| 摘 要： | 研究了微波处理与热处理对于牛奶包装材料机械性能的影响。结果表明,微波处理和热处理均会影响牛奶包装的热封强度和拉伸强度。随着微波功率和处理时间的增加,三种被测材料的热封强度和拉伸强度均呈下降趋势,尤其是C的拉伸强度变化幅度最大;随着加热温度的增加,三者热封强度升高,除B膜外,拉伸强度同样呈现上升趋势;而随着加热时间的增加,A、B热封强度相对比较稳定,但是C的热封强度呈明显上升趋势,对于拉伸强度而言,除B平均值略高于初始值以外,A与C的拉伸强度均呈明显的随时间增加而上升的趋势。特别是高温、大功率、长时间处理对包装材料的影响尤为显著。

| Abstract: | To investigate the influence of heating modes on the food package safety,the present work was designed to compare changes on the mechanical properties of packaging materials of milk submitted to microwave treatment and heating. The result showed that microwave and heat treatment could both influence the mechanical properties of the films. With the increase in microwave power and treatment time,the heat-sealing intensity and tensile strength of three tested materials were downtrend,especially for the tensile... |
