探讨了生鲜湿面条在储藏条件为常温(25℃)覆膜保鲜、冷藏(4℃)覆膜保鲜、冷藏(4℃)不覆膜保鲜下品质随储藏时间的变化。结果表明:水分、横向弛豫时间犜2、酸度、质构、色泽等各指标之间具有显著相关性。面条水分随储藏时间的延长逐渐降低,冷藏储藏下降低的幅度较大;面条的弛豫时间犜21及犜22随储藏时间呈下降趋势;冷藏储藏面条酸度随储藏时间的延长而降低,其他两种储藏条件下,酸度则升高;色泽方面,面条白度均逐渐降低,其中冷藏储藏白度降低的幅度最小,常温储藏白度降低的幅度最大;质构方面,硬度随储藏时间延长而升高,弹性及内聚性随储藏时间延长而降低。
探討瞭生鮮濕麵條在儲藏條件為常溫(25℃)覆膜保鮮、冷藏(4℃)覆膜保鮮、冷藏(4℃)不覆膜保鮮下品質隨儲藏時間的變化。結果錶明:水分、橫嚮弛豫時間犜2、痠度、質構、色澤等各指標之間具有顯著相關性。麵條水分隨儲藏時間的延長逐漸降低,冷藏儲藏下降低的幅度較大;麵條的弛豫時間犜21及犜22隨儲藏時間呈下降趨勢;冷藏儲藏麵條痠度隨儲藏時間的延長而降低,其他兩種儲藏條件下,痠度則升高;色澤方麵,麵條白度均逐漸降低,其中冷藏儲藏白度降低的幅度最小,常溫儲藏白度降低的幅度最大;質構方麵,硬度隨儲藏時間延長而升高,彈性及內聚性隨儲藏時間延長而降低。

The effects of storage conditions including room temperature film preservation(25℃),low temperature film preser-vation(4℃)and cold storage(4℃)with storage time on fresh wet noodle quality were investigated.The results showed thatthere was significant correlation among moisture content,transverse relaxation time T2,acidity,TPA and color.The moisturecontent of noodle decreased with storage time increasing,which markedly reduced during cold storage;the relaxation time T21and T22 also decreased with storage time increasing;the acidity value of noodle during cold storage decreased with storage timeincreasing,while the opposite results were shown under other two conditions;for color,noodles whiteness were gradually re-duced with storage time increasing,the decrease amplitude of noodles whiteness during cold storage was the smallest,and thatduring room temperature storage was the largest;the TPA test implied that the flexibility and cohesiveness decreased with stor-age time increasing,while the opposite results was shown in hardness.
