Abstract
Abstract This study was designed to compare the physicochemical and nutritional properties between reconstituted milk samplesmade from freeze-dried milk powder (FDMP) and spray-dried milk powder (SDMP). Reconstituted milk (87%, wb) wasmade by combining FDMP or SDMP with water. In the color analysis, the L*, a* and b* values of the reconstituted milksamples made from both powders were not significantly differen t from the control. The thiobarb ituric acid values and short-chain free fatty acid concentrations were considerably greater in the reconstituted milk made from SDMP than in the milkmade from FDMP. The quantities of water-soluble and fat-soluble vitamins in the reconstituted milk samples made fromSDMP were significantly lower than those made from FDMP. Base d on the findings obtained in the present study, the recon-stituted milk made from FDMP appeared to be more resistant to lipid oxidation and exhibited little changes in the nutrientslevels when compared with reconstituted milk made from SDMP.
