- Abstract
Seeds from two commercial bean varieties were cooked and stored for different times and analysed for chemical composition and in vitro starch digestibility. Parallel portions of cooked seeds were dried at 55°C, milled and stored as flours. In general, protein and ash contents in both samples did not change with storage time, but statistical differences were shown between the two varieties (p < 0.05). Available starch (AS) contents in flours from the 'negro' variety did not change (p < 0.05) with storage time and, in general, were higher than in 'flor de mayo' samples, whose AS levels decreased during storage. The lower AS in 'flor de mayo' flour could be the consequence of formation of resistant starch due to retrogradation.... (More)
Seeds from two commercial bean varieties were cooked and stored for different times and analysed for chemical composition and in vitro starch digestibility. Parallel portions of cooked seeds were dried at 55°C, milled and stored as flours. In general, protein and ash contents in both samples did not change with storage time, but statistical differences were shown between the two varieties (p < 0.05). Available starch (AS) contents in flours from the 'negro' variety did not change (p < 0.05) with storage time and, in general, were higher than in 'flor de mayo' samples, whose AS levels decreased during storage. The lower AS in 'flor de mayo' flour could be the consequence of formation of resistant starch due to retrogradation. Samples of whole 'negro' seeds did not show differences in AS content at 0, 24 and 48 h of storage compared with the corresponding flours, but at 72 and 96 h the AS increased in the whole samples. 'Flor de mayo' showed a similar pattern in flour and whole samples, with slightly higher values in the whole seeds. In general, total resistant starch (RS) content in the two varieties was higher in the flours than in 'whole' seeds, a fact that is not easy to explain at present. 'Negro' flour presented an RS content around 65.0 g kg-1, and approximately 55.0 g kg-1 was recorded in 'flor de mayo', with slight changes when storage time increased. Whole 'flor de mayo' showed significant levels of the retrograded portion of resistant starch (RRS), which did not change with storage time (p < 0.05). However, values were lower than in the flours. A pattern similar to that of the 'negro' variety was obtained for 'flor de mayo', since the flour exhibited higher amounts of RRS; however, in this variety, the RRS content in 'whole' samples decreased after prolonged storage. Flours presented higher amylolysis rates than whole samples, and the ease of digestion increased with storage time.
