Extraction of Soluble Dietary Fiber from Sunflower Receptacles (<i>Helianthus annuus</i> L.) and Its Alleviating Effect on Constipation in Mice.

ABSTRACT:

Background/objectives

Sunflower receptacles are the main by-product of the processing of Helianthus annuus L.

Methods

In this study, several extraction methods of soluble dietary fiber (SDF) from sunflower receptacles were evaluated, and then, the physicochemical structure and functional properties of these SDFs were examined. Finally, a mouse constipation model was established to explore its therapeutic potential for constipation.

Results

The results showed that the SDF yield of citric acid extraction and enzyme extraction was better than that of hot-water extraction. Structural characterization showed that the three SDF functional groups were similar and amorphous, while the surface distribution of the SDF obtained by the citric acid extraction method (ASDF)
