Abstract

The invention discloses a yeast microcapsule of globe artichoke polyphenol and a preparation method of the yeast microcapsule. A yeast microcapsule product is prepared from freeze-dried powder of globe artichoke serving as a core material and yeast cells serving as an embedding wall material through water bath constant-temperature oscillation, centrifuging and freeze-drying, wherein the freeze-dried powder of globe artichoke is obtained through extraction, purification and freeze-drying. Yeast cells are rich in nutrition self, and due to microencapsulation of the yeast cells, the antioxidant activity of polyphenol is maintained, and furthermore nutrient substances of yeast are supplied, so that the yeast microcapsule has the characteristics of slow medicine release, high bioavailability, relatively simple preparation process and is suitable for industrial large-scale production, and meanwhile ideas and directions are provided for further application of polyphenol.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a yeast microcapsule of artichoke polyphenols and a preparation method thereof. Background technique [0002] Artichoke stems and leaves are rich in polyphenolic compounds, including caffeic acid, chlorogenic acid, rutinose, luteolin (cynaroside), etc. The main active ingredients can be used as raw materials for medicines and health products, and can also be used as medicines to prevent and treat insufficient bile secretion and hepatitis. In recent years, more research has focused on the prevention and treatment of chronic diseases such as anti-oxidation, lowering blood fat, and preventing hypertension. There are many polysaccharides in the crude polyphenol extract, but its biological activity is also very unstable, which limits its application. Using microcapsule technology can solve the above problems. [0003] Microcapsules use the wall material to embed the core materia...
