Abstract

Since high fructose intake was found to be associated with increased health risks, it is important to raise awareness towards the amount of this widely used sugar within foods and beverages. The rapid and accurate detection and quantification of sugar types is not an easy task using conventional laboratory technologies. Near-infrared (NIR) spectroscopy has been proven to be a useful tool in this regard, and the present study highlights the applicability of this rapid correlative analytical technology in the measurement of fructose concentration against that of other sugars in aqueous solutions of sweeteners. The presented NIR calibrations are accurate for the relative measure of °Brix (R2 = 0.84), and the direct measurement of the individual sugars (R2 > 0.90) even in solutions with multiple sugars.

近红外光谱法:快速有效的测定果糖含量的工具

由于发现高果糖摄入与健康风险增加有关，因此提高人们对食品和饮料中这种广泛使用的糖的含量的认识是很重要的。使用传统的实验室技术，快速准确地检测和定量糖的类型并不是一件容易的事情。近红外(NIR)光谱已被证明是这方面的有用工具，本研究强调了这种快速相关分析技术在甜味剂水溶液中果糖浓度与其他糖浓度测量中的适用性。所提出的近红外校准对于相对测量°Brix (R2 = 0.84)和直接测量单个糖(R2 > 0.90)是准确的，即使在含有多种糖的溶液中也是如此。
