Title: The Innovative Mind of Kurt Bernhard: Pioneering the Field of Carotenoid Technologies

Introduction

Kurt Bernhard, an esteemed inventor based in Lupsingen, Switzerland, has made significant contributions to the field of carotenoid technology with a total of five patents to his name. His work revolves around the conversion of lutein into zeaxanthin, which has widespread applications in the food industry, particularly in the pigmentation of animal products.

Latest Patents

Among Bernhard's latest patents is a groundbreaking process for manufacturing zeaxanthin from lutein. This innovative method utilizes base-catalyzed isomerization to convert lutein or its esters into zeaxanthin, executed by heating lutein-containing material in a specific aqueous solution. The process requires temperatures between 50°C and 120°C and includes a phase transfer catalyst when using hydrocarbon-based organic solvents. Given the importance of carotenoids as natural pigments, zeaxanthin is preferred for its ability to produce a more vivid golden yellow pigmentation in poultry, fish, and crustaceans than lutein.

Another of Bernhard's notable patents discusses methods for pigmenting animal feeds with various carotenoids. This involves creating feed formulations that enhance the color of poultry, fish, and crustaceans, leading to visually appealing and marketable products. The inclusion of specific carotenoids not only impacts the coloration but also contributes to the overall quality of these animals' meat and eggs.
