Identification and quantification of anthocyanin pigments in colored rice [PDF]
Nutrition Research and Practice, 2008 Anthocyanin pigments from varieties of black, red and wild rice were identified and quantified to evaluate their potential as nutritional function, natural colorants or functional food ingredients. Anthocyanin extraction was conducted with acidified methanol with 0.1M HCl (85:15, v/v) and identification of anthocyanin, aglycone and sugar moieties was ...

MALDI-TOF mass spectrometric identification of dyes and pigments [PDF]
Journal of the American Society for Mass Spectrometry, 2007 We have used MALDI-TOF mass spectrometry to characterize a selection of dyes from the Schweppe dye collection and pigments from the Tate Gallery collection. MALDI-TOF mass spectra of such samples are easily obtained and, through observation of both positive and negative ion spectra, provide a convenient, versatile method for dye characterization and ...
