通过测定枣果内含物含量,初步探究枣裂果发生的机制,为生产上防止枣裂果提供理论依据。以南方鲜食枣中秋酥脆枣为试材,采用蒽酮比色法、考马斯亮蓝法等方法,对枣果中可溶性糖、淀粉、可溶性蛋白质等内含物含量进行测定。结果表明:从白熟期至完熟期,枣果中可溶性总糖、淀粉、维C及Ca、K含量均呈逐步上升趋势,还原糖、可溶性蛋白质及Mn、Na含量均呈逐步下降趋势;各个时期正常果中淀粉和可溶性蛋白质含量均比裂果高,完熟期正常果淀粉含量为7.43%,比裂果淀粉含量6.29%高1.14%,差异性显著;正常果中Ca、Na含量均比裂果高,完熟期正常果Ca含量为58.06 mg/100g,显著高于裂果的48.88 mg/100g,而K、 Mg、Fe...

This study aimed at studying preliminarily the mechanism of jujube fruit cracking by determing the content of inclusions of normal and cracking jujube fruit in different periods to prevent the jujube fruit cracking in production and provide a theoretical basis. Taking the south of fresh jujube - zhongqiusucui Zao as test material, reducing sugar content was determined by 3,5-Dinitrosalicylic acid method; vitamin C content was determined by 2.6-dichlorophenolindophenol method of sodium;Soluble protein was determined by Coomassie brilliant blue method;Mineral content was determined by ICE3500 de...
