芘荧光探针应用于狭鳕鱼皮凝胶形成过程的可行性研究
Study on the feasibility of pyrene fluorescence probe applied in the formation of gel from walleye pollok（ Theragra Chalcogramma） skin
摘要
Abstract
The pyrene fluorescence probe was introduced in the formation of elastic gel from walleye pollock （Theragra Chalcogramma） skin. Results showed that the fluorescence intensity and 11/13 ratio of pyrene monomer both increased at first and then decreased in the sol of 6.67% with the increasing of pyrene concentration. The monomeric fluorescence intensity showed its maximum,when pyrene concentration reached 401μmol/L,while the 11/13 ratio had a high level in the range of 20N60μmol/L,and the values were very close. Pyrene Ie/IM ratio increased with the concentration increasing,and was lower in the range of 2-40μmol/L. Considering the three factors mentioned above,pyrene with the concentration of 40μmol/L was employed as the fluorescence probe in the gel formation from walleye pollock skin. The study indicated that pyrene I1/13 ratio could characterize the intermolecular cross-linking in the sol,and the gelatin point was 7h,but IdIM ratio couldn＇t. This 13rovided the important basis to characterize the dynamic formation of other fish skin aels.关键词
