摘要

摘要: 为研究北京地区不同菠菜品种的贮藏性差异,选取具有代表性的5个品种:抗病王、农大菠杂1号、菠杂10号、先锋、日本大叶,测定其相关指标:感官评价、失重率、电导率、维生素C含量、叶绿素含量、过氧化物酶(POD)活性、多酚氧化酶(PPO)活性。记5分为商品性界限值,第11 d时,只有农大菠杂10号感官评价不低于5分,日本大叶第7 d的感官评分为5,失去商品性,日本大叶的失重率最大,为23.14%,农大菠杂1号的失重率最小,为10.78%,维生素C的含量减少最多的是日本大叶,为75.26%,减少最少的是农大菠杂1号,为52.74%。综合评价各项指标,5个不同品种菠菜耐贮藏性好坏的顺序依次为:农大菠杂1号>菠杂10号>日本大叶>抗病王>先锋。

Abstract: Five typical varieties were selected to study the storage characteristics in different varieties of spinach in the Beijing area.Spinach were King of disease-resistant, Nongda bo's miscellaneous 1, Nongda bo's miscellaneous 10, Pioneer, Japanese big leaf, and the quality change had been studied in the storage period.Indices were sensory evaluation, the weightlessness rate, conductivity, vitamin C content, chlorophyll content, activity of peroxidase, polyphenol oxidase activity. Regard 5 score as the commercial limit, on the 11 th day, only Nongda bo's miscellaneous' s sensory evaluation was not less than five points, Japanese big leaf's sensory score was 5 on the 7th day and lost the commercial, Japanese big leaf's weightlessness rate was maximum, reached up to 23.14%, and the Nongda bo's miscellaneous 1 's weightlessness rate was minimum, at 10.78%. The vitamin C content of Japanese big leaf reduced mostly, and was 75.26%.The vitamin C content of Nongda bo's miscellaneous 1 reduced least, as much as 52.74%. Comprehensive evaluation of various indicators, five different varieties of spinach were resistant to storage quality in the order of: Nongda bo's miscellaneous 1 > Nongda bo's miscellaneous 10 > Japanese big leaf > King of disease-resistant > Pioneer.
