加工对芙蓉李中微量元素含量的影响

Study on Content of FU-RONG Piums and Its Products by Differ-machining

采用原子吸收分光光度法对芙蓉李及其几种产品的微量元素含量进行了分析测定,结果表明芙蓉李鲜果中Zn、Fe,Mg、Mn含量丰富.加工后芙蓉李制品的微量元素含量普遍比鲜果高,其主要原因是加工后芙蓉李制品的水分降低.但是加工制品的Mg、Mn含量则比鲜果低.加工方法对芙蓉李的微量元素含量的影响比较大.

The contents of trace elements in FU - RONG Piums and its products were detetrninafioned by Z - 8000 atomic absorption spectrometry. It is indicated its rich contain about Mn, Zn, Fe, Mg in FU - RONG Piums. The results obtained indicate that differ- content of trace elements of FU - RONG Piums and its products by differ- machining. General trace elements of product higher than fresh fruit, because water evaporate for process. FU - RONG Piums＇ s trace elements value can make the exaltation for process. Bet the deal of Mg, Mn of products lower than fresh fruit for process. The influence of processing method is big to contents of trace elements in FU - RONG Piums.
