  • Received Date: December 29, 2014
  • In this study,Lactobacillus plantarum( LP) and Lactobacillus fermentum( LF) were used to ferment buckwheat dough to make sourdough bread.The effect of lactic acid bacteria( LAB) fermentation for buckwheat on the antioxidant and baking properties were explored. The results indicated: LAB- fermented sourdough had lower p H and higher TTA,LAB fermentation can enhance the antioxidant activity of buckwheat sourdough. The bread made from LP fermented buckwheat sourdough showed an increase in total phenolic content by 21.3%,DPPH and ABTS radical- scavenging activity were 3 and 1.2 times that of unfermented buckwheat dough. Adding lactic acid bacteria improved the effect of heat processing on oxidation of active substances,total phenolic content of LP and LF bread were reduced by 48.5% and 51.6%,while DPPH and ABTS radical- scavenging activity were reduced by41.2%,54.8% and 69.0%,68.4%,respectively.LAB fermentation also significantly improved the texture of bread,the hardness of LF fermented bread were decreased by 25.5%. When fermented buckwheat sourdough was added,sensory quality of sourdough breads were more acceptable than those of unfermented buckwheat bread.
