不同枣品种果实中可溶性糖及组成成分分析
|
摘要
为深入开发枣资源,以永城长红、保德油枣、滕州躺枣、上海白浦、中宁小圆枣、晋矮1号、中阳木枣、襄汾木枣、北碚小枣、宣城圆枣、薄皮枣、义乌大枣12个枣品种为试验材料,采用高效液相色谱方法对果实糖含量及其组成成分进行测定。结果表明:不同枣品种果实中可溶性糖、葡萄糖、果糖和蔗糖含量不同及其比例不同,供试12个枣品种果实中可溶性糖变化范围在55.53%～85.66%,葡萄糖含量变化范围在10.19%～30.19%,果糖含量变化范围在12.95%～27.12%,蔗糖含量变化范围在15.73%～66.87%;葡萄糖和可溶性总糖的比例在1∶2.40～1∶8.86,还原糖和可溶性总糖比例在1∶1.28～1∶3.92,蔗糖和可溶性总糖比例在1∶1.34～1∶4.59。北碚小枣、上海白浦、保德油枣、宣城圆枣是还原糖累积型,晋矮1号和中阳木枣是中间类型,滕州躺枣、永城长红、薄皮枣、中宁小圆枣、襄汾木枣、义乌大枣是蔗糖积累型。
In order to further develop jujube resources,we studied the sugar content and the composition ratio of12 jujube cultivar by using HPLC method.The results showed that the sugar content of jujube,the contents and proportions of soluble sugar,glucose,fructose and sucrose in fruits of different jujube varieties were different,the range of soluble sugar was 55.53%-85.66%,glucose was 10.19%-30.19%,fructose was 12.95%-27.12% and sucrose was 15.73%-66.87%.The ratio of reducing sugar to total soluble sugar was between1∶1.28 and 1∶3.92,and the ratio of sucrose to total soluble sugar is between 1∶1.34 and 1∶4.59.Beipeixiaozao,Shanghaibaipu,Baodeyouzao and Xuanchengyuanzao were reducing sugar accumulation type.Jinai 1 and Zhongyangmuzao were intermediate type,Tengzhoutangzao,Yongchengchanghong,Bopizao,Zhongningxiaoyuanzao,Xiangfenmuzao Yiwudazao were sucrose accumulation type.
