Fig. 2. FT-IR spectra of chickpea starch samples. (a) The FT-IR spectra of NS, RSI, RSII and RSIII in the 400–2000 cm−1 region. (b) The FT-IR spectra of NS, RSI, RSII and RSIII after baseline correcting by drawing a tangent line in the 800–1300 cm−1region. (c)The FT-IR spectra of NS of different sample dosages in KBr disc (mg/150 mg KBr) after baseline correcting by drawing a tangent line in the 800–1300 cm−1 region.
