Guar gum and $\kappa$-carrageenan were investigated as a substitutes for phosphate in pork meat processing. Emulsion-type pork sausages were prepared in which 0.5% phosphate was used for the control, and either $\kappa$-carrageenan or guar gum were added at levels of 0.1 or 0.5% for comparison. The hydrocolloid compounds significantly enhanced water holding capacity and cooking loss. However, hardness, cohesiveness, and chewiness were not well-maintained when compared to the control; this was attributable to the altered water distribution as well as enhanced water holding capacity of the sausages by the addition of $\kappa$-carrageenan and guar gum. Furthermore, the phosphate-free sausages had similar storage stability as the phosphate-added sausage. Overall, the results suggest that $\kappa$-carrageenan or guar gum can be used in place of phosphate in conventional processing to successfully prepare phosphate-tree pork sausages.

Guar gum, ${\kappa}$-carrageenan, alginic acid and chitosan were applied to pork as a model system, and evaluated as a substitute for inorganic polyphosphate, which is one of the essential additives in conventional meat processing. The tested materials did not alter the fat content or pH of the pork meat; however, they did affect water holding capacity and cooking loss significantly. The pork with added guar gum and ${\kappa}$-carrageenan exhibited lower cooking loss than the pork with added polyphosphate. Also, theses materials showed no negative coloring effect within the pork meat blends, which suggest the possibility for their application in final products. In addition, the pork processed with guar gum showed a similar emulsion stability to that with polyphosphate. Overall, guar gum and ${\kappa}$-carrageenan were confirmed as possible substitutes for inorganic polyphosphate.
