The water-soluble, mixed-linkage β-glucan, a form of soluble dietary fibre, is considered the main biologically active component responsible for the capacity of many oat products to lower postprandial glycaemia and fasting plasma cholesterol in human subjects. The present review discusses the physical and chemical properties of oat β-glucan that are considered important predictors of these beneficial metabolic effects. In vitro modelling and animal and human studies have provided compelling… 
Comparison of cholesterol-lowering effect of β-glucan in cereals and bread
High levels of total- and LDL-cholesterol in blood are risk factors related to cardio-vascular disease. One of several measures to prevent this is consumption of the viscous soluble fibre β-glucan
Aggregation and microstructure of cereal β-glucan and its association with other biomolecules
Cereal B-Glucans: The Impact of Processing and How It Affects Physiological Responses
TLDR
This review aims at summarizing the different parameters that can affect β-glucans efficacy to improve glucose and lipid metabolism in humans.
The future of oats in the food and health continuum
TLDR
It is incumbent on scientists from multiple disciplines to advance research in a spectrum of arenas, including physico-chemical properties of oats, the impact of oats on an array of non-communicable diseases and human microbiome, agricultural practices and environments, and processing technologies that contribute to global food policies.
Impact of Oat-Based Products on Human Gastrointestinal Tract
TLDR
A long-term dietary intake of oat-based products improves human intestinal microflora, could have benefits in irritable bowel syndrome, and probable effects were seen in patients with ulcerative colitis, but this remains to be proven.
Oat bran β-glucan improves glucose homeostasis in mice fed on a high-fat diet
Oat-based functional foods are commonly produced with 1,3-β-D-glucan-enriched oat bran in which β-glucan (termed as oat bran β-glucan (OB-β-glucan)) not only co-exists with multiple other food

β-Glucan from Two Sources of Oat Concentrates Affect Postprandial Glycemia in Relation to the Level of Viscosity
TLDR
This study shows that processing oat β-glucan through enzymatic, rather than by aqueous methods, preserves the viscosity and improves postprandial glycemic control.
Physicochemical properties of beta-glucan in differently processed oat foods influence glycemic response.
TLDR
Characterizing the physicochemical properties of beta-glucan in bioactive foods aids functional food development by identifying the highest efficacy in attenuating the peak blood glucose response (PBGR) and depolymerization in bread and pasta reduced beta-Glucan bioactivity.
Physicochemical properties of oat β-glucan influence its ability to reduce serum LDL cholesterol in humans: a randomized clinical trial.
TLDR
The physicochemical properties of oat β-glucan should be considered when assessing the cholesterol-lowering ability of Oat-containing products; an extruded breakfast cereal containing 3 g oatβ- glucan/d with a high-MW or a medium-MW lowered LDL cholesterol similarly by 5%, but efficacy was reduced by 50% when MW was reduced to 210,000 g/mol.
Processing affects the physicochemical properties of beta-glucan in oat bran cereal.
TLDR
Microscopic examination showed that as the extrusion conditions were made more severe, to cause depolymerization, the integrity of the cell walls was lost and beta-glucan dispersed throughout the cereal and the apparent viscosity in the physiological extract dropped.
Molecular Weight Distribution of β-Glucan in Oat-Based Foods
ABSTRACT Oats, different oat fractions as well as experimental and commercial oat-based foods, were extracted with hot water containing thermostable α-amylase. Average molecular weight and molecular
Interactional effects of β-glucan, starch, and protein in heated oat slurries on viscosity and in vitro bile acid binding.
TLDR
It is illustrated that β-glucan was the major contributor to viscosity and in vitro bile acid binding in heated oat slurries; however, interactions with other components, such as protein and starch, indicate the importance of evaluating oat components as whole system.
Reducing Beta-Glucan Solubility in Oat Bran Muffins by Freeze-Thaw Treatment Attenuates Its Hypoglycemic Effect
ABSTRACT The viscosity of soluble fibers such as β-glucan depends on their concentration in solution and molecular weight (MW) distribution. We investigated whether freezing treatment of oat bran
