The aim of this study was to evaluate the effect of different packaging, environment and storage time on the chemical quality of crambe seeds. Crambe seeds, with a water content of 4.63% (dry basis), were packed into high density polyethylene (HDPE), reused polyethylene terephthalate (PET) bottles and laminated packages, which were stored in two different environments: refrigerated air (RA) at 10 ± 1.19 °C and 34.84 ± 4.09% relative humidity (RH) and natural air (AN) at 24.81 ± 1.82 °C and 54.93 ± 12.77 % RH. For nine months, the oil and crude protein content, acidity index, peroxide and iodine level, pH, and alcohol-soluble acidity were evaluated. Seeds in laminated packages stored in AN showed higher crude protein content after 3rd month, and in AR, there were higher levels of peroxide after 3rd and 6th months. In AR, the seeds in HDPE packaging showed lower alcohol-soluble acidity. Crude protein and oil content decreased during storage, peroxide level and pH increased and iodine level varied. At the end of storage, the alcohol-soluble acidity returned to base line values. The acidity level was not affected by the changes in the variables studied. © 2015, Departamento de Engenharia Agricola - UFCG/Cnpq. All rights reserved. Source

The present study aimed to evaluate the physiological quality of seeds of crambe in different storage conditions for nine months. The crambe with moisture content of 4.63% (wet basis) was placed in the packages laminated, PET and HDPE, which were stored in environments: refrigerated at 10 ± 1.19 °C and 34.84 ± 4.09% relative humidity (RH) and natural at 24.81 ± 1.82 °C and 54.93 ± 12.77% RH. The completely randomized design in triple factorial (3 × 2 × 4) with three replications was used. Data were analysed by analysis of variance and regression. The natural environment and packaging PET containers is best to maintain seed quality of crambe for up to six months of storage. The natural environment preserves the seed vigor and promotes overcome primary dormancy as early as the third month of storage. The refrigerated environment at 10 °C is not recommended for storage of seeds of crambe. © 2015, Departamento de Engenharia Agricola - UFCG/Cnpq. All rights reserved. Source
