“…In addition, a series of common spectra at about 1,335 and 1,455 cm −1 appeared in the spectra of fructans, and they were related to bending vibrations and internal deformations of the methylene CH 2 -OH group from the fructose ring (Panchev et al 2011). …”

The fructans, inulin and oligofructose, were known to possess many physiologic properties. In the present study, the Box-Behnken design was used to determine the optimum extraction conditions of fructan from Eremurus spectabilis root powder (Serish) with water extraction, direct and indirect ultrasound assisted extraction methods that gave the maximum yield. Sonication amplitude (20-100 %), sonication temperature (30-70°C) and sonication time (5-40 min) were considered variables of direct and indirect ultrasound extractions while for conventional extraction the following variables were water to solid ratio (30-50 v/w), temperature (40-90°C) and time (5-40 min). A second-order polynomial model was fitted to each response and the regression coefficients were determined using least square method. There was a good agreement between the experimental data and their predicted counterparts. In addition to establishing the difference of these extraction methods, the scanning electron microscopy, Fourier-transform infrared spectroscopy, zeta potential and particle size analysis have been shown to be useful tools to investigate, approximate and predict characteristics of extracted fructan. Moreover, comparison of conventional extraction, direct sonication extraction, indirect sonication extraction showed the indirect sonication extraction is a suitable method for fructan extraction.

Serish inulin and wheat biopolymers interactions in model systems as a basis for understanding the impact of inulin on bread properties: a FTIR investigation

et al. 2015

In this study the interactions between Serish root inulin and the main biopolymer types of wheat flour namely gluten, starch and phospholipid, were investigated in different model systems using Fourier transform infrared (FTIR) spectroscopy to unravel the underlying physical mechanism by which inulin impacts dough and bread properties. Interactions of inulin with starch and phospholipid were not considerable compared to gluten, but it was also clear that the modes of these interactions varied with the type and the amount of additives used in model formulation. This study revealed that when inulin is added to gluten, water redistribution promotes partial dehydration of gluten and collapse of β-spirals into intermolecular β-sheet structures; this trans-conformations might be due to physical reasons are believed to further impact the poor quality of bread containing added inulin. Upon performing Gaussian-Lorenzian curve fitting, it was observed that by adding of inulin to model systems, the relative contribution of characteristic peaks of β-turn and intramolecular β-sheet was progressively decreased whereas intermolecular β-sheet and α-helix contents were increased.

“…Jerusalem artichoke could produce large biomass and is a potentially useful crop for producing biofuel, such as bioethanol (Long et al, 2014;Krivorotova and Sereikaite, 2014). It produces high yield of edible tubers, which are rich in inulin (10-20% of fresh tuber weight) (Gunnarsson et al, 2014;Panchev et al, 2011). Inulin from Jerusalem artichoke tubers can be used as raw material for bioethanol production (Zhang et al, 2010).…”
