Ceramic far-infrared (cFIR) emitting materials are sources of room temperature FIR radiation that allow non-thermal irradiation of biological tissue. In this study, we explored some interesting physical and chemical effects that have not been reported. We investigated the effects of cFIR irradiation of sorghum wine using gas chromatography with solid-phase micro-extraction (GC-SPME) to demonstrate enhancement on volatility; monitored pH changes resulting from irradiation on acetic acid; and used UV spectroscopy to identify and quantify chemical changes. On the basis of the results, we deduced that cFIR possesses the ability of weakening hydrogen bond and exhibits chemical reduction change. The methods above provide a relatively convenient and cost-effective test platform to demonstrate the application of cFIR as an effective alternative to biological assay.
