  • Title: Study of the effect of canola proteins-xanthan based Pickering emulsion as animal fat replacer in a food matrix produced from mechanically separated meat.

    Abstract:
    Pickering emulsions stabilized by protein microgel, and hydrocolloid have shown desirable properties to be used as animal fat replacers. However, the potential applications of these structures as animal fat replacers in meat systems formulations have not been explored yet. Therefore, novel Pickering emulsions stabilized by canola proteins microgels and xanthan gum were developed, and their potential as animal fat replacer in meat systems was assessed for the first time. In the present study, 25, 50, 75, and 100% animal fat content were replaced by Pickering emulsion. Moreover, the obtained results revealed that complete fat replacement with canola proteins-based Pickering emulsion in meat emulsion improved its nutritional value by significantly enhancing the percentage of protein, monounsaturated and polyunsaturated fatty acid composition, and reduction of saturated fatty acid content compared to control (100% animal fat). Reformulation with PEs enhanced the meat systems' technological behavior such as emulsion stability and cooking loss, and oxidative stability. Also, significant total color difference (ΔE *) was observed only in samples with 100% fat replacement. Meat systems containing fat replacement ≤50% showed the closest texture parameters to the control sample. This study provides a promising alternative to replace animal fat with plant-based ingredients in meat systems.
