The purpose of this study was to investigate the quality characteristics of steamed bread using mixed flour containing bamboo leaf and lotus leaf powders. Properties of the steamed breads were tested by colorimeter, water activity, rheometer, SEM, and sensory tests. The L values and a values were higher in steamed bread with bamboo leaf powder. On the other hand, the b values of streamed bread with bamboo leaf powder were lower than lotus leaf powder. During storage, the hardness of steamed bread with bamboo leaf and lotus leaf powders increased control. Furthermore, steamed bread with lotus leaf powder showed hardness than bamboo leaf powder. The springiness of all steamed breads decreased with storage , and steamed breads with bamboo leaf powder showed lower values than lotus leaf powder. The cohesiveness of the control was the highest, and all samples showed significant differences each other. The gumminess of the control was higher than steamed bread with bamboo leaf and lotus leaf powders. Moreover, longer storage time yielded higher gumminess. control relatively smoother surface than that of 1% bamboo leaf powder. The steamed bread with lotus leaf powder had a rougher surface than bamboo leaf powder. sensory characteristics of steamed bread, green color of the samples with bamboo leaf powder was darker than lotus leaf powder. Leaf odor was similar throughout. Freshness of steamed bread containing 1% bamboo leaf powder the highest. The overall acceptability of consumer acceptance was the control, followed by steamed bread containing 1% lotus leaf powder.

The purpose of this study was to investigate the rheological characteristics of medium wheat flour mixed with bamboo leaf and lotus leaf powders. Rheological properties of the mixed flours were tested based on falling number, color, RVA, farinogram, and rheofermentometer analyses. Falling numbers increased with addition of bamboo leaf and lotus leaf powders. The L values of all mixed flours were less than that of control. The 1% mixed flour sample containing bamboo leaf and lotus leaf powders was not significantly different from 3% mixed flour. The a values of the mixed flour decreased as bamboo and lotus powders increased, whereas b values increased. Addition of bamboo leaf and lotus leaf powders to flour reduced peak viscosity, holding strength, and final viscosity. The set back values of mixed wheat flour containing bamboo leaf powder were lower than those of mixed wheat flour containing lotus leaf powder, suggesting that bamboo leaf powder suppressed retrogradation of flour compared to lotus leaf powder. In the farinogram, the water absorption and consistency of the flours containing bamboo and lotus leaf powders increased, whereas development time and stability decreased. The fermentation time of dough with lotus leaf powder was less than that of dough with bamboo leaf powder.
