Micro-Encapsulation for Pigment Surface Modification

Synthesis and Surface Modification of Pigment Red 3 by Sulfonation Method for Improving Properties in Waterborne Ink

Pigment Red3 was synthesized and chemically treated by sulphonation. The treatment, affected the surface chemistry and the shape of pigments. The effects of reaction time, temperature, Solvent/Pigment ratio and Acid/Pigment ratio were examined on the treated pigment. The investigation of experimental design based on Tauguchi method, was carried out. To assessment of treated particles, UV-visibl...

Surface modification for titanium implants by hydroxyapatite nanocomposite

Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...

Taste Masking of Azithromycin By Micro Encapsulation

Undesirable taste is one of several important formulation problems that are encountered with certain drugs. The problem of bitter and obnoxious taste of is a challenge to the pharmacist in the present scenario. Several oral pharmaceuticals and bulking agents have unpleasant, bitter-tasting components. The desire of improved palatability in these products has prompted the development of numerous...

Probiotication of Tomato and Carrot Juices for Shelf-life Enhancement using Micro-encapsulation

ABSTRACT: This study was aimed at probiotication of tomato and carrot juices using Lactobacillus plantarum, Lb. fermentum, Lb. casei, Lysinibacillus sphaericus and Saccharomyces boulardii. To enhance the stability, the probiotic cultures were micro-encapsulated using alginate coated chitosan beads. Tomato and carrot juice samples were pasteurized for 20 min at 63 °C. Lb. fermentum, Lb. plantara...
