Production of sialic acid-containing hydrolysatefrom hen egg yolk powder
This paper expounded about the method of preparing sialic acid-containing condensed hydrolysate of hen egg yolk powder(prepared for coming ion-exchange chromatograph).Including the method of delipid of egg yolk powder,optimization of factors which affect the result of hydrolysis,ultrafiltration and nanofiltration of hydrolysate.Sialic acid was detected at a level of 1200μg/mL in the final condensed hydrolysate,which is equivalent to 1.67mg sialic acid in 1g dryed delipidated egg yolk.
