Product Overview
Citric acid is a weak organic acid naturally found in citrus fruits. It is the most widely used food acidulant, providing fresh, clean sour taste to adjust acidity in food systems. It also has metal sequestration property, binding metal ions to reduce oxidation and discoloration. It is available in two commercial forms: citric acid monohydrate and citric acid anhydrous, sharing the same core functions but differing in crystal water content to suit various formulation needs. It is widely applied in beverages, food processing and pharmaceutical applications.
Core Characteristics
1.Fresh, bright and clean sour taste, widely recognised food acidulant
2. metal sequestration property to minimise metal-induced oxidation and colour shift
3.Freely soluble in water, easy to dissolve and distribute
4.Two forms available: citric acid monohydrate and citric acid anhydrous, for different formulation requirements
Main Functions
1.Acidulant Citric acid provides a sharp, fresh and immediate sour taste. It adjusts acidity and balances sweetness in a wide range of food and beverage products. It is the most commonly used acidulant in the food and beverage industry.
2.Metal Sequestration Citric acid binds metal ions such as iron and copper. This secondary effect helps reduce oxidative discoloration and protects flavour stability in finished food products.
3.Flavor Enhancement & Preservative Aid It enhances fruit flavour and lowers pH to support microbial control, extending shelf life in acidic food systems.
Applications
1.Beverages The largest application field, widely used in carbonated drinks, fruit juices, sports drinks and flavoured water. It provides bright tartness and adjusts acidity in various beverages.
2.Food Processing Applied in jams, jellies, canned fruits, confectionery and dairy products for acidity adjustment and colour stability.
3.Pharmaceuticals & Dietary Supplements Used as acidulant and excipient in effervescent tablets, syrups and nutritional formulations.
4.Other Fields Also used in eco-friendly cleaning formulations for descaling.
Packaging&Storage
Packaging: 25kg food-grade plastic woven bag or kraft paper bag, inner food-grade PE lining.
Storage: Stored in dry and cool environment, away from moisture and high temperature.
