甘蔗和蔗渣的蔗糖分、锤度及纤维分测定湿式分解法GB/T35998-2018

甘蔗和蔗渣是一种含有丰富蔗糖的农产品，其蔗糖含量的测定对于生产加工具有重要意义。湿式分解法是一种常见的蔗糖分测定方法，而GB/T35998-2018则是我国针对甘蔗和蔗渣的蔗糖分、锤度及纤维分测定湿式分解法制定的一项标准。

该标准主要规定了甘蔗和蔗渣的蔗糖分、锤度及纤维分测定的湿式分解法，具体内容包括标本制备、试液配制、试液pH值的调节、测定操作步骤、结果计算等方面。该标准同时也规定了适用范围和试验条件。

在实际应用中，甘蔗和蔗渣的蔗糖分测定通常采用经典的Fehling法或DNS法，但这些方法都有其优缺点。相比于这些传统的方法，湿式分解法具有操作简便、快速、准确等优点，特别适用于一些对样品数量和时间要求较高的情况。

除了蔗糖分的测定，锤度和纤维分也是评价甘蔗和蔗渣质量的重要指标。锤度直接影响到糖厂的生产效率和糖品质量，而纤维分则能反映出甘蔗和蔗渣的繁殖力、硬度和杂质含量等参数。

总之，GB/T35998-2018标准的发布，为甘蔗和蔗渣蔗糖分、锤度及纤维分的测定提供了统一的标准，不仅有利于加工生产的质量控制，也能够促进行业的健康发展。
