Beetroot Red is usually a reddish-purple powder, water-soluble, slightly soluble in ethanol, and insoluble in organic solvents such as anhydrous ethanol. In aqueous solutions, it provides a vivid red to reddish-purple color. It maintains good stability in pH 3.0–7.0, with maximum stability between pH 4.0–5.0. While offering excellent dyeing properties, it has poor heat resistance—higher temperatures, light, and oxygen accelerate its degradation. High levels of Fe³⁺ and Cu²⁺ ions may cause browning.

Beetroot Red is a natural reddish-purple pigment recognized for its vibrant hue and water solubility. It creates bright red to reddish-purple solutions and is most stable in slightly acidic conditions, particularly at pH 4.0–5.0. While highly effective as a coloring agent, it requires careful handling since heat, light, oxygen, and high concentrations of metal ions can reduce stability or cause browning.
