“…It is evident that inulin chains with DP 2 to DP 18 are present. The results are consistent with those reported by Borromei et al (2009) Han et al (2016) and Evans, Gallagher, Ratcliffe, and Williams (2016) for other commercial inulin samples. The average DP was determined to be 8 as calculated using Eq.…”

“…In recent years particular attention has been paid to the derivatisation of inulin (Exerowa et al, 2009;Han, Ratcliffe, & Williams, 2015;Kokubun, Ratcliffe, & Williams, 2013;Morros, Levecke, & Infante, 2010;Tadros and Vincent, 1983;Tadros, 1999;Tadros, Vandamme, Booten, Levecke, & Stevens, 2004). Inulin is an abundant reserve polysaccharide found in many plants including chicory, garlic, leek, artichoke and onion but the primary industrial source is chicory with over 350,000 t produced annually (Evans, Han, Ratcliffe, & Williams, 2016). It consists of → β(2 1) linked fructose units which are terminated with a glucose residue andhas a degree of polymerisation of 2-60.…”

A B S T R A C TA series of inulin derivatives were synthesized in aqueous solution using acyl chlorides with varying alkyl chain length (C10-C16). They were characterised using a number of techniques including MALDI TOF-MS, 1 H NMR and FTIR and their degree of substitution determined. The solution properties of the hydrophobically modified inulins were investigated using dye solubilisation and surface tension and it was confirmed that the molecules aggregated in solution above a critical concentration (critical aggregation concentration, CAC). The value of the CAC was found to be reasonably consistent between the different techniques and was shown to decrease with increasing hydrophobe chain length. It was found that the C10, C12 and C14 derivatives formed stable oil-inwater emulsions and the emulsion droplet size decreased with increasing alkyl chain length. The C16 derivative was not able to produce stable oil-in-water emulsions; however, it was able to form stable water-in-oil emulsions. The fact that the derivatives are able to form micellar-like aggregates and stabilise emulsions makes them suitable candidates for the encapsulation and delivery of active compounds with potential application in food, cosmetic, personal care and pharmaceutical formulations.

“…There is strong interest in developing SBSs derived from renewable resources for potential application in industrial formulations [29]. Until now, the research has tended to focus on the derivatives of inulin, which is an abundant reserve polysaccharide found in chicory, onion, and garlic, with over 350,000 t produced annually [30]. Inulin consists of linear chains of β-2, 1-linked d-fructofuranose molecules terminated by a glucose residue through a sucrose-type linkage at the reducing end.…”

Shale hydration dispersion and swelling are primary causes of wellbore instability in oil and gas reservoir exploration. In this study, inulin, a fructo-oligosaccharide extracted from Jerusalem artichoke roots, was modified by acylation with three acyl chlorides, and the products (C10-, C12-, and C14-inulin) were investigated for their use as novel shale hydration inhibitors. The inhibition properties were evaluated through the shale cuttings hot-rolling dispersion test, the sodium-based bentonite hydration test, and capillary suction. The three acylated inulins exhibited superb hydration-inhibiting performance at low concentrations, compared to the commonly used inhibitors of KCl and poly (ester amine). An inhibition mechanism was proposed based on surface tension measurements, contact angle measurements, Fourier-transform infrared analysis, and scanning electron microscopy. The acylated inulin reduced the water surface tension significantly, thus, retarding the invasion of water into the shale formation. Then, the acylated inulin was adsorbed onto the shale surface by hydrogen bonding to form a compact, sealed, hydrophobic membrane. Furthermore, the acylated inulins are non-toxic and biodegradable, which meet the increasingly stringent environmental regulations in this field. This method might provide a new avenue for developing high-performance and ecofriendly shale hydration inhibitors.

This review is the ninth update of the original article published in 1999 on the application of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2016. Also included are papers that describe methods appropriate to analysis by MALDI, such as sample preparation techniques, even though the ionization method is not MALDI. Topics covered in the first part of the review include general aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, fragmentation and arrays. The second part of the review is devoted to applications to various structural types such as oligo‐ and poly‐saccharides, glycoproteins, glycolipids, glycosides and biopharmaceuticals. Much of this material is presented in tabular form. The third part of the review covers medical and industrial applications of the technique, studies of enzyme reactions and applications to chemical synthesis. The reported work shows increasing use of combined new techniques such as ion mobility and the enormous impact that MALDI imaging is having. MALDI, although invented over 30 years ago is still an ideal technique for carbohydrate analysis and advancements in the technique and range of applications show no sign of deminishing. © 2020 Wiley Periodicals, Inc.
