Embalagem a vácuo: efeito no escurecimento e endurecimento do feijão durante o armazenamento

Abstract: RESUMO A infl uência do uso de embalagem a vácuo no controle do escurecimento e endurecimento do tegumento foi avaliada em feijões da cv. 'Pérola'. Os feijões após secos foram submetidos

“…There was an increase in the metabolic rate with storage time, as shown by the loss of dry matter (Figure 3), resulting in a darkening of the grains. Color variables were, therefore, directly related to loss of quality (Lima et al 2014). Furthermore, the fact that the initial color of the grains was altered as a result of tegumentary darkening can also be confirmed by the chroma index, given that this parameter reveals the extent to which the saturation of the characteristic grain colors is reduced, resulting in more greyish shades, as proposed by McGuire (1992) (Figure 5).…”

“…Therefore, the lower grain water contents during the storage, the greater the physical-chemical and microbiological qualities. The grains should be kept at a moisture content of 10 to 12% for six to eight months storage, with the lowest values being indicated for species such as soybean, crambe, and peanuts where lipid reserves predominate (Surki et al, 2012;Lima et al, 2014;Bessa et al, 2015). Regarding the results in Table 3, there was a reduction in grain water contents over storage time, and the apparent specific mass decreased from 880.04 to 649.33 (kg m -3 ) regardless of the storage form.…”

“…No comércio de grãos de feijão, atributos qualitativos como menor tempo para o cozimento, alta capacidade de hidratação e qualidade proteica são preferidos pelos consumidores (BURATTO et al, 2009;COELHO et al, 2008;LEMOS, 2010;MINGOTTE et al, 2013;OLIVEIRA et al, 2013;PERINA et al, 2010;RAMOS JUNIOR et al, 2005a). No entanto, durante o seu armazenamento alguns destes atributos são alterados, e os prejuízos são expressos principalmente pelo aumento do tempo de cozimento e escurecimento do tegumento, o que leva perda de valor comercial (LIMA et al, 2014).…”
