SINTESIS FOSFOLIPID MENGANDUNG ASAM LEMAK w-3 DARI FOSFOLIPID KEDELAI DAN MINYAK KAYA ASAM LEMAK w-3 DARI HASIL SAMPING PENGALENGAN TUNA (original) (raw)

The superiority of soy phospholipids could be obtained by incorporation of w-3 fatty acids into phospholipids structure,especially EPA (eicosapentaenoic acid, C20:5w-3) and DHA docosahexaenoic acid, C22:6w-3). Structurization ofcommercial soy phospholipids was conducted by replacement of natural fatty acids in soy phospholipids by w-3 fattyacids from w-3 fatty acids enriched Þ sh oil from tuna canning processing using enzymatic acidolysis. Two factors werestudied in enzymatic acidolysis, concentration of R. miehei lipase and time of reaction. The result showed that increasingreaction time tended to decrease degree of EPA and DHA incorporation at low enzyme concentration. Meanwhile, thereaction time did not affect degree of incorporation at high enzyme concentration. DHA incorporation was higherthan EPA that obtained structured phospholipids is supposed to be suitable for high DHA food products. There was apreference of EPA and DHA to incorporate into phosphatidylethanolamine structu...
