Abstract

um teste de eficácia de conservante para determinar a eficácia de pelo menos um material conservante que está presente em um produto de consumo para reduzir ou eliminar os micro-organismos vivos que inclui desafiar o material conservante com pelo menos um micro-organismo derivado de uma cultura pura por inoculação de uma amostra do produto com uma quantidade de pelo menos um micro-organismo de desafio e permitir que os micro-organismos cresçam durante um intervalo predeterminado depois do qual o conservante é neutralizado e uma porção da amostra resultante é cultivada em um sistema de teste que inclui pelo menos um recipiente de teste, em que o recipiente de teste contém meio de crescimento líquido e meio de detecção capaz de monitorar o crescimento do micro-organismo através da detecção da subprodutos metabólicos gerados por crescimento de micro-organismos presentes no meio de crescimento líquido e produzir um sinal de saída que pode ser medido e analisado.
