Effects of Gamma Irradiation on the Chemical Properties of Actin and Actomyosin of Meatsa

Abstract: Effects of gamma irradiation on the chemical properties of actin and actomyosin during aging of meats have been studied. Meats were irradiated with 4 X 10" rad of cobalt-60 gamma rays at 40°F in three.steps, i.e., immediately after slaughter, at maximum rigor, and at "rigor off." Actin and two kinds of actomyosin (AMS and AML, previously reported by authors) were isolated from irradiated and control meats. The contents of sulfhydryl groups and amino acids, viscosity, the activity of ATPase and ATP sensitivity … Show more

“…Actomyosin is a bound form of actin and myosin that negatively affects protein solubility. Irradiation with gamma rays can depolymerize actomyosin molecules ( Fujimaki et al, 1961 ). By determining the peptides below 5 kDa generated after irradiation using liquid chromatography with tandem mass spectrometry analysis, it was revealed actin shows higher resistance than myosin to fragmentation by gamma ray irradiation ( Zhang et al, 2020 ).…”

“…Strahlendosen bis 5 Mrad bewirken die Bildung neuer Peptide; bei Dosen von 1,5-2 Mrad steigt der Gehalt an freien Aminosauren an [3]. Actin scheint, ini Vergleich zu Actomyosin, nur wenig empfindlich zu sein [16]. Einzelne EiwciDfraktionen, deren Loslichkeit dann meist sinkt, werden durch die Bestrahlung verschiedenartig beeinflu& [15].…”
