The Effect of α-, β- and γ-Cyclodextrin on Wheat Dough and Bread Properties

Area of Science:

• Food Science
• Carbohydrate Chemistry
• Materials Science

Background:

• Cyclodextrins (CDs) are cyclic oligosaccharides with diverse applications.
• CDs possess health benefits, suggesting potential as food supplements and nutraceuticals.
• Understanding CD interactions with food matrices like wheat dough is crucial.

Purpose of the Study:

• To investigate the effects of alpha (α)-, beta (β)-, and gamma (γ)-CDs on wheat dough and bread properties.
• To determine optimal CD concentrations for minimal impact on bread quality.
• To explore CD interactions with gluten proteins.

Main Methods:

• Alveograph analysis for dough viscoelastic properties.
• Assessment of bread volume and staling.
• Texture analysis and low field nuclear magnetic resonance (LF-NMR) spectroscopy for staling.

Main Results:

• Beta-CD (β-CD) significantly affected dough viscoelasticity, indicating interaction with gluten proteins.
• Bread volume was generally unaffected up to 4% CD, with 4% α-CD slightly increasing it.
• Higher CD concentrations reduced bread volume; no effect on bread staling was observed.

Conclusions:

• Up to 4% CD can be incorporated into wheat bread with minor effects on dough and bread characteristics.
• CDs show potential for use in wheat-based food products without compromising quality.
• Further research into specific CD-protein interactions could optimize applications.
