Abstract
The components of malt sprouts were effectively separated by manual wi nnowing into acrospires (15.3%), rootlets (40.1%) and husks (43.7%). T he bitter taste was located in the acrospires. Percent recovery of pro tein and fibre was, respectively, 95.2 and 87.2 of malt sprouts. The a crospires were rich in protein (30.3%) and sugars (45.7%) but low in c alcium (1.94 g kg(-1)), fibre content (4.6%) and essential amino acids . They had moderate functional properties, The rootlets were rich in c alcium (19.9 g kg(-1)) and in protein (31.9%), which had a good nutrit ive value (law in phytic acid and polyphenols content). They had a mod erate fibre content (10.7%). Consequently, they had the highest water absorption, oil absorption and emulsification capacities. The rootlets had relatively low foam capacity but the highest foam stability. The husks were rich in fibre content (25%) but moderate in protein content (12.4%), which was rich in essential amino acids. The husks were rela tively low in calcium (11.83 g kg(-1)) and phosphorus (6.53 g kg(-1)) contents and in vitro protein digestibility (68.9%). Their functional properties were influenced by high fibre and moderate protein contents . The first limiting amino acids were sulphur-containing ones in the m alt sprouts, the acrospires and the rootlets, but it was leucine in th e husks.
