CO₂ absorption by zeolite and active carbon was investigated as a tool to alleviate the pressure buildup and volume expansion that results from carbon dioxide production in kimchi packages. Zeolite was more effective than active carbon in terms of CO₂ absorption capacity, and could also maintain CO₂ adsorption equilibrium as long as it was protected from water vapour. A plastic film with high CO₂ transmission rate and limited water vapour permeability was able to control the CO₂ absorption rate of the zeolite sachet. Zeolite sealed in 10μm thick high density polyethylene could significantly reduce pressure and volume increase when included inside kimchi packages at 15°C.
