方案详情:
甜蜜素(环己基氨基磺酸钠)是一种人工合成的非营养型水溶性、高甜度且价格低廉的甜味剂,已广泛应用于食品加工业,但其超量、超范围添加现象严重。目前,由于甜蜜素的安全性尚存争议,因此甜蜜素项目一直是质监部门实施食品质量安全风险监测的重点之一。按照GB 2760-2011的规定,甜蜜素在加工食品中中的允许使用范围不包括白酒,但有些企业为调节口感而违规添加甜蜜素或添加含有甜蜜素的复合调酒剂。

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

植物油中9种抗氧化剂的测定GB5009.32-2016
抗氧化剂是指能防止或延缓食品氧化,提高食品的稳定性和延长贮存期的食品添加剂。GB5009.32-2016《食品安全国家标准 食品中9种抗氧化剂的测定》中采用GPC和C18小柱对食品中9种抗氧化剂进行前处理,该方法回收率低,测试结果不稳定。安谱实验优化了实验方法,用CNW Poly-Sery PSD SPE小柱进行前处理,克服了国标方法的缺点,方法简单,9种抗氧化剂的回收率均在90%以上。
