Using the pork LDH ELISA system that our experiment was developed determined LDH content of ground beef. Ground pork that was cured and ground beef were placed in thermal death time tubes respectively and heated to 64, 66, 68, 70, 72, 74 or 74 degree C. SDS-PAGE and Western blotting of pocine muscle extracts indicated a decrease in the intensity of the PSA bands as temperature was increased. Polyclonal antibodies (PAb) against PSA were produced and a sandwich ELISA devised using biotinylated PAb as the detecting antibody. The PSA content decreased (p < 0.05) in ground cured pork heated between 68 and 76℃. The PSA content of three brand of pork hatdogs were 15.60 ± 4.24, 165.00 ± 42.43 and 3.45 ± 0.64 ng/g, respectively. The PSA content of three brand of pork sandwich hams were 18.30 ± 0.42, 165.00 ± 63.64 and 8.30 ± 3.25 ng/g, respectively. SDS-PAGE and Western blotting of bovine muscle extracts indicated a decrease in the intensity of the LDH bands as temperature was increased.
