This work is concerned with polyethylene terephthalate (PET) saponification by different potassium compounds in various polyols as well biodiesel’s main by-product, crude glycerol. It was established that reaction conditions (initial PET/K+ molar ratio, time, etc.) could control the molecular weight of obtained oligomeric products. In ethylene glycol, depolymerization proceeds rapidly, and alre...

context periodontal plastic surgery can help people improve their lives by addressing aesthetic parameters of their smile. much of what comprises a beautiful and appealing smile is influenced by emotion and personality; however, many structural elements of a smile can be improved through surgical intervention. evidence acquisition the end result often lends significant support to people who wis...

Rice bran oil, non conventional oil was blended with six traditional oils in the ratio of 70:30 and 80:20 for the enhancement of its market acceptability and awareness in consumers regarding its use in cooking. Effect of deep-fat frying on these blends was studied by assessing the changes in percent fat absorption and physicochemical properties during repeated frying process (three times). The ...

Production of carotenoids and lipids by Rhodotorula toruloides CBS 14 cultivated on wheat straw hydrolysate was investigated. An ultra-high-performance liquid chromatography (UHPLC) method for carotenoid quantification developed validated. Saponification effects individual were identified, lipid kinetics during cultivation determined. The β-carotene, γ-carotene, torularhodin, torulene identifie...

The effects of frying unripe plantain and sweet potato (separately) in soyabean oil on the properties of the oil were investigated. Also, the effect of the degradation of the oil on biodiesel yield obtained from the oil was considered. Physico-chemical properties of soyabean oil (acid value, saponification value, viscosity, density, colour) were measured daily after being used for frying for da...

Cholesterol has been used to monitor artifact generation. Stability differences among cholesterol oxide products (COPs) and cholesterol in thermal and alkaline conditions are theorized. Thus, use of cholesterol may be unsuitable for detection of artifacts generated from COPs. Stability of cholesterol was compared to that of 7-ketocholesterol (7-keto) and β-sitosterol (βS) under various thermal ...

The study reports the alternative use of non-edible fermented olives for production high-quality natural soaps with a fast process, low environmental impact, and without preliminary treatments raw material. Damaged olives, not used as food, were naturally oil was extracted by mechanical extraction. product obtained human consumption due to its high acidity, but it had content peroxides. olive a...
