1. Introduction

Lactic acid is one of the most important organic acids used in food, pharmaceutical, cosmetic, and industrial applications. Its salts—commonly known as lactates—are widely used as buffering agents, mineral supplements, preservatives, and functional ingredients.

Chemically, lactic acid is a hydroxycarboxylic acid with the formula:

C₃H₆O₃
Structure: CH₃–CHOH–COOH
IUPAC name: 2-hydroxypropanoic acid

It exists in two optical isomers:

• L-(+)-lactic acid

• D-(–)-lactic acid

The L-form is biologically active and commonly produced by fermentation.

2. Production of Lactic Acid

A. Fermentation Process (Most Common)

Raw materials:

• Glucose

• Sucrose

• Corn starch

• Molasses

Microorganisms used:

• Lactobacillus species

• Bacillus species

Basic steps:

1. Fermentation of carbohydrate substrate

2. Neutralization (usually with CaCO₃ or NaOH)

3. Filtration

4. Acidification

5. Purification (carbon treatment, ion exchange)

6. Concentration

This method yields high-purity food and pharma grade lactic acid.

B. Chemical Synthesis (Less Common)

Via acetaldehyde and hydrogen cyanide (historical method), but fermentation dominates due to sustainability and optical purity.

---

3. Physical and Chemical Properties

Lactic acid is hygroscopic and forms oligomers at high concentration.

---

4. Lactic Acid Salts (Lactates)

Lactic acid reacts with metals and bases to form lactate salts, which improve stability and usability in different formulations.

---

6. Advantages of Lactate Salts

• High bioavailability

• Better gastrointestinal tolerance

• Mild taste

• Stable and safe

• GRAS status (many lactates)

---

7. Market Trends

Global demand is increasing due to:

• Growth of biodegradable plastics

• Rising nutraceutical market

• Clean-label food preservatives

• Expansion of plant-based foods

Asia-Pacific dominates production due to fermentation infrastructure and corn availability.
