Functional Category: thickening agent
Distarch glycerol (DSG) is a carbohydrate-based food excipient with interesting functionalities in the food industry. Here's a breakdown of its properties and applications:
What is Distarch Glycerol?
- DSG is a modified starch product made by reacting starch with glycerol. This creates a versatile ingredient with properties that can be tailored depending on the ratio of starch to glycerol used.
Functions in Food:
DSG can offer several benefits depending on the specific type and the amount used:
- Thickener and Gelling Agent: At higher concentrations, DSG can act as a thickener or gelling agent, providing structure and texture to various food products.
- Film Former: It can form edible films around food items, potentially improving moisture retention or shelf life.
- Water Binder: DSG can help bind water in food, preventing dryness and improving texture.
- Freeze-thaw Stable: Some types of DSG are resistant to breakdown during freezing and thawing cycles, making them suitable for frozen foods.
Applications in Food:
Due to its versatility, DSG finds applications in various food products:
- Bakery fillings and glazes: for thickening and texture
- Confectionery: gummy candies, jellies
- Frozen foods: sauces, soups (for freeze-thaw stability)
- Meat products: binds water, improves texture
- Dietary products: can be a lower-calorie alternative to some thickeners or fat-based ingredients
Safety:
- Generally recognized as safe (GRAS) by the FDA for use in food at appropriate levels.
Important Considerations:
- The specific functionality and properties of DSG depend on the ratio of starch to glycerol used in its production.
- It's important for food scientists to choose the right type of DSG for the desired application.
Conclusion:
Distarch glycerol is a valuable food excipient offering thickening, gelling, water binding, and film-forming properties. It finds applications in various food products and can sometimes serve as a lower-calorie alternative to other ingredients. However, the specific functionality depends on the type of DSG used.
