Formulating Stable Natural Colors for Beverages


This opportunity is closed

Xinova seeks the disclosure of inventions that prolong the stability of natural colors in beverages without altering the taste or color profile.

Consumer preferences are driving a trend away from artificial ingredients in foods and beverages. This trend extends to food and beverage coloring agents, as consumers increasingly prefer to buy soft drinks and fruit-flavored beverages with colors derived from natural, rather than artificial, sources. Such beverages are more appealing if they are brightly colored, rather than clear, and have colors that correspond to the flavor of the beverage.

Existing natural colors for beverages tend to suffer from undesirable color fading during processing and storage. In addition, improvements to color stability using current natural additives and manufacturing methods are either short-lived or produce undesirable effects, such as changes in pH, flavor, or color.

The present RFI seeks novel solutions that can extend the shelf life of natural colors. Solutions should cover a broad color spectrum, including red, orange, yellow, and purple beverages colored from anthocyanins and carotenoids. Inventions should be in the form of natural ingredients that beverage manufacturers can easily add to ready-to-drink beverages.
