Method for preparing electrospraying particles to improve stability of polyphenol

Abstract

This invention provides a method for preparing electrospraying particles to improve stability of polyphenol including the following steps: preparing a pectin-silica composite; adding polyphenolic compounds into the pectin-silica composite to prepare a core solution; and coaxial electrospraying the core solution and a shell solution to prepare electrospraying particles loaded polyphenol. This method utilizes a pectin-silica composite as a polyphenol loading carrier, improves the encapsulating efficiency of polyphenols, reduces the contact probability of polyphenols with oxygen and water, and improves the stability of polyphenols; and an acidic aqueous solution is used as a shell solution to synergize with the pectin-silica composite to further improve the stability of polyphenols.
