Kinetics coagulation

Particle Generation Rate. The particle generation rate was calculated from the concentration of k-fold precursor particles assuming Muller coagulation kinetics 2.) as well as including propagation terms.

The six major proteins of milk, asl-, o s2-, and /c-casein, jS-lactoglobulin, and a-lactalbumin, contain at least one tryptophan residue [57], the fluorescence of which allows the monitoring of the structural modifications of proteins and their physicochemical environment during the coagulation processes. Emission fluorescence spectra of the protein tryptophanyl residues were recorded for the milk coagulation kinetics induced by... 

Three types of coagulation were considered. The glucono(5)lactone (GDL)-induced coagulation system (GDL system) was prepared by acidification with 1.75 g/L GDL (Roquette, Lestrem, France). The rermet-induced coagulation system (rennet system) was prepared by the addition of calf rennet (SKW, Baupte, France) at 25.6/rg/L of milk. The GDL-I-rermet-induced coagulation system (mixed system) was prepared by acidification with 0.45 g/L GDL for 2h followed by the addition of rennet at 15.4/ig/L of milk. The experimental conditions for each system were selected in order to achieve gelation without syneresis. Coagulation kinetics were performed at 30°C. 

Fluorescence spectra were recorded using an SLM 4800 spectrofluorimeter (Bioritech, Chamarande, France) fitted with a thermostat-controlled (30°C) front-surface accessory. The incidence angle of the excitation radiation was 60°. Coagulation kinetics were performed in a quartz cuvette 1 cm x 1cm. All spectra were corrected for instrumental distortions in excitation using a rhodamine cell in the reference channel.

In dark-field microscopy, the particles are only a blur no details are distinguishable at all. Some rough indication of the symmetry of the particles is afforded by the twinkling that accompanies the rotation of asymmetrical particles, but this is a highly subjective observation. However, the technique does permit the rate of particle diffusion to be observed. We see in Chapter 2 how to relate this information to particle size and shape. The number of particles per unit volume may also be determined by direct count once the area and depth of the illuminated field have been calibrated. This is an important technique for the study of coagulation kinetics, a topic we discuss in Chapter 13.

The emulgent, phthallylsulfathiazole provides highly stable type of emulsions. Even in the presence of cationic surfactants, these emulsions were found to be reasonable stable. Effect of detergents on the stability was in the order CPB < CPC < CTAB < LPC, which is compatible with their chain length. The rate determining step of coagulation kinetics of the system under investigation is the coalescence as this is slower than flocculation.
