Effect of Dense Phase Carbon Dioxide on Micromorphology of Myosin from Litopenaeus vannamei Muscle
摘要
Abstract
In the present research, the effect of dense phase carbon dioxide (DPCD) on the micromorphology of myosin extracted from Litopenaeus vannamei muscle was studied by atomic force microscopy(AFM).DPCD treatments were carried out at different pressures and temperatures for different durations. The aggregation characteristics of myosin during the treatments were explored. The results showed that the degree of myosin denaturation and aggregation varied greatly as a function of pressure, temperature and treatment time. DPCD induced myosin denaturation and aggregation by thermally inducing protein-protein interaction as well as by inducing interaction between the protein and carbon dioxide at high pressure.关键词
