Abstrakt: A novel approach for the recovery of the proteins contained in the effluent formed during production of surimi-like material from mechanically recovered poultry meat was proposed, using an integrated membrane process comprising microfiltration, ultrafiltration and vacuum membrane distillation. Additionally, the possibility of using the integrated membrane process to achieve high-quality water for reuse was also investigated. Using cross-flow membrane techniques, it was found that the total recovery of soluble proteins as well as the average degree of concentration amounted to 84 % and 9.3, respectively. Moreover, using this process, the total recovery of water was 70 % and the percentage reduction in COD, TOEM and TSS in the permeate obtained using vacuum membrane distillation exceeded 99 %. As a result, the water recovered by the integrated membrane process could be reused in the manufacture of surimi-like material from mechanically recovered poultry meat. [ABSTRACT FROM AUTHOR]
