摘要:本文主要研究了多谷物粉、原辅料和操作工艺条件对硬质面包感官品质及比容的影响,确定了多谷物硬质面包的制作配方与主要工艺参数。结果表明,单一添加燕麦粉、荞麦粉、亚麻籽粉或麦麸粉制作硬质面包时,其添加量分别以6%~8%、6%、4%、4%较为适宜。而在多谷物硬质面包的制作中,其最佳制作配方(焙烤比%)为:高筋粉86,燕麦粉6,荞麦粉4,亚麻籽粉4,谷朊粉2,酵母2.5,面包改良剂1,砂糖5,盐1,奶油6,水50。烘焙温度上火200℃、下火180℃,烘烤时间20min。此时,多谷物硬质面包口感最好,有回甜,面包皮色、皮质相对较好,内部组织柔软细密。采用质构仪测得,多谷物硬质面包皮的硬度为1097.3g,面包瓤芯的硬度为738.0g。21528

Study on the development of multi-grain hard bread
Abstract:First,this paper studies the multi-grain flour, the impact of raw materials and operating conditions on the sensory quality of hard bread and hematocrit,determine the production of rigid multi-grain bread recipe with the main process this paper.The results showed that ,when you add Oat flour to make bread, add the amount to 6% is more appropriate. when you add buckwheat flour to make bread, add the amount to 6% is more appropriate. when you add flaxseed flour to make bread, add the amount to 4% is more appropriate. when you add wheat bran flour to make bread, add the amount to 4% is more appropriate. The result showed that in the multi-grain bread production of rigid,the best production formula(baked ratio%) of high-gluten flour 210, flaxseed powder 10, buckwheat flour 15,rye flour 15, yeast 5, salt 2, bread improver 2, gluten 5, sugar 10, butter 12, water 135.The main parameters of the production process for bread:kneading time 6-10min,basic fermentation time 60min, proofing time 45min,the best baking temperature is 200℃ upwardly,180℃ below,the best baking time is 20 minute.At this point, multi-grain hard bread taste best,there are back sweet, crust color, the cortex is relatively good, soft and fine internal organization. Measured using the texture analyzer, multi-grain hard crust hardness 1097.3g, crumb hardness of the core 738.0g.
