Development of an orange-flavoured functional beverage formulated with beta-glucan and coenzyme Q10-impregnated beta-glucan

Abstract

An orange-flavoured functional beverage formulated with oat beta-glucan (BG) powder or coenzyme Q10-impregnated beta-glucan (iBG), and sweetened with stevia extract was developed to demonstrate the potential use of BG or iBG as a functional ingredient in beverage formulations. The BG and iBG (CoQ10 loading 3.3%) were obtained using the pressurized gas-expanded (PGX) liquid technology. The addition of citric acid had no effect on the viscosity of iBG or BG beverages. The beverage quality was evaluated by a consumer sensory panel. Based on a triangle test, there was no overall difference between the beverages prepared with BG and iBG. Ideal profile method was applied to evaluate the overall consumer acceptance of the beverages prepared with 0.2% iBG. Principal component analysis was performed to evaluate the product space among 0% iBG beverage, 0.2% iBG beverage, Vitaminwater® and ideal product. The effect of providing health information was tested, and the positive effect of health information on overall acceptance was demonstrated.
