Fig. S1 Stacked tacked pure component powder FT-MIR FT MIR ATR spectra for fructose, glucose, sucrose, 11 kestose and nystose. Spectra were collected from 4000 to 550 cm−1. The ATR diamond exhibits broad bands in the 2700–1800 2700 cm-1 regions due to carbon bond absorption while hydrogen and nitrogen content is responsible for bands at 3100 cm-1 and 1500–1000 1500 cm-1, respectively [1] [1] Li-Chan Chan E, Chalmers JM, Griffiths P (2010) Applications of vibrational spectroscopy in food science: Volumes I and II: Analysis of food, drink and related materials.
