Olein Oil

Palm oil is the most abundant of all oils produced globally. It is very high in saturated fatty acids specifically palmitic acid, but other fatty acids (monounsaturated (MUFA) and polyunsaturated) are presented at low concentrations. In the processing plant some high amount of oleic acid with some other unsaturated fatty acids are extracted and marketed as Palm olein oil, and used to reduce blood or egg cholesterol (Rievelles et al., 1994). The objective of this study was to determine the optimum level of dietary palm olein oil required to enrich the mono-unsaturated fatty acid content of yolk, egg cholesterol and antibody titre.

Myocardial Ischemia And Reperfusion

Reactive oxygen species induce myocardial damage after ischemia and reperfusion in experimental animal models. Numerous studies have investigated the deleterious effects of ischemia-reperfusion (I/R)-induced oxidant production using various pharmacological interventions. More recently, in vitro studies have incorporated gene-targeted mice to decipher the role of antioxidant enzymes in myocardial reperfusion injury. We examined the role of cellular antioxidant enzymes in the pathogenesis of myocardial I/R (MI/R) injury in vivo in gene-targeted mice. Neither deficiency nor overexpression of Cu-Zn superoxide dismutase (SOD) altered the extent of myocardial necrosis. Overexpression of glutathione peroxidase did not affect the degree of myocardial injury. Conversely, overexpression of manganese (Mn)SOD significantly attenuated myocardial necrosis after MI/R. Transthoracic echocardiography was performed on MnSOD-overexpressing and wild-type mice that were subjected to a more prolonged period of reperfusion. Cardiac output was significantly depressed in the nontransgenic but not the transgenic MnSOD-treated mice. Anterior wall motion was significantly impaired in the nontransgenic mice. These findings demonstrate an important role for MnSOD but not Cu/ZnSOD or glutathione peroxidase in mice after in vivo MI/R.

Carotenoids in red palm olein oil (RPOOO) have been scientifically proven to have good functional properties for the human health so that RPOOO has the potential to be used as one of the healthy drinks. One of the problems faced in the use of RPOO as a health drink is the taste and aroma is less interesting. This study aims to obtain the ratio of  RPOO and salak sidempuan extract used to obtain stable emulsion, acceptable  viscosity, and acceptable   emulsion product.    Four emulsions  were prepared using 1% carbonmethylcellulosa as emulcifier and four different composition ratios of RPOO and salak extract were prepared. Emulsions characteristics and their sensory acceptability were investigated.  The results of this study showed that the ratio of RPOO ratio and 1: 2  salak extract obtained the best stability with viscosity of 175 cP emulsion. In addition, emulsions with an RPOO ratio and 1:25 salak extract yield preferable levels of sensory attributes such as color, aroma and taste.

The present study was designed to develop safer, effective, and viable cardioprotective herbal combination to control oxidative stress related cardiac ailments as new alternatives to synthetic drugs. The synergetic cardioprotective potential of herbal combination of four plantsT. arjuna(T.A.),P. nigrum(P.N),C. grandiflorus(C), andC. oxyacantha(Cr) was assessed through curative and preventive mode of treatment. In preventive mode of treatment, the cardiac injury was induced with synthetic catecholamine (salbutamol) to pretreated rabbits with the proposed herbal combination for three weeks. In curative mode of treatment, cardiotoxicity/oxidative stress was induced in rabbits with salbutamol prior to treating them with plant mixture. Cardiac marker enzymes, lipids profile, and antioxidant enzymes as biomarker of cardiotoxicity were determined in experimental animals. Rabbits administrated with mere salbutamol showed a significant increase in cardiac marker enzymes and lipid profile and decrease in antioxidant enzymes as compared to normal control indicating cardiotoxicity and myocardial cell necrosis. However, pre- and postadministration of plant mixture appreciably restored the levels of all biomarkers. Histopathological examination confirmed that the said combination was safer cardioprotective product.

The objective of the study was to evaluate the changing pattern of free fatty acid (FFA) and smoke pints of packaged and standard palm olein oil in frying kerupuk jalin. The other objective was to determine the end use of both frying oils during deep fying of kerupuk jalin.  Continous deep frying with three replicates had been done for10 hours using special grade and regular frying oil without the addition of fresh oil during frying study.  The result indicated that The FFA content of both packaged and regular oils increased linearly with increasing frying time, up to 10 hours.   In addition, smoke point of the oils decreased linearly with increasing frying time.  Based on FFA of the oil, the packaged oil could last 1,4 longer than regular oil during frying of kerupuk jalin.
