Summary: This study investigated the impact of 8-glucan on bile acid binding, showing that viscosity and 8-glucan concentration are key factors affecting bile acid mobility. The 8-glucan gel network can trap bile acids, while the hydrolysis of phytate can increase bile acid binding by improving 8-glucan extractability.

Summary: The aim of this study was to investigate the effect of sprouted oats substitutions on the in vitro digestibility of starch in wheat bread. The study found that polyphenols and gamma-aminobutyric acid increased, while starch and beta-glucan content gradually decreased in wheat bread enriched with 20% sprouted oat flour. The specific volume of the mixed bread reached its maximum after sprouting for 72 hours. The microstructure revealed that small type B wheat starch and oat starch were wrapped in protein-beta-glucan complexes after baking. This study suggests that properly sprouting has the potential to obtain nutritional bread with low starch digestibility.

Summary: During the processing of hulled Reins and hulless Lamont oats, the distribution patterns of nutrients varied while those of AVAs were influenced by variety and specific AVAs. Pearled oats contained lower nutrients and higher beta-glucan and starch compared to whole grains, with a different AVA composition.

Summary: This study showed that the addition of wheat bran and oat bran negatively affected the texture and color of bread, while the addition of beta-glucan did not have a significant impact. The beta-glucan in oat bran may be the key component in reducing the glycemic index of whole oat bread.

Summary: The present study examined the structure of acorn starch and how non-starch nutrients affect its physicochemical properties and digestibility. Results showed that the crystallinity of acorn flour decreased after various treatments, which also led to a decrease in gelation temperature and reduced interactions between starch granules. Endogenous proteins, fats, and beta-glucans played a key role in reducing the digestibility of acorn starch by forming complexes and inhibiting hydrolysis.

Summary: This study investigated the effects of removing non-starch constituents on the in-vitro digestibility of oat bran. Results showed that removing lipids, proteins, and beta-glucan increased the digestibility, and steaming and microwaving had significant effects on protein solubility.

Summary: The inclusion of oats in white wheat salted noodles can lead to a slower digestion rate, potentially offering health benefits. The process of noodle-making and subsequent cooking affects the concentration and solubility of oat beta-glucan, impacting starch digestibility. This study suggests that interaction between beta-glucan and protein alters noodle microstructure, influencing digestibility.

Summary: The study investigated the effects of high hydrostatic pressure (HHP) treatment on the properties of oat starch/beta-glucan mixtures, finding significant changes in crystal structure, viscosity, and particle size. After HHP treatment, the complexes were distributed in the same region with similar properties, indicating a consistent transformation in the mixture system.

Summary: This study produced a novel plant-based milk from quinoa with the addition of oat beta-glucan (OGB), which efficiently prevented phase separation and improved stability. The optimal OGB concentration was found to be 16%, as it led to higher apparent viscosity, narrower particle distribution, and improved storage stability.

Summary: Different degradation methods (acid and oxidative) result in distinctive structures and functionalities of oat beta-glucan oligosaccharides, affecting properties such as viscosity, fat binding capacity, and glucose availability. Acid or oxidative degradation of oat beta-glucan enhances its antioxidant, antibacterial, and hypoglycemic effects.

Summary: The study found that different levels of hulless barley and addition of different levels of β-glucanase (BGase) can impact the growth performance of broiler chickens challenged with coccidiosis. Overall, hulless barley may decrease body weight gain in broilers, while BGase can alleviate some of these negative effects, especially in diets with high levels of hulless barley.

Summary: Oats are a nutrient-rich food with potential health benefits. A biochemical assessment of 112 oat genotypes revealed significant variability in phenol, beta-glucan, calcium, zinc, iron, and manganese content among genotypes. Genotypes OS-6, HFO-638, HFO-915, and HFO-918 showed higher levels of iron and zinc, while genotypes OS-403 and OL-1804 had elevated levels of manganese and zinc. Certain genotypes with low phytic acid were found to have high crude protein and beta-glucan content. The study also found a positive correlation between copper and iron, manganese, and calcium content. These findings have implications for the development of value-added oat food products and new oat varieties.

Summary: The study found that the effects of calcium caseinate (CaCn) on oat starch were closely related to the concentration of CaCn, with higher concentrations leading to increased pasting properties, higher viscosity, and decreased stability. High levels of CaCn also affected the thermal and structural properties of oat starch.
