Thiocyanate content in raw milk under the american tropic conditions in relation to the activation of the lactoperoxidase system
نویسنده
چکیده
The potential risks in the use of thiocyanate salt for the activation of the Lactoperoxidase System (LPs) have been strongly discussed at international level. This study approaches different factors associated to variations of the thiocyanate ion concentrations in milk under the tropic conditions. Mean thiocyanate concentrations in bulk milk are between 0,10-0,15 mmol/liter, with a general mean of 0,140 mmols/L, which indicates that the exogenous activation of the LPs can be done with a lesser salt quantity and that the maximal natural concentration is 2,4 times higher than that established by the guidelines about its use. A criterion regarding of overdose, for the control of use of the LPs is established. Under these conditions, activation is safe and does not involve toxicological risks for consumers. Keys word: milk, thiocyanate content, Lactoperoxidase System. Contenido de tiocianato en leche cruda en las condiciones del tropico americano y su relación con la activación del sistema lactoperoxidasa RESUMEN: Los riesgos potenciales en el uso de una sal de tiocianato para activar el sistema lactoperoxidasa (LP), es un tema de discusión a nivel internacional. El estudio aborda los diferentes factores asociados a la variación de las concentraciones del ion tiocianato en la leche en condiciones del trópico. La concentración media de tiocianato en mezclas se encuentran entre 0,10-0,15 mmoles/litro, con una media general de 0,140 mmoles/L, lo que indica que la activación exógena del sistema LP se puede realizar con una cantidad menor de la sal y que la máxima concentración natural es 2,4 veces superior al establecido por las directrices de uso. Se establece un criterio de sobredosificación para el control de uso del sistema LP. Bajo estas condiciones la activación es segura y no entraña riesgo toxicológico para los consumidores. Palabras clave: leche, tiocianato, Sistema Lactoperoxidase.

Activity of raw milk lactoperoxidase-thiocyanate-hydrogen peroxide (LP) system on four Listeria monocytogenes strains at refrigeration temperatures after addition of 0.25 mM sodium thiocyanate and 0.25 mM hydrogen peroxide was studied. The LP system exhibited a bactericidal activity against L. monocytogenes at 4 and 8 degrees C; the activity was dependent on temperature, length of incubation, a...

Efficiency of N2 Gas Flushing Compared to the Lactoperoxidase System at Controlling Bacterial Growth in Bovine Raw Milk Stored at Mild Temperatures
To prevent excessive bacterial growth in raw milk, the FAO recommends two options: either cold storage or activation of the lactoperoxidase system (LPs/HT) in milk with the addition of two chemical preservatives, hydrogen peroxide (H) and thiocyanate (T). N2 gas flushing of raw milk has shown great potential to control bacterial growth in a temperature range of 6-12°C without promoting undesire...

Human milk and saliva from newborn infants were analyzed for their content of lactoperoxidase and thiocyanate. The activity of lactoperoxidase in infant saliva was variable but generally higher than that found in calf saliva. In contrast, the activity in human colostrum was low ( approximately 5%) compared with that found in cow's milk. The enzyme was resistant to gastric juice. Thiocyanate was...
