Question

can you please explain the procedure of the investigatory project on the study of coagulable and non coagulable milk proteins???

Answer 1

 AIMTo study the coaguable and non-coaguable milk proteinsINTRODUCTIONMilk is considered an idea ood as it contains most o the constituents o our diet! It is arichsource o proteins and ats!
