| 摘 要： | 对长货架期软面包质构的测定方法进行研究.首先选用探头P/2测定面包皮硬度,探头P/6测定面包芯硬度,探头P/0.5测定面包芯硬度及新鲜度.由测定结果的稳定性筛选探头后,应用探头P/0.5测定面包贮存期间质构变化,分析比较测定结果与感官评价结果相关性.实验结果表明:以探头P/0.5所测硬度指标作为面包新鲜度的客观评价值最为科学,每个样品的变异系数为10.76,贮藏期实验中,与面包新鲜度的感官评价结果相关性系数达到0.925 8.

| Abstract: | The methods of determination the texture of a long shelf-life soft bread was investigated.The P/2 probe was cho-sen to test the hardness of the breadcrust,while the P/6 probe was chosen to test the hardness of the bread core.The P/0.5 probe was chosen to test the hardness and the freshness and analyzed the stability of the result.Then the P/2 probe was used to test the texture of the bread during the storage.The test result were analyzed by combined with sensory evaluation which can indicate the bread's fre... |
