Seaweed Fermentation: A Potential Key to Enhancing Sensory Properties and Consumer Acceptance.

Area of Science:

• Food Science
• Microbiology
• Sensory Science

Background:

• Seaweed is a sustainable, nutrient-dense food source with growing global interest.
• Limited acceptance in Western markets is due to undesirable sensory attributes like marine odors, bitterness, and fibrous texture.
• Microbial fermentation is emerging as a key technology to improve seaweed's sensory profile.

Purpose of the Study:

• To review current findings on microbial fermentation of seaweed for sensory improvement.
• To synthesize the impacts of bacterial, fungal, yeast, and mixed fermentation on seaweed's flavor and aroma.
• To highlight the potential of fermented seaweed for Western markets and identify future research needs.

Main Methods:

• Review of existing literature on microbial fermentation of edible seaweeds.
• Analysis of studies detailing changes in volatile and non-volatile compounds.
• Synthesis of research on sensory outcomes and consumer acceptability.

Main Results:

• Fermentation significantly reduces off-odor volatile compounds and undesirable flavors.
• Enhances levels of umami and sweet-tasting amino acids.
• Develops more appealing fruity, floral aromas, reducing marine-like notes; mixed fermentations show synergistic benefits.

Conclusions:

• Microbial fermentation effectively improves seaweed's sensory properties, increasing its potential for Western markets.
• Fermented seaweed can be developed into functional food products for health-oriented diets.
• Standardization of sensory evaluation, comparative strain studies, and consumer validation are crucial for mainstream adoption.
