1. Effect of water activity and storage of tahini on the viability of stressed Salmonella serovars
Abstract Tahini (sesame seed paste) is a low water activity product that has been involved in several salmonellosis outbreaks. The objectives of the study were to examine over a year the impact of aw and storage temperature of tahini on the viability of Salmonella serovars previously stressed by drying or heat exposure. Tahini samples adjusted to aw values o

2. Physical and physiological quality of rice seeds in function of drying temperature and storage
ABSTRACT The objective with the work was to evaluate, during storage, the rice seeds physical and physiological quality, cultivar IRGA 424 RI, dried with different drying air temperatures. For such, rice seeds were harvested with a moisture content of 22%. Then, they were subjected to drying in a cross-flow dryer, operating in an intermittent system and usin

3. Artificial drying of safflower seeds at different air temperatures: effect on the physiological potential of freshly harvested and stored seeds
Resumo: A temperatura do ar empregado no processo de secagem pode determinar a qualidade fisiológica inicial e o potencial de armazenamento de um lote de sementes, sendo esse o objeto de estudo desta pesquisa. Sementes de cártamo, colhidas com teor de água de 25,8%, foram submetidas à secagem em secador experimental às temperaturas do ar de 40, 50, 60 e

4. Analysis of radiographic images and germination of Campomanesia pubescens (Mart. ex DC.) O.Berg (Myrtaceae Juss.) seeds under drying
Resumo O objetivo deste trabalho foi avaliar a morfologia interna de sementes de Campomanesia pubescens (Mart. ex DC.) O.Berg com diferentes teores de água por meio de análise de imagens de raios-X, e correlacionar as imagens com a germinação dessas sementes. Os frutos foram coletados no município de Jataí, Goiás, Brasil, e levados ao Laboratório de

5. Immediate and latent effects of drying soybeans with dehydrated air
ABSTRACT. New grain drying techniques have been improved to reduce post-harvest losses. The electric air dehumidifier (UTA 60®) is an example; it was installed at the ELLITT Seed Company for drying soybean seeds (TEC 7849) with random sample collection (DIC). Our objective was to evaluate the immediate and latent effects of the dehumidified air on the vigou

6. Temperatures and periods of drying delay and quality of corn seeds harvested on the ears
Resumo: Sementes colhidas em espiga possuem elevados teores de água. Assim, o objetivo neste trabalho foi avaliar a perda de qualidade fisiológica de sementes de milho colhidas em espiga, em função do retardamento de secagem. As espigas de milho híbrido foram colhidas com 31% de umidade e submetidas ao atraso da secagem por 0, 12, 24 e 36 horas, sob as

7. MODELING OF THE KINETICS OF CRYOGENIC FREEZING OF LIMA BEAN SEEDS AS A FUNCTION OF INITIAL WATER CONTENT
ABSTRACT Cryopreservation is a technique used to preserve genetic material at ultra-low temperatures in cryogenic germplasm banks. In order to enable the cryopreservation of a seed, it is necessary to study its appropriate freezing temperature and its water content, because seeds reach maximum physiological quality with high water contents, and they tolerate

8. Seed priming improves the germination and growth rate of melon seedlings under saline stress
RESUMO: A germinação e o crescimento de plantas de melão (Cucumis melo L.) podem ser severamente afetadas pelo excesso de sais no solo ou na água de irrigação. No entanto, os efeitos negativos do estresse salino podem ser amenizados com o uso de métodos adequados de condicionamento das sementes. Assim, este estudo objetivou investigar os efeitos do o

9. Microencapsulation of grape seed oil by spray drying
Abstract In the search for alternative wall materials to replace gum Arabic (GA), a good but expensive encapsulating agent, this work aimed to evaluate the effectiveness of maltodextrin 10DE in combination with GA (GA/MD, 50:50 ratio) for the microencapsulation of grape seed oil by spray drying. The addition of maltodextrin to gum Arabic did not influence t

10. Drying and reduction in sensitivity to desiccation of seeds of Alibertia edulis: the influence of fruit ripening stage
ABSTRACT The intense environmental degradation in tropical regions suitable for agriculture has decreased native forest populations of plants with important fruits and medicinal properties. Alibertia edulis is a native tree from the Brazilian Cerrado. Knowledge about the effects of drying and storage on the physiological behavior of its seeds may aid in its

11. Relationship between seed moisture content and acquisition of impermeability in Nelumbo nucifera (Nelumbonaceae)
ABSTRACT Seeds of Nelumbo nucifera do not imbibe water, and thus have physical dormancy (PY). However, a proportion of seeds are permeable to water, and so we hypothesized that variation in moisture content is a reason for the development of both permeable and impermeable seeds. The permeable proportion of seeds present in a lot collected from Suzhou, China,

12. DRYING KINETICS OF NIGER SEEDS
ABSTRACT: The objectives of this study were to describe the process of drying niger seeds through the fitting of different mathematical models to the experimental drying data, to select the best model that represents the phenomenon, and to determine the diffusion coefficients and thermodynamic properties of the product. Seeds with an initial moisture content
