Title: Características físico-químicas de microverdes de lentilha: resultados em solo tratado com diferentes concentrações de selênio (Lens culinaris Medik) Abstract: Although lentils (Lens culinaris Medik) are widely consumed as whole seeds, they remain largely unexplored as microgreens. Microgreens have gained attention for their high nutritional value and the presence of bioactive compounds, and are considered promising foods for promoting health. In this context, the present study aimed to evaluate the physicochemical characteristics and the content of bioactive compounds in lentil microgreens subjected to biofortification with selenium, in the forms of sodium selenate and sodium selenite, at different concentrations. The lentil seeds were supplied by EMBRAPA, and the microgreens were grown for 12 days at the Seed Laboratory of the Federal University of Uberlândia, Umuarama campus. Soil treated with different concentrations of selenium (0, 1, 5, 10, and 20%) was used. Analyses were conducted to determine moisture content, protein content using the Kjeldahl method, antioxidant activity using the DPPH method, and quantification of carotenoids and chlorophylls (a, b, and total). The results were analyzed using a completely randomized design in a factorial scheme (2 × 4) + 1 additional treatment. The microgreens had a high moisture content, ranging from 88.8% to 89.8%, with no significant differences among the treatments. Protein content (%) showed a significant increase in the treatments with sodium selenite, particularly at the 5% concentration (61.4%), which was higher than that of the control (42.4%). Regarding antioxidant activity (%AA), the highest values were observed in the selenite treatments at concentrations of 10% (20.50%AA) and 20% (29.20%AA), differing significantly from the control (11.63%AA). For carotenoids (mg/g), the highest levels were observed at concentrations of 20% selenate (0.1416 mg/g) and selenite (0.1504 mg/g). The highest values of total chlorophyll (μg/g of dry matter) were obtained with 20% selenite (2.0881 μg/g of dry matter). Overall, it was found that the response of the microgreens varied according to the chemical form and concentration of selenium applied, with sodium selenite standing out as it promoted the greatest increase in antioxidant, protein, and photosynthetic pigment parameters. Thus, selenium biofortification demonstrated potential to increase the nutritional and functional value of lentil microgreens, highlighting its applicability in the development of foods with higher added value.

Title: Plataformas informatizadas para a gestão do Programa Municipal de Alimentação Escolar em Uberlândia: um estudo de caso Abstract: The management of the National School Feeding Program (PNAE) in large municipalities faces significant operational challenges. In Uberlândia, many key processes in the management of the Municipal School Feeding Program (PMAE), such as menu planning and stock control, remain dependent on manual methods or fragmented spreadsheets, generating risks of errors, rework, and low transparency. The objective of this work was to analyze the feasibility of the tools currently used and to assess the need for computerization of PMAE management in Uberlândia. The methodology adopted a qualitative-quantitative approach, configured as a case study. A structured questionnaire was administered to the entire technical staff (n=20) of the program's nutritionists, yielding a 100% response rate. The instrument used the Technology Acceptance Model (TAM) to measure receptivity to innovation. The quantitative results confirm the operational bottlenecks: the perception of integration between sectors is low (mean 2.5/5), and the frequency of rework is considered high (mean 3.3/5). The main challenges identified were the "Lack of data standardization" (26.6%) and the "Difficulty in finding updated information" (21.9%). Conversely, the TAM results revealed an ideal human receptivity, with high means for Perceived Usefulness (4.8/5), Perceived Ease of Use (4.7/5), and a unanimous Behavioral Intention to Use (5.0/5). It is concluded that the implementation of an integrated digital platform is not only an urgent necessity to overcome the diagnosed bottlenecks but also highly viable, given the technical staff's complete receptiveness to the concept.

Title: Terceirização dos serviços de nutrição em hospitais: impactos na qualidade e na segurança alimentar Abstract: Outsourcing nutrition services in healthcare institutions has become a widely adopted strategy to optimize resources, reduce costs, and enhance operational efficiency. However, its effectiveness depends directly on the quality of oversight and contractual control mechanisms. This study aimed to evaluate the services provided by an outsourced nutrition company in a hospital from 2022 to 2024. The Results Measurement Instrument (RMI) served as the basis for analysis. The research used both qualitative and quantitative approaches, relying on the documentary analysis of technical inspection reports provided by the hospital. The data were organized into graphs and discussed alongside the literature on outsourcing and quality management in hospital services. The results indicate that, between april/2022 and august/2024, the indicators of punctuality, adequacy of non-conformities, specification of supplies, hygienic conditions, and general supervision showed fluctuations. However, they did not demonstrate consistent improvement. Conversely, microbiological control exhibited a continuous growth trend. This established it as a critical point for management to prioritize. The percentage of contractual discount decreased significantly throughout 2023, but increased again in 2024, particularly in January and July. These increases signaled setbacks in service quality. The overall score, in turn, rose. This should be interpreted as a negative result, since it indicates a greater number of nonconformities. Thus, outsourcing proves to be a viable strategy for hospital management, provided it includes effective and systematic monitoring and evaluation instruments. The IMR helped identify failures and opportunities for improvement, although it needs refinements. Future studies should expand the sample and include user perceptions.
