Vegetables are important in human diets as a side dish eaten either cooked or raw as in salads. They are important for their nutritional contribution as major sources of minerals, vitamins, nine essential amino acids, beneficial phytochemicals, fibre and interesting colour from an aesthetic point of view. Despite the immerse health benefits offered by vegetables there are challenges encountered in their post-harvest handling and storage up to consumption. Challenges include post-harvest losses due to diseases. Some losses occur even at household level when vegetables are not stored appropriately when stored under the sink where humidity can be high leading to an environment which promotes diseases. Diseases in the post-harvest chain are caused by bacteria and opportunistic pathogenic fungi. Post-harvest losses of vegetables are not only a threat to nutritional security but a threat to food security as well. The aim of this research study was to document major post-harvest diseases of vegetables found in the Kingdom of Eswatini and to suggest appropriate management strategies or ways of alleviating them.

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.

In the paper are presented results of grain outer quality loss investigation during its post-harvest treatment. Objective was to determine the grain damage during its transport by bucket elevators of type “SANFON” at bucket peripheral velocity 2.0 m/s and 2.8 m/sof capacity 40 t/hand 80 t/h, respectively. The damage was investigated at counter-flow and parallel-flow bucket filling. From the measured results resulted the conclusion, that the bucket elevators tend rather to grain crushing, i.e. fraction creation than to smaller damage. On basis of partial knowledge chain elevators have no significant tendency to fraction generation, but incline considerably to the transported grain total mechanical damage at performance significantly lower than is the nominal one. In that case total mechanical damage ranged from 1.78 to 1.98%. Auger conveyers tend rather to total mechanical damage of transported grain than to the fraction creation. This is caused mainly by the friction between the transported grain and transporting “trough”. Total mechanical damage is in range from 1.36 to 1.73%. Belt elevators are friendly to transported grain and therefore are evitable for grain horizontal transport in lines for reception, treatment and storage of food grain crops.

SUMMARYThe effect of three centres of production, two times of lifting and two post-harvest treatments of apparently virus-free seed tubers on sprout development at planting was studied over two seasons. Sprout length and degree of development were determined mainly by the light and temperature conditions during storage. Under similar storage conditions tubers from the most southern region, lifted early and allowed to sprout from lifting produced longer sprouts than those from the more northerly regions, lifted late and sprouted from midwinter. At planting all tubers had sprouts longer than 2·5 cm. Desprouted tubers from the more southern regions had the highest number of sprouts at planting and tubers 'greened' immediately on lifting had the least.An index of sprout development at planting was defined. The conditions and duration of storage had most influence on the degree of development as measured by this index; sprouts were most developed on tubers sprouted over a long period and on those sprouted in a heated glasshouse. The effects of varying centres of production and times of lifting on sprout development at planting were small compared with those readily produced by varying the storage conditions.

Abstract Tomato quality is determined by metabolite content which is governed by post-harvest physiological changes. A 30-day full factorial experiment investigated pre-packaging, disinfection and storage temperatures on 18 different biochemical, microbiological, enzymatic and subjective quality attributes of tomato quality. Principal component analysis revealed associations among the variables such as PC1 (28.85%): coliform/enzymatic softening; PC2 (21.52%): free sugars/sweetness; and PC3 (18.20%): sucrose hydrolysis/microbial spoilage/defense metabolites. Discriminant analysis showed that some specific parameters were highly significant (P<0.001) in determining quality changes in relation to the washing procedures and storage temperature. The prominence of ascorbic acid was observed in the equations which discriminate mostly on the basis of microbial deterioration. Further works in this respect entail fine-tuning through model verification of the equations. Multivariate analysis techniques are, therefore, recommended in studies whereby understanding of the phenomenon driving the post-harvest system’s dynamics has to be understood through diverse interrelated metabolic parameters.
