This study aimed to evaluate the quality of selected oils from seeds herbs and vegetables (basil, fenugreek, coriander, tomato, garden cress, parsley, dill), especially their oxidative stability. The were tested for oxidation degree (acid value, peroxide p-anisidine TOTOX indicator, specific extinction under ultraviolet light), colours, content carotenoid chlorophyll pigments, fatty acid compos...

Different biological sources of n-3 polyunsaturated fatty acids (n-3 PUFA) in mainstream commercial products include algae and fish. Lipid oxidation in n-3 PUFA-rich oil is the most important cause of its deterioration. We investigated the kinetic parameters of n-3 PUFA-rich oil during oxidation via Rancimat (at a temperature range of 70~100 °C). This was done on the basis of the Arrhenius equa...

Borage (Borago officinalis L.) is a typical Spanish plant. During processing, 60% are leaves. The aim of this work is to model and optimize the extraction of polyphenol from borage leaves using the response surface method (RSM) and to use this extract for application in emulsions. The responses were: total polyphenol content (TPC), antioxidant capacity by ORAC, and rosmarinic acid by HPLC. The ...

Family Planning Perspectives ceding injection—even if she receives her next injection only a few days late. She must then “restart” the method, even though her last DMPA injection may still be protecting her from pregnancy. Moreover, if all contraceptive users were categorized according to what they report to be their current method, and according to their adherence to that method’s regimen (an...

The aim of the current research work was to assess and compare impact two extraction techniques on physico-chemical, antioxidant parameters grape seed oil (GSO). GSO extracted by Soxhlet Folch methods indicated a notable variation in yield (8.58 % 10.19%) saponification value (196.35 189.33 mg KOH g-1), respectively. However, no significant (p<0.05) detected for density, acid value, refracti...

We provide new fish oil product results to assist industry in Australia and New Zealand and, ultimately, consumers in understanding the high product quality assurance protocols in place, together with the high product quality that has been determined by both industry and independent laboratories. Fish oil capsule products common to Australia and New Zealand were purchased in May 2016 in Richmon...

Marine omega-3 rich oils are used by more than a third of American adults for a wide range of purported benefits including prevention of cardiovascular disease. These oils are highly prone to oxidation to lipid peroxides and other secondary oxidation products. Oxidized oils may have altered biological activity making them ineffective or harmful, though there is also evidence that some beneficia...

In this study, in order to introduce natural antioxidative vegetable oil in food industry, the kolkhoung hull oil and kernel oil were extracted. To evaluate their antioxidant efficiency, gas chromatography analysis of the composition of kolkhoung hull and kernel oil fatty acids and high-performance liquid chromatography analysis of tocopherols were done. Also, the oxidative stability of the oil...

The 2002 National Survey of Family Growth reported that 5.3% of all US women aged 15 through 44 currently using contraception used DMPA.1 Among contraceptors, 13.9% of those aged 15 to 19 and 10.1% of those aged 20 to 24 currently used DMPA compared with 1.6% of those aged 40 to 44.1 Decreasing rates of adolescent pregnancy between 1995 and 2002 are considered to be due in part to increased use...

This paper reports the isolation of phenoloxidase-negative mutants of the white-rot fungus Phanerochaete chrysosporium and the results of a survey of idiophasic functions among these mutants. The mutant strains were isolated from a medium containing o-anisidine after gamma irradiation of wild-type spores and fell into four classes, divided by the manner in which they mineralized 14C-lignin whea...
