方案详情:
化学合成甜味剂因其低热量和高甜度的特点而成为蔗糖替代品被广泛添加到食品中,乙烯磺胺酸钾、糖精钠、甜蜜素、阿斯巴甜、阿力甜是目前常用的化学合成甜味剂,每种都有其适用范围和添加限量。国标方法GB/T5009.28--2003《食品中糖精钠的测定》、GB/T5009.140--2003《饮料中乙酰磺胺酸钾的测定》仅对其中三种甜味剂提出了检验方法,且针对的样品本底相对简单,文献报道的甜味剂的检验方法多为2-3种甜味剂的液相色谱检测,少有5种甜味剂同时检测的报道。乳饮料作为饮料市场的一个重要品种,深受消费者尤其是青少年消费者的喜爱,由于乳饮料一般含有牛乳和增稠剂,使得样品前处理工作难度加大,同时多种甜味剂复配使用使得检验工作强度加大。为了准确、快速地完成乳饮料中甜味剂的检验工作,为食品安全保障提供技术支持,本实验对样品的前处理及上机测定进行深入研究,以期建立快速测定乳饮料中5种甜味剂的高效液相色谱法。

文献名: Structural, morphological and optical properties of Bi NPs obtained by laser ablation and their selective detection of L-cysteine 作者: Ramon Gabriel Teixeira Rosaa, Celso de Araujo Duartea , Wido Herwig Schreinera, Ney Pereira Mattoso Filhoa, Arandi Ginane Bezerra Jr.b, Andersson Barisonc, Fernanda Maria Marins Ocamposc a Departamento de Física, Universidade Federal do Paraná Centro Politécnico, CP 19044, 81531-990 Curitiba (PR), Brazil b Departamento Acadêmico de Física, Universidade Tecnológica Federal do Paraná, 80230-901 Curitiba (PR), Brazil c Departamento de Química, Universidade Federal do Paraná Centro Politécnico, CP 19081, 81531-990 Curitiba (PR), Brazil 摘要:In the present work we show the results of the investigation of the properties of bismuth nanoparticles (NPs) obtained by the laser ablation in water. The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词:Bismuth; Nanoparticles; Laser ablation; Cysteine
