Driver

Growing Consumer Awareness About Health and Nutrition

Restraint/Challenge

Challenges in Flavor and Texture

• The adoption of algae snacks faces challenges related to flavor profiles—certain algae varieties have strong or unfamiliar tastes that require careful formulation and masking to align with mainstream consumer preferences
  • For instance, companies report that flavor optimization and texture improvement are ongoing R&D priorities, as some microalgae can impart earthiness or bitterness that may deter consumers used to conventional snack flavors
• Achieving appealing mouthfeel and crunch in algae-based snacks presents technical hurdles, often necessitating blending with grains, starches, or other plant ingredients to balance nutrition and sensory appeal
• Consumer education is required to overcome skepticism or lack of familiarity with algae, which can slow initial adoption despite its health benefits
• Scaling up production while ensuring consistent quality, taste, and texture remains complex, compounded by algae’s sensitivity to growing conditions and variability in nutrient composition
