摘要
通过三种不同透性的包装材料对鲜切马铃薯进行包装处理,探讨了其对鲜切马铃薯丝贮藏品质的影响。清洗切分后的马铃薯丝于4℃冰箱中贮藏,对其色差(L*,△E*值)、褐变度(BD)、气体含量、呼吸速率、丙二醛(MDA)含量及整体感观质量(OVQ)进行检测与评定。研究表明:透气性好的PE2包装较其他两种包装材料更有利于保持鲜切马铃薯的感官品质,延缓组织内MDA的积累;O2和CO2含量易于达到动态平衡,能够有效抑制褐变及呼吸速率的加剧,从而延缓了组织衰老的进程,改善其贮藏品质。
The efficacy of three different packaging materials in improving the storage quality on fresh-cut potato was investigated. Cleaned and sliced potatoes were stored at 4℃ for 7d. The color difference（L＊,△E＊ value）, browning degree （BD）, gas components, respiratory rate, content of malondialdehyde （MDA） and the overall visual quality（OVQ） were detected every day. The results showed that PE2 packaging with high gas permeability could retain deterioration of color quality, slow down the accumulation of malondialdehyde （MDA）, and O_2 and CO_2 was easy to achieve dynamic balance,inhibit browning and respiratory rate,so as to slow down senescing, improving the storage quality.
