Product Portfolio: Tailored for Your Industry

Grade	Degree of Substitution (DS)	Viscosity (2% Solution, cps)	Key Applications
Food Grade	0.3–0.6	500–2000	Sauces, beverages, dairy products, frozen desserts
Industrial Grade	0.6–0.9	2000–5000	Oil drilling fluids, textile sizing, construction mortar
Pharmaceutical Grade	0.4–0.7	1000–3000	Tablet binders, disintegrants

Technical Advantages: Beyond Conventional Starches

Superior Performance

Thickening Efficiency: 0.5% dosage achieves viscosity equivalent to 2% native starch, reducing raw material costs by 30%.
Salt & pH Stability: Maintains viscosity in 1–18% NaCl solutions and pH 3–11, ideal for high-salt sauces and acidic beverages.
Thermal Resistance: Stable at 121°C (autoclaving) without viscosity loss, suitable for retorted foods.

Eco-Friendly & Safe

Biodegradable: 100% natural origin, compliant with EU REACH and US EPA standards.
Low Residue: Heavy metals <10 ppm, residual solvents <500 ppm, meeting FDA 21 CFR 172.892 requirements.

Process Optimization

Cold Water Solubility: Dissolves instantly without heating, reducing energy consumption by 25%.
Synergistic Effects: Enhances stability when blended with xanthan gum or CMC (e.g., in salad dressings).

Industry-Specific Solutions

Food & Beverage

Sauces & Condiments: CMS (DS 0.5) improves cling and shear-thinning properties, reducing syneresis by 40% in ketchup (Case Study: Italian Tomato Processor, 2024).
Dairy Products: Stabilizes yogurt texture with 0.3% addition, extending shelf life from 21 to 30 days.

Oil Drilling

Water-Based Mud: CMS (DS 0.8) reduces fluid loss by 53% in 20% brine drilling fluids, improving wellbore stability (API 13B-1 compliant).

Textile & Construction

Warp Sizing: Enhances yarn strength by 20% and reduces breakage during weaving.
Dry Mortar: Improves water retention by 35%, preventing cracking in cement-based materials.
