Product Overview

Calcium Citrate is a citrate salt derived from citric acid. As a standard food additive E333, it is a multi-functional ingredient widely adopted in global food and nutrition industries.

Different from common acidic regulators, Calcium Citrate is weakly alkaline and neutralizing. It not only adjusts and stabilizes food pH value, but also serves as an excellent calcium source for nutritional fortification. It has stable chemical properties, high safety, and will not affect the original flavor of finished food.

It is commonly used for pH buffering, calcium supplementation, anti-caking, texture firming and flavor stabilization.

Key Product Characteristics

1.Mild pH buffering property, neutralizes excess acidity in food systems

2.Excellent calcium fortification effect with high bioavailability

3.Stable structure, not easy to deteriorate during processing and storage

4.Good anti-caking performance for powder food formulations

5.Firming and stabilizing effect for dairy and solid food

6.Odorless, tasteless, compatible with all kinds of food raw materials

7.Fully compliant with international food safety standards

Core Product Functions

1. Calcium Nutritional Fortifier: Calcium Citrate is one of the most popular food-grade calcium sources. It helps supplement dietary calcium, improve nutritional value of food and beverages, and is widely used in health food and dairy products.

2. pH Buffer & Acidity Stabilizer: It neutralizes excessive acid in food systems, stabilizes pH value, balances taste, and prevents sourness overload in beverages and processed foods.

3. Anti-Caking Agent: Effectively prevent powder agglomeration in solid drinks, seasoning powder and nutritional powder, maintain loose and uniform texture.

4. Firming Agent: Improve food texture stability, keep fruit and vegetable products crisp and firm, prevent softening and deformation during processing.

5. Flavor Stabilizer: Protect food flavor, reduce taste deterioration, and extend product shelf stability.

Application Scope

1. Beverage & Solid Drinks: Used in functional drinks, protein drinks and solid beverage powder for calcium fortification and anti-caking treatment.

2.Dairy & Fermented Products: Applied in milk, yogurt and dairy desserts to stabilize pH and enhance nutritional calcium content.

3.Bakery & Powder Food: Used in flour products, baking powder and seasoning powder as anti-caking agent and pH stabilizer.

4.Canned Fruits & Vegetables: Act as firming agent to maintain crisp texture of canned food.

5.Health Food & Nutrition Formulations: Widely used in nutritional supplements, tablets and functional food as high-quality calcium source.

Packaging & Storage

Packaging: Standard food grade packaging

Storage Condition: Store in cool, dry and ventilated environment. Keep sealed to avoid moisture absorption and agglomeration.
