竹笋含有丰富的营养成分。为了探讨竹笋粉对面团和面包品质影响，该研究把竹笋粉以不同添加量（0%、3%、5%、7%，m/m）加入到小麦粉中制作成面包，对面团面筋蛋白、面包色泽、感官、质构特性和贮藏性进行测定。结果表明：随着竹笋粉添加量的增加，面团面筋蛋白含量降低，面包硬度和咀嚼性均提高。低剂量竹笋粉的添加（3%~5%）对面团的pH值和面筋含量影响不显著（P>0.05），但添加量为7%时湿面筋含量相对下降了9.87%，影响显著。竹笋粉添加与面包的比容和失水率呈负相关，空白组、添加量3%、5%、7%（m/m）的失水率分别为2.45%、2.09%、2.17%、1.77%，其硬度、胶着性、弹性以及咀嚼性变化显著（P<0.05），对内聚性、回复性影响不显著（P>0.05）。添加竹笋粉（3%~5%）可以提升面包的色泽，使面包具清香风味，但7%的添加量使面包的色泽过深，气味较浓。说明低剂量（3%~5%）的竹笋粉添加制备面包，可提升面包咀嚼感，亮色、丰富其营养成分，还起到延缓面包老化作用。

Bamboo shoots are rich in nutrient. In order to explore the effect of bamboo shoot powder on the quality of dough and bread,different amounts of bamboo shoot powder (0%, 3%, 5%, 7%) were added to wheat flour to make bread, and the dough gluten protein as well as bread color, sensory attributes, texture characteristics and storage stability were investigated in this study. The results showed that with the increase in addition amount of bamboo shoot powder, dough gluten protein decreased, bread hardness and chewiness increased. The addition of low-dose bamboo shoot powder (3%~5%) had insignificant effect on the pH value and gluten content of dough (P>0.05), however, when the addition amount was 7%, the wet gluten content decreased by 9.87%, indicating a significant effect. The addition of bamboo shoot powder was negatively correlated with the specific volume and water loss rate of bread. The water loss rates for the blank group and the groups with bamboo shoot powder added at 3%, 5% and 7% were 2.45%, 2.09%, 2.17% and 1.77% respectively, with significant changes being observed in hardness, adhesiveness, elasticity and chewiness of bread (P<0.05) and insignificant changes in the cohesion and recovery of bread (P>0.05). Adding bamboo shoot powder can enhance the color of bread, and make the bread having a fragrant flavor, but the addition of 7% bamboo shoot powder made the bread color too dark with a stronger smell. Therefore, adding bamboo shoot powder at a low dose (3%~5%) can enhance bread chewiness, brighten the color, enrich its nutrient content, and also delay the aging of bread.
