Abstract

Sorghum Distillery Residue Activated Carbons Paperboard (SDRACP), as the value-added materials of food industrial moisture adsorbing material, was developed from fermentation residue, namely distillery grains. The SDRAC was prepared from SDR and then made with the fiber material of wood pulp into the different proportions of SDRACP. The water activity (Aw) and hygroscopic ability of SDRACP were investigated. The percent weight with various Aw foods (AwF) with SDRACP at the relative humidity (RH) of 90 and 40% and temperature of 25° was evaluated. SDRACPs of Aw were 0.46-0.51, lower than the habitat for general microorganisms (0.60). The SDRACP for placing in high/middle/low AwF at 90% showed that the middle AwF were better than the others. For the SDRACP at low RH, the stability of the high AwF was better than that of the others. Moreover, the SDRACP with 40% of SDRACs added had a higher stability for the high/middle/low AwF than that for the other SDRACPs. The developed SDRACP can therefore be an optional food moisture adsorbing material for different Aw food systems in the food industry.
