ABout Us


The vast majority (90%) of Americans are falling short of their dietary fiber needs despite growing awareness of its many health benefits. Food manufacturers have yet to find the perfect fiber ingredient – one that is natural, functional, and versatile – to fill the 2-million-ton annual fiber gap in the US alone. 

Meanwhile, nature’s best dietary fiber, arabinoxylan, has laid dormant in plant materials left behind and processed out of our modern food system. Arabinoxylan is an exceptional soluble dietary fiber with clinically proven health benefits and superior tolerance in the gut. 

Only COMET has the patented upcycling technology needed to unlock arabinoxylan’s full potential and make it available in our proprietary line of ARRABINA dietary fibers. ARRABINA’s versatility makes it easy to add the clinically proven benefits of arabinoxylan to ANY food/beverage/supplement application and help close the fiber gap.

In the united states alone...

Only comet can meet this opportunity:
