Black Carrot Extract
Black carrot extract powder is a highly concentrated natural pigment and bioactive compound derived from the root of the black carrot, scientifically known as Daucus carota ssp. sativus var. atrorubens. The extraction typically involves aqueous or hydroalcoholic maceration, followed by filtration, concentration, and spray-drying. It is prized for its intense, stable coloration and potent antioxidant properties.
Applications of Black Carrot Extract
Black carrot extract powder is a versatile ingredient across several sectors:
- Food and Beverage Industry: Widely used as a highly stable natural food colorant (E163). It provides a deep red, burgundy, or purple hue depending on the pH of the application. Ideal for beverages, confectionery, fruit preparations, and dairy.
- Nutraceuticals: Incorporated into dietary supplements and protein powder mixes for its potent antioxidant and anti-inflammatory properties, largely attributed to its high concentration of acylated anthocyanins.
- Cosmetics: Used in natural skincare and makeup formulations as a stable, antioxidant-rich pigment for lip products and color cosmetics.
Chemical Constituents of Red Beetroot Extract
- Anthocyanins: The dominant pigment molecules, specifically acylated and non-acylated derivatives of cyanidin (e.g., cyanidin-3-xylosyl-glucosyl-galactoside). Acylation provides superior stability compared to other anthocyanin sources.
- Phenolic Acids: High concentrations of chlorogenic acid, caffeic acid, and ferulic acid, which contribute significantly to antioxidant capacity.
- Carotenoids: Minor amounts of beta-carotene and lutein, depending on the specific cultivar.
- Carbohydrates: Naturally occurring root sugars and complex polysaccharides.
Identification Numbers
Key regulatory and chemical identifiers for black carrot extract include:
- CAS Number: 84929-61-3 (Daucus carota extract general)
- EC Number: 284-545-1 (Daucus carota extract general)
- E-Number (Food Additive ID): E163 (Anthocyanins – broad category)
- INCI Name: Daucus Carota Sativa (Carrot) Root Extract
Safety, Handling, and Storage Conditions
- Safety Profile: GRAS (Generally Recognized As Safe). Non-toxic and non-hazardous. As with any fine powder, inhalation may cause mild respiratory irritation; standard dust masks and gloves are advised during industrial handling.
- Storage: Like most botanical extracts, it is hygroscopic and sensitive to environmental degradation. It must be packed in airtight, moisture-impermeable containers.
- Environmental Conditions: Store in a cool (< 25°C), dry place away from direct sunlight and strong odors. While black carrot anthocyanins are relatively stable to heat and light compared to other sources, prolonged exposure will still cause degradation and color loss.
Synonyms and Nomenclature
In the industry, black carrot extract is known by several alternative names:
- Purple carrot extract
- Daucus carota root extract
- Anthocyanin extract (Black Carrot)
- E163 (when classified broadly as an anthocyanin colorant)
