Fusarium species produce toxic mycotoxins that are known to exert adverse health effects in humans and animals. No attempts have been made to establish mycotoxin-producing capabilities of isolates of Fusarium species from bananas exhibiting symptoms of crown rot. Crown rot is one of the most serious post harvest problems in banana and the disease is caused by different fungal species, principally Fusarium species. Banana, which is of great economic significance in growing countries (i.e. Costa Rica, Cameroon, Ecuador) is seriously affected by crown rot and is a major cause of fruit loss

Além disso, o intuito deste trabalho foi comparar o ângulo de repouso das sementes em diferentes protótipos. O estudo foi realizado no laboratório da Universidade Federal Rural da Amazônia, Tomé-Açu (PA), para verificar: teor de água, biometria, esfericidade, volume unitário, porosidade e ângulo de repouso. O teor de água utilizou cinco amostras (50 sementes), biometria obteve eixos ortogonais de 100 sementes, e utilizadas 20 sementes para esfericidade e volume unitário. Ainda, obtidas médias em 3 equipamentos de ângulo de repouso, (5 repetições). Como resultado, o teor de água (b.u.) foi baixo, (0 a 10%); a esfericidade variou de 61,45 a 90,66%; volume unitário foi de 0,03 a 0,13 cm3 e as porosidades foram (0,69, 0,77 e 0,78). Os ângulos de repouso nos equipamentos (A- adaptado em relação a B; B- equipamento estabelecido e C- protótipo alternativo) foram, respectivamente: 38,85; 31,92 e 32,14°, não diferindo estatisticamente. Ademais, o estudo buscou trazer informações sobre a espécie e colaborar com trabalhos de construção, operação e adaptação de equipamentos de secagem e armazenamento.   Palavras-chave: esfericidade, porosidade, volume unitário.   PHYSICAL CHARACTERIZATION OF ANNATTO (Bixa orellana L.) SEEDS, AIMED POST-HARVEST PROCESSES   ABSTRACT: Annatto demonstrates economic importance in the commercialization of ground grains for color and dye production; however, there are few studies on their physical characteristics in post-harvest processes. In addition, the aim of this work was to compare the rest angle of seeds in different prototypes. The study was carried out in the laboratory of Federal Rural University of the Amazon, Tomé-Açu (PA), to verify: water content, biometrics, sphericity, unit volume, porosity and angle of repose. The water content used five samples (50 seeds), biometrics obtained orthogonal axes of 100 seeds, and 20 seeds were used for sphericity and unit volume. Still, averages were obtained in 3 equipment of angle of rest (5 repetitions). As result, the water content (b.u.) was low (0 to 10%); sphericity ranged from 61.45 to 90.66%; unit volume was 0.03 to 0.13 cm3 and porosities were 0.69, 0.77 and 0.78. The rest angles in the equipment (A- adapted in relation to B; B- established equipment and C- alternative prototype) were, respectively: 38.85; 31.92 and 32.14°, not differing statistically. In addition, the study sought to bring information about the species and collaborate with construction, operation and adaptation of drying and storage equipment.   Keywords: sphericity, porosity, unit volume.

The department of Huila is a producer of Castilla blackberry (Rubus glaucus Benth), a perishable fruit in post-harvest, making it necessary to develop processing alternatives in order to extend its shelf life and improve its market price. It was therefore proposed to elaborate a fermented blackberry drink using clarification, maturation, and aging processes. The physiochemical and microbiological parameters were characterized in the different phases. The inoculated yeast generated changes during the fermentation of the blackberry juice reducing the soluble solids to 6.9°Brix and viscosity to 1.5 cP. The alcohol content at the end of the process was of 14.4 alcohol by volume (ABV).
