PROCEDIMIENTO:
Primero se procedió a medir por separado 20 ml de leche en 2
recipientes A y B.
Utralizar
Luego al recipiente (A) se le agregó 2 gotas de fenolftaleína y
neutralizar con NAOH 0,1N 4.5 (gasto) hasta obtener una coloración
ligeramente rosada.
Posteriormente al recipiente (b) sele agregó 2 gotas de fenolftaleína y
neutralizar con NAOH 0,1N 3.6 (gasto) hasta obtener una coloración
ligeramente rosada.
ANÁLISIS BROMATOLÓGICO DE
LECHE
Concluyendo dichos procedimientos se hizo los siguientes cálculos en
base a los mL de NAOH 0,1N gastados:
1ml NAOH 0,1N ---------------------- 0.009grs Ac.làctico
4.5 ml NAOH 0,1N-------------------- X
X=0.0405 grs
0.0405grs.......................en (20ml)
Y .......................en(100ml)
Y = 0.20 %
El valor de acidez de la leche “A” es de 0.20 % superando en un
considerable porcentaje al valor máximo estándar (18%).
1ml NAOH 0,1N ---------------------- 0.009g Ac.làctico
3.6 ml NAOH 0,1N -------------------- X
X= 0.0324 g
0.0324 g ........................ en (20ml)
Y ………………… en (100ml)
Y = 0.16 %
El valor de acidez de la leche “B” es de 0.16 % por lo tanto esta
dentro del valor normal de acidez permitido.
Rosita nos faltó fotos (2).si puedes lo pones o si no
que se va hacer(las fotos son de la leche de color
