description | Abstract Liquid chromatography coupled to Orbitrap high resolution mass spectrometry was shown to be an adequate technique to control the adulteration of whey protein food supplements with prohibited substances, not declared on the labels. An extraction method combined with an instrumental analysis that allowed for the determination of 105 substances in whey protein food supplements, was established. The pre-treatment of the samples consisted of protein precipitation and solid-phase extraction using weak cation exchange functionalized polymeric sorbent cartridges. The samples were directly analyzed by LC-Orbitrap-HRMS. The selectivity, limit of detection, repeatability, recovery, carryover and matrix effect were estimated as the validation parameters. The repeatability obtained was 96.19% and the recovery 83.80%, but carryover and the matrix effect were not observed. The present method was successfully applied to the analysis of commercial samples, verifying adulteration by diuretics (conivaptan and politiazide) and a stimulant (benfluorex) in seven of the eleven brands evaluated.
Resumo A cromatografia líquida acoplada à espectrometria de massas de alta resolução do tipo Orbitrap demonstrou ser uma técnica adequada para o controle de adulteração de substâncias proibidas não declaradas nos rótulos de suplementos proteicos derivados de soro de leite. Foi estabelecido um método de extração combinado a uma análise instrumental que permitiu a determinação de 105 substâncias em suplemento proteico derivado de soro de leite. O pré-tratamento das amostras consistiu na precipitação de proteínas e na extração em fase sólida, utilizando-se cartuchos com sorventes poliméricos baseados em troca catiônica. As amostras foram diretamente analisadas por CL-EMAR-Orbitrap. Foram estimados, como parâmetros de validação, seletividade, limite de detecção, repetitividade, recuperação, arraste e efeito de matriz. A repetitividade obtida foi de 96,19% e a recuperação foi de 83,80%. Arraste e efeito de matriz não foram observados. O presente método foi aplicado com sucesso na análise de amostras comerciais, nas quais foram verificadas adulterações, em sete das 11 marcas avaliadas, em diuréticos (conivaptan e politiazida) e estimulante (benfluorex). |
