Gardenia Yellow / Blue / Green Powder (Natural Color System)
1. Can it withstand high temperature processing?
Will the color degrade during 85–105°C heating (e.g., gummy cooking, beverage pasteurization)?
Solution：
Use post-addition method (add after heating when possible)
Apply spray-dried encapsulated form for better protection
Keep heating time as short as possible
Avoid alkaline conditions during heating
Key idea: Process control is more important than raw material resistance
2. Is it stable in acidic systems (pH 2.5~4)
Will the color fade or shift in acidic beverages or gummies?
Solution：
Maintain system pH at 3.0~5.5 optimal range
Use buffer systems (e.g., citrate buffer)
Avoid excessive acid overload (too much citric acid)
For Blue & Green: use controlled formulation ratios
Key idea: pH control = color stability
3. Is it fully soluble and clear in solution?
Does it cause cloudiness, precipitation, or poor clarity in drinks?
Solution:
Pre-dissolve color in water before mixing
Add color under proper stirring sequence (water first, then color)
Use fine filtration (0.45~1 μm if needed)
Avoid direct mixing with high calcium or protein systems
Key idea: Mixing order determines clarity
4. Is Gardenia Blue / Green stable as a real pigment system?
Is Blue stable alone? Is Green a true pigment or just a mixture?
Solution:
Use controlled genipin-based reaction system
Standardize reaction conditions (time, temperature, amino ratio)
For Green: use designed co-stabilized system (not simple mixing)
Add stabilizers like maltodextrin or gum arabic if needed
Key idea: Green is a system design, not just blending colors
