A Brasilian water bread was formulated with wheat flour (100%), salt (2%), yeast (5%), water (60%), fungal amylase (130 SKB/100g wheat flour), ascorbic acid (0.02%), and polysorbate‐60 (1%). To the formulation was added Lysine.HCl at levels of 0.1, 0.2, 0.3, 0.4, and 0.5% as related to wheat flour in the formulation. The breads (fortified and control) were baked at 220°C for 20 min. The retention of lysine was estimated by measuring the free Lysine·HCl in bread with FDNB. A regression equation was developed relating the input and retention of lysine, which indicated a loss or destruction of 11.3% of added lysine during baking process.
