Thiobarbituric acid reacting substances TBARS

Frankfurters containing 3.3% sodium lactate were also found to have lower microbial counts for lactic acid bacteria than those of a control (Murano and Rust, 1995). Frankfurters manufactured with potassium sorbate and sodium benzoate, at 0.05% and 1.0%, were compared with those containing 3.3% sodium lactate. After addition of 3.3% sodium lactate to the sausage formulations, decreased TBARS (thiobarbituric acid reacting substances) values were found. Storage time was found to affect the product quality and resulted in decreases in textural properties (Choi and Chin, 2003). 

Oleuropein 10 5 M delayed the fall of vitamin E and the formation of TBARS (thiobarbituric acid reacting substances, an index of lipid peroxidation), and the accumulation of lipid hydroperoxides in human LDL oxidized with CuS04 [68]. Other compounds were shown to... 

This test is used for both in vitro and in vivo determinations. It involves reacting thiobarbituric acid (TBA) with malondialdehyde (MDA), produced by lipid hydroperoxide decomposition, to form a red chromophore with peak absorbance at 532 nm (Fig. 10.1). The TBARS reaction is not specific. Many other substances, including other alkanals, proteins, sucrose, or urea, may react with TBA to form colored species that can interfere with this assay.
