Description
Yellow pea (Pisum sativum L.) flour fortified gluten-free (GF) bread formulation was optimized by response surface methodology (RSM) and the final product was evaluated for shelf life and sensory acceptability. A second-order model was fitted to the precooking temperature of pea flour (PTPF), water level, and proof time as the factors. Higher PTPF and lower proof time significantly (P<0.05) reduced the brightness of bread crumb. Crumb firmness was influenced by the PTPF, water level and proof time. The optimized parameters for PTPF, water level, and proof time were 156.9 °C, 523.8 g, and 18.0 min, respectively. The optimized bread had a brightness (L* value), specific volume, crumb firmness, and cell diameter of 68.2, 2.6 ml/g, 174.2 gf, and 3.81 mm, respectively. The optimized GF bread had longer shelf-life, but had significantly (P<0.05) lower acceptance scores, than the commercial premix bread product.
