While the world population is steadily increasing, capacity of Earth to renew its resources continuously declining. Consequently, bioresources required for food production are diminishing and new approaches needed feed current future global population. In last decades, scientists have developed novel strategies reduce loss waste, improve production, find ingredients, design build structures, introduce digitalization in system. this work, we provide a general overview on circular economy,...
Xylan is a biopolymer readily available from forest resources. Various modification methods, including oxidation with sodium periodate, have been shown to facilitate the engineering applications of xylan. However, procedures are often optimized for semicrystalline high molecular weight polysaccharide cellulose rather than lower and amorphous This paper elucidates procedure periodate xylan into dialdehyde its further reduction dialcohol form focused on work up. The oxidation-reduction...
The recovery of softwood galactoglucomannans (GGM) by pressurized hot water extraction and further concentration membrane filtration followed spray drying yield biopolymers suitable as raw materials for renewable products. GGM are often characterized having low viscosity in excellent emulsion stabilizing capacity, enhanced lignin structures co-extracted with GGM. To reduce fouling during subsequently to increase product yield, the pH temperature liquor can be increased, but effects such...
Abstract Lignocellulosic materials from the forest industry have shown potential to be used as sustainable hydrocolloids stabilize emulsions for many applications in life science and chemical industries. However, effect of wood species recovery method on product’s properties ability isolated lignocellulosic compounds is not well understood. Hemicelluloses, abundant side stream, exhibit differences their water solubility, anionic character, lignin content, degree acetylation. Here, we...
Glucuronoxylans (GX), particularly crude fractions obtained by pressurized hot water extraction of birch wood, act as potent emulsifiers and stabilizers against physical separation lipid oxidation. Herein, we studied the adsorption GX on hydrophobic interfaces to correlate their multicomponent character towards formation interfacial layers in emulsions. Dynamic tension (DIFT) quartz crystal microgravimetry with dissipation monitoring (QCM-D) were applied various results compared those from...
Wood hemicelluloses have been used as a wall material for spray-dried microencapsulation of polyphenols. Nevertheless, their incomplete water solubility could negatively impact encapsulation efficiency (EE) and the formation complete protective layer, which might be alleviated synergistically by combining them with carboxymethylcellulose (CMC). We explored effects CMC addition (0.5–3.0%, w/w WM) on capacity galactoglucomannans (GGM) glucuronoxylans (GX) to retain bioactive compounds bilberry...
Emulsions are commonly used to fortify beverages with oil-soluble nutrients. Such emulsions must be physically stable, prevent the cargo nutrient from chemical degradation, and release at right time during digestion. Wood hemicelluloses, their proven capability in producing nanoemulsions preventing oil oxidation, have potential facilitate such a fortification method. These hemicelluloses unique, as presence of residual lignin was essential functionality. However, structural interplay between...
