冷冻面团原料小麦粉的筛选及各指标的相关性分析

Screening of wheat flour for frozen dough and correlation analysis of each indicators

  • 摘要: 本实验选取了六种不同商业高筋小麦粉,采用粉质仪、拉伸仪和糊化仪对其进行基础成分和流变学特性的测定,并对所得指标数据进行相关性分析,同时对应用各小麦粉制作的冷冻面团的质构特性进行测定分析,筛选出北大荒高筋小麦粉适于制作冷冻面团。各特性指标进行相关性分析结果显示,吸水率与水分含量、蛋白质含量、最大拉伸阻力呈显著正相关(p<0.05),相关系数为0.849、0.789、0.828;形成时间与湿面筋含量、最大拉伸比例呈显著正相关(p<0.05),相关系数为0.900、0.885;形成时间与拉伸阻力、最大拉伸阻力、拉伸比例呈极显著正相关(p<0.01),相关系数为0.986、0.958、0.933;水分含量与最大拉伸阴力呈显著正相关(p<0.05),相关系数达到0.828;蛋白质含量与拉伸阻力、最大拉伸阻力、拉伸比例呈显著正相关(p<0.01),相关系数为0.986、0.958、0.933。 

     

    Abstract: After determination of the basic ingredient and the rheological properties of the six kinds of commercial wheat flour,and analysis the correlation of each indicators,texture properties analyzer was used to measure the characteristics of frozen dough,finally Beidahuang high gluten wheat flour was chosen to product frozen dough. The correlation analysis results showed that the water absorption was positive correlation with water conten and protein content and maximum tensile resistance(p<0.05) and correlation coefficient respectively was 0.849,0.789,0.828. Formation time was positive correlation with wet gluten and maximum tensile ratio( p < 0.05) and correlation coefficient respectively was 0.900, 0.885. Formation time was extremely positive correlation with tensile resistance and maximum tensile resistance and tensile ratio(p<0.01),correlation coefficient was 0.986,0.958,0.933. Water content was positive correlation with maximum tensile resistance(p<0.05) and correlation coefficient was 0.828. Protein content was extremely positive correlation with tensile resistance and maximum tensile resistance and tensile ratio(p<0.01) and correlation coefficient was 0.986,0.958,0.933.
