Bitter blocker that enhances sweetness 

The Perfect Curve of Subtle Sweetness

TruMask™ bitter blocker is the next generation of taste enhancement technology. TruMask™ enhances bitter blocking capabilities by also providing a near instantaneous sweetness on the tongue that naturally rounds out the flavor profile. TruMask™ can be used in unison with sweeteners or as a stand alone to bring a hint of sweetness while blocking negative taste attributes. 

We tend to recommend TruMask™ for sugar-free products and with products looking to strengthen their sweetness profile. TruMask™ bitter blocker performs well in traditional mediums where you would have originally found ample sugar.
