Introduction
Red Radish Color is the pigment obtained by extracting roots of Red Radish (Raphanus sativus L.), a cruciferous plant. It is a dark red powder, and the active pigment is anthocyanin, which is easily soluble in water and ethanol, but not soluble in oil.
The color changes with the pH value: the color is orange-red when pH is below 5, purple-red when pH is 5-7, and blue when pH is above 7. In acidic conditions, the color remains stable to heat and light.
Brief Production Process
The pigment is obtained through:
01
Slicing red radish roots
02
Extraction and filtration
03
Purification and vacuum concentration
04
Sterilization and drying (for powder form)
Feature
💡
Pure natural, bright color, strong dyeing ability, poor stability to light, heat and oxidizing agent. Under pH 3.0-5.0 aqueous conditions, it is red and its color is more stable.
