Etude des conditions optimales pour la détermination des composés phénoliques totaux par le réactif de Folin-Ciocalteu

open access: yesOENO One, 1972
En milieu alcalin, les phénols réduisent le mélange d'acide phosphotungstique et phosphomolybdique en oxydes bleus de tungstène et de molybdène. Cette propriété est utilisée pour le dosage des composés phénoliques du vin en faisant appel au réactif de ...
