I. Production Process Comparison
II. Product Performance and Application Comparison
III. Respective Limitations
- Plant-Extracted Betanin: Low raw material content leads to high costs; impurities compromise stability; heat sensitivity restricts applications; agricultural volatility creates supply and price risks.
- Fermented Betanin: Current production costs still need scale effects to further decrease; independent additive standards are lacking in some regions, requiring novel food approvals; consumer education (fermented vs. plant source) may be needed in certain markets.
IV. Selection Recommendations
- Existing low-temperature products (yogurt/ice cream/jelly) seeking organic certification or lower cost → Traditional plant-extracted betanin is sufficient.
- Need for enhanced heat stability, batch consistency, clean-label sustainability claims, or exporting to the U.S. market → Prioritize evaluation of fermented betanin (confirm local regulatory approval).
- High-temperature UHT / prolonged baking: Regardless of type, betanin has inherent limitations; consider blending with Monascus Red (water-based) or Paprika Oleoresin (oil-based).
