This experiment is an investigation of used cooking oil as a sustainable and renewable resource for methyl ester production. with more than 95.5% production yield, thermally activated hydrated cement has been carefully discussed as a catalyst in the transesterification of used cooking oil into methyl ester to use waste cement as a heterogeneous catalyst for methyl ester production through elect...

Converting waste cooking oil into biofuel represents a three-win solution, dealing simultaneously with food security, pollution, and energy security. In this paper, we encode the policy documents of waste cooking oil refining biofuel in China based on content analysis, and explore the related policies from the two dimensions as basic policy tools and enterprises supply chain. Research indicates...

BACKGROUND In sub-Saharan Africa, more than 42% of children are at risk for vitamin A deficiency, and control of vitamin A deficiency will prevent more than 600,000 child deaths annually. In the West African Economic and Monetary Union (UEMOA), an estimated 54.3% of preschool-age children are vitamin A deficient and 13% of pregnant women have night blindness. OBJECTIVE To project the achievem...

Seasame oil is the most stable vegetable oil against oxidation. It has been revealed that the oxidative stability of seasame oil is due to the lignans such as sesamole, sesamilinol, pynoresional, sesaminol, etc., contained in it. Sesamol is obtained by the hydroxylation of sesamolin. The reaction is hydroxylation which is generally promoted by acid and heat. The changes of the concentration of ...

Consumption of repeatedly heated cooking oil (RHCO) has been a regular practice without knowing the harmful effects of use. The present study is based on the hypothesis that, heating of edible oils to their boiling points results in the formation of free radicals that cause oxidative stress and induce damage at the cellular and molecular levels. Peroxide value of heated oil, histopathological a...

BACKGROUND Olive oil is a major component of the Mediterranean diet suggested to be beneficial to counteract Alzheimer's disease. AIM OF THE STUDY Our objective was to examine the association between olive oil use, cognitive deficit and cognitive decline in a large elderly population. METHODS We followed 6,947 subjects with a brief baseline food frequency questionnaire and repeated cognitiv...

We entrapped lipase from Pseudomonas cepacia in polyallylamine-mediated biomimetic silica, and then applied entrapped lipase to the synthesis of biodiesel with soybean oil or waste cooking oil as a feedstock. The effects of reaction temperature, substrate molar ratio (methanol/oil) and n-hexane content (w/w of oil) were evaluated using response surface methodology (RSM) combined with Box-Behnke...
