DEFINITION AND BASIC REQUIREMENTS First Edition EXTRACTO DESCRIPTORES: Tecnología de los alimentos, te, definiciones, requerimientos básicos. ICS: 67.140.10 ICS: 67.140.10 Prólogo ISO (la Organización Internacional de Normalización) es una federación mundial de organismos nacionales de normalización (organismos miembros de ISO). El trabajo de preparación de las Normas Internacionales normalmente se realiza a través de los comités técnicos de ISO. Cada organismo miembro interesado en una materia para la cual se haya establecido un comité técnico, tiene el derecho de estar representado en dicho comité. Las organizaciones internacionales, gubernamentales y no gubernamentales, en coordinación con ISO, también participan en el trabajo. ISO colabora estrechamente con la Comisión Electrotécnica Internacional (IEC) en todas las materias de normalización electrotécnica. Las normas internacionales se redactan de acuerdo con las reglas establecidas en la Parte 2 de las Directivas ISO/IEC. La tarea principal de los comités técnicos es preparar Normas Internacionales. Los proyectos de Normas Internacionales adoptados por los comités técnicos se envían a los organismos miembros para votación. La publicación como Norma Internacional requiere la aprobación por al menos el 75% de los organismos miembros que emiten voto. Se llama la atención sobre la posibilidad de que algunos de los elementos de este documento puedan estar sujetos a derechos de patente. ISO no asume la responsabilidad por la identificación de cualquiera o todos los derechos de patente.

El té negro puede ser producido a partir de té de un cultivo o región o puede ser una mezcla de tés de dos o más orígenes. Las características deseadas de un té negro y del licor resultante, dependerá de muchos factores, incluyendo el tipo de agua que se utiliza para elaborar la bebida, el método de preparación y los gustos individuales. Los objetivos de esta Norma Internacional son especificar la planta de la que el té verde es fabricado y establecer los requisitos para características químicas determinadas que, de cumplirse, son una indicación de que el té ha sido sometido a las buenas prácticas de manufactura. Se trata de que de las partes interesadas tengan la posibilidad de aplicar los requisitos de esta Norma Internacional a un envío o lote de té negro. La calidad del té suele ser evaluado organolépticamente por catadores calificados de té, que basan sus juicios en su experiencia previa sobre el té, su conocimiento de las condiciones de las zonas productoras y las preferencias del país consumidor. Podrá tener en cuenta características tales como la apariencia del té antes de la preparación de un licor (tales como forma, color, limpieza y uniformidad), la apariencia de la hoja en infusión y el aspecto, olor y sabor del licor. En la práctica, el té se presenta para su análisis químico sólo si un catador de té sospecha que el producto ha sido adulterado, o si presenta características anormales.

    Tea - Wikipedia, the free encyclopedia 03-11-09 12:04 Tea From Wikipedia, the free encyclopedia Tea is the agricultural product of the leaves, leaf buds, and internodes of the Camellia sinensis plant, prepared and cured by various methods. "Tea" also refers to the aromatic beverage prepared from the cured leaves by combination with hot or boiling water,[1] and is the common name for the Camellia sinensis plant itself. After water, tea is the most widely-consumed beverage in the world.[2] It has a cooling, slightly bitter, astringent flavour which many enjoy.[3] The four types of tea most commonly found on the market are black tea, oolong tea, green tea and white tea,[4] all of which can be made from the same bushes, processed differently, and in the case of fine white tea grown differently. Pu-erh tea, a post-fermented tea, is also often classified as amongst the most popular types of tea.[5] Green Tea leaves in a Chinese The term "herbal tea" usually refers to an infusion or tisane of gaiwan. leaves, flowers, fruit, herbs or other plant material that contains no Camellia sinensis.[6] The term "red tea" either refers to an infusion made from the South African rooibos plant, also containing no Camellia sinensis, or, in Chinese, Korean, Japanese and other East Asian languages, refers to black tea.

Received: 16 August 2013; in revised form: 31 October 2013 / Accepted: 18 November 2013 / Published: 29 November 2013 Abstract: Green teas in leaf form are brewed multiple times, a common selling point. However, the flavor changes, both sensory and volatile compounds, of green teas that have been brewed multiple times are unknown. The objectives of this study were to determine how the aroma and flavor of green teas change as they are brewed multiple times, to determine if a relationship exists between green tea flavors and green tea volatile compounds, and to suggest the number of times that green tea leaves can be brewed. The first and second brews of the green tea samples provided similar flavor intensities. The third and fourth brews provided milder flavors and lower bitterness and astringency when measured using descriptive sensory analysis. In the brewed liquor of green tea mostly linalool, nonanal, geraniol, jasmone, and β-ionone volatile compounds were present at low levels (using gas chromatography-mass spectrometry).
