic acids across four fruit developmental stages in two representative cultivars, ‘Monterey’ and ‘Benihoppe’. Ripening ‘Benihoppe’ fruits accumulated higher levels of GABA and citric acid, whereas ‘Monterey’ fruits contained more malic acid. Integrated transcriptome analysis identified key structural genes and transcription factors (TFs) involved in GABA biosynthesis. Notably, functional characterization revealed that FaGAD4 significantly promotes GABA accumulation and simultaneously enhances the content of anthocyanin and ascorbic acid (AsA). Overall, this study provides novel insights into the regulatory mechanisms of GABA accumulation in strawberry fruit and identifies FaGAD4 and potential TFs as valuable genetic targets for molecular breeding.

Background/Objectives: Type 2 diabetes mellitus (T2DM) represents a growing public health burden in the European Union (EU), largely driven by modifiable lifestyle factors such as diet. This systematic review aimed to synthesize observational evidence on the associations between nutritional exposures and incident T2DM across the EU-28, with a focus on regional heterogeneity and implications for EU-level nutrition policy. Methods: The review followed PRISMA 2020 guidelines and was registered in PROSPERO (CRD42020219994). Searches were conducted in different databases (PubMed, Embase, Scopus, Web of Science) identifying 23,437 records, from which 104 observational studies were included. Eligible studies involved adults (≥18 years) without T2DM at baseline and assessed dietary exposures in relation to T2DM incidence. Data extraction and methodological quality assessment were performed in duplicate using the NHLBI tool in Covidence. Results: Most included studies were cohort studies (77.9%), primarily conducted in Western, Northern, and Southern Europe. Diets characterized by high consumption of whole and minimally processed foods, such as fruits, vegetables, legumes, whole grains, and fermented dairy, consistently showed associations with lower T2DM risk. In contrast, high intake of red and processed meats, sugar-sweetened beverages, and ultra-processed foods was linked to higher risk. Adherence to Mediterranean or plant-based dietary patterns was associated with lower risk, whereas high animal-protein dietary patterns were detrimental. Conclusions: Nutritional determinants play a decisive role in shaping T2DM risk in the EU. Evidence supports prioritizing dietary patterns rich in plant-based and minimally processed foods while reducing ultra-processed and meat-based products. Tailored region-specific policies are needed to address the T2DM epidemic and guide effective prevention strategies. Full article

Colorectal cancer (CRC) is the third most common cancer worldwide, imposing a significant burden on public health. Despite the use of various therapeutic strategies, the prognosis for patients with metastatic and drug-resistant CRC remains poor, which underscores the need for further investigations into cancer mechanisms to develop more effective treatments. Rodents, particularly mice, are the most frequently used animal models for CRC research. However, as the demand for more precise simulations and higher ethical standards in animal experimentation grows, the applicability of rodent models may face increasing limitations. This review highlights a variety of non-rodent animals, including model organisms such as zebrafish (Danio rerio), fruit flies (Drosophila melanogaster), and Caenorhabditis elegans (C. elegans), as well as the chorioallantoic membrane (CAM) model and mammals such as rabbits (Oryctolagus cuniculus), dogs (Canis lupus familiaris), and pigs (Sus scrofa domesticus), which have been utilized in CRC research. Each of these alternatives offers specific advantages in certain areas of cancer research. Their use has enabled new insights into the mechanisms of carcinogenesis, metastasis, and drug resistance in CRC, as well as the development of novel therapies. Full article

The jacaranda (Jacaranda mimosifolia D. Don.) is a widely cultivated ornamental tree species in urban landscapes, but recent research has highlighted its additional ecological and industrial potential. However, no detailed phenological description has been available for this species. The objective of this study was to establish a standardized phenological scale for Jacaranda mimosifolia D. Don. based on the BBCH coding system and to determine the thermal requirements (growing degree-days, GDD). Thirty-nine secondary stages were used to describe the life cycle of jacaranda in this BBCH scale, distributed across seven principal growth stages (PGSs). Of these thirty-nine secondary stages, five stages correspond to dormancy and sprouting (PGS-0), six stages correspond to leaf development (PGS-1), three correspond to the emergence of the flowering organ (PGS-5), eight correspond to flowering (PGS-6), ten correspond to fruit formation (PGS-7), three correspond to ripening fruit (PGS-8), and four correspond to the beginning of dormancy (PGS-9). Thermal integral analysis indicated that jacaranda requires approximately 3800 accumulated degree-days (GDD) to progress from dormancy to leaf fall. This phenological framework enhances understanding of the growth cycle of Jacaranda mimosifolia D. Don. and provides a useful reference for improving the timing and efficiency of management and phytosanitary treatments in Mediterranean conditions. Full article

Food production is among the most environmentally intensive human activities, and its impacts are intensifying under population growth and increasingly resource-demanding consumption patterns. Agricultural practices have responded through the expansion of irrigated croplands, aiming to secure food supply but also fostering a complex agribusiness system with inherent contradictions. A central issue is the systematic overproduction of perishable crops. When supply surpasses demand, prices often fall below production costs, resulting in the routine disposal of large volumes of fresh produce—frequently before entering distribution channels. This study quantifies the environmental burden of this waste by calculating the water and carbon footprints of discarded fruits and vegetables in Spain between 2018 and 2024, based on official data. Across this period, 483,624 tons of surplus produce were discarded, equivalent to a water footprint of nearly 36 hm³ and a carbon footprint of 36,694 tCO₂-eq. In a region already facing severe water stress, widespread groundwater overexploitation, and growing dependence on inter-basin transfers and desalination, such chronic waste represents a significant inefficiency. The results highlight the urgent need to reassess current food production practices and address systemic imbalances to support a more sustainable and resource-efficient agricultural model.

