Estudio comparativo de los métodos de Tillmans y de Roe, para la valoración del ácido ascórbico

Abstract

A comparative study of the Tillmans and Roe's methods for evaluation of ascorbic acid is made. It has been found that the titration with 2-4- dimitrophenylhydrazine gives good results when used in fresh vegetables containing ascorbic and dehydro-ascorbic acids.
