extraction ratio
2.The average Mass Extraction Ratio of the measured resources in Area A is expected to be at 31.7% for assumed permissible parameter and design layouts.
3.The results showed that the optimum extraction conditions were: ratio of material to solvent 1:25, rotational velocity of agitator 250r/min, extraction temperature 80℃, extraction time 30min.
4.Tartary buckwheat protein isolate was obtained by alkaline extraction and acid precipitation. The extraction process was optimized by single factor and orthogonal experiments,and the results showed that the optimal extraction conditions were pH 9.0,extraction time 30 min,ratio between material and water 1∶10 and temperature 35℃.
5.Methods of extraction from Arbutus were studied. Effects from extraction temperature, time, feedstock ratio and solvent on extraction result were studied and optimal conditions were determined. Natural arbutus pigment can be completely extracted by 40% ethanol for duration 40 minutes at a ratio arbutus mass to liquor 1∶5,a pH value of 3 and 50℃,exaction yield of the pigment 90.53%.
6.The extraction of total flavones from grosvenor momordica with ultrasonic was studied. The ethanol concentration,extraction time and material-solution ratio were investigated.
7.When extraction solvent acetic acid to alcohol ratio was 1:5,solid to liquid ratio was 1:15,40℃ ,36hours,the bacteriostasis of chilli extraction was best.
9.The isoelectric point of oat bran protein was discovered to be pI=4.4. Using alkaline solution for protein extraction from oat bran, a serial orthogonal experiments was designed and the optimal conditions with protein extraction were discovered as following: the ratio between oat bran raw material and extraction solution was 1∶10(w/v), extracting 3 hours at temperature 60℃ under pH11, and the extraction rate of protein was 58.88% under the optimal conditions.
10.Keeping the total concentration of substractes constant, synergistic extraction is found at l:10 acetate to bromide ratio.
