| abstract |
The present invention provides a method for the production of whey proteins in a single step process using combination of chromatography and membrane filtration technique, comprising treating cotton cloth with a mixture of chlorosulphonic acid and chloroform and then subsequently treating it with chloroform, dilute NaOH, glycine and water to recover modified cotton cloth as the product, thereafter fixing product in a membrane filtration device equipped with modified flow pattern and then equilibrating it with equilibration buffer, followed by loading of whey for adsorption of protein on the product and washing of the product with equilibration buffer, thereafter elution of adsorbed proteins with elution buffer, and then regeneration of the product by treating it with dilute HCl and water to reuse the product. |
