R E S U M OObjetivou-se, neste trabalho, avaliar o efeito de diferentes embalagens, ambientes e do tempo de armazenamento na qualidade de sementes de crambe. O crambe, com teor de água de 4,63% (b.u.), foi embalado em garrafas de polietileno de alta densidade (PEAD), em garrafas reutilizadas de polietileno tereftalato (PET) e em embalagens laminadas as quais foram armazenadas nos ambientes: refrigerado a 10 ± 1,19 °C e 34,84 ± 4,09% de umidade relativa (UR) e natural a 24,81 ± 1,82 °C e 54,93 ± 12,77% de umidade relativa (AN). Avaliaram-se, durante nove meses, o teor de óleo e de proteína bruta, os índices de acidez, peróxido e iodo, pH e acidez em álcool solúvel. As sementes acondicionadas em embalagem laminada no AN apresentaram maior teor de proteína bruta no 3° mês e as em AR, maiores índices de peróxido, nos 3° e 6° meses. Em AR, as sementes em embalagens de PEAD apresentaram menor acidez em álcool solúvel. Os teores de proteína bruta e de óleo diminuíram durante o armazenamento, o índice de peróxido e o pH aumentaram e o índice de iodo apresentou variação nos valores. No final do armazenamento os valores de acidez em álcool solúvel eram semelhantes aos do início. O índice de acidez não sofreu interferência das variáveis estudadas. Storage of crambe seeds in different containers and environments: Part II -Chemical quality A B S T R A C TThe 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 3 rd month, and in AR, there were higher levels of peroxide after 3 rd and 6 th 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.

“…Alencar et al (2009) observaram, avaliando grãos de soja secos armazenados por 180 dias em diferentes condições de temperatura e umidades relativas que, no geral, ocorreram elevação na diferença de cor de grãos durante o armazenamento, com aumento mais acentuado à medida que aumentou o teor de água e a temperatura dos grãos aumentavam. Tal escurecimento nos grãos de soja sugere que houve a deterioração dos grãos armazenados.…”

R E S U M ONeste trabalho avaliou-se a estabilidade de grãos residuais de urucum acondicionados em embalagens flexíveis laminadas durante 90 dias de armazenamento em condições controladas de temperatura (25 e 40 °C) e umidades relativas (55 e 83%). As amostras foram analisadas a cada 15 dias, por meio da análise do teor de água, atividade de água, pH, acidez titulável, cor (luminosidade, intensidade de vermelho e intensidade de amarelo) proteína bruta, amido e bixina. Observou-se, no decorrer dos tempos de armazenamento, que as embalagens não evitaram a absorção de água acarretando em aumentos do teor de água (42,62; 43,06; 41,78 e 42,90%), atividade de água (6,39; 6,94; 5,97 e 6,94%), acidez titulável (12,28; 13,79; 9,09 e 13,79%) e luminosidade (4,48; 12,18; 4,73; 4,91%) e ocorreram reduções na intensidade de vermelho (8,19; 7,77; 4,66 e 7,93%), pH (9,21; 8,56; 12,44 e 18,12) e bixina (51,72; 56,32; 57,47 e 55,17%) respectivamente, para as seguintes combinações de umidades relativas e temperaturas (55% e 25 ou 40 °C; 85% e 25 ou 40 °C). Storage of waste grains of annatto under controlled atmosphere A B S T R A C TThis study evaluated the stability of residual annatto beans packed in flexible laminated packaging during 90 days of storage under controlled temperature conditions (25 and 40 °C) and relative humidity (55 to 83%). Samples were analysed every 15 days, for analyzing the moisture content, water activity, pH, acidity, color (brightness, redness and yellowness), protein, starch and bixin. It was observed during the storage time of the packaging did not prevent the absorption of water leading to increases in moisture content (42.62; 43.06; 41.78 and 42.90%), water activity (6.39; 6.94; 5.97 and 6.94%), titratable acidity (12.28; 13.79; 13.79 and 9.09%), and brightness (4.48; 12.18; 4.73 and 4.91%) occurred reductions in redness (8.19; 7.77; 4.66 and 7.93%), pH (9.21; 8.56; 12.44 and 18.12%) and bixin (51.72; 56.32; 57.47 and 55.17%), respectively, for the following combinations of relative humidity and temperature (55% and 25 or 40 °C, 85% and 25 or 40 °C).

“…Zucareli et al (2015) found remarkable reduction in physiological quality of carioca beans stored under ambient conditions (without control of temperature and humidity) compared to storage in controlled environment. Alencar et al (2009) noticed that grains stored at temperatures of 30 and 40 °C have more intense respiration, although humidity also influences grains metabolism. High water content is the main cause of physiological quality decrease of stored seeds (Goldfarb & Queiroga, 2013), what, according to Alencar et al (2009) leads to qualitative deterioration process under high temperatures.…”

Stored beans have active metabolism and respiration may cause significant quality losses. Therefore, some care is necessary during this period, aiming at maintaining the physiological quality of seeds, minimizing their deterioration and reducing their germinative power. Seed quality during storage may be influenced by environmental factors and the interaction of genotypes with the environment. The objective was to evaluate the germination and vigor of bean seeds after 90-days storage under different temperature conditions. The experiment was conducted under a completely randomized design, with four replications, in 3 × 2 factorial scheme, considering three storage temperatures (10 °C, 20 °C and 30 °C) and two storage times (0 and 90 days). For potential evaluation, the following characteristics were considered: moisture content, thousand seed mass, germination, electrical conductivity, accelerated aging and cold test. Numerical data were submitted variance analysis with averages compared by means test at 5% of significance. Results showed that storage temperature conditions directly affect physiological quality of bean seeds. Temperature of 10 °C provided better seed conservation whereas temperature of 30 °C promoted higher deterioration and reduced vigor.
