Mar 01 2018The characterization of microparticles proved an interaction between GSH and the polymers and a microencapsulation of the active compound as well as an improvement of the molecule thermal stability β-CD was more efficient for encapsulating GSH allowing the slow release of the molecule into wine model solution and added protection of the

The starch microparticles showed three stages of weight loss at 27 C 120 C 170 C the large mass loss was found in the temperature range from 120 C - 270 C values lower than those found in native starch this is due to the loss of crystallinity as a consequence of the treatments used to obtain them in addition this fact indicates

The forming conditions of biodegradable polymer films containing iodine-modified starch particles as well as the properties of the obtained films were investigated Cationic cross-linked starch microparticles and cationic starch nanoparticles were dispersed in cellulose acetate and hydroxyethyl cellulose solution respectively and composite films were spin-casted

The water-in-oil (W/O) emulsification-diffusion method was used for construction of keratin (Ker) alginate (Alg) and Ker/Alg blend microparticles The Ker Alg and Ker/Alg blend solutions were used as the water phase while ethyl acetate was used as the oil phase Firstly different concentrations of Ker solution was used to find suitable content 1 6#x0025 w/v Ker solution was blended

Oral vaccination against diphtheria using polyacryl starch

Biodegradable polyacryl starch microparticles were used as a mucosal adjuvant Diphtheria toxin or cross-reacting material of diphtheria toxin (CRM197) was covalently conjugated to the microparticles and fed to mice by oral gavage Formaldehyde treatment was also studied as a means of either detoxifying (diphtheria toxin) or stabilising (CRM197
