Hi Pals, Today we will see the procedure To separate casein healthy protein from milk For this we have determined 100 ml of milk in a beaker As well as heated up at concerning 50 degree celsius After heating Remove the drifting lotion from the milk surface With the aid of spatula After eliminating cream In following step Start adding 10%Acetic acid solution But it ought to be decline smart Never ever transfer the acetic acid at the same time. Drop by Drop adding is a great practice for this Additionally mix the remedy with the aid of glass rod So that acetic acid will certainly mix well with milk As you can see casein has not yet precipitate So we will again acetic acid drop smart in milk And also once again mix well with glass rod In this procedure remember something that when we include acetic acid in milk example Then the temperature of milk should be around 50 degree Celcius To ensure that casein protein may speed up appropriately Currently once again blend with glass rod You can see, currently casein has sped up completely Now maintain this remedy as such over the table To make sure that liquid and precipitate may get separated Now separate the precipitate from liquid The concept of this process is that At the normal pH of milk Casein exists in soluble type And also when we include acetic acid Ph of milk began to drop And when pH reaches to 4.6 Casein began to obtain precipitated Because the separated pH od casein is 4.6 As well as at this pH casein is insoluble in milk And this hot precipitated Now the collected casein protein in filter paper Is included 50% combination of diethyl ether as well as ethanol at the ratio of 1:1 Once more mix well with the help of glass pole So additional fat may come down to our solvent system After blending again filter it After compleat filtering Discard the filtrate And also gather the casein healthy protein Maintain filtring till service obtain removed from casein As you are seeing, solvent is still in the casein So continue till it leaves casein Currently all solvent has been removed from casein Transfer the casein protein in Petri plate And leave it for drying out Ultimately casein healthy protein has actually been dried This is just how it appears like You can likewise weigh it if required.Thank You.
