| description | <i>Cistanche deserticola</i> residues are by-products of the industrial production of <i>Cistanche deserticola</i>, which are currently often discarded, resulting in the waste of resources. In order to achieve the efficient utilization of <i>Cistanche deserticola</i>, dietary fiber from <i>Cistanche deserticola</i> residues was extracted chemically and the optimization of the extraction conditions was performed, using the response surface methodology to study the effects of the NaOH concentration, extraction temperature, extraction time, and solid–liquid ratio on the yield of water-soluble dietary fiber (SDF). The structural, physicochemical, and functional properties of the dietary fiber were also investigated. The results showed that the optimal conditions were as follows: NaOH concentration of 3.7%, extraction temperature of 71.7 °C, extraction time of 89.5 min, and solid–liquid ratio of 1:34. The average yield of SDF was 19.56%, which was close to the predicted value of 19.66%. The two dietary fiber types had typical polysaccharide absorption peaks and typical type I cellulose crystal structures, and the surface microstructures of the two dietary fiber types were different, with the surface of SDF being looser and more porous. Both dietary fiber types had good functional properties, with SDF having the strongest water-holding capacity and the strongest adsorption capacity for nitrite, cholesterol, sodium cholate, and glucose, while IDF had a better oil-holding capacity. These results suggest that <i>Cistanche deserticola</i> residues are a good source of dietary fiber and have promising applications in the functional food processing industry. |
