PATENT BLUE V - Uses and synthesis methods
Introduction
Patent Blue V, also known as Food Blue 5, Sulphan Blue, Acid Blue 3, L-Blau 3, C- Blau 20, Patentblau V, Sky Blue or C. I. 42051, is a dark blue synthetic triphenylmethane dye used as food coloring. As a food additive, its E value is E131. It is the sodium or calcium salt of the internal salt of [4-(α-(4-diethylaminophenyl) -5-hydroxy-2, 4-disulfophenyl methylene)-2, 5-cyclohexadiene-1-subunit] diethylammonium hydroxide.
application
Patent Blue V is a dark blue-purple powder particle that can be used as a food blue pigment.
identification test
Solubility soluble in water; hardly soluble in ethanol. Measured according to OT-42 method.
pigment identification test shall be determined by OT-16 method.
content analysis
the total pigment content was determined according to method 2 in the OT-15. The conditions are as follows: the sample mass is 1.3~1.4g; 15g of sodium hydrogen tartrate in buffer solution; The pigment mass per mL0.1mol/L TiCl3 is equivalent to 0.02898g of calcium salt or 0.02913g of sodium salt.
Toxicity
ADI is not specified (FAO/WHO,2001).
HACSG regulations shall not be used for children's food.
use limited
EEC(1990) can be used for Scotch omelet.
