China Red Radish Color - Quality Radishes from Leading Suppliers and Factory
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 the pH is below 5, purple-red when the pH is 5-7, and blue when the pH is above 7. In acidic conditions, the color is stable to heat and light.
Brief Production Process
The pigment is obtained through:
- 1 Slicing red radish roots.
- 2 Extraction and filtration.
- 3 Purification and vacuum concentration.
- 4 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.
Application
Natural pigment, widely used in beverages, juice, confections, sorbets, sauces, candies, jams, cakes, and jellies etc. in the pH range of 2.5-4.5.
Frequently Asked Questions
What is Red Radish Color and how is it sourced?

What are the solubility characteristics of Red Radish Color?
The active pigment in Red Radish Color is anthocyanin. It is easily soluble in water and ethanol, but it is not soluble in oil.
How does the pH level affect the color of Red Radish pigment?
The color changes dynamically based on the pH value: it appears orange-red when the pH is below 5, purple-red when the pH is between 5 and 7, and turns blue when the pH is above 7.
What is the production process for manufacturing Red Radish Color?
The pigment is produced through a four-step process: first, slicing the red radish roots; second, extraction and filtration; third, purification and vacuum concentration; and finally, sterilization and drying to produce the powder form.
What are the common applications of Red Radish Color?
As a natural pigment, it is widely used in food and beverage products such as juices, confections, sorbets, sauces, candies, jams, cakes, and jellies, typically within a pH range of 2.5 to 4.5.
How stable is Red Radish Color under different environment conditions?
While it has poor stability to light, heat, and oxidizing agents generally, it is stable to heat and light under acidic conditions. Specifically, under pH 3.0-5.0 aqueous conditions, the red color remains more stable.
