Resumo: | The objective was to develop an isotopic analysis method to quantify carbon from the C3 photosynthesis cycle in apple-flavoured soft drinks. The beverage was produced in the laboratory according to Brazilian law. Adulterated soft drinks were also produced containing quantities of clarified juice below the legal limit. The isotopic analyses measured the relative isotopic enrichment of the apple soft drinks and their purified sugar fractions. From these results the quantity of source C3 was estimated by means of the isotopic dilution equation. To determine the existence of adulteration in commercial soft drinks, it was necessary to create a legal limit according to Brazilian law. Three commercial brands of soft drinks were analyzed and one was classified as adulterated. The method developed was proved to be efficient to measure the quantity of carbon from a C3 source in commercial appleflavoured soft drink. The legal limit was an important methodological innovation which enabled the identification of beverages in conformity with Brazilian law. By following the steps of the present work, this methodology can be applied to other clarified fruit beverages as a means to verify their legality. |

Esta bebida foi produzida em laboratório, conforme a legislação brasileira. Também foram produzidos refrigerantes adulterados com quantidade de suco clarificado de maçã abaixo do permitido. Nas análises isotópicas, foi mensurado o enriquecimento isotópico relativo dos refrigerantes e de sua fração açúcar purificado. Com estes resultados, foi estimada a quantidade de fonte C3 por meio da equação da diluição isotópica. Para determinar a existência de adulteração nos refrigerantes comerciais, foi necessária a criação do limite de legalidade de acordo com a legislação brasileira. Três marcas de refrigerante comerciais foram analisadas. Uma foi classificada como adulterada. O método desenvolvido provou ser eficiente para mensurar a quantidade de carbono de origem C3 em refrigerantes de maçã comerciais. O limite de legalidade foi uma importante inovação metodológica que permitiu identificar as bebidas que estão em conformidade com a legislação brasileira. Seguindo as etapas deste trabalho, esta metodologia pode ser aplicada para outras bebidas clarificadas de frutas como um meio para verificar sua legalidade.Universidade Estadual Paulista, Departamento de Física e Biofísica, Instituto de Biociências de BotucatuUniversidade Estadual Paulista, Departamento de Horticultura, Faculdade de Ciências Agronômicas de BotucatuFAPESP: 06/60898-7Universidade Estadual Paulista (Unesp)Figueira, Ricardo [UNESP]Ducatti, Carlos [UNESP]Venturini Filho, Waldemar Gastoni [UNESP]2016-04-01T18:44:42Z2016-04-01T18:44:42Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article69-74application/pdfhttp://dx.doi.org/10.4260/BJFT2010130100009Brazilian Journal of Food Technology, v. 13, n. 1, p. 69-74, 2010.1981-6723http://hdl.handle.net/11449/13721010.4260/BJFT2010130100009ISSN1981-6723-2010-13-01-69-74.pdf1030251743943217Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengBrazilian Journal of Food Technology0,206info:eu-repo/semantics/openAccess2024-04-30T14:34:10Zoai:repositorio.unesp.br:11449/137210Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T22:25:31.745845Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
