The objective of these studies was to identify a chemical indicator for predicting performance of enhanced pork during storage, then select raw materials with the potential for color and shelf life instability and enhance them with antimicrobial solutions in an attempt to overcome their initial deficits. The purpose of Study 1 was to evaluate the use of pH, glycolytic potential, and glucose levels in the drip to assess shelf life characteristics of modified atmosphere packaged (MAP), enhanced pork loin chops during display. Chops from higher pH carcasses had higher color scores and aerobic plate counts, and less discoloration.

Glycolytic potential was measured and the bimodal distribution was utilized to predict RN genotype. Diets containing 4.

Twenty-nine crossbred pigs, 16 normal (NN) and 13 halothane carrier (Nn) genotypes, were supplemented with 0 or 25 g x pig(-1) x d(-1) of CMH for 5 d before slaughter. Supplemented pigs gained 2.

L*, a*, and b* values, hue angle, chroma and visual color were determined. Color was evaluated using HunterLab (illuminants A, C, D(65) and F) and Minolta (illuminants C and D(65)) Spectrocolorimeters.
