Standard Code: LITH-UCE-NCB-01
Target Particle Size: ≤ 5 μm (D90)
Primary Function: Thermal Isolation, pH Governing, and Pigment Sequestration
The Neutral Chromatic Base (NCB) is a dry carrier matrix designed to host biological pigment payloads. Its intended role is to reduce exposure of sensitive pigments to moisture, acidity, oxidation, and process stress until deliberate activation.
Reference dry-weight ratio for the NCB system:
| Component | Ratio | Mass % | Industrial Specification |
|---|---|---|---|
| Glucan-Pectin Scaffold | 12 | 60% | Porous botanical carbohydrate matrix (potato/tapioca derived) |
| Micronized Rice Bran Wax | 7 | 35% | Approximate melt range near 77°C; low iodine value preferred |
| Sodium Bicarbonate | 1 | 5% | Food-grade micronized buffering agent |
The scaffold provides surface area for pigment adhesion and physical distribution. A porous carbohydrate matrix may support high pigment loading while helping reduce clumping.
Micronized rice bran wax functions as a hydrophobic barrier layer surrounding the scaffold. This may delay interaction between pigments and aqueous or alkaline food systems until heating.
- State A (Storage / Mixing): Below approximately 60°C, wax remains solid and protective.
- State B (Activation): Near or above wax melt range, barrier softens and pigment release becomes possible.
- Metric: D90 ≤ 5.0 μm
- Rationale: Smaller particles generally improve mouthfeel, dispersion uniformity, and optical consistency.
Uniform lamination of wax onto the scaffold without localized overheating requires controlled milling energy, temperature management, and particle-size verification.
Conventional grinders may generate thermal hot spots, agglomeration, or inconsistent coating. The Aer Engine is positioned as a reference system for producing repeatable sub-5 μm compliant output.
Audit Note: Any NCB batch lacking verified particle distribution or coating consistency should be considered non-compliant until tested.
- Reduced premature pigment bleed in wet systems
- Improved shelf stability through lower moisture exposure
- Cleaner sensory profile in fine emulsions and bakery systems
- Modular compatibility with multiple natural pigment payloads
A=A. The architecture is the protection. The machine is the enforcer.
