How Sodium Lactate Enhances Food Preservation and Skin Hydration

Introduction

Sodium lactate, the sodium salt of lactic acid, is a multifunctional ingredient widely used in the food, pharmaceutical, and cosmetic industries. Derived from natural fermentation processes, it is known for its safety, versatility, and effectiveness. This compound serves as a preservative, humectant, and pH regulator, making it an essential additive for modern applications.

Key Properties of Sodium Lactate

• Chemical Nature: A clear, odorless liquid with mild saline taste.

• Moisture Retention: Strong humectant, prevents drying in foods and cosmetics.

• pH Regulation: Helps stabilize formulations by buffering acidity.

• Antimicrobial Action: Inhibits growth of harmful microorganisms.

• Biodegradable & Safe: Derived from natural fermentation, widely recognized as safe (GRAS).

Applications in Food Industry

1. Meat Products – Extends shelf life by reducing microbial growth and enhancing water retention.

2. Bakery & Confectionery – Maintains freshness, prevents staling, and balances flavor.

3. Beverages – Used as a pH regulator to stabilize drinks.

4. Dairy Products – Improves texture and prevents spoilage.
