The effect of electron beam irradiation on IgG binding capacity and conformation of tropomyosin in shrimp.

To evaluate the effect of electron beam (EB) irradiation on IgG binding capacity and conformation of tropomyosin in shrimp (Solenocera melantho), shrimp meat was irradiated with different doses (0, 1, 3, 5, 7, 9 kGy) of EB. IgG binding capacity of TM from shrimp meat was detected by western blot and indirect enzyme-linked immunosorbent assay. The conformation of TM was analyzed with circular dichroism and Fourier transform infrared spectroscopy.

Effects of electron beam irradiation on the biochemical properties and structure of myofibrillar protein from Tegillarca granosa meat.

The effect of electron beam irradiation at doses of 0-9 kGy on the biochemical properties and structure of myofibrillar protein from Tegillarca granosa (T. granosa) was investigated. There was no effect of irradiation on the surface hydrophobicity of the myofibrillar protein, however total sulfhydryl content and Ca-ATPase activity both declined to varying extents with increasing irradiation dose.
