Characteristics and emulsifying properties of structured phospholipids from palm pressed fiber and omega-3 fatty acid concentrates from by-products of fish processing by enzymatic acidolysis.

The synthesis of structured phospholipids (SPLs) containing ω-3 fatty acids was carried out through enzymatic acidolysis reactions using lipase from between palm pressed fiber phospholipids (PPF PL) with four ω-3 fatty acid concentrates as different acyl sources. The purity of SPLs increased compared to original PPF PLs. The degree of ω-3 fatty acid incorporation to the SPLs was different that depended on the sources of acyl.

Optimization of extrusion-assisted extraction parameters and characterization of alginate from brown algae ().

The aim of this research is to investigate the effects of brown algae to solution ratio, feed rate, and pH on the multiple responses of alginate extracted using twin screw extruder. Box-Behnken design was used to find out the optimum extrusion-assisted extraction parameters based on the responses of residence time distribution (RTD), yield, intrinsic viscosity, and molecular weight. The result showed that alginate extrusion-assisted extraction parameters affected on the movement of algae in the screw channel and physicochemical properties of alginate.

The Effect of Phytosterol-Rich Fraction from Palm Fatty Acid Distillate on Blood Serum Lipid Profile of Dyslipidemia Rats.

Phytosterol-rich fraction (PRF) obtained from palm fatty acid distillate (PFAD) was investigated for its effect on blood serum lipid profile of dyslipidemia rats. Dyslipidemia was induced by force feeding cholesterol to five groups of rats; one group was a control or normal group. Cholesterol force-fed groups were treated with 0, 10, 20, 30, and 40 mg PRF/kg/day for 4 weeks.
