Sinigrin has drawn more attention of pathologists and immunologists,which exhibited a wide range of biological activities including anti-bacterial,anti-fungal and anti-cancer [1].In the present study,the feasibility of concentration of sinigrin by nanofiltration was studied.Experiments were made by using one-factor-at-a-time method with permeate flux and sinigrin retention,after 7 commercial membranes were compared,including NF,NF-270,SPESI,STARMEN 120,STARMEN 128,STARMEN 220,STARMEN 240,investigating the influence of temperature,pressure and feed concentration,for the concentration of sinigrin from crude aqueous extracts of Indian mustard seeds after ultrafiltration [2].The results indicated that NF-270 membrane showed the highest permeate flux and the best retention capability to sinigrin.Its ranges of permeate flux and sinigrin retention were 7.44-23.47 L/(m2.h) and 90.77-97.13%,respectively.
