Propriedades físicas e químicas de feijão comum preto, cultivar Iapar 44, após envelhecimento acelerado

Abstract: 165Propriedades físicas e químicas do feijão, Ribeiro, Priudêncio-Junqueira e Miaguy. Londrina. Caixa Postal 6001, 3. Departamento de Bioquímica, Caixa Postal 6001,. * A quem a correspondência deve ser enviada. -INTRODUÇÃOEm países em desenvolvimento, os feijões são uma importante fonte de proteínas, calorias e outros nutrientes [18]. Entretanto, quando armazenados em condições de altas temperaturas e umidades relativas, comuns em países tropicais como o Brasil, eles se tornam endurecidos, ou seja, podem de… Show more

“…This result has also been observed by other authors (Hentges et al, 1991;Ribeiro et al, 2005). Moreover, the low protein solubility found in beans is due to a secondary structure of the beta-sheet protein found in this leguminous species, which becomes more insoluble when heat is applied (Carbonaro et al, 2008); it may also be associated with the production of insoluble aggregates during storage.…”

“…However, a decrease in the lipid content of stored grains was also observed by other authors (Sawazaki et al, 1985;Ribeiro et al, 2005) and may be related to lipid oxidation, which generates products with higher solubility that are not quantified by the methodology applied in this analysis. The present study recorded a moderate decrease in the lipid content during storage, most likely as a result of fatty acid hydrolysis, which produces acidity and may be associated with the observed pH decrease.…”

“…The results of the electrical conductivity test can be affected by variables in the methodology, and also other factors, such as genotype (SHORT;LACY, 1976;PANOBIANCO;VIEIRA, 1996;VIEIRA et al, 1996), seed water content (LOEFFLER et al, 1988;VIEIRA et al, 2002) and the stage of seed development (STYER;CANTLIFFE, 1983;POWELL, 1986) among others VIEIRA, 2009). More recent studies showed that the storage conditions, principally low temperatures (10º C), can compromise the reliability of the results, as has been observed in the seeds of soybean (VIEIRA et al, 2001(VIEIRA et al, , 2008PANOBIANCO;VIEIRA, 2007;FESSEL et al, 2010) and peas (PANOBIANCO, et al, 2007).…”

“…Acredita-se que a maior preocupação em utilizar a água por conta da qualidade sensorial possa estar associada às UPR de porte 2 e 3 pela realização de compras em maiores volumes, que pode resultar em um maior tempo de estoque e, possivelmente, perda de atributos sensoriais com a diminuição de umidade do grão 33 .…”
