  • The influence of the flour types, including bread flour and cake flour on sourdough preparation was investigated. As starters, mixed probiotic microorganisms, including Bifidobacterium longum KCTC 5734, Enterococcus faecium KCTC 13410, and Lactobacillus acidophilus KCTC 3925, or Saccharomyces cerevisiae fermented separately for 15h at $30^{\circ}C$, were combined and then fermented for 10h at $30^{\circ}C$. The combined process with cake flour showed a 100-fold and two-fold increase in [$H^+$] and titratable acidity, respectively. This was also reflected in the viable cell counts and lactate concentration in sourdough. These results show that bread flour and cake flour may be useful for the production of sourdough.

  • In this study the Theological properties between C1-treated soft wheat flour and untreated soft wheat flour was determined. Chlorine treatment lowered pH of the flour in a linear fashion. Water absorption and dough stability was high in proportion to the increase of treatment level but mechanical tolerance index was reduced by each increment of chlorine. The valorimeter value did not exhibit reproducible trend on treatment of chlorine. In general, resistance(BU), resistance to extension and maximum viscosity(BU) were highest in control group; lowest in 1 oz./cwt. flour and tended to rise in 2 oz./cwt. flour when it fermented in chamber for 90 min and 135 min. The maximum viscosity was highest (1,160BU) in 4 oz./cwt. flour and temperature at maximum viscosity tended to rise gradually in proportion to the increase of treated level.

  • This study was to investigate the flour quality and bread making condition required for Korean-style steamed bread, using 5 commercial wheat flours (protein content from 8.2 to 12.5%), They were compared in making steamed bread (SB) and baked roll bread (BRB). Straight dough method was used and the temperatures of dough and fermentation were controlled at 26$^{\circ}C$ and 32$^{\circ}C$, respectively. The first fermentation was conducted at various times (0, 20, 40 and 60 min) and then forty min of proofing (2nd fermentation) was used for all bread dough. As the 1st fermentation time increased, volumes of both SB and BRB increased 4.3 ~8.7% and 27~40%, respectively, but the SB flattened and the total bread scores of SB decreased due to the lack of smoothness and shininess of the bread surface and poor grain. Contrary to that, the total bread scores of BRB increased. SB made from the flour containing 10.5% of protein, was of its highest quality: relatively high volume, smooth, semiglossy and white surface, good texture, followed by SB made from flours containing 10.9%, 9.5%, 12.5%, and 8.2% of protein content, respectively These results suggest that the 1st fermentation process was not needed for SB making. Total bread scores of SB were better correlated with farinograph dough stability than protein contents and volumes of SB were correlated with farinograph development time. Therefore, in steamed bread making, flour dough rheology is important as well as protein content.
