“…Guifang Fan et al managed to make use of NIR spectroscopy to monitor the process of the solid-state fermentation of sweet sorghum stalks rapidly and efficiently. 4 This paper discussed the feasibility of utilising NIR spectroscopy for the rapid analysis of process parameters in a new fermentation system, which converts soluble sugars in sweet sorghum stalks to ethanol. The process parameters include mass fraction of sugar, alcohol and water, and pH value.…”
