This invention discloses a method for preparing piperine starch microcapsules with sustained-release properties, belonging to the field of food processing technology. Using piperine as the core material, oleic acid as the oil phase carrier, and PG 2000 type octenyl succinate starch ester as the wall material, sustained-release piperine microcapsules are prepared through oil phase preparation, aqueous phase preparation, high-speed shearing, high-pressure homogenization, and spray drying. The microcapsules prepared by this invention have high encapsulation efficiency, small and uniformly distributed reconstituted particle size, and a stable system that is not prone to sedimentation. This allows for the slow and continuous release of piperine in simulated gastrointestinal fluid, significantly improving its poor water solubility, low stability, and low bioavailability. The resulting product can be widely used in the food, health product, and pharmaceutical fields.

This invention belongs to the field of mineral processing technology and discloses a beneficiation method for hematite ore concentrate by strong magnetic separation. Ultra-high-speed stirring at 3000 r / min to 4000 r / min is used for desorption of inhibitors, providing clean adsorption active sites for the anionic collector. Oleic acid-modified imidazoline methyl sulfate ammonium is used instead of the traditional collector, dodecylamine. Oleic acid-modified imidazoline quaternary ammonium salt compound, with a C18 unsaturated oleic acid group molecular structure, generates strong steric hindrance compared to the acyclic, large-volume groups of dodecylamine. This prevents the reagent molecules from agglomerating at high density on the bubble surface, thus avoiding the formation of thick, viscous bubbles like with traditional dodecylamine, resulting in stronger fluidity and better foam characteristics. This provides a key guarantee for achieving a stable iron concentrate grade of 66%-70% and a recovery rate of 60%-85%.
