FAQS SOBRE NATAMICINA
DICIEMBRE 2020
¿Qué factores ambientales perjudican los efectos conservantes de la natamicina?
• pH: Su rango óptimo de actuación es entre 5 y 7. Cuando el pH del medio es más ácido,
su acción de conservación disminuye hasta un 10%. Es peor cuánto más extremo por
básico (sobre 9) o ácido (bajo 4) es el pH, y se calcula que su eficacia disminuye hasta
un 30%.
• Calor: La natamicina es estable a temperatura ambiente, y tampoco se altera si se
sobrepasan los 100ºC mientras sea por un tiempo breve. Esto es importante para su
aplicación en la industria de productos lácteos, puesto que el producto sobre el cual se
aplique se podrá pasteurizar, pero sí que sufrirá una pérdida de actividad la
natamicina. También se ve afectada por las temperaturas superiores a los 50ºC si se
mantienen durante más de 24h.
• Luz: La exposición continuada de la natamicina a la radiación UV provoca su
degradación, así que es muy perjudicial para su acción conservante.
Como la natamicina no actúa directamente contra bacterias, virus o protozoos, puede verse
degradada por estos organismos si están presentes a lo largo del tiempo. También los
productos químicos que contienen cloro o peróxidos son perjudiciales para su efectividad.
