The thiobarbituric acid (TBA) reaction in foods: a review.
The wide diffusion of 2-thiobarbituric acid (TBA) in the scientific literature is due to the TBA assay, or TBA test, which has been employed in the determination of autoxidative alterations of fats and oils. Two processes occur in autoxidation, generally: the free radical and the photo-oxidation mechanisms. The better studied is the free radical mechanism. The hydroperoxiepidioxides and bicyclo...
متن کاملElectrochemical Study of Iodide in the Presence of 2-Thiobarbituric Acid-Catalytic Determination of 2-Thiobarbituric Acid
Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...
متن کاملReaction of linoleic acid hydroperoxide with thiobarbituric acid.
The linoleic acid hydroperoxide obtained by enzymatic peroxidation of linoleic acid was found to react with thiobarbituric acid to yield a red pigment. The optimum pH for the reaction was found to be 4.0. In the early stages of peroxidation of linoleic acid, thiobarbituric acid value, the amount of conjugated diene, oxygen consumption, and peroxide value were in parallel with one another. The d...
متن کاملAnalysis of visible reflectance spectra of stored, cooked and diseased chicken meats.
Visible spectra of cold stored, cooked, and diseased chicken meats were collected. Changes in ratios of R(1)=A(485 nm)/A(560 nm) and R(2)=A(635 nm)/A(560 nm,) which are related to absorbances of the bands at 485 (metmyoglobin), 560 (oxymyoglobin), and 635 nm (sulfmyoglobin), were observed to be useful for studying the variation of meat color under the conditions of cold storage and cooking proc...
