Title: Graciela Wild Padua: Innovator in Flavor Encapsulation and Corn Zein Resin Manufacturing

Introduction

Graciela Wild Padua is a notable inventor based in Champaign, IL (US). She has made significant contributions to the fields of food science and materials engineering. With a total of 3 patents, her work focuses on innovative methods for flavor encapsulation and the manufacturing of corn zein resin products.

Latest Patents

One of her latest patents is titled "Methods of flavor encapsulation and matrix-assisted concentration of aqueous foods and products produced therefrom." This invention involves mixing flavor with a prolamin solution and drying it into powdered forms of encapsulated flavor. In one embodiment, flavor and zein are separately dispersed in an alcohol-water mixture before mixing. Another embodiment involves mixing an aqueous food containing bioactive components with the prolamin solution, which initiates the precipitation of the prolamin and concentrates the bioactive components. The resulting powdered forms of encapsulated flavor include these bioactive components. Additionally, a two-phase drying process may be employed to produce the powdered form through evaporation-induced self-assembly of zein microstructures.

Another significant patent is the "Method of manufacturing improved corn zein resin films, sheets, and articles." This invention describes the creation of sheets, films, and articles from a corn zein resin. A wet corn zein resin is formed by combining corn zein and a fatty acid, which is then cold rolled into sheets. These sheets are dried, and the dried zein resin is processed to create various articles of manufacture.
