High-fibre foods: a feasibility study using guar gum

Area of Science:

• Food Science
• Nutritional Science
• Rheology

Background:

• Therapeutic foods require specific viscosity for efficacy.
• Guar gum is a common food additive with thickening properties.

Purpose of the Study:

• To establish principles for producing high-viscosity therapeutic foods using guar gum.
• To determine the impact of guar gum concentration on food acceptability and viscosity.

Main Methods:

• Guar gum was incorporated into six food groups at varying concentrations.
• Food acceptability and final water content were assessed.

Main Results:

• Higher concentrations of guar gum could be incorporated into foods with lower final water content without significantly impacting acceptability.
• The study identified optimal ranges for guar gum incorporation based on water content.

Conclusions:

• Guar gum is a viable ingredient for creating high-viscosity therapeutic foods.
• Recipe modifications, particularly concerning water content, are crucial for successful domestic preparation and optimal guar gum functionality.
