Free chlorine does not interfere with this product up to 500 mg/L (as hypochlorite); interference may occur above this. No numeric threshold is specified for peracetic acid; interference is indicated by a color change in the alert zone, signaling unreliable results. Please see the link below to access a user guide.

General description
El peróxido es un desinfectante polivalente que, debido a su excelente acción antivírica, bactericida y fungicida, se utiliza ampliamente en la industria alimentaria. La peroxidasa transfiere el oxígeno del peróxido a un indicador rédox orgánico. Esto da lugar a un producto de oxidación amarillo-marrón. La concentración de peróxido se mide de manera semicuantitativa por comparación visual de la zona de reacción en la tira reactiva con los campos de la escala de color. Cada tira tiene también una segunda zona de reacción (zona de alerta). Esta zona cambia de color en presencia de elevadas concentraciones de peróxido (a partir de aproximadamente 2000 mg/l (H2O2) y de concentraciones interferentes de ácido peracético. Las tiras reactivas son perfectas para el preanálisis rápido y económico de una muestra para estimar la concentración de peróxido y un posible factor de dilución antes de utilizar un método cuantitativo como el ensayo de peróxidos Reflectoquant® o Spectroquant®.
Diseño para beneficios de sostenibilidad:
Seguimos demostrando nuestro compromiso con nuestro planeta y un futuro sostenible explorando formas de mejorar los productos existentes en nuestra cartera. Recientemente hemos revisado la línea actual de tiras reactivas MQuant® para identificar oportunidades clave destinadas a minimizar el impacto sin comprometer el rendimiento del producto.
Este producto se ha beneficiado de:
- Tira reactiva con reducción
- Tubo de aluminio reciclado
- Folleto de instrucciones digital
Application
- Control de calidad de los alimentos: en la industria alimentaria, las pruebas de peróxido se utilizan para determinar el valor de peróxido en aceites vegetales y otras grasas comestibles. Esta aplicación es crucial para evaluar la frescura y la vida útil de los productos alimenticios. En un estudio reciente se demostró el uso de dispositivos analíticos en papel para la determinación colorimétrica de los valores de peróxido en aceites vegetales, destacando la simplicidad y la eficacia de este método para las pruebas de calidad sistemáticas de los alimentos (Ghohestani et al., Food Chemistry, 2023).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
