Perfil químico de cultivares de feijão (Phaseolus vulgaris) pela técnica de high resolution magic angle spinning (HR-MAS)

Abstract

The application of one-dimensional proton high-resolution magic angle spinning (1H HR-MAS) NMR combined with a typical advantages of solid and liquid-state NMR techniques was used as input variables for the multivariate statistical analysis. In this paper, different cultivars of beans (Phaseolus vulgaris) developed and in development by Embrapa – Arroz e Feijão were analyzed by 1H HR-MAS, which have been demonstrated to be a valuable tool in its differentiation according chemical composition and avoid the manipulation of the samples as used in other techniques.
