为研究不同冷藏温度的南疆骏枣品质组分信息变化，本文以南疆骏枣为研究对象，对骏枣样品采集一维近红外光谱，用2D-shige二维相关分析软件对所采集的近红外光谱进行二维相关分析。25 ℃、1 ℃、0 ℃、-1 ℃温度骏枣的同步谱自动峰数目分别为6个、5个、4个、3个。常温储存的骏枣最强峰7 173 cm-1表明总酸成分含量变化最大；1 ℃冷藏温度的蛋白质和维生素含量几乎无变化；0 ℃冷藏温度最强峰7 081 cm-1表明总酸成分含量变化最大；-1 ℃冷藏温度的3个自动峰表明总酸、总糖、水分的含量发生变化。结果表明：不同冷藏温度骏枣的二维相关光谱中自动峰的位置与数目不同，说明对冷藏温度微扰敏感的骏枣组分及各组分变化程度不同；与常温25 ℃储存相比，1 ℃、0 ℃、-1 ℃温度对南疆骏枣的冷藏效果较显著，这很好的证明了冷藏对保持骏枣的品质有重要的作用；获得了南疆骏枣的最佳冷藏温度为0 ℃。

In the present study, the changes in the quality components of Jun jujube samples obtained from Southern Xinjiang after storage at different temperatures were analyzed by one-dimensional near infrared spectral analysis. Then, a two-dimensional correlation analysis of the collected infrared spectra was conducted using 2D-shige software. The numbers of automatically numbered peaks in the synchronous spectra of Jun jujube stored at 25 ℃, 1 ℃, 0 ℃, and -1 ℃ were six, five, four, and three, respectively. The strongest band detected in Jun jujube stored at room temperature (7,173 cm-1) suggested that the largest change in total acid content occurred at this temperature. The protein and vitamin content was largely unchanged after storage at 1 ℃. The strongest band detected in Jun jujube stored at 0 ℃ (at 7,081 cm-1) indicated that the largest change in total acid content occurred at this temperature. The three automatic peaks detected in Jun jujube stored at -1°C indicated that the total acid, total sugar, water content changed after storage at this temperature. The analysis results showed that the position and number of automatic peaks detected by two-dimensional correlation spectroscopy (2DCOS) in Jun jujube stored at different temperatures were different, indicating that the changes in the temperature-sensitive components of Jun jujube were different. Compared to Jun jujube stored at a normal temperature of 25 ℃, Jun jujube stored at 1 ℃, 0 ℃, and -1 ℃ showed significant cold storage effects. These results show that cold storage plays an important role in maintaining the quality of Jun jujube and that the best cold storage temperature for Jun jujube from Southern Xinjiang is 0 ℃.
