包装方式及小麦品种对酒酿馒头贮藏期间淀粉老化的影响

Effects of Packaging Methods and Wheat Varieties on Starch Aging in Wine-brewed Steamed Bread during Storage

  • 摘要: 为探究4 ℃贮藏7 d酒酿馒头内部淀粉老化与包装方式及小麦品种间的关系,以郑麦113、扬麦20、信麦129为原料制作酒酿馒头后进行无包装和密封包装处理,分析其贮藏期内水分、质构特性、淀粉有序性及微观结构、感官品质变化,并以Avrami方程评价其内部淀粉老化趋势。结果表明:直链淀粉含量显著的郑麦113、支链淀粉含量显著的信麦129及扬麦20粗蛋白含量无显著差异。贮藏期内无包装郑麦113及密封包装扬麦20样品硬度增加,无包装扬麦20样品弹性增加,密封包装信麦129样品硬度无显著变化;红外图谱表明(1047/1025)cm−1比值较高的无包装郑麦113与密封包装扬麦20样品内部淀粉均呈现有序性转化;感官及微观结构表明三组无包装样品均开裂且断裂处可见糊化淀粉颗粒;三组密封包装样品外观完整但内部气孔模糊;以硬度指标构建Avrami动力方程表明无包装郑麦113与密封包装扬麦20样品内淀粉老化结晶速率较高。综上,采用信麦129及密封包装处理可有效延缓4 ℃贮藏酒酿馒头内部淀粉老化,有效改善其储运品质。

     

    Abstract: In order to explore the relationship between the internal starch aging of wine-stuffed steamed bread stored at 4 ℃ for 7 days and the packaging form as well as wheat varieties, Zhengmai 113, Yangmai 20, and Xinmai 129 were used as raw materials to make wine-stuffed steamed bread and then treated with unpackaged and sealed packaging. The changes in moisture, texture characteristics, starch order, microstructure, and sensory quality during the storage period were analyzed. The internal starch aging trend was evaluated by the Avrami equation. The results showed that there was no significant difference in crude protein content between Zhengmai 113 with significant amylose content, Xinmai 129 with significant amylopectin content and Yangmai 20. During the storage period, the hardness of unpackaged Zhengmai 113 and sealed packaged Yangmai 20 samples increased, the elasticity of unpackaged Yangmai 20 samples increased, while the hardness of sealed packaged Xinmai 129 samples showed no significant change. The infrared spectra indicated that the internal starch of the unpackaged Zhengmai 113 and the sealed packaged Yangmai 20 samples with a higher ratio of (1047/1025) cm−1 showed an ordered transformation. Sensory and microscopic structures indicated that all three groups of unpackaged samples cracked and gelatinized starch particles could be seen at the fracture sites. The appearance of the three groups of sealed packaged samples was intact, but the internal pores were blurred. The construction of the Avrami dynamic equation based on the hardness index indicates that the starch aging and crystallization rates in the unpackaged Zhengmai 113 and sealed packaged Yangmai 20 samples were relatively high. In conclusion, the use of Xinmai 129 and sealed packaging treatment can effectively delay the aging of starch inside the 4 ℃ stored wine-stuffed steamed buns and effectively improve their storage and transportation quality.
