Organismos modificados genéticamente
Soluciones innovadoras para la detección de GMO en los alimentos
Organismos modificados genéticamente
La producción mundial de alimentos modificados genéticamente (por ejemplo, soja y maíz) ha aumentado de forma continua desde el comienzo de la década de los 90.
Desde el 1 de septiembre de 1998, todos los productos alimentarios que contienen organismos modificados genéticamente (GMO) se deben especificar en la etiqueta. De acuerdo con la normativa del Consejo de Ministros de la Unión Europea (UE), normativa para etiquetado de nuevos alimentos: N.º de decisión 1139/98/CE. Además, la directiva de la UE 1829/2003, que entró en vigor en abril de 2004, determina un valor umbral de etiquetado del 0,9 % en la UE para alimentos y piensos.
Detección cualitativa de GMO
De acuerdo con la normativa nacional o regional, se aplican unos niveles de tolerancia cero a los eventos de GMO no aprobados. De ahí que, por el momento, solo se consideren de interés los análisis cualitativos en estos productos. El límite de detección se encuentra en el 0,01 %, dependiendo de la matriz y la aplicación.
La regulación CE 619/2011 es una normativa especial para piensos. Siempre que se cumplan ciertas condiciones (caducidad de la aprobación de la UE, aprobación en el país de origen, disponibilidad de ensayos y material de referencia, etc.), se aplicará un valor umbral técnico del 0,1 % para eventos de GMO no aprobados. Esto es particularmente importante en las importaciones de maíz y soja con y sin GMO, no siempre libres de contaminación.
Detección cuantitativa de GMO
En los eventos de GMO aprobados respectivamente, existe la pregunta cuantitativa de si el producto supera los valores umbral definidos o los valores de etiquetado obligatorios.
En Europa, se aplica un valor del 0,9 % al evento de GMO en la matriz vegetal respectiva. Por debajo de este valor, no es necesario declarar productos alimentarios con contaminaciones casuales o técnicamente inevitables de eventos de GMO (CE 2829/2003 y EC2830/CE). La cuantificación se consigue a través de la cuantificación respectiva de un gen específico de GMO y un gen específico de matriz vegetal de acuerdo con una curva de calibración diferente en ambos casos, y la conversión al número de copias de ADN de GMO/matriz vegetal. Al multiplicar esta unidad adimensional por 100 se obtiene como resultado el valor de porcentaje. La curva de calibración se obtiene mediante la dilución de un estándar de ADN y, de acuerdo con un material de GMO definido, también se puede especificar de forma precisa con un factor de corrección experimental.
Cribado de GMO
El cribado de secuencias de genes extrínsecas a la planta infiltradas en ella durante el desarrollo del GMO proporciona una evidencia eficiente de la presencia de posibles GMO.
Las secuencias genéticas utilizadas habitualmente son las siguientes:
This promoter, made from the cauliflower mosaic virus, is the most frequently used element. Plant samples that are only 35S positive can also be contaminated with the naturally occurring virus. False positive results can be ruled out by using the virus-specific CaMV (S2027) test.
The Nopalin Synthase Terminator (NOS) from Agrobacterium tumefaciens is often but not exclusively used in combination with 35S.
In lieu of 35S, the figwort mosaic virus promoter can also be used in GMOs.
The gene for phosphinotricin-N-acetyltransferase from Streptomyces hygroscopicus can enable a resistance against the herbicide glufosinate that is available under several different brand names.
This sequence denotes the transition from chloroplast transit peptide to 5-enolpyruvylshikimate-3-phosphate synthase from Arabidopsis thaliana and Agrobacterium spp. It enables a resistance against the herbicide glyphosate.
Estos y otros parámetros se pueden combinar de forma modular o bien utilizar por separado. La eficiencia de la preparación del ADN se puede verificar mediante el kit PLANT Plus (S2049) específico de la planta.
