| 摘 要： | 比较了０．００５ｍｍ、０．００７ｍｍ、０．０２５ｍｍ聚乙烯（ＰＥ）膜，ＴＹ－１保鲜袋和ＣＦ－８硅窗保鲜袋包装对花椰菜冷藏期间品质的影响。经４５ｄ贮藏后结果表明：以上各处理的失重率分别为７．３６％（Ｐ＜０．０１）、５．８９％（Ｐ＜０．０１）、４．０８％（Ｐ＜０．０１）、２．３７％（Ｐ＜０．０１）、１．２８％（Ｐ＜０．０１），而对照为３１．８４％；抗坏血酸含量（ｍｇ／１００ｇ）处理组分别为１０．９４（Ｐ＞０．０５）、５２．０７（Ｐ＜０．０１）、４５．８９（Ｐ＜０．０１）、４２．２３（Ｐ＜０．０１）和４４．１３（Ｐ＜０．０１），而对照为７．９３４ｍｇ／１００ｇ。试验组固形物（ＴＳＳ）含量均比对照组降低了２７％～４４％。３种包膜处理的有机酸含量则比对照高出３９％～５８％，各处理间以０．０７ｍｍＰＥ单花头包膜效果最好。

| Abstract: | A comparison was made on the quality of cauliflower orerwrapped with PE film in 0 005 mm, 0 007 mm and 0 025 mm thickness respectively, packaged with PE bag (TY 1) and si locon window PE bag (CF 8) during cold storage after 45 days at 0℃, weight cross of packaged samples are 7 36 % ( P< 0 01) respectively, however that of nonpackaged control io 31 84 %. Ascorbic auidcontent of packaged are 10 94 mg/100 g ( P> 0 05), 52 07 mg/100 g ( P< 0 01), 45 89 mg/100 g ( P< 0 01), 43 23 mg/100 g ( P< 0 01), and 44 13 mg/100 g ( P< 0 01) respectively. However the non packaged is 7 934 mg/100 g. Total soluble soils (TSS) of packed caulifcowers were 27 %～44 % lower compared to that of control, however organic acid content of the qrerwrapped ones wore 39 %～58 % higher. Cauliflo was overwrapped with 0 007 mm thickness PE film had the best quality among the treatments. |
