“…Intensity of characteristic β-glucan bands at 1375, 1312, 1100, 1065, 1038 and 890 cm −1 [ 11 , 34 , 39 ] remain unchanged in all samples throughout the hot water extraction process. β-1,3/1,6-glucan characteristic band at 1160 cm −1 is not observed in our samples [ 34 , 36 ]. However, another band, which represents α-linked glucans is located at 1155 cm −1 [ 34 , 40 ].…”

“…Broad region between 3600–2600 cm −1 can be assigned to O-H bond, N-H bond at 3500–3100 cm −1 and CH bond at 3000–2800 cm −1 [ 27 , 34 , 35 , 36 ]. Characteristic amide regions are found at 1720–1620 cm −1 (amide I), 1570–1470 cm −1 (amide II) and 1350–1250 cm −1 (amide III) [ 16 , 19 , 34 , 37 ].…”

“…The chitin characteristic peak is indicated by a shoulder near 3100 cm −1 , which is attributed to N-H stretching [ 36 ] and shoulder at 1025 cm −1 , which correspond to β-1,4-glycosidic linkage [ 35 , 48 ]. Other chitin characteristic bands are located and are hidden by protein bands at 1538 cm −1 (NH), 1375 cm −1 (CH 3 ) and 1312 cm −1 (CN) [ 40 , 51 ].…”

FT-IR Method Limitations for β-Glucan Analysis

β-glucans are known as biological response modifiers. However, different sources can result in structural differences and as a result differences in their biological activity. The hot water extraction method allows to obtain, high molecular weight β-glucans without altering their structure by using strong chemicals, such as alkalis or acids. Analysis of β-glucans by FT-IR and NMR spectroscopy in solid state is superior to analysis in solution as it allows researchers to study the preserved structure of the extracted polysaccharides. FT-IR spectroscopy was used in this study to make side-by-side comparison analysis of hot water extracted β-glucans from different yeast sources. NMR spectroscopy was used to confirm findings made by FT-IR spectroscopy. Extracted β-glucans exhibit characteristic structure of β-1,3/1,6-linked glucans with noticeable levels of proteins, possibly in a form of oligopeptides, chitin and other impurities. β-glucans obtained from C. guilliermondii, P. pastoris and S. pastorianus exhibited higher protein content. Differences in mannan, chitin and α-glucan content were also observed; however, the species-specific structure of obtained β-glucans could not be confirmed without additional studies. Structural analysis of high molecular weight β-glucans in solid state by FT-IR spectroscopy is difficult or limited due to band intensity changes and overlapping originating from different molecules.

“…β-glucan regulates the gastrointestinal transit rate after meals and starch digestion to dilute blood sugar level through changes in the glycemic index, thereby reducing the insulinemic response in diabetes [ 41 , 45 ]. In addition, β-glucan has various physiological effects such as preventing cardiovascular diseases by controlling the blood pressure and anti-obesity and anti-cancer effects (e.g., prevention of colorectal cancer) [ 18 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ]. It lowers low-density lipoprotein (LDL) cholesterol level in the blood and elevates high-density lipoprotein (HDL) cholesterol level to help maintain normal blood lipid concentration and body weight [ 56 ].…”

Oats (Avena sativa L.) are rich in protein, fiber, calcium, vitamins (B, C, E, and K), amino acids, and antioxidants (beta-carotene, polyphenols, chlorophyll, and flavonoids). β-glucan and avenanthramides improve the immune system, eliminate harmful substances from the body, reduce blood cholesterol, and help with dietary weight loss by enhancing the lipid profile and breaking down fat in the body. β-glucan regulates insulin secretion, preventing diabetes. Progladins also lower cholesterol levels, suppress the accumulation of triglycerides, reduce blood sugar levels, suppress inflammation, and improve skin health. Saponin-based avanacosidase and functional substances of flavone glycoside improve the immune function, control inflammation, and prevent infiltration in the skin. Moreover, lignin and phytoestrogen prevent hormone-related cancer and improve the quality of life of postmenopausal women. Sprouted oats are rich in saponarin in detoxifying the liver. The literatures have been reviewed and the recent concepts and prospects have been summarized with figures and tables. This review discusses recent trends in research on the functionality of oats rather than their nutritional value with individual immunity for self-medication. The oat and its acting components have been revisited for the future prospect and development of human healthy and functional sources.

Ferulic acid (FA) is a hydroxycinnamic acid known for its strong antioxidant activity and potential benefits for intestinal health. However, its poor water solubility and instability limit its effectiveness. To address these issues, different ways have been explored to protect FA against degradation and further exert its potential benefits. This review discusses the absorption and metabolism of FA in the gut, as well as its potential impact on intestinal health. It also compares different intestinal delivery systems, such as nanoparticles, electrospun nanofibers, microcapsules, cross‐linked polymer gels, and Pickering emulsions, which can improve the solubility, stability, and bioavailability of FA in the gastrointestinal tract. This comprehensive review provides valuable insights for using FA in food, pharmaceutical, and nutraceuticals products.
