Abstract:
The study of the recovery of soybean isoflavone and oligosaccharides from soybean whey wastewater by adsorption and desorption of resin and active carbon was conducted .The adsorption saturation curve of isoflavone on resin columnand oligosaccharide on active carbon column was determined , and the condition of desorption by use of 5 %-60 %ethanol concentration was also investigated .The results showed that 130 g isoflavone with the content of 40 % and 9 kgoligosaccharide were obtained from 1 ton of soybean whey wastewater , and the COD and BOD decreased from 13600 and7800 to 960 and 340 respectively .The process can achieve great economic benefit .
