Abstract
Introduction. The aim of the work was to study the effect of oat β-glucan on the viscosity-speed indicators of mixtures and physicochemical characteristics of milk-vegetable ice cream. Materials and methods. Milk-vegetable ice cream with a mass fraction of fat 3% and oat β-glucan in the amount of 0.5– 1.0% with a stabilization system and without, as well as control samples of classic milk ice cream, were prepared. Rotational viscometry and well-known methods for studying the resistance to melting, overrun and ice cream dispersion of the air phase were used. Results and discussion. The structuring ability of β-glucan in ice cream with low fat and dry matter content was studied. The effective viscosity of ice cream mixtures with β-glucan in the amount of 0.5–1.0% is in the range of recommended values. Mixtures of milk ice cream with β-glucan are characterized by thixotropic ability, which is confirmed by the high degree of restoration of the destroyed structure. Combined use of β-glucan and fermented vegetable puree containing soluble pectin and softened vegetable fibers could significantly improve the viscosity-speed indicators of mixtures: the effective viscosity increases by 11.5–15.9%, the degree of recovery in on average – by 10%. Low-fat milk-vegetable ice cream with a β-glucan content of 0–1.0% acquires a creamy consistency. The increase in overrun and resistance to melting of ice cream with β-glucan is due
