Physicochemical and sensory characterization of bread produced from different dough formulations by Kluyveromyces lactis

摘要

This study aimed to investigate the potential of Kluyveromyces lactis to be used as baker's yeast in production of lean bread (100% of wheat flour) and sucrose (10%), lactose (10%), or whey (13.35%) supplemented breads. The pH, total titratable acidity, baking loss, specific volume, color parameters, textural, and sensory properties of breads produced by K. lactis were measured and compared with those of breads produced by commercial baker's yeast. Type of yeast and dough formulation had significant influences on pH, specific volume, baking loss, textural parameters, and color parameters of breads. Commercial baker's yeast presented better results than K. lactis in lean bread. The investigated parameters of K. lactis leavened bread were improved with the addition of each ingredient. Whey and lactose added breads leavened by K. lactis had quality characteristics and sensory scores as good as or better than the breads leavened by commercial baker's yeast.
