Loss of crystalline and molecular order during starch gelatinisation: origin of the enthalpic transition

TL;DR: In this paper, the disruption of molecular oders which occur during the gelatinisation of starch granules has been studied by isolating dried samples from maize, waxy maize, wheat, potatoe, and tapioca starches after defined thermal pre-treatments.
Journal ArticleDOI

A novel approach for calculating starch crystallinity and its correlation with double helix content: a combined XRD and NMR study

TL;DR: The crystallinity values obtained from the XRD patterns of a wide range of native starches using this fitting technique are very similar to the double helix contents as measured by 13C solid state NMR, suggesting that double helices in granular starches are present within irregular crystals.
Journal ArticleDOI

Heterogeneity in the chemistry, structure and function of plant cell walls

TL;DR: The origins of cell wall heterogeneity are considered and contributing factors that are inherent in the molecular mechanisms of polysaccharide biosynthesis are identified and are crucial for the changing biological functions of the wall during growth and development are identified.
Journal ArticleDOI

Infrared spectroscopy as a tool to characterise starch ordered structure--a joint FTIR-ATR, NMR, XRD and DSC study.

TL;DR: It is demonstrated that FTIR is a tool that can quantitatively probe short range interactions in starch structure, however, the assumptions of linear relationships between starch ordered structure and peak ratios are overly simplistic.
Journal ArticleDOI

Crystallisation of malto-oligosaccharides as models of the crystalline forms of starch: minimum chain-length requirement for the formation of double helices

TL;DR: In this paper, the multigram preparation of malto-oligosaccharides of average d.p. ∼11, by the debranching of glycogen using Cytophaga isoamylase is described.
