# Dextrin Syrup: Properties and Applications in Food Industry
## Introduction to Dextrin Syrup
Dextrin syrup is a versatile carbohydrate product derived from the partial hydrolysis of starch. This process breaks down starch molecules into smaller chains of glucose units, resulting in a syrup with unique functional properties. As a food ingredient, dextrin syrup plays a significant role in various food applications due to its specific characteristics.
## Chemical and Physical Properties
Dextrin syrup possesses several distinctive properties that make it valuable in food processing:
– Solubility: Highly soluble in water, forming clear solutions
– Viscosity: Lower viscosity compared to unmodified starch
– Sweetness: Mild sweetness, typically less than sucrose
– Hygroscopicity: Moderate water-binding capacity
– Thermal stability: Resistant to heat degradation
– Fermentability: Can be fermented by microorganisms
## Production Process
The manufacturing of dextrin syrup involves several key steps:
1. Starch selection (commonly from corn, wheat, or potato)
2. Acid or enzymatic hydrolysis
3. Controlled heating process
4. Purification and filtration
5. Concentration to desired solids content
## Applications in Food Industry
### Confectionery Products
Dextrin syrup serves as an important ingredient in candy manufacturing:
– Provides body and texture to hard candies
