In this experiment, alcohol and blanching treatments were used for food packaging materials, quality of powder yam and sliced yams (5 mm size) were compared by alcohol concentration and time for measuring change of color, weight, moisture content saccharinity and decomposition. 5% and 10% alcohol were used to alcohol treatment for 5, 10 seconds each. Packaging materials were used OPP(30 μm), PET(25 μm), ON(25 μm) and all materials heat sealable were coated. Quality of powder yam were not changed during storage at low temperature however were changed during storage at room temperature after 5 days. In conclusion, powder yam were needed packaging materials with high water barrier property from moisture, sliced yams were high quality when packaged by ON and stored at low temperature. Therefore, using packaging materials with low oxygen permeability were expected to reduced quality degradation about browning of powder yam and sliced yams.

One-way degassing valves usually designed for coffee packaging are recently applied to the various food packaging such as fermented health functional food or home meal replacement (HMR) packaging. The optimized degassing pressure by food product is important factor for keeping effective freshness and improving preservation of the food, therefore the development of degassing valves specified with various open pressure is needed. In this study, the mechanical characteristics of the degassing valve with ring type rubber disk were analyzed and a mathematical model was developed to predict the open pressure of the valve. The model was verified with test results derived from several available valves, and it may be useful in designing and developing a new valve.
