Natural Colorants: The Opportunities and Challenges In Using Them Successfully

We understand that consumer preferences and expectations related to appearance are driven in part by color.  Color also provides an indication as to the taste, quality and even safety of the foods we eat.  It can create an emotional connection such as when color aligns with expectations of familial or seasonal food favorites.  This presentation presents a case analysis of three common but sometimes difficult to solve coloring use challenges. The audience will be offered suggestions on what should be considered and what could be done to address these issues.


Clean Label Trends and Food Colorant Realities

The use of food colorants derived from natural sources has greatly increased. The local and global regulatory environments, along with common sense food safety and manufacturing practices, place limitations on what can be used and where. The industry’s decades-long use and acceptance of synthetic colorants have created performance and price expectations that influence the ease with which these naturally derived coloring materials can be adopted.  The palette of materials available, how the cultural and regulatory landscapes have affected their adoption, and the advantages and complications that are obtained through the use of naturally derived food colorants will be discussed.
