Kappa Refined Carrageenan Food Grade - Excellent Gelling and Thickening Agent
Kappa Carrageenan is a natural sulfated polysaccharide extracted from select species of red seaweed (Rhodophyta), engineered to deliver precise gelling, thickening, and stabilizing functionalities in food and industrial applications. This purified hydrocolloid combines marine-sourced sustainability with consistent performance, offering formulators a clean-label solution for texture modification across hot and cold processing systems.
Core Functional Properties
1. Superior Gelation Dynamics
- Forms rigid, heat-reversible gels at concentrations as low as 0.5% (w/w) in aqueous systems
- Achieves gel strengths of 800–1,200 g/cm² (1.5% solution, 20°C, Bloom method)
- Melting point: 50–60°C; setting point: 35–45°C (adjustable via cation optimization)
2. Synergistic Interactions
- Konjac synergy: Enhances elasticity by 40% in combined gels (1:1 ratio)
- Locust bean gum: Increases gel clarity and freeze-thaw stability (3-cycle retention >85%)
- Xanthan gum: Boosts shear-thinning behavior for pourable dressings
3. Thermal & pH Resilience
- Maintains viscosity within ±5% across 20–90°C thermal cycling
- Stable in pH 3–9 range (FDA 21 CFR 172.620 compliant)
- Withstands UHT processing (140°C/4s) with <8% viscosity loss
4. Sensory & Physical Profile
- Appearance: Off-white to tan free-flowing powder (80–120 mesh)
- Odorless with neutral taste impact (ISO 5492 sensory certified)
- Brookfield viscosity: 1,500–2,200 cP (1.5% solution, spindle LV-4, 60 rpm)
Technical Specifications
- CAS No.: 9000-07-1
- Sulfate Content: 25–30% (IC analysis)
- Ash Content: ≤15% (ISO 928)
- Moisture: ≤12% (ISO 1666)
- Particle Size: 95% <150 μm (ISO 13320 laser diffraction)
- Microbial Standards: Total plate count <5,000 CFU/g; E. coli absent/25g
Application Excellence
Dairy Alternatives
- Stabilizes plant-based cheeses (45% fat mimetic performance)
- Prevents whey separation in vegan yogurts during shelf life
- Enhances mouthfeel in almond milk lattes (HST ≤15 Pa·s⁻¹)
Meat & Seafood
- Improves water-binding in injected poultry (6–8% yield increase)
- Creates self-supporting gels for surimi products (NMR T₂ relaxation <120 ms)
- Reduces purge in cooked hams (<2% over 60-day storage)
Confectionery
- Enables sugar-free gummy production (texture similarity ΔE <1.5 vs. sucrose)
- Accelerates setting time in aerated marshmallows by 30%
- Maintains shape fidelity in chocolate fillings during enrobing
Pharmaceuticals
- Forms sustained-release matrix tablets (USP dissolution Type II compliance)
- Stabilizes emulsions in topical creams (D[4,3] droplet size <5 μm)
- Acts as vegan capsule alternative to gelatin (disintegration time <30 mins)
Industrial Solutions
- Bio-based adhesive thickener in paper coatings (TAPPI T648 conformance)
- Encapsulation matrix for controlled-release agrochemicals
- Rheology modifier in non-toxic children's paint (ASTM D4236 certified)
Regulatory & Sustainability
- FDA GRAS, EU Commission Regulation (EC) No 231/2012
- ISO 17088 compostability certified
- MSC Chain of Custody for wild-harvested seaweed
- Carbon footprint: 1.2 kg CO₂eq/kg (cradle-to-gate analysis)
Operational Advantages
- Cold-water dispersible with high-shear mixing (3,000–5,000 rpm)
- Compatible with high-calcium systems (up to 150 ppm Ca²⁺)
- 36-month shelf life in moisture-controlled packaging (<0.3% RH ingress)
Formulation Guidance
Standard Gel Preparation
- Hydrate 0.8–1.2% carrageenan in 60°C deionized water
- Add 0.1–0.3% KCl or CaCl₂ to optimize gel strength
- Heat to 75°C for full dissolution, cool to 40°C for setting
Synergistic Systems
- Dairy desserts: 0.4% κ-carrageenan + 0.2% locust bean gum
- Plant-based meat: 0.6% κ-carrageenan + 0.8% konjac flour
- Fruit preparations: 0.3% κ-carrageenan + 0.15% xanthan gum
Kappa Refined Carrageenan empowers formulators to achieve clean-label texture innovation while maintaining processing efficiency. Its unique ability to create customizable gels—from brittle to elastic—makes it indispensable for modern food systems requiring plant-based, allergen-free, or reduced-additive solutions. Backed by rigorous quality controls and marine stewardship commitments, this hydrocolloid delivers reproducible performance across ambient, chilled, and thermally processed products.
