This invention relates to the field of functional food processing technology, specifically disclosing a functional asparagus powder with high saponin content and its preparation method. The method includes the following steps: asparagus is sliced ​​and microwaved to deactivate enzyme activity; after pulping, a composite regulator aqueous dispersion is added; the pH is adjusted and a cellulose complex enzyme is added for enzymatic hydrolysis; then, it is pre-frozen and vacuum freeze-dried; finally, it is pulverized, sieved, and packaged under a nitrogen atmosphere. The composite regulator can dynamically stabilize and protect saponin molecules through temperature-responsive behavior during processing, significantly reducing thermal degradation. The resulting asparagus powder has a saponin content of 72-85 mg / g and is rich in flavonoids, phenols, and soluble dietary fiber. This product can be used in functional foods that improve sleep. When added at a 4% level to bread, noodles, or meal replacement porridge, animal experiments have verified that it can significantly prolong sleep time and increase the incidence of sleep in mice, exhibiting high nutrient retention and good stability.

This invention relates to high-temperature, high-strength zirconium-hafnium yttrium solid solution oxide continuous fibers, their preparation methods, and applications. In these continuous fibers, hafnium oxide replaces some zirconium oxide sites in a yttrium-stabilized zirconium oxide lattice, forming a single solid solution phase containing zirconium, hafnium, yttrium, and oxygen. The three metal elements are randomly distributed in the lattice, and the phase is either tetragonal or cubic. Using poly(zirconium acetylacetonate) and poly(hafnium acetylacetonate) as the zirconium and hafnium sources respectively, a spinneret is prepared with the addition of a stabilizer. Spinning is then performed to obtain precursor continuous fibers. After vapor pressure desorption and medium-temperature steam treatment, primary crystallized continuous fibers are obtained, followed by high-temperature ultrafast heat treatment to obtain the final product. The zirconium-hafnium yttrium solid solution oxide continuous fibers of this invention exhibit good high-temperature stability. After being held at 1500 °C for 120 min, they still possess high mechanical strength and excellent flexibility, with an average tensile strength of over 1.0 GPa for each filament. They can be used as high-temperature structural reinforcement materials and high-temperature flexible thermal insulation materials.
