Hydrolysis bovine caseins allergy extract of thistle flowers extract clarified of ficin Hydrolyse caséines bovines allergie extrait de fleurs de cardon extrait clarifié de la ficineIndex. décimale : 640 Industrie Alimentaire Résumé : The objective of this work is the hydrolysis of casein bovine by the clarified extract of ficin and the crude extract of thistle flowers in order to study the impact of these on the allergenicity of bovine caseins.
The first part of this work is dedicated to the extraction and characterization of the enzyme content system in each plant (Ficus carica and Cynara cardunculus); the characterization aimed mainly determining the physicochemical characteristics, coagulant activity, proteolytic activity and the determination of the electrophoretic profiles of the studied enzymes. The main results showed
that, in terms of enzymatic activities, the clarified extract of ficin has a coagulant activity of 201.56 UP, and a proteolytic activity of19391.67 µg / ml / h, the cardoon flower extract has coagulant activity of 1.25 U.P and a proteolytic activity of 142.5 µg/ml/h. A second part which aims, the achievement of kinetic hydrolysis of bovine casein by extracts previously prepared and followed by the O-phthaldialdehyde method (OPA) to determine the degree of hydrolysis at each sampling time then a characterization of hydrolysates obtained was conducted
by a method électrophoritique SDS-PAGE. The extract of ficin shows a maximum degree of hydrolysis after 24 hours of58.3 % and 32.91 % for both ratios E / S = 1/100 and 1/1000 respectively, while that of the extract of the flowers of cardoon shows a DH maximum of 24.12 % and 32.42 % for both ratios E/S= 1/100 and 1/50 respectively. From the profiles électrophoritiques we can say that the extract of ficin differs from that of cardoon flowers by a speed faster degradation of caseins and
resulting in their disappearance after 30min ofreaction unlike the extract crude cardoon where caseins persist to 6 hours of hydrolysis.
Finally, the evaluation of immunoreactivity proteolysates after the enzyme treatment was performed by determination of the immuno-electrophoretic profiles by the Western blotting and the result was not sufficient to interpret, and consequently this test necessitate to be repeated and confirmed by other methods. On the other hand, the study of the impact of enzyme extracts on the allergenicity of proteins should be extended to other milk proteins such as whey proteins and other allergenic food proteins.Diplôme : Magistère En ligne : ../theses/agronomie/LAZ6823.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10093 Hydrolyse des caséines bovines par des protéases végétales en vue de réduire leur allergénicité.

In first time, we describe the various optical communications technology particularly that used in multiple access systems (Optical Code Division Multiplexing Access). In the same context, we detailed the different codes proposed in the literature for this type of access technique, including the steps required to generate 2D and 1D code types. The second part is devoted to the study of the concept of generalized quantum walks for WDM applications (Wavelength Division Multiplexing). Starting with the establishment of the state of the art for this type of quantum encryption, and then presents some models studied in the last decades. The third part is divided into two parts. Firstly, we
propose a new family code for the SAC-OCDMA system. Since the concept of the code is
based on the flexible cross-correlation (FCC), is called the 'Modified Flexible Cross
Correlation ' (MFCC). The OCDMA system performance with the proposed code MFCC is
analyzed taking into account the effect of shot noise, noise PIIN and thermal noise. It is noted that the MFCC code is the best in terms of BER compared to MDW and RD codes. Its simplicity in the building code and flexibility in the cross-correlation control makes this code a suitable candidate for future OCDMA systems. Secondly, we study the ability of quantum networks to support both random and non-random data signals over a shared infrastructure.
The effect of the wavelength on the coverage distance with the quantum bit error rate of a QKD system is analyzed. The results of the random phase showed a minimum distance to cover compared with the non-random phase. For the random emission amplitude fluctuation improvement in system performance is achieved. Therefore, we find that the few changes should not degrade significantly the performance of the system, but the mode of sending the data has a significant effect on the channel integrity.
