Black bean seeds were dehulled both manually and mechanically and the flours obtained from the dehulled seeds were compared with flour milled from undehulled seeds. The flours obtained were evaluated for proximate composition, physical and pasting properties. Anti-nutritional factors in the flours were also determined. The flours were then used to prepare steamed bean cake (“Moinmoin”) which was evaluated for sensory parameters of appearance, taste, aroma, texture and overall acceptability. Dehulling produced significant effects (p 0.05 and p > 0.01) prepared from dehulled flours, but there was significant difference (p < 0.05) at both levels in most sensory parameters between samples from dehulled seeds and undehulled seeds except for aroma.展开更多

Total phenols, flavonoids and free radical scavenging capacity were determined by colorimetric methods. Furthermore, qualitative flavonoid characterization was performed via HPLC diode array. The acetic acid extract contained 73.4 ± 7 mg/g of sample expressed as gallic acid equivalents (GAE), and 41.3 ± 4 mg/g as catechin equivalents (CE). The acetic acid extract (at 1 mg/mL) showed over 89% efficiency to scavenge the 1,1 diphenyl-2-picrylhydrazil (DPPH) radical (EC50 = 6.13 mg extract/mg standard). Gallic acid, delphinidin-3-glycoside, petunidinglycoside, petunidin, malvidin-3-glycoside, myricetin-glycoside, quercitin-glycoside, saponin (β-g), and 3-hydroxy-5, 7-megastigmadien-9-one were identified in both extracts. Additionally, kaempferol-3-glycoside was found in the acetic acid extract. Sequential acetic acid extractions indicated that the antiradical activity was about 90% in DPPH radical scavenging within the first 8 h of extraction, when compared to a 24 h extraction. In general, acetic acid offered a faster and more efficient approach for the extraction of展开更多
