Notizen:
Experiments detected effects of pH on lipid oxidation of fresh ground pork. Pigs received antemortem epinephrine injections or postmortem carcass electrical stimulation to manipulate ultimate postmortem pH. High-pH (〉6.10) samples had lower TBA values than low-pH samples. Nonsignificant difference in TBA values between high-pH prerigor- and postrigor-ground samples indicated that, at common high pH, time of grinding had no effect on lipid oxidation. Differences in TBA values between prerigor high- and low-pH samples and postrigor high- and low-pH samples indicated that, with identical grinding treatments, inhibition of oxidation occurred at high pH. Metmyoglobin was relatively high in both low- and high-pH muscle and was not catalytically active at high pH.
