Introduction: 

Sorbitol (CAS: 50-70-4, 98201-93-5), also known as D-Glucitol or L-Gulitol, is a natural sugar alcohol (polyol) widely used across industries for its sweetening and moisture-retaining properties. Commonly found in food, pharmaceuticals, and cosmetics, Sorbitol's low glycemic impact makes it a valuable ingredient for health-conscious and diabetic-friendly products.

Chemical Profile:

     Molecular Formula: C6H14O6
     Molar Mass: 182.17 g/mol
     Density: 1.28 g/mL at 25°C
     Melting Point: 98-100°C
     Boiling Point: 105°C at 760 mmHg
     Flash Point: >100°C
     Water Solubility: Highly soluble (235g/100g water at 25°C)
     Solubility: Also soluble in glycerin and propylene glycol; slightly soluble in methanol, ethanol, and other organic solvents.
     Appearance: White crystalline powder

Storage Conditions:

To preserve its stability and purity, Sorbitol should be stored in a sealed container at room temperature, away from moisture.

Applications:

1  Vitamin C Production:
         Intermediate Role: Sorbitol serves as a key intermediate in the synthesis of vitamin C (ascorbic acid).

2  Nutritional Sweeteners:
         Low-Calorie Alternative: Used as a sweetener in food products due to its sugar-like taste and minimal effect on blood sugar levels, making it suitable for diabetic-friendly formulations.

3  Humectants:
         Moisture Retention: Sorbitol is utilized in foods, pharmaceuticals, and cosmetics to maintain moisture content, ensuring product longevity and texture stability.

4  Chelating Agents:
         Metal Ion Binding: Applied in processes where removal of metal ions is needed, enhancing the quality and consistency of products.

5  Stabilizers:
        Product Stability: Sorbitol prevents crystallization and other physical changes, maintaining the desired consistency in various formulations.

6  Special Sweetener:
        For Diabetics:As Sorbitol doesn't require insulin regulation or convert to glucose, it is often used in products aimed at those managing diabetes.

7  Food Industry:
       Cakes and Confectionery: In baked goods, Sorbitol can be used at levels up to 5.0g/kg. It is also incorporated into surimi products at 0.5g/kg and enhances textures in chewing gum and candy.

8  Defoaming Agent:
       Processing Aid: Sorbitol helps control foam in sugar production, brewing, and the processing of bean products.

9  Moisturizing Agent:
       Preservation: It aids in preserving the texture and moisture of currants, alcoholic beverages, and cooling drinks, contributing to product shelf life.

Conclusion:

Sorbitol is a multifunctional polyol that offers significant benefits as a sweetener, humectant, and stabilizer. Its low impact on blood sugar levels and ability to retain moisture makes it an ideal ingredient for health-conscious and diabetic-friendly food products, as well as a critical component in the pharmaceutical and cosmetic industries. Storing Sorbitol properly ensures its efficiency and quality in these diverse applications.
