Beetroot Red Color Extract - Betanin from China Suppliers and Factory for Natural Food Coloring
Beetroot red color, which is also called beet red color, is obtained by extracting it from the beetroot. The process of producing powder form color involves leaching, separation, concentration, and drying to obtain a refined product. The main component is betanin, the product is the purple-red liquid or powder, easily soluble in water, and slightly in ethanol solution.
Stability & Properties
A natural color with bright color, good dyeing force, light fastness poor thermal resistance, and moisture activity influence. To maintain the purple color and hue stability, it is important to maintain PH levels between 4.0 to 6.0 in aqueous conditions. Light, oxygen, metal ions, etc. can promote its degradation. Moisture activity greatly affected the stability of beet color, and its stability increased with the decrease in moisture activity. Ascorbic acid has a certain protective effect on betalain.
Health & Bioactivity
The betalain colors display potent antioxidant, anti-inflammatory, and chemo-preventive activity in vitro and in vivo. Betanin has anti-inflammatory and hepatic protective functions in human cells. This compound can modulate redox-mediated signal transduction pathways involved in inflammation responses in cultured endothelial cells and has also displayed antiproliferative effects on human tumor cell lines. In both healthy and tumoral human hepatic cell lines, it controls the mRNA and protein levels of detoxifying/antioxidant enzymes, exerting hepatoprotective and anticarcinogenic effects.
Because it is all-natural and beneficial to the body, it is commonly used as a colorant in various foods, health products, cosmetics, drugs, etc.
Frequently Asked Questions
Q1: How is beetroot red color obtained?
Beetroot red color is extracted directly from the beetroot. The production process involves leaching, separation, concentration, and drying to obtain a high-quality refined product in liquid or powder form.
Q2: What is the main component and solubility of beetroot red color?
The main active component is betanin. This natural color is easily soluble in water and slightly soluble in ethanol solutions, presenting as a vibrant purple-red liquid or powder.
Q3: How do pH levels affect the stability of beetroot red color?
To maintain optimal purple color and hue stability, it is crucial to keep the pH levels between 4.0 and 6.0 in aqueous environments.
Q4: What factors can cause beetroot red color to degrade?
The stability of beetroot red color is influenced by light, oxygen, metal ions, and moisture activity. Decreasing moisture activity increases its stability, and ascorbic acid can be used to provide a protective effect.
Q5: What are the health benefits associated with betalain colors?
Betalain colors display potent antioxidant, anti-inflammatory, hepatoprotective, and chemo-preventive activities. They help modulate key cellular pathways and display antiproliferative effects on tumor cell lines.
Q6: In which industries is beetroot red color commonly applied?
Due to its natural origin and health benefits, beetroot red color is widely used as a natural colorant in foods, health products, cosmetics, and pharmaceutical drugs.
