Quality characteristics of spent hen Pectoralis major muscles and effect of NaCl and sodium tripolyphosphate (STPP) on quality changes of raw and cooked spent hen muscles during chilled storage were investigated. Meat from spent hen had nutritional values the same as commercial broiler meat. Treated raw samples with 1.0% NaCl and 10% STPP showed lower drip loss during storage time (P<0.05), and...

The quantitation of intracellular sodium ion concentration [Na+]in perfused organs using NMR spectroscopy requires a knowledge of the extent of visibility of the 23Na resonance and of the intracellular volume of the organ. We have used a multinuclear NMR approach, in combination with the extracellular shift reagent dysprosium (III) tripolyphosphate, to determine the NMR visibility of intra- and...

Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...

Immediately upstream from and adjacent to the oprP gene, which codes for the phosphate-specific porin OprP of Pseudomonas aeruginosa, lies the PR region (oprO), which cross-hybridizes with oprP DNA. To determine the function of this region, the oprO gene was expressed behind the lactose promoter in Escherichia coli, and the resultant OprO protein was purified and reconstituted into planar lipid...

The paper presents the results of the influence of anionic-type detergent containing sodium tripolyphosphate and ethoxylated oleylcetyl alcohol on the type and quantity of present amino acids in the fermentation broths of the fungi Aspergillus niger, Alternaria tenuis and Fusarium oxysporum cultivated on a medium with the addition of 1% detergent as a function of their application in the proces...
