Public health and regulatory assessments and guidance on sugars increasingly focus on free (rather than total or added) sugars in the diet. This emphasizes differentiation between sugars consumed within versus outside of an intact plant matrix. However, there is no analytical method for free sugars, and quantitative determination in heterogenous and processed products containing mixed sizes of plant particulates as ingredients (e.g., soups or chopped and cooked foods) is particularly problematic for nutrition declarations and monitoring. The method suggested here is based on sieving, with the particle size threshold derived from data on the typical end-products of mastication. This simple method could generate an objective, quantitative estimate of free sugars that logically corresponds to the free sugars concept in public health. It has the potential to be applied to many product types, and is proposed as a possible standard method for empirical testing and possible wider validation and endorsement.

一种用于客观定量食品和饮料中游离糖的简单方法。

关于糖的公共卫生和法规评估与指南越来越关注饮食中的游离糖（而不是总糖或添加糖）。这强调了完整植物基质内部和外部消耗的糖之间的区别。但是，目前尚无游离糖的分析方法，对于含有混合大小的植物颗粒作为成分的异质和加工产品（例如汤或切碎和煮熟的食品）进行定量测定对于营养声明和监测尤其成问题。此处建议的方法是基于筛分的，其中粒度阈值源自有关典型咀嚼终产物的数据。这种简单的方法可以生成客观，定量的游离糖估计，其逻辑上与公共卫生中的游离糖概念相对应。
