Kinetic study of soybean pure powder lecithin hydrolysis using immobilized phospholipase A₂

Soybean Oil Degumming by Immobilized Phospholipase A1

In the present study, we investigated the ability of an immobilized phospholipase A1 (PLA1) in degumming of soybean oil. The enzyme was immobilized by simple adsorption on bentonite without any further modification. The free and immobilized PLA1 were characterized by Fourier Transform InfraRed (FT-IR) spectroscopy and X-Ray Diffraction (XRD). The immobilizat...

Stability of soybean oil degumming using immobilized phospholipase A(2).

The aim of this study was evaluation of stability of immobilized phospholipase A2 (PLA2) for soybean oil degumming. Also, the effect of reaction time on residual phosphorus levels was investigated according to the optimum pH and temperature. The free PLA2 and three immobilized PLA2 demonstrated significant differences in optimum operation conditions. pH, temperature and reaction time increased ...

Studies on the hydrolysis of lecithin by a Penicillium notatum phospholipase B preparation.

Optimization of continuous hydrogenation of soybean lecithin using factorial design

Soybean lecithin containing a mixture of phospholipids (PLs) is an important co product obtained during soybean oil refining. Saturated rich PLs find several applications in food, cosmetic and pharmaceutical areas. The present study reports a simple, rapid, efficient and continuous hydrogenation process using 10% Pd/C catalyst at various temperatures and pressures. Degree of hydrogenation was m...

Kinetic evaluation of cell membrane hydrolysis during apoptosis by human isoforms of secretory phospholipase A2.

Some isoforms of secretory phospholipase A(2) (sPLA(2)) distinguish between healthy and damaged or apoptotic cells. This distinction reflects differences in membrane physical properties. Because various sPLA(2) isoforms respond differently to properties of artificial membranes such as surface charge, they should also behave differently as these properties evolve during a dynamic physiological p...
