Abstract
The objective of this study was to investigate the effect of starch debranching followed by differential ethanol precipitation on the formation and in vitro fermentation of starch-lipid complexes. Three groups of linear glucan chains, with a degree of polymerization (DP) of 383∼2950, 37∼75, and 3∼8, were obtained after debranched maize starch (DMS) was fractionated by differential ethanol precipitation. The glucan fraction with DP 383∼2950 formed only type IIb complexes with lauric acid (LA), whereas the fraction with DP 37∼75 formed predominantly type Ia complexes. The glucan faction with DP 8∼32 did not form V-complexes with LA. In vitro fermentation of the type IIb complexes with human fecal samples promoted the proliferation of butyrate-producing bacteria Megamonas, Blautia, and Megasphaera and resulted in a larger amount of butyrate and total short-chain fatty acids being produced than in similar fermentations of the maize starch-LA complex, DMS-LA complex, and fructo-oligosaccharides. This study showed that starch-lipid complexes with a more stable type IIb crystallite resulted in a greater production of butyrate.

JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY 2021; 32:1498-1507. [PMID: 33988368 PMCID: PMC8176450 DOI: 10.1021/jasms.1c00071] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/28/2021] [Accepted: 05/04/2021] [Indexed: 06/12/2023]
Abstract
Trapped ion-mobility spectrometry combined with quadrupole time-of-flight mass spectrometry (TIMS-QTOFMS) was evaluated as a tool for resolving linear and branched isomeric polyester oligomers. Solutions of polyester samples were infused directly into the ion source employing electrospray ionization (ESI). TIMS-MS provides both mobility and m/z data on the formed ions, allowing construction of extracted-ion mobilograms (EIMs). EIMs of polyester molecules showed multimodal patterns, indicating conformational differences among isomers. Subsequent TIMS-MS/MS experiments indicated mobility differences to be caused by (degree of) branching. These assignments were supported by liquid chromatography-TIMS-MS/MS analysis, confirming that direct TIMS-MS provided fast (500 ms/scan) distinction between linear and branched small oligomers. Observing larger oligomers (up to 3000 Da) using TIMS required additional molecular charging to ensure ion entrapment within the mobility window. Molecular supercharging was achieved using m-nitrobenzyl alcohol (NBA). The additional charges on the oligomer structures enhanced mobility separation of isomeric species but also added to the complexity of the obtained fragmentation mass spectra. This complexity could be partly reduced by post-TIMS analyte-decharging applying collision-induced dissociation (CID) prior to Q1 with subsequent isolation of the singly charged ions for further fragmentation. The as-obtained EIM profiles were still quite complex as larger molecules possess more possible structural isomers. Nevertheless, distinguishing between linear and symmetrically branched oligomers was possible based on measured differences in collisional cross sections (CCSs). The established TIMS-QTOFMS approach reliably allows branching information on isomeric polyester molecules up to 3000 Da to be obtained in less than 1 min analysis time.
