Market Dynamics

Driver:

Growing interest in sustainable ocean-derived foods

Restraint:

Limited consumer familiarity and taste acceptance

Limited consumer familiarity with seaweed as a food ingredient and taste acceptance challenges present significant barriers to product adoption outside Asian markets where seaweed consumption is established.
