The coffee plant, Coffea spp., is affected by several diseases that represent the main limiting factor to its production potential, with emphasis on diseases caused by soil-borne pathogens, especially phytonematodes of the genus Meloidogyne Göldi, 1887. Two experiments were carried out. The first, in a greenhouse from September 2024 to January 2025, evaluated the effect of M. incognita (Mi) parasitism on the morphological, nutritional, and genetic resistance characteristics of C. canephora (Cc) genotypes. The experiment was carried out for 90 days in CRD in a 7 x 2 factorial scheme (6 genotypes of C. canephora: A1, MC7, K61, AS2, R8 and R22 and LB1 clonal var. Jequitibá: susceptibility pattern to Meloidogyne spp.) x 2 nematode inoculum levels (0 and 5,000 individuals/plant) with 7 replicates for each inoculum level. The second experiment, carried out between January and May 2025, was identical to the first, except that the genotypes were inoculated with M. paranaensis (Mp). In both experiments, nematode reproduction, plant growth, nutrient concentration, and anthocyanin and flavonoid levels in leaves were evaluated, as well as total soluble phenol concentration in roots. Genotypes A1 and K61 inoculated with M. incognita had RF values less than 1 and were considered resistant. The other genotypes had RF values greater than 1 and were susceptible. Regarding the genotypes inoculated with M. paranaensis, except for LB1, the others had RF values less than 1 and were resistant. Whether comparing within the same period (0 or 90 days after inoculation, DAI) or between different evaluation periods, the means of the evaluated variables did not follow the same trend. That is, for some genotypes susceptible to M. incognita or M. paranaensis, there was a reduction in the evaluated variables, as expected. On the other hand, some resistant clones also showed a reduction in these variables. It was also noted that in some evaluations, susceptible genotypes showed an increase in the studied variables, and resistant genotypes showed a reduction

Qualidade sensorial e características físico-químicas de genótipos de Coffea arabica l. submetidos a diferentes tempos de fermentação
(Universidade Federal do Espírito Santo, 2025-02-25) Alixandre, Ricardo Dias; Ferreira, Adésio; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; Lopes, José Carlos; https://orcid.org/; http://lattes.cnpq.br/; Soua, Matheus Fonseca de; https://orcid.org/; http://lattes.cnpq.br/
The growing demand for coffees with high sensory quality drives the need for improvements and refinements in production processes. In this circumstance, it is crucial to recognize that the quality of the coffee beverage is the result of the complex interaction between three fundamental elements: the cultivation environment, the genetic composition of the plants and the management practices adopted. In this context, the objective of this study was to analyze the sensory quality of the beverage and the physicochemical characteristics of the beans of Arabica coffee genotypes, subjected to different times of spontaneous fermentation during post-harvest processing, aiming to optimize and adapt the production system. The experiment was carried out in the municipality of Afonso Cláudio-ES, located at 1000 meters above sea level. The experimental design adopted was randomized blocks, in a double factorial scheme, with five genotypes (Catucaí-785/15, Catucaiam 785/15, Águia, Arara and Colômbia) and six fermentation times (0; 12; 24; 36; 48 and 60 hours), with four replicates and seven plants per plot. Management practices strictly followed the recommendations established by the technical standards for the crop. The samples were harvested manually, with selection of ripe beans, which underwent a process of cleaning, selection and removal of the husk, and were then stored in plastic buckets, with water in the proportion of 30% in relation to the volume of coffee, for: 0; 12; 24; 36; 48 and 60 hours. At the end of each period, the samples were sent to the drying process until they reached a moisture content of 11 ± 1% (wet basis, BU), and the following analyses were performed: sensory analysis of the beverage, according to the SCA methodology; granulometric analysis of the grains and potassium leaching. The Águia genotype presents the highest average final beverage score, regardless of the fermentation time analyzed. The fermentation times analyzed do not demonstrate a significant influence on the final beverage score. There is a variation in sensory diversity between the genotypes and the fermentation times. The Águia genotype reaches the greatest sensory diversity after 24 hours of fermentation; the Colômbia genotype, after 48 hours; the Arara genotype with zero and after 24 hours; the Catucaí 785/15 genotype, after 36 hours; and the Catucaiam 78515 genotype, after 60 hours of fermentation. There are significant variations between the genotypes in relation to the grain size. The Catucaí 785/15 genotype presents the highest averages of sieve 17 and above in all fermentation times analyzed. In potassium leaching, the times of zero, 24, 36 and 48 hours of fermentation do not present a significant difference between the genotypes. The Catucai 785/15 and Colombia genotypes showed higher average potassium leaching at all fermentation times analyzed. The choice of genotype is a determining factor in the final quality of the beverage, in the grain size and in the physical-chemical stability of the grains. Further studies are needed to explore the interactions between these factors in different production environments

The indiscriminate use of synthetic petroleum-based polymers has caused serious environmental impacts, mainly due to their low degradability, accumulation in terrestrial and aquatic ecosystems, and the lack of efficient plastic waste management. In view of this issue, there is increasing interest in renewable and environmentally friendly alternatives capable of partially replacing conventional polymers in industrial and food applications. Among the emerging strategies, the valorization of lignocellulosic residues and the development of sustainable biopolymers stand out, integrating technological innovation, circular economy, and environmental conservation. In this context, the present study aimed to integrate food preservation strategies and forest residue valorization through three complementary chapters, addressing from the practical application of active packaging in postharvest management to the green extraction of biopolymers from forest by-products. In Chapter 1, the efficiency of active absorber sachets (zeolite, potassium permanganate, silver nitrate, and iron) was evaluated in the postharvest conservation of ‘BRS Fascínio’ peaches stored at 7 °C and 25 °C. Sachets containing potassium permanganate and iron proved to be the most effective, prolonging shelf life and preserving fruit quality. Chapter 2 presented a review on active and intelligent packaging, highlighting their role in sustainability and extending the shelf life of perishable products. In Chapter 3, the selective extraction of cellulose and lignin from the sterile bracts of Araucaria angustifolia was carried out using the ethanosolv process, which employs ethanol and hydrochloric acid. The cellulose showed Iβ polymorphism (2θ = 14.8°, 16.3°, 22.5°, 34.7°, 37°) and typical bands at 3330, 2890, 1160, and 897 cm⁻¹, while lignin exhibited bands at 3400, 1600, 1510, and 1265 cm⁻¹ and a residual band at 1740 cm⁻¹, indicating the presence of hemicellulose. It is concluded that the proposed approaches represent viable and environmentally safe alternatives for food preservation and sustainable biopolymer production, aligned with the principles of bioeconomy and circular economy
