Preparation method for hyaluronic acid-gelatin-banana extract composite microsphere

Abstract

The invention discloses a preparation method for a hyaluronic acid-gelatin-banana extract composite microsphere. The preparation method comprises the following steps: washing banana skin and then preparing a homogenate from the banana skin; carrying out filtering, adding water into the obtained filtrate, and then successively carrying out ultrasonic treatment, filtering with a screen, ultrafiltration, hermetic cooling, freeze-drying and crushing; then dispersing the obtained substance, hyaluronic acid and gelatin in water and successively carrying out ultrasonic treatment, freezing and unfreezing; forming an oil phase from liquid paraffin and span-80 and dropwise adding an unfrozen solution into the oil phase; and adding a cross-linking agent, i.e., glutaraldehyde, and successively carrying out centrifugation, precipitation and washing so as to obtain the hyaluronic acid-gelatin-banana extract composite microsphere. The preparation method of the invention is simple in process and low in the cost for the raw materials. The prepared composite microsphere has biodegradability, strong water retention performance, and good loading and controlled-release effect.

AI Technical Summary

Benefits of technology

This patented technology involves making small amounts of balsa wood pulp that contain different types of substances like sugars or other compounds found naturally within plants called lignans (lucan). These substance help make paper stronger by forming tiny particles when mixed together during papermaking processes. By adding these chemicals after cooking, this new type of plant fiber becomes more durably resistant against wear caused by friction forces on its surface. Additionally, there're also some benefits associated with processing bananas containing certain nutrients: they provide antioxic properties through their flavorings, while being able to absorb harmful gases released over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the effectiveness or absorbability of certain compounds found naturally occurring within plants called flavonoids that can help prevent damage from harmful chemical reactions caused during harvesting processes like burning rice straw without losing any usefulness when used alone.