Background/Objectives: Migrants are recognized as a vulnerable population for non-communicable diseases (NCDs) due to unique socio-cultural and environmental challenges associated with acculturation. Despite a growing migrant population, evidence on NCD risk among migrants in Japan is scarce. This study examined the prevalence, co-occurrence, and clustering of modifiable NCD risk factors among middle-aged foreign residents in Japan. Methods: A cross-sectional web-based survey was conducted among foreign residents aged 30–60 years (n = 384). Eight risk factors were assessed: tobacco use (including cigarettes, e-cigarettes, and chewable tobacco), harmful alcohol consumption, inadequate fruit and vegetable intake, frequent consumption of ultra-processed foods, insufficient physical activity (PA), poor sleep, high stress levels, and high BMI. Latent class analysis (LCA) was used to identify risk clusters, and associations with demographic and socioeconomic characteristics were examined. Results: The prevalence of risk behaviours was high, with 96% reporting inadequate fruit and vegetable intake, 55% poor sleep, and 50% insufficient PA. Risk factor co-occurrence was common: 32% reported three concurrent risks, 27.1% reported four, and 17.2% reported five or more. LCA identified two clusters. Cluster 1 (46.9% of participants) was characterized by tobacco and alcohol use, with inadequate diet and poor sleep. Cluster 2 (53.1% of participants) was defined by insufficient PA, inadequate diet, and poor sleep, but low tobacco and alcohol use. Cluster membership varied significantly by sex and employment. Conclusions: This study provides preliminary evidence of the high prevalence and clustering of modifiable NCD risk factors among middle-aged migrants in Japan. Findings highlight the need for comprehensive, multi-behavioral interventions tailored to migrant populations, while considering gender roles and occupational contexts. Full article

The growing consumer interest in plant-based alternatives has encouraged the development of non-dairy versions of traditionally dairy-based products such as ice cream and frozen desserts. Soy milk, with its high protein content and favorable nutritional profile, is a promising alternative to cow’s milk in frozen desserts. The aim of this study was to develop frozen dessert recipes containing soy milk and assess their physical, chemical, and sensory properties. Physicochemical analyses of frozen dessert included measurements of pH, specific gravity, total solids, moisture content, ash content, overrun, and melting resistance. Air sell size distribution was examined microscopically. Sensory evaluation was conducted by a trained panel. Nutritional composition was also analyzed. The pH of the frozen dessert increased from 7.2 to 7.5 with higher soy milk content. Specific gravity of the frozen dessert rose from 589.0 to 634.4 kg/m³, while total solids content increased from 20.61 to 28.99%, and ash content rose from 0.33 to 0.98%. Overrun of the frozen dessert dropped from 73.2% to 50.1%, and melting resistance declined from 72.8% to 54.1% with increased soy milk levels. Frozen dessert samples containing soy milk demonstrated high sensory scores due to their smooth texture, pleasant flavor, and uniform consistency. Replacing cow’s milk with soy milk in frozen dessert recipes is a feasible strategy for producing plant-based frozen desserts with acceptable quality and improved nutritional attributes. Future research should explore flavor enhancement and functional enrichment, particularly through the incorporation of freeze-dried fruits and berries, to diversify the product range and meet consumer demands for health-oriented desserts. This research supports sustainable food innovation by reducing dependence on animal-derived ingredients and promoting the use of plant-based proteins. The development of soy milk-based frozen dessert aligns with global efforts to lower the environmental impact of food production and respond to growing consumer demand for eco-conscious dietary choices.

Bud break is a critical phenological stage in muscadine grapevines, marking the start of the growing season and the increasing need for irrigation management. Real-time bud detection enables irrigation to match muscadine grape phenology, conserving water and enhancing performance. This study presents BudCAM, a low-cost, solar-powered, edge computing camera system based on Raspberry Pi 5 and integrated with a LoRa radio board, developed for real-time bud detection. Nine BudCAMs were deployed at Florida A&M University Center for Viticulture and Small Fruit Research from mid-February to mid-March, 2024, monitoring three wine cultivars (A27, noble, and Floriana) with three replicates each. Muscadine grape canopy images were captured every 20 min between 7:00 and 19:00, generating 2656 high-resolution (4656 × 3456 pixels) bud break images as a database for bud detection algorithm development. The dataset was divided into 70% training, 15% validation, and 15% test. YOLOv11 models were trained using two primary strategies: a direct single-stage detector on tiled raw images and a refined two-stage pipeline that first identifies the grapevine cordon. Extensive evaluation of multiple model configurations identified the top performers for both the single-stage (mAP@0.5 = 86.0%) and two-stage (mAP@0.5 = 85.0%) approaches. Further analysis revealed that preserving image scale via tiling was superior to alternative inference strategies like resizing or slicing. Field evaluations conducted during the 2025 growing season demonstrated the system’s effectiveness, with the two-stage model exhibiting superior robustness against environmental interference, particularly lens fogging. A time-series filter smooths the raw daily counts to reveal clear phenological trends for visualization. In its final deployment, the autonomous BudCAM system captures an image, performs on-device inference, and transmits the bud count in under three minutes, demonstrating a complete, field-ready solution for precision vineyard management.
