Circular sausage development starts with designing the matrix

A study published in *Foods* addresses an increasingly important question for cooked-sausage production: how can plant and poultry by-products be incorporated without losing control of texture, process technology or sensory acceptance? The work examines a cooked turkey sausage formulation containing apple pomace powder, turkey skin and iced water. This is not simply a matter of replacing ingredients; it is about tuning a meat matrix whose responses may interact.

The authors used response-surface methodology to relate the proportions of the three components to physicochemical, textural and sensory parameters. The approach matters because skin contributes fat and structural components; apple pomace adds fibre and fruit-derived compounds; and water directly affects protein extraction, emulsification and consistency. Any change in dosage can influence yield, bite, juiciness, colour and overall perception at the same time.

The study finds that the combined incorporation is technically feasible and identifies an optimised formulation balancing by-product use with the measured responses. That does not make apple pomace a universal ingredient for every sausage category. Its suitability will depend on the product, particle size, raw material, heating system and intended sensory profile.
