Clove (Syzigium aromaticum) is a spice plant which commonly used as raw material in cigarette, food and beverage, pharmaceutical, perfume insecticide industries. All parts of the clove contain essential oils. However, Sipora District, Mentawai Islands, who have majority plantation businesses was use flower part only. Fallen leaves with potential 15.9 tons/week only become waste. Therefore, this...

Using advanced electron paramagnetic resonance techniques (EPR), oxidation of crude vegetable oils and their components (fatty acids and triglycerides) by radicals generated from hydrogen peroxide was investigated. The correlation rotational times were determined allowing us to characterize radicals formed during edible oils oxidation. Additionally 1H- and 14N-hyperfine coupling constants diffe...

Okara, soybean waste from tofu and soymilk production, was utilised as a natural antioxidant in soap formulation for stratum corneum application. D-optimal mixture design was employed to investigate the influence of the main compositions of okara soap containing different fatty acid and oils (virgin coconut oil A (24-28% w/w), olive oil B (15-20% w/w), palm oil C (6-10% w/w), castor oil D (15-2...

Fossil fuel shortage is a major challenge worldwide. Therefore, research is currently underway to investigate potential renewable energy sources. Biodiesel is one of the major renewable energy sources that can be obtained from oils and fats by transesterification. However, biodiesel obtained from vegetable oils as feedstock is expensive. Thus, an alternative and inexpensive feedstock such as wa...

Pseudomonas oleovorans NCIMB 6576 and Ralstonia eutropha 10442 were used for the production of Polyhydroxyalkanoates (PHA) from industrial waste cooking oils, bacteria cultured on tryptone soya broth (TSB) Tryptone agar (TSA). P. NCIMB6576 gave a better percentage PHB yield (8.2%) with PS oil as carbon source compared to 6.45% TS oil. However, very low (0.64%) was recorded when grown TSB withou...

Dependence on fossil fuels for meeting the growing energy demand is damaging world’s environment. There a dire need to look alternative that are less potent greenhouse gas emissions. Biofuels offer several advantages with harmful effects Biodiesel synthesized from organic wastes produced extensively like edible, non-edible, microbial, and waste oils. This study reviews feasibility of state-of-t...

Polyurethanes are most often called “green” when they contain natural, renewable additives in their network or chemical structure, such as mono- and polysaccharides, oils (mainly vegetable oils), polyphenols (e.g., lignins, tannins), various compounds derived from agro-waste white biotechnology (Principle 7). This usually results these polyurethanes obtained less hazardous substrates 4). Approp...

• A review of waste fats, oils and greases (FOGs) enzymatic hydrolysis is carried out. Waste FOGs potential industrial interest as oleochemical feedstock are described. Main challenges on the residual lipids explained. Developments lipase immobilization, combination, engineering revised. Intensification processes for The increasing global generation oils, resulting in a cascade economic, enviro...

Among the Sicilian economic productive sectors, that of wine production has today a considerable value. However, with growth this sector, notable was increase in waste, which to date is not only an damage for companies, but also threat environment. It known waste from properties (e.g., antioxidants) have potential reuse at cosmetic, pharmaceutical and nutritional levels obtain economically sust...
