FTIR-ATR spectra of culinary grain legumes (pulse) flours

FTIR-ATR spectra of 5 culinary grains: 

1. chickpea (Cicer arietinum n=87)
2. lentil (Lens culinaris n=93))
3. grass pea (Lathyrus sativus n=116)
4. pea (Pisum sativus n=119)
5. faba bean (Vicia faba n=93)

Grains were dried at 40 °C and milled using a miller Retsch cyclone mill with a particle size under 0.8 mm. The different flours were stored at -20 °C. For FTIR-ATR analysis there was no need for further sample preparation.
