FTIR-ATR spectra of culinary grain legumes (pulse) flours
收藏资源简介：
FTIR-ATR spectra of 5 culinary grains: <br> 1. chickpea (Cicer arietinum n=87)<br> 2. lentil (Lens culinaris n=93))<br> 3. grass pea (Lathyrus sativus n=116)<br> 4. pea (Pisum sativus n=119)<br> 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.
