Summary: This study compared four extraction methods (UE, HWE, ME, and MUE) for extracting beta-glucan from hull-less barley bran, finding that MUE had the highest extraction yield and shorter extraction time, with beta-glucans extracted showing higher molecular weight. Additionally, the physicochemical properties of beta-glucans varied depending on the extraction method used.

Summary: This study characterized the proteins associated with beta-glucan (BG) synthesis and accumulation during hull-less barley seed development, revealing key biological processes related to BG accumulation such as cell wall modification, carbon and energy metabolism, and polysaccharide metabolism. The study also identified important proteins involved in BG synthesis and pathways providing energy and reducing power for BG storage. The results provide insights into the mechanisms of BG synthesis and accumulation during hull-less barley seed development.

Summary: The study found that different barley genotypes contain rich bioactive compounds and antioxidant capacity after sequential pearling, with husks having the highest antioxidant content. Even though current regulations require the elimination of inedible husks from human foods, they should be considered as valuable materials for animal feeds due to their high content of beneficial substances.

Summary: The interactions between beta-glucan and starch in barley-based foods and brewing are important. We compared beta-glucans from waxy and normal barley varieties and their effects on starch characteristics and mashes. Beta-glucan reduced the viscosities of starches, lowered pasting temperatures, and increased resistant starch. Unmalted waxy barley had higher filtration rates due to faster digestion and open filter passages. The effects of beta-glucan vary with type and content, while starch type has a more significant impact.

Summary: The aim of the research was to characterize the changes of polysaccharides in hull-less barley and wholegrain wheat breads and analyze their impact on the physical parameters of bread. The use of barley sourdoughs for wholegrain wheat bread dough fermentation resulted in reduced specific volume and porosity, doubled beta-glucan content, and no significant increase in hardness. The composition of polysaccharides was affected by the type of flour and fermentation method used.

Summary: Solid-state fermentation using hulled barley was carried out to produce enzymes and beta-glucan. The optimal composition of the basal medium was determined through one-factor-at-a-time experiments, and the modified synthetic medium composition for liquid-state fermentation was obtained. The optimal pretreatment conditions of hulled barley in solid-state fermentation were evaluated, resulting in high production of fungal biomass, amylase, protease, and beta-glucan.

Summary: Arabinoxylan (HBAX-60) was fractionated from alkaline-extracted arabinoxylan (HBAX) in hull-less barley, composed mainly of arabinose and xylose with a low-branched xylan backbone and other residues. Analysis showed a random coil conformation in solution, providing insights for further research and applications of this arabinoxylan.

Summary: Under different microwave conditions, waxy hull-less barley kernels and their isolated starches undergo changes in morphology, particle size, digestibility, rheological properties, and molecular structure. Microwave treatment increases starch digestibility, particle size, and alters rheological properties, while maintaining relatively stable chain-length distribution. The primary effects of microwave treatment may include loosening the molecular structure and cutting main chains of amylopectin.

Summary: Naked barley is a versatile cereal crop grown worldwide for feed, food, and malting. This study investigated the grain yield, yield components, and quality traits of 25 naked barley genotypes over three consecutive years. The analysis showed that both the years and genotypes had a significant impact on the examined characteristics.

Summary: In this study, near-infrared (NIR) spectroscopy combined with Chemometrics was used to predict the beta-glucan content in oats rapidly and non-destructively. The results showed that the wavelength region 700-1300 nm is sufficient for predicting beta-glucan content accurately.

Summary: The study showed that microwave irradiation of hull-less barley kernels and their isolated starches resulted in less thickening and more thinning effects, possibly due to more amylose breakdown in in-kernel starches. Additionally, microwave treatment led to changes in the properties and molecular structures of starch pastes, with in-kernel starches showing higher strength and harder gel after irradiation. The molecular size distributions of treated starches indicated degradation of amylopectin molecules, while no new peaks appeared in any of the treated starches.
