The investigation of production of ice cream containing Donalila salina alga powder

The aim of this study was to investigate the effect of Dunaliella salina addition in concentrations of 0.1, 0.25, 0.5, 0.75, 1 and 1.5% as substitutes for 6.7, 16.7, 33.4, 50, 66.7 and 100% stabilizers on the rheological, physicochemical and sensory properties of the ice cream samples. All samples showed a shear-thinning behavior. Dunaliella salina addition increased significantly the apparent viscosity and decreased melting rate (P<0.05). Also, the addition of Dunaliella salina increased significantly in the overrun and decreased the hardness of the samples (P<0.05). The sensory evaluation suggests that the addition of Dunaliella salina does not have a significant effect on odor and flavor. Samples containing the highest percentage of Dunaliella salina were received the highest color, appearance and hardness scores by panelists. In general, samples containing a high percentage of Dunaliella salina were selected as the best overall acceptance by panelists. As a general result, according to the results of this study, the addition of Dunaliella salina to ice-cream, while improving the qualitative characteristics of the product, also improves its sensory properties and improves the acceptance of the product.
