Notes:
Proteins (280 nm absorbance) in water extracts from bovine semi-membranosus and porcine longissimiu were separated by size exclusion (SEC) high performance liquid chromatography(HPLC). SEC/HPLC profiles showed six heat sensitive fractions ≥ 10,000 daltons. These fractions ranged from peak 1 at 375,800 daltons in bovine and 170,000 daltons in porcine down to myoglobin, peak 6, at 15,200 and 19,500 daltons for bovine and porcine, respectively. SEC/HPLC showed the loss of certain peaks at specific time/temperature treatments. Heat labile porcine proteins ≥ 10,000 daltons represented about 41.5 area percent of the total extractable components after heating to 60°C. In bovine, this represented about 37.5 area percent. In both species, heating at 70°C for 30 min or at 75°C for 0 min resulted in protein solubility loss to about 1 area percent or less.
