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.
期刊介绍：

Food and feed toxicology;
Relation between the agro technology and the food chain safety;
Microbiological food and feed analysis (pathogens, spoilage bacteria, general food/feed microbiology, microorganisms of several processing technologies etc.);
Rapid food and feed test methods (“classical” and instrumental technologies);
Molecular biological food and feed analysis (GMOs, GMO analysis etc.)
Effects of genetically modified organisms on the entire food chain and the environment;
Sensorial food and feed analysis;
Investigation of non-food products (mainly several disinfectants, production aids);
Investigation of food contact materials (migration tests, residual investigations, etc.);
Legislation topics, regulation of the whole food chain on the territory of food and feed processing, retailing, distribution (European, Hungarian, other countries);
Standardisation news and comments on the topics of whole food chain;
Other topics, results of investigations etc. (the Editorial Board keeps the right to measure the manuscripts arriving to the Editorial Office according to the principles of the journal).
