Abstract :

Collagen has been used in a wide range of applications in health pharmaceutical and cosmetic industries. White jellyfish (Lobonema smithi Mayer) are edible after brining with salt, blooming every year in the bay of Thailand, has become a new natural source of collagen for using in health products industries. This project aims to study the extraction process of collagen from the white jellyfish in order to get rid of its fishy odour. The processes were used pepsin to extract collagen from fresh (CF) and brining with salt (CB) of White jellyfish. The result showed that the CB gave 39.2% yield of collagen which was higher than CF, 22.2%. The characteristic of collagen base on HPLC and 1H-NMR techniques exhibited that all collagen contained high content of glycine, glutamic acid, alanine and proline. FT-IR spectra pattern of CB presented the strong signal of peak at 1,543.66 cm-1 (Amide II) whereas CF gave that of weak peak. To confirm of collagen type by using sodiumdodecyl sulfatepolyacrylamide gel ellectrophoretic patterns and FT-IR spectra, indicated that both of collagen CB and CF are in the collagen type I. Moreover, CB possessed lower level of fishy smell than CF. From the results could suggest that the white jelly fish should be brined with salts for extraction and pepsin was the suitable process for collagen extraction in this experiment. Further works will focus on toxicity of collagen extracted from fresh and brined white jelly fish.
