摘  要：
为全面了解绿豆皮、红小豆皮和黑豆皮的18种元素含量,充分开发利用豆皮资源,提高豆类加工产品的附加值,用元素分析(elemental analyzer,EA)仪和电感耦合等离子体发射光谱(inductively coupled plasmaatomic emission spectrometer,ICP-AES)仪测定了3种豆皮的N、C、S、Ca、Mg、K、P、Na、B、Ba、Co、Cr、Cu、Fe、Mn、Ni、Zn和Sr元素含量。结果表明,EA仪测定豆皮中N、C和S方法检出限为32~96μg/g,回收率为97%~115%,相对标准偏差为0.20%~2.63%(n=5);ICP-AES测定豆皮中Ca、Mg、K、P、Na、B、Ba、Co、Cr、Cu、Fe、Mn、N i、Zn和S r元素方法检出限为0.02~152μg/g,回收率为84%~11 8%,相对标准偏差为0.44%~4.46%(n=5)。黄豆标准物N、Mg、P、B、Ba、Co、Cr、Mn、Ni、Zn和Sr元素测定值在推荐范围内,S、Ca、K、Na、Cu和Fe元素测定值接近推荐值。分析方法快速、简便,达到了应用的要求。

摘  要：
In order to fully develop and utilize bean coat resources and increase the added value of processed bean products, the contents of N, C, S, Ca, Mg, K, P, Na, B, Ba, Co, Cr, Cu, Fe, Mn, Ni, Zn and Sr in the seed coats of mung bean, adzuki bean and black soybean were determined by elemental analyzer(EA) and inductively coupled plasma-atomic emission spectrometer(ICP-AES). The limits of detection(LODs) for the elemen ts N, C and S with an elemental analyzer were 32–96 μg/g, and recovery rates were 97%–115% with relat ive standard deviations(RSDs) of 0.20%–2.63%(n = 5). The LODs for the elements Ca, Mg, K, P, Na, B, Ba, Co, Cr, Cu, Fe, Mn, Ni, Zn and Sr with ICP-AES were between 0.02 and 152 μg/g, and recover y rates were in the range of 84%–118% with R SDs of 0.44%–4.46%(n = 5). The soybean standard substance was measured using the developed methods, and the results indicated that the contents of N, Mg, P, B, Ba, Co, Cr, Mn, Ni, Zn and Sr were within the recommended range, while the contents of S, Ca, K, Na, Cu and Fe were close to the recommended values. The analytical methods proved to be rapid and simple and can be applied for elemental analysis.
