conclusions diclofenac-loaded nanoparticles based on properties of chitosan gelation could delay the release of drugs in the stomach and be further evaluated for the enteric delivery of diclofenac. objectives the aim of this study was to prepare and evaluate diclofenac-loaded chitosan nanoparticles based on the ionotropic gelation method. materials and methods chitosan (cs) nanoparticles contai...

The Food and Drug Administration is responsible for regulating the use of polyphosphates in seafood. Sodium tripolyphosphate is the most commonly used polyphosphate in the processed shrimp industry; and current regulations limit its use in accordance with Good Manufacturing Practice. The potential exists for economic fraud through mislabeling or excessive use of tripolyphosphate. At this point;...

the present study deals with the formulation and evaluation of chitosan nanoparticles containing donepezil hydrochloride for the targeted delivery to the brain. nanoparticles were prepared by ionic gelation method using sodium tripolyphos-phate (tpp) as a cross linking agent followed by sonication. nanoparticles were obtained in the average size ranging from 116.8 to 227.5 nm. particle morpholo...

This study explores the potential application of rice bran (agro waste) to nano-encapsulate phytase, which is a thermally unstable biologically active enzyme. Rice bran was converted to nanofibers (20-50 nm in diameter) using electrospinning. After optimizing the pH, viscosity, voltage and the distance between electrodes for electrospinning, phytase enzyme was encapsulated and the fibers were c...

Abstract:With glucose as the starting material, sodium tripolyphosphate as the phosphorus acylating agent, and urea as the catalyst, glucose 1-phosphate was synthesized and its properties were analyzed. The synthesis conditions were selected according to the phosphorus content and optimized through the response surface methodology (RSM), based on a 3-level, 3-variable Box–Behnken experimental d...

A complex mixture of fluoro-polyphosphates (FPPs) and polyphosphates was prepared by heating a mixture of NaF and sodium tripolyphosphate (STPP) at 600 8C in nitrogen atmosphere. Two-dimensional P–F heteronuclear correlation spectroscopy (HETCOR) NMR was developed in identifying the atomic connection between F and P in the mixed FPPs. F, P and P–P correlation spectroscopy (COSY) NMR methods wer...

The objective of the study was to establish a pink threshold and simulate the pink defect in cooked chicken breast meat with treatment combinations that would induce significant changes in the color of raw and cooked meat. The subjective pink threshold used in judging pink discoloration was established at a* = 3.8. Samples of three color groups (normal, lighter than normal, and darker than norm...

In this work, we synthesized a chitosan-activated carbon composite (Cs–C) using sodium tripolyphosphate (STTP) as crosslinker and it was evaluated for the adsorptive removal of RBBR dye showing excellent capacity 540.3 mg g −1 .

Enhancing and understanding the tenderness of beef has been an on-going research topic. Recently, injection of compounds into fresh beef muscle is an active area of research. In this preliminary study, four cows of E maturity were the source of eight strip loins. The steaks from the strip loins were split into treatment groups and injected at 24 hours postmortem to a 10% level (v/w) with one of...

The effect of three chemical formulationstwo surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Dodecyl Benzene Sulfonate (SDBS) and a builder Sodium Tripolyphosphate (STPP) on two aquatic plants – Azolla pinnata and Hydrilla verticillata was studied at various concentrations for a period of five months, from November to March. It was observed that while the detergents favoured the growth of p...
