结果表明，常温下黄皮果实贮藏期短，常温贮藏3 d后，好果率低于75%；低温能明显延长果实的贮藏期，延缓果实的糖、酸和VC含量的下降；在2-12 ℃间，贮藏温度越低，保鲜效果越好，适宜的贮藏温度为2-4 ℃；采用MAP保鲜技术能延缓果实品质的下降，在2-4 ℃下大鸡心黄皮MAP保鲜的适宜条件是采用0.025 mm的PE膜包装，装果量为5.4 kg·m-2。

Results:The cell aggregations had differences in shape as well as size, flavone content, enzyme activities, growth speed and so forth. The flavone content of the smallest cell aggregation was approximately twice compared to the larger ones, and its malonaldehyde content, the phenylalanine ammonialyase and peroxide enzyme activities and recultivate curve presented the same change tendency.

结果：不同的细胞聚集体在形态大小、黄酮含量、酶的活性、生长速度等方面均存在着差异，其中颗粒最小的细胞聚集体黄酮含量约为颗粒较大的细胞聚集体的2倍，并且其丙二醛含量、苯丙氨酸解氨酶及过氧化物酶的活性及再培养曲线均具有相同的变化趋势。

The experimental results suggested that there were some rules during the fermentation as follows: pit temperature increased rapidly and then dropped at the beginning of the fermentation and kept stable eventually at 20～22 ℃; there was slight change in yellow water pH value at first and then pH value decreased gradually in middle fermentation stage and finally kept stable; the change rules of total acids of yellow water were opposite to pH change rules; the reducing sugar of yellow water increased at first and then dropped and kept stable eventually; there was almost no change in alcohol content of yellow water in prior fermentation period, and then it increased rapidly and dropped slowly and finally kept stable; gas production rate was as high as 550 L/d within the first week in fermentation and then dropped undulatingly and changed to zero or even negative gas production rate.
