Table 4.

Results from analysis of the techno-functional properties of bread with inclusion of brewers’ spent grain (BSG) and fermented brewers’ spent grain (FBSG) at source of fibre (SF) and high in fibre (HF) addition levels. BF and WMF represents results obtained from baker’s flour and wholemeal flour breads, respectively. The values shown represent the mean ± the standard deviation. Values which have the same letter in the same row do not differ significantly.
