Abstract
The aim of this study was to introduce a simple, high efficient and less expensive method for isolation of βLg from whey. Anion exchange chromatography, pepsin enzyme treatment and ultrafiltration tecniques were preferred for isolation process to compare differences. In addition to, centrifuge ultrafiltration techniques were using for the first time for isolation of β-Lg from whey. Physicochemical analysis of whey samples indicated that protein and β-Lg content in whey samples changed from 0.07 to 0.8% and 0.24 to 0.29 g/L, respectively. Treatment with the use of pepsin enzyme, anion exchanges chromatography and ultrafiltration techniques, resulted to β-Lg of 1.43, 6.56 and 43.59 folds respectively. Our results showed that ultrafiltration techniques are rapid and efficient that allows high protein yield and has advantages over other methods since it preserves the native structure of β-Lg. Additionally, when the enzymatic hydrolysis was used together with ultrafiltration technique, it was found efficient and pure than the enzymatic hydrolysis together with dialyse membrane. Also this study concluded that pepsin enzyme treatment and anion exchange chromatography are economic methods but they are not efficient enough and very time consuming. However isolation efficiency can be increased the use of isolation methods together
