Packaging Bags with the Function of Micro-environment Modification
|
摘要
Three kinds of packaging bags composited with barrier film and moisture absorbents were designed in order to find out how to create an internal micro-environment with low O2content and relative humidity( RH). Peanuts with different moisture contents were filled into packaging bags and stored in an environmental chamber for a certain period of time. An RH recorder was sealed in each bag and the RH inside the bag was recorded. The moisture contents of peanuts before and after storage were measured as well.It is found that peanuts with moisture content of 13% can reduce O2content inside the bag by the aerobic respiration,achieving the self modified atmosphere packaging( MAP) effect. A microenvironment with lower RH can be created by using super-absorbent fiber( SAF) or mineral bag as the moisture absorbent. The moisture contents of peanuts stored in the bags with SAF and mineral bag as moisture absorbent decreased from 13% to 10. 5%and 11. 3%,respectively. SAF is a promising material of packaging bags composited with barrier film,in which a low RH and high CO2content can be created.
