In contrast, where the extracted temperatures have been disappointing, exploration efforts have been reduced resulting in a lack of further data.
Three SFE-CO2 parameters namely extracting pressure, extracting temperature, and flow rate of carbon dioxide were examined.
As results, the optimum conditions were extracting temperature 80 °C, extracting time 4.5 h and the ratio of extraction solvent (water) to raw material (v/w) 8.
The optimal SFE-CO2 conditions for the extraction tocopherol-enriched oil from Kalahari melon seeds were: extracting pressure 290 bar, extracting temperature 58 °C, and flow rate of carbon dioxide 20 ml/min.
The optimal extraction conditions for the Se-enriched H. erinaceum polysaccharides were: extracting time 115 min, extracting temperature 98 °C, ratio of liquid to solid 4, and extracting number 4. Compared with untreated cells, administration of Se-enriched H. erinaceum polysaccharides improved BMC and BMD in experimental rats.
The methods of 'histograms and cumulants' have been applied to extract temperature dependent information from dynamic simulations of polyethylene.
The main parameters affecting the formation of nanoparticles, including pH of extract, temperature of synthesis process and extract concentration were investigated and optimized.
The optimum conditions for roselle seeds were extracting pressure 200 bar, extracting temperature 80 °C, and flow rate of carbon dioxide 20 ml/min.
The optimum conditions were predicted as follows, ratio of water to raw material at 30, extracting temperature at 85 °C, extracting duration at 3 h, and yield was estimated at 4.55%.
Further optimization of enzyme production was carried out using Box Behnken design of experiment to study the influence of process variables (beef extract, temperature and tween 80) on cellulase and xylanase production.
