Abstract Cowpea protein isolate (CPI) was subjected to various dry and wet heat pretreatments followed by sequential digestion with pepsin pancreatin; the undigested residues were isolated as indigestible cowpea proteins (ICPs). All ICPs exhibited in vitro bile acid-binding capacity but ICP from slow cooling-induced gelation had highest yield (68%) used for rat feeding experiments determine eff...

Among the methods available to reduce water production, injecting a gelling system composed of a polymer and a crosslinker has been widely used. In this work, a hydrogel was prepared by crosslinking of an aqueous solution containing hexamethylenetetramine (HMTA) as crosslinker, hydrochloric acid (HCl) as an activator, and the co-polymer of 2-acrylamido-2methyl-propanesulfonic-acid sodium salt (...

Background & Aims: In recent years, the feasibility of hydrophilic nanoparticles has been broadly investigated for use in drug delivery and therapeutic systems. Due to the problems of traditional adjuvants, in this study Agkistrodon halys (Ah) Snake venom was loaded in chitosan nanoparticles (CS NPs) in order to be used as an advanced adjuvant and antigen delivery system in ant...

We attempt a classification of different colloidal gels based on colloidcolloid interactions. We discriminate primarily between non-equilibrium and equilibrium routes to gelation, the former case being slaved to thermodynamic phase separation while the latter is individuated in the framework of competing interactions and of patchy colloids. Emphasis is put on recent numerical simulations of col...

biodegradable nanoparticulate carriers, have important potential applications for administration of therapeutic molecules. chitosan based nanoparticles have attracted a lot of attention upon their biological properties such as biodegradability, biocom-patibility and bioadhesivity. the aim of the present investigation was to describe the synthesis and characterization of novel biodegradable nano...

microencapsulation has become a common technique in the production of controlled release dosage forms. many results have been reported, concerning the use of alginate beads as controlled release drug formulations. alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

in recent years, utilization of chitosan /tripolyphosphate nanoparticles has been considered greatly as protein delivery vehicles. effects of a variety of factors on final characteristics of nanoparticles have been studied by many investigators. although, the objective of this study was to achieve smaller chitosan nano carriers via changing fabrication parameters such as ph and temperature and ...
