Experimental water adsorption isotherms and Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) analysis in Achira (Canna edulis K.) biscuits

The dataset compiles water adsorption isotherms and infrared spectral data for Achira (Canna edulis K.) biscuits. The water sorption isotherms were experimentally determined using the Dynamic Dewpoint Isotherm (DDI) method, with measurements taken over a water activity range from 0.1 to 0.8, at temperatures of 25, 35, and 45 ºC. The Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy technique was employed to characterize the spectral properties of the biscuits. This dataset provides a comprehensive basis for researchers, food scientists, and industry professionals to model key parameters related to the shelf life and hygroscopic behavior of Achira biscuits. Additionally, the data supports the development of optimized packaging solutions designed to maintain moisture stability and preserve sensory qualities. The dataset is organized in Excel sheets and structured by experimental conditions and replicates.
