The Jaff#{232} reaction, used to determine creatinine in urine and plasma or serum, givesa positiveerror in the latter becauseof the interference of noncreatinine. In man (particularly children) endogenouscreatinine normally occurs at a relatively low concentration in serum (0.3-1.0 mg./100 ml.). The analytic error contributed by noncreatinine chromogens,therefore, may be considerable. Of vario...

In this study , Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by ...

Food colorants are important in food selection because they improve the gastronomic appeal of foods by improving their aesthetic appeal. However, after prolonged use, many turn toxic and cause medical problems. A synthetic azo-class dye called carmoisine gives meals a red color. Therefore, determination samples is great importance from human health control. The current work was developed to syn...

Synthetic food colours are used worldwide to avoid the loss of original colour in processed foods, as well as to make the products more attractive to consumers. Synthetic food colours are considered superior to natural food colours in terms of their colour value, uniformity, and applicability in various processed foods. Synthetic food colours have been authorized and regulated for use in food a...

-Forensic science laboratories in Maharashtra state regularly receiving number of duplicate foreign liquor samples under section 420 of IPC Act. The study was under taken to confirm these samples as per specifications of the manufacturer. It was found that illegal syndicates adjusted the percentage of alcohol up to standard specific value and used substandard coloring, flavoring and essential o...

The question of whether food additives such as preservatives, artificial flavorings, and artificial colorings trigger hyperactivity has been debated for more than 30 years. Research generally has not supported food additives as influencing hyperactivity—whose characteristics include overactivity, inattention, and impulsive behaviors, traits that in extreme forms define attention deficit/hyperac...

The chemical nature of the important new chromogen ABTS [2,2'-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid)] is described together with an account of the redox and spectroscopic properties of the system ABTS--H2O2--peroxidase. Keq. is calculated and a study of the steady-state kinetics over a whole range of substrate concentrations is reported. By using novel methods of kinetic analysis, a...

Three simple and sensitive visible spectrophotometric methods (A, B, and C) have been developed for the quantitative estimation of mesalamine in bulk drug and pharmaceutical dosage forms. Methods were based on the formation of colored chromogens, which were measured at 552 nm, 440 nm, and 494 nm, respectively. The results obtained with the proposed methods were found to be unsatisfactory with t...
