The objective was to determine structural and physicochemical properties of beef emulsion modeling systems prepared with native breadfruit flour and four different extruded breadfruit flours. Extrusion conditions for the flours were summarized as two different specific mechanical energies (74 or 145 kJ/kg) and four unique melt temperatures (83 °C, 100 °C, 105 °C, or 126 °C). Meat emulsions formulated at 3% replacement of beef with native or extruded breadfruit flours were compared with control (no additional flour) formulations. Replacement of beef with breadfruit flour (either native or extruded) did not significantly change cooking loss or instrumental redness values of cooked meat emulsions. Interestingly, replacement of beef with the fully gelatinized extruded breadfruit flours altered viscosity during heating as indicated by lower values for storage modulus (44.75% to 62.53% decrease compared with control) and lower values for loss modulus (25.90% to 52.54% decrease compared with control). This resulted in meat emulsions with a significant reduction in textural hardness (28.78% to 37.62% decrease compared with control).
