초록
Recently, many researchers have studied silk sericin because of its high water retention, good wound healing, good cyto-compatibility, and blood-glucose- and cholesterol-lowering effects. Although sericin film can be used in wound dressing and cosmetic packs, its poor mechanical properties have prevented its use in industrial fields. In the present study, sericin was obtained from different silkworm varieties, and the effect of silkworm variety on the structure and properties of sericin was examined. Except for a small difference in serine content, no significant difference in sericin was noted among the silkworm varieties. In addition, silkworm variety almost had no effect on solution viscosity, implying that it does not influence the molecular weight of sericin. Mechanical properties of sericin film were strongly affected by silkworm variety. Wonwon 126 showed the best mechanical properties, while N74 and Geumgwangju displayed the worst properties
