UTILIZATION OF RESPONSE SURFACE MODELING TO EVALUATE THE EFFECTS OF NONMEAT ADJUNCTS AND COMBINATIONS OF PSE AND RFN PORK ON THE TEXTURE OF BONELESS CURED PORK

Abstract

ABSTRACTCombinations of pale, sop, and exudative (PSE) and red, firm. and nonexudative (RFN) semimembranosus muscle were utilized to manufacture chunked and formed, cured pork. Response Surface Methodology was utilized to investigate the effects of soy protein concentrate (SPC), sodium caseinate (SC), and modified food starch (MFS) on bind and texture profile analysis. Fifteen adjunct formulations for five PSE and RFN combinations provided 75 treatments for each of three replications. As CIE L* values of raw muscle increased, protein‐protein bind decreased (P<0.05). MFS, SC, and SPC decreased (P<0.05) cohesiveness. MFS and SC decreased (P<0.05) chewiness, and MFS decreased (P<0.05) hardness. Utilizing these adjuncts demonstrated that MFS improved texture in PSE and RFN pork. This research demonstrated that diluting RFN pork with no more than 25% PSE pork permits the formation of a high quality boneless deli ham roll.
