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;...

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...

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...

A selectively cross-linking method, which is based on the ‘‘di–diol” interaction between poly(vinyl alcohol) and borate and the strong electrostatic interaction between chitosan and tripolyphosphate, was developed. Chitosan/poly(vinyl alcohol) films cross-linked separately with borate, tripolyphosphate and borate/tripolyphosphate were then prepared in terms of this method. Water vapor permeatio...

Electrospray ionization mass spectrometry (ESI-MS) was applied for the characterization of inorganic polyphosphates [orthophosphate, pyrophosphate, tripolyphosphate, trimetaphosphate, and tetrapolyphosphatel. The high selectivity of ESI-MS allows the detection of different polyphosphate species without preseparation by ion chromatography or capillary electrophoresis. Furthermore, ESI-MS does no...

Introduction: Curcumin is a water-insoluble agent with some anticancer and antimicrobial effects; while, solubility is essential for a medicine to reach target cells. This study set out to use chitosan tripolyphosphate nanoparticles (CTN) for making curcumin water-soluble, and delivering the required dosage of it to target cells. ...

the chitosan nanoparticles used widely as a drug delivery systems recently. in the present study the echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. the nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. the particles were spherical in shape and th...
