Physicochemical properties of tiger nut (Cyperus esculentus L) polysaccharides and their interaction with proteins in beverages

Effect of Cyperus esculentus polysaccharide on Cyperus esculentus starch: Pasting, rheology and in vitro digestibility

“…It can be observed that the absorption peaks near 3400 cm −1 indicate the stretching vibration of the O—H group. The characteristic absorption peaks of polysaccharides were observed near 2930 cm −1 , while 1655 cm −1 represents the asymmetric absorption peak of the C O bond, and 1417 cm −1 is the absorption peak of the C—H bond ( Yu et al, 2023 ). Within the range of 4000–400 cm −1 , the shapes and positions of the infrared absorption peaks of the different complexes are very similar, with no emergence of new peaks or disappearance of characteristic peaks.…”

“…CEP has a linear chain and branched chains containing a variety of functional groups, which can inhibit the generation of free radicals, enhance the activity of antioxidant enzymes, and improve the antioxidant capacity ( Hernández-Olivas et al, 2022 ). It also has the advantages of lowering blood lipids and regulating immunity ( Yu et al, 2023 ). Moreover, the regulation of blood glucose by CEP has received widespread attention.…”

Ultrasound-assisted extraction and physicochemical properties of starch from Cyperus esculentus tubers

“…Aydar et al (2020) conducted a detailed analysis on the production process, bioavailability, and market share of C. esculentus and other plant-based dairy substitutes. Recent studies have shown that adding polysaccharide extracts from C. esculentus to protein drinks exhibits better stability than regular protein drinks (Yu et al 2023). Chukwuma et al (2010) observed the presence of alkaloids, cyanosides, resins, tannins, sterols, and saponins in the raw C. esculentus tubers, confirming that the tubers contain important nutrients and are essential nutrients for human health.…”
