Separation of proteins from ginkgo seed and their functionality
Albumin(GAP),globulins(GGP) and salt-soluble protein(GSP) were isolated from ginkgo seeds by salting-in and salting-out methods and the isolation and preparation conditions were studied.The best condition of diping ginkgo protein was that NaCl concentration was 0.14 mol/L,pH was 8.0,temperature was at 4 ℃,time was 4 h;degree was more than 3 times.There were mainly albumin and globulins in ginkgo seeds.Emulsification,stability and viscosity of GAP and GGP were studied.The result showed that the ability of emulsification,stability and viscosity of GAP were superior than GGP
