    Abstract:      豬皮膠原蛋白(pig skin collagen )經三偏磷酸鈉(sodium trimetaphosphate , STMP)予以磷酸化製成水溶性之磷酸化豬皮膠原蛋白(phosphorylated pig skin collagen, PPSC)後,續以此為基質,添加木瓜酵素(1g/100g基質)與白胺酸已 酯(leucine hexyl ester, leu-OC?腹^(0.03MOL/100基質)於pH 9,37℃下反應 30min 後,幾近全部之白胺酸己酯可被導入PPSC之α?紐儥珘搳A而製成具極優良 乳化性與起泡性之磷酸化豬皮膠原蛋白酵素修飾物(phosphorylated pig Skin collagen-leu-OC??,PPCS-leu-OC?腹^。生產此1Kg PPCS-leu-OC?萱珨搷鰹?言? 約356元,若將木瓜酵素用量減半,而白胺酸己酯減為原來2/3時,則約可降低成 本1/4,但反應時間需延長至90min。
         The pig skin collagen was treated with sodium trimetaphosphate( STMP) and then incubated with papain ( 1g/100g protein and leucine hexyl ester ( leu-OC ?腹^( 0.03mol/100g protein ) at pH 9, 37 ℃ for 30min. Almost all of leu-OC ?? were in- corporated onto the C-terminal of α?? chain in phosphorylated pig skin collagen ( PPSC ). The final product PPCS-leu-OC ?? had excellent functionalities and was suitable for use as a low-fat content proteinaceous surfactant. The computed cost of materials for manufacturing of one kg of PPSC-leu- OC ?? from pig skin was about NT$ 356, but if the consumptions of papain and leu-OC ?? were adjusted to half and to 2/3 of original amount, respectively, and with the increased the reaction time to 90min, the cost might reduced another 25 %.
