“…The FTIR spectra of the samples contain all bands characteristic of heteropolysaccharides (Fig. 3), which are described in detail in [18,[32][33][34][35]. The absorption bands at 3433 and 2924 cm -1 refer to the O-H and C-H stretching, respectively.…”

“…Chadni et al [16] studied the hemicelluloses isolated from spruce sawdust in a neutral medium at 100 °C for 1 h with presoaking and reported an M n value of 20.730 kDa, an M w value of 37.870 kDa, and a PDI of 1.82 for them. In the study [18], the same research team examined the effect of steam explosion conditions on the extraction of hemicelluloses from spruce sawdust,the weight-average molecular weight M w of hemicelluloses obtained in a neutral medium was found to be 9-27 kDa and the PDI value was 2.3-2.6. The work [40] studied the hightemperature extraction of galactoglucomannan from pine wood.…”

“…In recent years, the extraction of hemicelluloses from wood raw materials has been studied intensively. Hemicelluloses were isolated by the hot-water extraction [12,13], hot pressurized water pretreatment [14], alkaline hydrogen peroxide pretreatment [15], microwave-assisted extraction under atmospheric pressure [16,17], and steam explosion extraction [18].…”

The composition and physicochemical characteristics of polysaccharides extracted from spent liquors of catalytic and noncatalytic delignification of larch wood in the acetic acid-hydrogen peroxide medium were studied. The following were used as catalysts: (NH 4 ) 6 Mo 7 O 24 , MnSO 4 , TiO 2 , and ZnSO 4 . The structure of polysaccharides was identified by FTIR and NMR spectroscopy. Their composition was established using gas chromatography, and the physicochemical characteristics were studied using gel permeation chromatography, scanning electron microscopy, thermogravimetric analysis, gas adsorption, and elemental analysis. It was shown that in the process of oxidative delignification, a significant amount of hemicelluloses and arabinogalactan passes into the spent liquor. The yield of polysaccharides was up to 16.9 wt%. Polysaccharides had a weight-average molecular weight of up to 22.9 kDa and a narrow molecular weight distribution.

“…As a result, the high temperature/low duration conditions of SE allow the extraction of thermally labile mid-polar compounds such as phenolics or polysaccharides with a low degradation rate due to the short reaction times. Recent examples from literature include extraction of sterols and phenols from olive pomace ( Ustundag et al, 2018 ), bioactive compounds from strawberry extrudate (ascorbic acid, anthocyanins, ellagitannins, different vitamins, carotenoids, folic acid, and flavonoids) ( Munoz-Arjona et al, 2020 ), highly acetylated mannanes and xylanes from wood ( Mougnala Moukagni et al, 2021 ; Chadni et al, 2019 ).…”

Steam Explosion (SE) is one of the most efficient and environmentally friendly processes for the pretreatment of lignocellulosic biomass. It is an important tool for the development of the biorefinery concept to mitigate the recalcitrance of biomass. However, the two distinct steps of SE, steam cracking and explosive decompression, leading to the breakdown of the lignocellulosic matrix have generally been studied in empiric ways and clarification are needed. This mini-review provides new insights and recommendations regarding the properties of subcritical water, process modeling and the importance of the depressurization rate.

“…Examples of them are ultrasound-assisted extraction (UAE), 7 microwave-assisted extraction, 8 and subcritical and supercritical water or CO 2 extraction, 9 as well as utilization of pulsed electric fields 10 or steam explosion techniques. 11 They all focus on process intensification and cost reduction, while they maintain safety and low impact on the environment, frequently, by minimizing waste formation and using water recirculation. 12 However, the chemical composition of the treated biomass and potential biological activity of the isolated bioproducts play key roles in selecting the appropriate extraction technique.…”

Optimization of Ultrasound-Assisted Extraction of Functional Food Fiber from Canadian Horseweed (Erigeron canadensis L.)

Much attention has been recently paid to the design of sustainable processes for the production of functional food additives based on renewable resources. Thus, methods for incorporation of green techniques in treatment of undeveloped biomass, resulting in value-added bioproducts, are in great demand. We focus here on the biological activity and chemical properties of Erigeron canadensis (horseweed) functional food fiber, which can be strongly affected by the extraction procedure employed. In the present contribution, we report on an attempt to introduce a sustainable and energy-efficient ultrasound-assisted extraction process, followed by a multistep purification procedure, resulting in a macromolecular plant-derived anticoagulant agent. The most efficient ultrasound-assisted process was determined by optimization through the response surface methodology I -optimal design (2 4 ). A comparison with the conventional procedure for retrieval of horseweed biomacromolecules revealed that the optimized ultrasound-assisted extraction was more sustainable, with the cumulative energy demand being 38% lower (12.2 MJ), 6.6 times reduced water consumption (3.5 L), and 1.2 times shorter (41 h) total processing time. Moreover, the optimal ultrasound-assisted extraction process-purified food fiber turned out to be a better anticoagulant agent by 57%, compared to a conventional product, and was a more selective indirect inhibitor of the human Xa coagulation factor.
