About Gluconic Acid

Gluconic acid is a mild organic acid found naturally in honey, wine, and fruits. It is commonly used as a food preservative, chelating agent, and pH regulator in various industries. Gluconic acid is also known for its antioxidant properties and is sometimes used in cosmetic and pharmaceutical applications. It is produced commercially through the fermentation of glucose by certain bacteria or by the oxidation of glucose using enzymes. Gluconic acid and its salts have a wide range of applications due to their versatility and safety profile.

Properties of Gluconic Acid

Gluconic acid is a mild, noncorrosive, and nontoxic organic acid. It has a refreshing sour taste and has a chemical formula of C6H12O7 and a molecular weight of 196.155 g/mol. It has a melting point of 131°C and is soluble in water. Gluconic acid has a pKa of 3.86, indicating it is a weak acid. The gluconate anion can chelate various metal ions, making gluconic acid useful in cleaning products and as a concrete admixture.

Manufacturing Process of Gluconic Acid

The first step in manufacturing is substrate preparation, where various carbon sources such as glucose, molasses, grape must, or other sugar-rich substrates are pretreated through processes like hydrolysis, filtration, or pH adjustment to prepare them for the fermentation stage. Next, the fermentation process takes place, using microorganisms such as the fungus ‘Aspergillus Niger’ or the bacteria ‘Gluconobacter Oxydans’. These microbes are inoculated into the prepared substrate and undergo aerobic fermentation, converting the sugars into gluconic acid. After the fermentation, the gluconic acid is recovered from the broth through filtration or centrifugation, which is then purified, often by ion exchange or crystallisation. The purified gluconic acid is then neutralised with a base, such as sodium hydroxide or calcium carbonate, to form sodium gluconate or calcium gluconate. Finally, the gluconic acid or its salt is dried and packaged for commercial distribution.

Synthesis of Gluconic Acid

Raw Materials:

1. Glucose (C6H12O6)

2. Oxygen (O2)

3. Water (H2O)

Step 1: Enzymatic Oxidation of Glucose

Gluconic acid is produced by the oxidation of glucose using glucose oxidase enzyme.

Reaction: C6H12O6 + O2 + H2O → C6H12O7 + H2O2

In this reaction, glucose is oxidised to gluconic acid, and hydrogen peroxide is produced as a by-product.

Step 2: Catalytic Decomposition of Hydrogen Peroxide

The hydrogen peroxide produced in the first step can be decomposed catalytically to water and oxygen to prevent any inhibitory effects on the enzyme and to ensure the purity of the gluconic acid.

Reaction: 2H2O2 → 2H2O + O2

Step 3: Purification

The resulting gluconic acid solution is then purified. This may involve filtration, ion exchange, or other purification techniques to remove any impurities and by-products.

Step 4: Concentration and Drying

The purified gluconic acid solution is concentrated through evaporation. If a solid form is required, the solution is further dried to produce gluconic acid crystals or powder.

Applications and Drivers of Gluconic Acid

One of the major application areas for gluconic acid is the food and beverage industry, where gluconic acid and its derivatives like glucono delta-lactone (GDL) are used as a potent taste improver in tofu production, bakery goods, dairy products, and meat processing.

Other significant applications for gluconic acid is in the pharmaceutical, construction, and personal care industry. Increasing government spending on infrastructure development, particularly in the Asia-Pacific and North American region, is a key factor boosting demand for gluconic acid. In terms of regional trends, the Asia-Pacific region is the fastest growing market for gluconic acid. This is due to high exports and production, especially from countries like China and Japan.
