Influence of germination on the bioactivity, structural, functional and volatile characteristics of different chickpea flours

Abstract

In this paper, the objective was to evaluated the impact of germination of chickpea cultivars (Muying1, Y2-514 and YZ-364) on the bioactivity, volatiles and functional properties. The results showed that the Vitamin C content of Muying1, Y2-514 and YZ-364 after germination significantly increased (p < 0.05). Moreover, the germination also caused a significant decrease in lower transition temperatures and enthalpy values in chickpea flours (p < 0.05). After germination treatment, β-sheet and random coils in protein secondary structures increased and β-turn decreased in YZ-364; α-helix, β-sheet and random coil in Y2-514 and Muying1 decreased, while β-turn increased. The germination significantly enhanced the functional properties of three chickpea flours (p < 0.05). It was proved that the germination significantly enhanced the total phenolic and flavonoids content, antioxidant activity and in vitro protein digestibility. The GC-IMS revealed that the germination could affect the contents of volatile compounds of chickpea flours.
