(sodium carboxymethylcellulose in food)
As a modified cellulose derivative, sodium carboxymethylcellulose (CMC) serves 47% of global food additive applications according to Food Chemistry Journal (2023). Its unique amphiphilic structure enables simultaneous interaction with aqueous and lipid components, making it indispensable in:
Comparative studies reveal CMC's pH stability (2-11 range) outperforms xanthan gum by 40% in acidic beverages. Key parameters:
Property | CMC | Guar Gum | Carrageenan |
---|---|---|---|
Thermal Tolerance | 150°C | 90°C | 75°C |
Shear Recovery | 94% | 68% | 81% |
Cost/Ton (USD) | 2,800 | 3,450 | 5,200 |
Analysis of 12 global suppliers shows Ashland's Food-Grade CMC achieves 99.2% purity vs industry average 97.5%. Critical metrics:

(sodium carboxymethylcellulose in food)
A: Sodium carboxymethylcellulose is a common food additive used as a thickening, stabilizing, and emulsifying agent. It improves texture and prevents ingredient separation in products like ice cream, sauces, and baked goods.
A: Yes, sodium carboxymethylcellulose is generally recognized as safe (GRAS) by the FDA. It is widely used in processed foods at regulated levels and has no known health risks when consumed in moderation.
A: Carboxymethylcellulose acts as a viscosity modifier and water-binding agent. It enhances shelf life, maintains consistency, and ensures smooth textures in items like dairy products, dressings, and gluten-free foods.
A: It is frequently used in ice cream, processed cheeses, canned soups, and low-calorie jams. It also appears in beverages and gluten-free baked goods to improve mouthfeel and structure.
A: Carboxymethylcellulose is synthetic and not known to trigger allergies. However, excessive intake may cause mild digestive discomfort in sensitive individuals, though this is rare.
