A study was conducted to investigate cryoprotectant effect of commercially produced oligosaccharides (IMO: isomalto-oligosaccharides, FO: fructo-oligosaccharides and GO: galacto-oligosaccharides) on beef protein and to compare their effectiveness to sucrose or a mixture of sucrose and sorbitol on freezing. The optimal addition level of cryoprotectants was determined by measuring $Ca^{2+}$-ATPase activity of sample treated with different concentration (0 to 12%) after freeze-thaw cycle. Since the stabilization effect was not dramatically increased above 8% sugar concentrations, the 8% was determined as an usage level. During frozen storage (at -18$^{circ}C$ for 12 week), commercially produced oligosaccharides showed lower cryoprotection ability than sucrose but higher than sucrose+sorbitol as measured by protein solubilities and $Ca^{2+}$-ATPase activities.
