Microstructure of Fat Free Plain Set-type Yogurt Containing Folic Acid

The objective of this study was to investigate the microstructure of folic acid-contained yogurt. Folic acids (25 and 50%) were added to milk preparation prior to pasteurization, then starter culture was added. The microstructure of yogurt containing folic acid was determined by the size of cluster of casein micelle using scanning electron microscopy and transmission electron microscopy. The cluster of casein micelle in yogurt containing folic acid were showed larger size than in control (p
