Enrichment of Egyptian 'Balady' bread. Part 2. Nutritional values and biological evaluation of enrichment with decorticated cracked broadbeans flour (Vicia faba L.).
Decorticated cracked broadbeans flour (DCBF) was used to replace 5%, 10%, 15% and 20% of the wheat flour (WF) in the Egyptian 'Balady' bread. The nutrient composition of DCBF, WF, wheat bread, and DCBF-fortified bread was studied. When DCBF fortification was increased from 0 to 20%, there was an increase of 36% in protein, 18% in fat, 123% in calcium, 52% in phosphorus and 40% in iron contents. DCBF contained greater amounts [g/16 g N] of lysine and histidine compared to WF. All essential amino acids increased when DCBF was substituted for WF from 0 to 20%, except methionine, which decreased. The biological quality of the breads was investigated. The protein efficiency ratio for 10%. DCBF bread (1.60) was found to be significantly greater (P < 0.05) than that of 5%-DCBF bread (1.48) and wheat bread (1.17).
