摘要
为研究贮藏温度对菠菜货架期的影响,首先从减少贮藏过程的失重率的角度对菠菜采用薄膜包装,然后研究菠菜在(0±0.5),(5±1),(10±1),(20±1)℃下贮藏期间的品质变化。结果表明,(0±0.5)℃下贮藏的菠菜具有较好的保鲜效果,(0±0.5)℃结合薄膜包装可以有效抑制失重率增加、叶绿素的分解、感官品质的下降和亚硝酸盐含量的增加,减少营养成分的损失,延长菠菜的货架寿命。
The quality changes of film packaged spinach stored at(0±0.5),(5±1),(10±1),(20±1)℃ were studied during storage.The results showed that spinach stored at(0±0.5)℃ had good preservation quality,which binding of film packaging could effectively inhibit the increase in weight loss rate,the decomposition of chlorophyll,the decline of sensory quality, and the increase in nitrite content,therefore,it would prolong the shelf life of spinach.
