摘　　要：研究常温条件下CO_(2)处理对120份柿果实单宁含量、硬度、可溶性固形物的影响,探究CO_(2)脱涩后柿果实品质的变化。结果表明,CO_(2)处理可显著降低柿果实中的单宁含量,根据脱涩与否可将120份种质资源分为2大类(未脱涩种质和脱涩种质)。未脱涩种质47份(39.16%),脱涩种质73份(60.84%)。未脱涩种质可分为2类:返涩种质(‘朱罐罐’‘都江堰干柿’等)占总资源的3.33%和无法脱涩种质(‘临潼挂干柿’‘从化柿’等)占总资源的35.83%,其中返涩现象是CO_(2)脱涩处理中首次被发现。脱涩种质可分为2类:易脱涩种质(‘荥阳水柿’‘蜜蜜罐’等)和难脱涩种质(‘小广扁柿’‘什样柿’等),其中易脱涩种质35份,难脱涩种质38份,分别占总脱涩种质的47.93%和52.07%。以上结果表明大部分柿种可以通过CO_(2)处理完成脱涩。通过单宁含量、硬度变化以及可溶固形物含量变化分析,发现18个种质包括‘上虞方柿’‘兰田南王水花柿’‘么心柿’‘西畴水柿’‘柏东-01’‘松阳扁柿’‘垣曲八月红’‘杭州牛心柿’‘小红柿’‘永济木柿’‘王后柿’‘沙谷1号’‘堂上蜂屋’‘秋蒸饼’‘乾县木娃柿’‘小合柿’‘照天红’‘临潼鸡心黄’在脱涩过程中硬度以及可溶性固形物含量下降不显著,并且能够很好地保持柿果实的商品性,有利于后续的贮藏销售。Under normal temperature condition,the effect of CO_(2)treatment on tannin content,hardness and soluble solids of 120 persimmon fruits were studied,and the quality changes of persimmon fruits after CO_(2)de-astringency were investigated.The results showed that CO_(2)treatment could significantly reduce the tannin content in persimmon fruits.According to the astringency degree,120 germplasm resources could be divided into two categories(non astringent germplasm and de-astringent germplasm).47 of the non astringent germplasm accounted for 39.16%of the total resources;73 de-astringent germplasm accounted for 60.84%of the total.The non astringency germplasm could be divided into two types:the re-astringent germplasm(‘Zhuguancan’‘Dujiangyan Ganshi’,etc.),accounting for 3.33%of the total resources,and the incapable de-astringency germplasm(‘Lintong Guaganshi’‘Conghua Shi’etc.).accounting for 35.83%of the total resources.The re-astringent germplasm was first discovered in the process of CO_(2)de-astringency.The de-astringent germplasm could be divided into two types:easy de-astringent germplasm(‘Xingyang Shuishi’‘Mimiguan’,etc.)and hard de-astringent germplasm(‘Xiaoguangbianshi’‘Shiyangshi’),among which 35 germplasms were easy de-astringent,38 germplasms were hard de-astringent,accounting for 47.93%and 52.07%of the total de-astringent,respectively.The results showed that most of persimmon germplasm resources could be completely de-astringent under CO_(2)treatment.Through the analysis of tannin content,hardness change and soluble solid content change,we found that 18 varieties,including‘Shangyu Fangshi’‘Lantiannanwang Shuihuashi’‘Mexinshi’‘Xichou Shuishi’‘Bai Dong 01’‘Songyang Bianshi’‘Yuanqu Bayuehong’‘Hangzhou Niuxinshi’‘Xiaohongshi’‘Yongji Mushi’‘Wanghoushi’‘Shagu 1 Hao’‘Tangshangfengwu’‘Qiuzhengbing’‘Qianxian Muwashi’‘Xiaoheshi’‘Zhaotianhong’‘Lintong Jixinhuang’,had no significant changes in the hardness and solubl
