Food grade CMC plays a key role in the production of a variety of beverages due to its thickening, stabilizing, suspending, acid-resistant, and salt-resistant properties. Different beverages have different functional requirements, and the addition ratio also varies depending on the type and specific process.
1. Application of food grade CMC in plant protein beverages
Typical plant protein beverage categories: coconut milk, almond milk, walnut milk, peanut milk, soy milk, etc.
Specific functions:
After food grade CMC is dissolved in water, it can stabilize the protein particles in beverages : it wraps plant proteins (such as almond protein and peanut protein) through electrostatic adsorption to prevent them from aggregating and precipitating due to charge changes or gravity, thereby avoiding stratification.
Adjust taste: Food grade CMC with medium to high viscosity gives beverages a mellow and smooth taste, masks the roughness of plant ingredients, and avoids excessive "wateriness".
Heat stability: In high temperature treatments such as UHT sterilization, food grade CMC can reduce protein denaturation and aggregation and maintain system uniformity.
Addition ratio: The addition ratio of food grade CMC to plant protein beverages is usually 0.1%~0.5%. For example, 0.2%~0.3% is added to coconut milk, and 0.3%~0.5% may be needed to enhance suspension in walnut milk due to its coarse particles.
2. Application of food grade CMC in fruit pulp/juice beverages
Typical fruit pulp juice beverage categories: orange juice with pulp, orange juice with grains, mango juice, kiwi juice, etc.
Specific functions:
Suspended pulp particles: Food grade CMC forms a three-dimensional network structure by dissolving in water to "support" pulp particles (such as orange pulp and mango pieces), preventing sedimentation and ensuring a uniform appearance with "every particle visible".
Prevent water separation: Utilize the water retention of food-grade CMC to reduce water separation caused by pulp particle shrinkage and maintain stable viscosity.
Acid resistance: Food grade CMC is not easily degraded in a fruit acid environment with a pH of 3 to 5 and functions stably.
Addition ratio: The addition ratio of food grade CMC to fruit juice beverages is generally 0.15%-0.4%. Beverages containing large fruit pulp particles (such as Li Li Orange) require 0.3%-0.4%, while clarified fruit juices (such as clarified orange juice) can be as low as 0.15%-0.2%.
3. Application of food grade CMC in milk beverages and milk-containing beverages
Typical dairy beverages : lactic acid bacteria beverages, blended milk beverages, cocoa milk, coffee milk, etc.
Specific functions:
Stabilize milk fat and protein: Food grade CMC is adsorbed on the surface of fat droplets and casein, which can reduce the interfacial tension of proteins and prevent aggregation. At the same time, it increases the viscosity of beverages to delay the floating of milk fat and the precipitation of casein .
Synergistic emulsification: Food grade CMC can be combined with emulsifiers such as monoglycerides and sucrose esters to enhance the oil-water emulsification effect and reduce the sedimentation of particles such as cocoa powder and coffee powder.
Improve taste: Low to medium viscosity food-grade CMC can increase the smoothness of beverages , avoid the roughness of casein particles, and do not affect the freshness.
Addition ratio: The addition ratio of food grade CMC in milk beverages is usually 0.1%~0.3%. For example, lactic acid bacteria beverages have a high acidity and require 0.15%~0.25% addition; cocoa milk contains oil and solid particles and requires 0.2%~0.3%.
4. Application of food grade CMC in carbonated beverages
Typical categories: fruit-flavored carbonated drinks (such as lemon-flavored soda), carbonated drinks containing a small amount of fruit juice, etc.
Specific functions:
Stabilize flavor substances: Food grade CMC can absorb volatile flavors, reduce the volatility of carbonated beverages during storage, and maintain the stability of the aroma .
Anti-turbidity and precipitation: Food grade CMC can prevent the aggregation of tiny particles in juice or plant extracts, ensuring the clarity and transparency of the product.
Buffering bubble impact: Low-viscosity food grade CMC can reduce the impact of carbon dioxide bubbles on the system, avoid "gushing", and does not affect the refreshing taste.
Addition ratio: The addition ratio of food-grade CMC in carbonated beverages is usually 0.05%~0.15%. To maintain a refreshing taste, the dosage is lower, for example, 0.08%~0.12% is added to lemon-flavored carbonated beverages.
5. Application of food-grade CMC infunctional beverages
Typical categories: sports drinks, electrolyte drinks, drinks containing dietary fiber, etc.
Specific functions:
Electrolyte resistance and stability: Food grade CMC is not affected by electrolytes such as sodium and potassium, and can stably maintain the viscosity of functional beverage systems and avoid stratification of beverage products .
Suspending functional ingredients: Food grade CMC can help evenly disperse dietary fiber (such as inulin), herbal extracts, etc., and prevent particle sedimentation in such functional beverages .
Adjust taste: Food-grade CMC can moderately thicken the beverage to enhance its smoothness, lower the "thirst quenching threshold", and does not affect the absorption of minerals and vitamins.
Addition ratio: The addition ratio of food grade CMC to functional beverages is generally 0.05%-0.2%. Sports drinks require low viscosity and can be added at 0.05%-0.1%. Beverages containing dietary fiber can be increased to 0.1%-0.2% to enhance suspension.
6. Application of food grade CMC in other beverages
Eight Treasure Porridge canned beverages:
Function: High viscosity food grade CMC enhances the consistency of porridge beverage system, prevents beans and grains from settling, and reduces water precipitation at low temperature.
Adding ratio: The adding ratio of food grade CMC in porridge beverages is 0.3%~0.6% (due to the need for higher consistency).
Milk tea beverages:
Function: Food-grade CMC can stabilize the combination of milk protein and tea tannin, avoid "tea-milk stratification", and enhance the body.
The addition ratio of food grade CMC in milk tea beverages is generally 0.15%~0.3% (such as 0.2%~0.25% in milk tea).
Summarize
The core functions of food grade CMC in beverages are "stabilizing the system and optimizing taste." The addition ratio should be adjusted based on the beverage type (particle size, pH, and desired taste), ranging from 0.05% to 0.6%. In actual production, the optimal ratio must be determined through experimentation, taking into account raw material characteristics, process conditions (such as sterilization temperature), and synergistic effects with other additives (such as xanthan gum and pectin) to achieve a balance between stabilization and taste.
