- Packages of different atmospheres (air (control), 100% CO2, vacuum, and vacuum + O2 absorber) were prepared for 0.4 kg rice cake (ddukgukdduk) using gas-barrier plastic film and stored at 10oC for 11 days. The stored products were evaluated in their packages atmosphere, total aerobic bacteria, yeast and molds, texture and sensory quality during storage period. In the air package, the O2 concentration decreased from initial 21% to 16% on storage 4 days and the CO2 concentration increased to 23% on storage of 11 days, which resulted from the growth of microorganisms. CO2 concentration decreased from initial 98% to 36% on storage 11 days in the 100% CO2 package. It is reasoned that CO2 was dissolved into the product reducing the volume of the package. Vacuum and vacuum +O2 absorber package maintained shrunk vacuum condition until 11 days of storage. Total aerobic bacteria count increased significantly in the control package (6.41 log (cfu/g) after 11 days) compared to the 100% CO2 package (4.96 log (cfu/ g) after 11 days). Yeast and molds were 6.66 in control package, 3.43 in 100% CO2 package, 4.66 in vacuum package, and 3.78 in vacuum + O2 absorber package after 11 days. There was no significant difference between control and the other treatments for the texture of the stored products. Sensory quality was the worst in control package on the storage of 8 days. All treatment groups except control improved the quality preservation, but vacuum and vacuum + O2 absorber packages suffered from cracking of the product. Thus 100% CO2 flushing is suggested as a desired packaging condition.
