Phospholipids and their partial hydrolysates, namely lysophospholipids (LPLs), have been widely used in food, pharmaceutical, and cosmetic products as highly efficient emulsifiers. This study was conducted to produce @entity4600 ( @entity4601 )-esterified LPLs by enzymatic modification of phospholipids obtained from the head of autumn @entity5661 ( @entity5661 ). The emulsifying properties of the obtained LPLs were also evaluated. Two different types of substrates of salmon head phospholipids were prepared via @entity13918 and cold @entity1324 precipitation. Enzymatic partial hydrolysis was carried out using immobilized phospholipase A1 (PLA1) and Lipozyme RM IM. Results showed that the increase in @entity4601 in the LPLs was much higher in the @entity3440 -separated phospholipids than in the @entity1324 -precipitated phospholipids. When @entity3440 -separated phospholipids were used as the substrate, the @entity4601 content of the LPLs increased from 23.1% to 40.6% and 42.6% after 8 h of partial hydrolysis with Lipozyme RM IM and immobilized PLA1, respectively. The yield of the LPLs was comparatively higher in the Lipozyme RM IM than in the immobilized PLA1 hydrolysis reaction. The critical micelle concentration values of the LPLs and purified @entity6579 ( @entity15002 ) were 100 mg/L and 5 mg/L, respectively. The surface tension values of the LPLs and @entity15002 were reduced to 30.0 mN/m and 30.5 mN/m, respectively. The hydrophilic-lipophilic balance of the LPLs and @entity15002 were 6.0 and 9.4, respectively. Based on the emulsifying properties observed, we conclude that LPLs derived from the phospholipids of salmon head lipids could be used as a health-beneficial emulsifier in the food industry.
