Easy oxidation. Sun exposure can promote the degradation and fading.

Soluble in water and aqueous, insoluble in nonpolar solvent. 

food color pigment- radish red pigment aqueous medium pH value with increased,

 the maximum absorption peaks back happened, spectrophotometry is decreased obviously.

Tonal with medium pH value solution by 2.0 to 8.0 and in turn show: orange red-pink-red-violet. 

food color pigment- radish red pigment to hot water solution is not stable,

 increases with temperature, degradation accelerated, and fade away, but in acidic condition is stable.

Cu2 + can speed up its degradation, and make a blue; Fe3 + can make this product solution into rust yellow; Mg2 Ca2 + +, this product has a little influence on; Al3 +, Sn2 + to it has protection. 

Source and Make: 

 with redcore radish as raw materials, the cleaning, shred, squeezing have red juice. Slag by acid aqueous or aqueous extraction), have to filtrate. Merger to squeeze out the juice and extraction filtrate, refined, dry.
