摘  要:
以云南省蒙自地区甜绿籽、甜光元和甜沙籽3种石榴为材料,利用原子吸收光谱法测定了套袋与未套袋石榴汁中7种金属元素含量。结果表明,石榴汁液中K,Ca,Mg,Cu,Na,Pb和Cr等金属元素的含量均依次降低,其中K含量最高;套袋石榴中金属元素的含量低于未套袋石榴,尤其套袋石榴中Cr,Pb等有害元素的含量明显低于未套袋石榴,差异达显著或极显著水平;不同品种套袋石榴之间或未套袋石榴之间的金属元素含量差别较小。

摘  要:
The seven metal elements in the fruits of 3 pomegranate varieties sweet-luzi,sweet-guangyuan and sweet-shazi in bagged and untreated fruits in Yunnan province were analyzed by the flame atomic absorption spectrometry.The results showed that the metal elements arranged in content order from high to low were K,Ca, Mg,Cu,Na,Pb and Cr.The contents of trace elements(especially) the harmful ones like Cr and Pb in the encased fruits were lower than that of uncased ones,but the metal element contents of different varieties were less likely different.
