摘要
在熵权法对马铃薯全粉面条各项品质指标进行综合分析的基础上,采用正交试验优化出不同比例马铃薯全粉面条的基础配方。结果表明,在全粉比例为25%时,食盐0.6%,碱0.4%,水55%,和面时间7min;全粉比例为30%时,食盐1.2%,碱0.4%,水60%,和面时间6min;全粉比例35%时,食盐0.8%,碱0.6%,水65%,和面时间8min;全粉比例为40%时,食盐0.8%,碱0.6%,水72.5%,和面时间5min。在最优条件下,不同比例的全粉面条感官评分除40%外,均在80分以上,面条整体品质较好,其中全粉比例25%时所得面条品质优于其他3种添加比例。
In order to provide a practical foundation for the production of potato noodles,comprehensive analyses of the quality indexes of potato noodles using the entropy-right method were conducted,and the basic formula of different proportions of potato noodles were optimized,based on orthogonal experiments.The results showed that the optimized basic formula of noodles was 0.6% salt,0.4% dietary alkali,55% water and mixed for7 min,when the potato flour was 25%.However,when the potato powder ratio was 30%,the optimized formula was 1.2%salt,0.4%dietary alkali,60% water and mixed for 6 min.When the potato powder ratio was 35%,that was 0.8%salt,0.6% dietary alkali,65% water and mixed for 8 min.When the potato powder ratio increased to 40%,the optimized formula should be0.8% salt,0.6% dietary alkali,72.5% water and mixed for 5 min.The sensory scores of the potato noodles were higher than80 in most groups except that with 40% of potato powder,and the overall quality of the noodles was good under these conditions.The noodles with 25%potato flour recorded the highest quality scores among those groups.
