Fabrication and characterization of non-fat whipped cream analogue: Effects of type and concentration of polysaccharide.

In the present study, the non-fat whipped cream analogue was formulated by the combination of soy protein isolate, different polysaccharides and sucrose. Compared with single polysaccharide, the combined polysaccharide showed synergistic effect on formulating the non-fat whipped cream with better properties. The non-fat whipped creams showed high overrun (up to 570 %), excellent drainage stability (no drainage occurred within 120 min) and comparable hardness (up to 1.1 N) than that of control (a commercially dairy whipped cream). Moreover, the non-fat whipped creams were all solid-like (storage modulus > loss modulus) and exhibited outstanding shape retention ability. These properties were greatly affected by the types and ratios of combined polysaccharide. The combination of anionic and neutral polysaccharides was more beneficial for its properties, and the effect depended on the combined ratios. Especially for samples containing gellan gum/guar gum, their appearance only changed slightly after standing for 60 min, and simultaneously showed satisfying sensory acceptability when the combined ratio was 2/3. Therefore, these novel non-fat whipped creams could be popularized as the functional products aiming at specific groups such as diabetes and obesity people in the future.
