The effect of antioxidants on the quality changes of cuttlefish (Sepia pharaonis) muscle during frozen storage

Evaluation of Thymus vulgaris Extract on Hippocampal Injury Induced by Transient Global Cerebral Ischemia and Reperfusion in Rat

“…During oxidation, endogenous and exogenous oxidants react with saturated fatty acids and produce peroxides which destroy myelin sheath, lipids, genetic material and other membrane components [23].…”

Extraction and characterisation of gelatin from the skin of striped catfish (Pangasianodon hypophthalmus) and studies on its colour improvement

“…Thus, higher H 2 O 2 concentration was necessary for improvement of colour of gelatin. The fish needs to be bleached, because the flesh could be stained by ink, viscera and colour pigments during handling and processing (Thanonkaew et al, 2008 derived from the decomposition of hydrogen peroxide, were able to destroy the chromophore. Hydroperoxyl anion is a strong nucleophile which, during bleaching, is able to break the chemical bonds that make up the chromophore.…”

“…Nevertheless, the pigments in skin may pose a colour problem and bleaching could be performed prior to gelatin extraction. Hydrogen peroxide is a potent oxidant that is widely used as bleaching agent in seafood processing (Kolodziejska et al, 1999;Thanonkaew et al, 2008). Kolodziejska et al (1999) reported that soaking squid skin in 1% H 2 O 2 in 0.01 M NaOH for 48 h could improve the colour of the resulting collagen.…”

Recovery of Gelatin with Improved Functionality from Seafood Processing Waste

“…For removal of the color, bleaching of the skin prior to gelatin extraction has been attempted. Hydrogen peroxide is a potent oxidant that is widely used as a bleaching agent in seafood processing (Thanonkaew et al 2008 ). The functional properties of gelatin from the dorsal and ventral skin of cuttlefi sh with and without bleaching by H 2 O 2 at different concentrations [2 and 5 % (w/v)] for 24 and 48 h were studied.…”
