Surimi-like protein ingredient from porcine spleen as lean meat replacer in emulsion-type sausages.

The aim of this work was to assess the influence of a porcine spleen surimi-like protein ingredient as pork meat replacer in emulsified cooked meat products (frankfurter-type sausages). The effects of the addition of porcine spleen protein isolate (SPI) in substitution of lean meat at concentrations of 5%, 10% and 15% on the physicochemical characteristics, microstructure, textural, and sensorial properties of the sausages were investigated. The addition of SPI did not affect the emulsion stability of raw meat batters nor the proximate composition of the cooked sausages, provided that sausages are formulated considering the differences in protein and fat content between pork meat and spleen protein fraction.
