Rbd Palm Olein-based Methyl/ethyl Esters
In this study, transesterification of refined, bleached and deodorized (RBD) palm olein was carried out with methanol, ethanol and their mixtures at various methanol/ethanol ratios, while maintaining the molar ratio of oil to alcohol at 1:6. Potassium hydroxide was used as the catalyst. The process variables were temperature, methanol/ethanol molar ratio and amount of catalyst. The optimum biod...
متن کاملtert-Butylhydroquinone (tBHQ) protects hepatocytes against lipotoxicity via inducing autophagy independently of Nrf2 activation.
Saturated fatty acids (SFAs) induce hepatocyte cell death, wherein oxidative stress is mechanistically involved. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a master transcriptional regulator of cellular antioxidant defense enzymes. Therefore, Nrf2 activation is regarded as an effective strategy against oxidative stress-triggered cellular damage. In this study, tert-butylhydroquinone ...
متن کاملAntibacterial activity and mode of action of tert-butylhydroquinone (TBHQ) and its oxidation product, tert-butylbenzoquinone (TBBQ).
OBJECTIVES The antioxidant tert-butylhydroquinone (TBHQ) is a food additive reported to have antibacterial activity, and may therefore have application in the healthcare setting. This study sought to characterize the antibacterial activity and mode of action of TBHQ and its oxidation product, tert-butylbenzoquinone (TBBQ). METHODS The stability of TBHQ/TBBQ was studied in buffer. Susceptibili...
متن کاملPalm oil and palm olein frying applications.
Several million tones of palm oil and palm olein are used annually in the world for frying. This paper will discuss their frying performances in three major applications - industrial production of potato chips/crisps, industrial production of pre-fried frozen French fries and in fast food outlets. In the first study, about four tones of potato chips were continuously fried 8 hours a day and fiv...
متن کاملtert-butylhydroquinone (tbhq) improves antioxidant status in rat tissues following chronic diazinon intoxication
considering that the involvement of oxidative stress has been implicated in the toxicity of organophosphate insecticides, the objective of the present study was to investigate antioxidants and oxidative stress markers in the liver and kidney of wistar rats treated with chronic doses of diazinon. in addition, the effect of tert-butylhydroquinone (tbhq), a food-additive antioxidant, on attenuatio...
