Red Beetroot Pigment – Natural Food Colorant

Red Beetroot Pigment – 100% Natural Water-Soluble Food Colorant

Basic Information

• Source: Roots of red beet (Beta vulgaris L. var. rubra)

• Appearance: Red to purple powder

• Main Component: Betanin

• Solubility: Easily soluble in water; insoluble in propylene glycol, acetone, and fatty solvents

• Stability: Good light stability; poor heat stability in acidic conditions

Overview
This natural red pigment is obtained from red beetroot through a process of extraction, filtration, purification, vacuum concentration, and drying. The main coloring component is betanin, a water-soluble pigment belonging to the betalain class. It provides a vibrant red to purple hue and is widely used as a clean‑label alternative to synthetic red dyes.

Color Characteristics
The shade of beetroot pigment is pH‑dependent:

• At pH 3–7: Red to purple

• At pH > 10: Yellow

This pH sensitivity should be considered when formulating products, especially in neutral or alkaline systems.

Applications

• Suitable for all types of food, particularly chilled and refrigerated products.

• Used in dairy products, confectionery, ice cream, beverages, sauces, and processed meats.

• Also applicable in cosmetics and dietary supplements where natural coloring is desired.

Recommended Usage
Dosage depends on the desired color intensity and product matrix. Typical usage ranges from 0.1% to 2.0% by weight of the product. Optimize through trial runs.

Processing
The pigment is produced through a multi‑step process:
Raw material → Extraction → Filtration → Purification → Vacuum concentration → Drying → Powder

Storage and Shelf Life

• Storage conditions: Store in a cool (5–10°C), dry place, away from heat, air, and direct sunlight.

• Shelf life: 12 months when stored under recommended conditions in unopened packaging.

• Once opened, use promptly and keep container tightly sealed to prevent moisture absorption and degradation.

Handling

• Use appropriate personal protective equipment (gloves, dust mask) when handling.

• Avoid exposure to heat and humidity during processing to maintain color stability.
