Citric Acid

Introduction

Citric acid (CA) is an important weak organic acid. It is a colorless, odorless crystalline solid, readily soluble in water, and its aqueous solution is acidic. In biochemistry, it serves as an intermediate in the citric acid cycle (tricarboxylic acid cycle), which occurs in the metabolism of all aerobic organisms.

Citric Acid Used in the Food Industry

● Acidulant & flavor regulator: Imparts refreshing sourness to beverages, candies, and jams, balancing sweetness.

● Preservation: Extends shelf life of canned goods and juices by lowering pH to inhibit bacterial and mold growth.

● Processing aids: Reacts with sodium bicarbonate to produce effervescence (used in effervescent tablets and sodas); promotes pectin setting (for jelly production).

Citric Acid Used in the Household Use

● Descaling: Acidic dissolution of calcium carbonate deposits; used for removing scale from kettles, coffee machines, showerheads, and pipelines.

● Cleaning and rust removal: Acts as a mild pickling agent to remove rust and metal oxides, with low corrosiveness and no risk of chloride-induced stress corrosion; suitable for boilers and industrial piping.

● Eco-friendly: Readily biodegradable and safer than strong acids; serves as a key ingredient in green cleaning products.

Citric Acid Used in the Pharmaceutical Industry

● Pharmaceutical excipient: pH adjustment, buffering, and flavor correction to enhance drug stability and palatability.

● Anticoagulation application: Chelates calcium ions for use in blood collection to prevent clotting.

● Metabolism and safety: Participates in the tricarboxylic acid cycle for energy production; moderate intake helps alleviate fatigue.

Citric Acid Used in the Cosmetic Industry

● Exfoliation: As an AHA (alpha-hydroxy acid) ingredient, gently promotes skin cell turnover; used in whitening, anti-aging, and anti-acne products.

● pH regulation: Used in shampoos and facial cleansers to balance pH levels, close hair cuticles, and maintain hair shine.

● Synergistic enhancement: Formulated with vitamin C to chelate metal ions, thereby enhancing antioxidant effects.

Citric Acid Used in the Water Treatment Industry

Citric acid acts as a chelating agent to remove heavy metal ions from water, and is used for electroplating bath stabilization and as an absorbent for flue gas desulfurization.
