Manufacture of Precheese Powder by Use of Low-temperature Renneting Made from Raw Milk Using Spray Dryer

Among the food constituents, proteins differ in coagulation properties as compared to other constituents in food system. Especially milk protein coagulate through different pathways thus this coagulability can be used for manufacture of various dairy products or as a determinant of dairy product analysis. These milk coagulation methods include organic solvent, isoelectric point, trichloroacetic acid, Ca-sensitive casein, heavy metal ion and rennet coagulation. The coagulation experiment was performed using above parameters at 0oC and 25oC to find the dehydration conditions before coagulating for precheese powder making. After different chemical treatments, there was no coagulation at 0oC rather at 25oC whatever the mode of coagulation methods was. The appearance of precipitate with coagulation methods was quite different from above mentioned methods of coagulation illustrated by scanning electron microscope. These powders were used for fabrication of camembert cheese by renneting coagulation at 0oC, showing the possibility of cheese materials and of food additives for fabrication of products.
