摘要: 近年来我国饼干行业发展迅速,酥性饼干以其酥性、糖油比例适中等特点深受各年龄层人们的喜欢。本文针对影响酥性饼干的原辅料成分进行了研究,以面粉、薏米粉、荞麦颗粒为主要原料,在单因素试验的基础上,以感官指标和酥脆性为评定指标,采用正交试验优化薏荞酥性饼干的配方。实验结果表明,薏荞酥性饼干的最佳配方是面粉100%、薏米粉20%、荞麦颗粒10%、植物油32%、小苏打1.6%、水3%,糖霜30%、蛋液17%、全脂奶粉4.6%、精盐0.3%。此时饼干的品质最优,不仅具有良好的酥脆性,而且具有独特的荞麦清香。61991

Study on the crafts of barley and buckwheat in biscuit
Abstract: Targeting the re-examine production process of formulation Barley and buckwheat biscuit,our research added Barley powder and buckwheat granule based on the original ingredients.We established four main factors(Barley powder, shortening, baking soda and water) of the biscuits production through the preliminary experiments. By single factor and orthogonal experiments, and sensory evaluation, determination of color, texture detection, we determined the best formulation of Barley and buckwheat biscuit are: barley powder and wheat flour mass ratio of 2: 8 (100% of the total flour ), 32% of shortening, 1.6% of baking soda, 3% of water, and the remaining percentage of the raw materials accounted for the total amount of buckwheat flour particles were 10%, 30% of icing sugar, 17% of edd, 4.6% of whole milk powder, 0.3% of salt.
