Waste oil industry has a great potential use, as 77% oil yield are an untapped waste that still has a high economic value as a base for the oleochemical industry, one of which is β-carotene. The study was conducted to optimize the extraction of carotenoids from Crude Palm Oil (CPO) and Palm Oil Mill Effluent waste (POME) conducted by column chromatography and extraction method with a single enz...
leaching of molybdenite concentrate with hydrogen peroxide in sulfuric acid solution was investigated to determine the effects of reaction time, reaction temperature, h2o2 concentration, h2so4 concentration, pulp density and rotation speed on molybdenum extraction and molybdenite dissolution kinetics, using the taguchi method. from analysis of variance (anova) for molybdenum extraction, the mos...
abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
In recent years, the sudden increase in environmental awareness has resulted in more attention to this sector. On this basis, the economic load distribution models, that previously observed merely the minimization of the cost of production and determination of optimal arrangement of producers based on minimization of the total cost, are now facing a fundamental change in execution and modeling....
Vanillin was extracted from vanilla beans using pretreatment with cellulase to produce enzymatic hydrolysis, and response surface methodology (RSM) was applied to optimize the processing parameters of this extraction. The effects of heating time, enzyme quantity and temperature on enzymatic extraction of vanillin were evaluated. Extraction yield (mg/g) was used as the response value. The result...
This paper mainly examined the anti-osteosarcoma activity of total flavonoids extract from traditional Chinese medicine, nidus vespae. Orthogonal design was used to design the extraction process of total flavonoids. L(3(4)) orthogonal test was performed and the extracts obtained by three optimal extraction processes were used for anti-tumour activity screening in order to determine the optimal ...
optimization of inulin extraction from helianthus tuberosus using response surface methodology (rsm)
inulin is widely used in functional foods throughout the world for its health-promoting and technological properties. helianthus tuberosus is cultivated widely in the northern part of iran. helianthus tuberosus can be a valuable source of inulin. to optimize conventional extraction of inulin, various combinations of time, temperature, and solvent: solid ratio, were used. in this research, a ser...
to investigate the optimum conditions for extracting gelatin from whitecheek shark (carcharhinus dussumieri (skin, response surface methodology (rsm) has been adopted. in this research, the effect of naoh concentration (0.01-1 n), hcl concentration (0.01-1 n), and extraction time (3-8 h) on dependent variables, yield and melting point of the skin gelatin have been studied using central composit...
The paper deals with the extraction of features for statistical pattern recognition. In particular, the case of recognition with learning is considered. Bayes probability of correct classification is adopted as the extraction criterion. The problem with incomplete probabilistic information is discussed and Bayes-optimal feature extraction procedure is presented in detail. As method of solution ...
