Citrulline Blocker Innovation

We received a request from a leading nutritional product manufacturer who was unhappy with the negative taste perception received when using a high dose of citrulline. Keeping the level of citrulline high was equally as important as a great-tasting product to the manufacturer to make sure their customers were getting the functional benefits they crave. Working with the manufacturer in our lab, we were able to handcraft a flavor modification solution that:

  • Blocked negative citrulline tastes
  • Easily blended into their flavor system
  • Kept the customers desired label declaration

Flavor modification is the process of changing the perception of tastants on the tongue in order change how one perceives a flavor. Reasons why you might consider flavor modification are to either eliminate the off-tastes of a product, enhance sweetness, help improve nutrition, or reduce costs. We like to break down flavor modification into three categories- masking, blocking, and sweetness enhancing.

The intention of a masker is to mitigate off-notes while providing a neutral flavor profile. The approach involves using FEMA-GRAS materials that provide an aroma and/or taste attribute to lower ones perception of off-notes.  These can include common flavor ingredients as well as other materials including sweeteners, acids, and salts.

Blockers are able to change taste attributes through a chemical process.  An ingredient that acts as a blocker will interact by either binding with the bitter taste receptor on the tongue, or binding with the “offending” tastant. This process helps the tastant not be perceived by the tongue, therefore blocking the bitter taste or off-notes

Sweetness enhancers can help potentiate the sweet perception of natural, non-caloric sweeteners in addition to common sugars. These flavor modifiers are easily consolidated into other flavors and provide a cost-effective solution for adding sweetness to a product.
