ABSTRACT Storage is an important issue for ginkgo nuts industry because it is critical to enabling a year-round supply and the next year of cultivation. An investigation into the crude protein content and amino acids profile in ginkgo nuts after different storage times in terms of varieties was carried out in this work. The crude protein content was generally increased during storage while an opposite trend was observed for the concentration of total amino acids. The concentrations of almost all amino acids were more or less decreased except Cys, which was increased 42.13% after 5-month storage, and showed a significant positive correlation with storage time. The effect of storage seemed to be variety-dependent that the variety Tancheng-300 was less prone to fluctuations in amino acids profile amongst the varieties.

银杏果贮藏期间粗蛋白含量和氨基酸组成的变化

摘要 储存是银杏果产业的一个重要问题，因为它对于实现全年供应和下一年的种植至关重要。本工作对不同品种贮藏时间后银杏坚果的粗蛋白含量和氨基酸谱进行了研究。贮藏期间粗蛋白含量普遍增加，而总氨基酸浓度则观察到相反的趋势。除Cys外，几乎所有氨基酸的浓度均有所下降，Cys在贮藏5个月后增加了42.13%，且与贮藏时间呈显着正相关。贮藏的影响似乎与品种有关，因为品种郯城 300 不太容易出现不同品种间氨基酸谱的波动。
