Cephalopods as Challenging and Promising Blue Foods: Structure, Taste, and Culinary Highlights and Applications

Area of Science:

• Food science
• Soft matter physics
• Marine biology

Background:

• Foods are complex biological soft matter with hierarchical structures.
• Cephalopod muscles, as muscular hydrostats, possess challenging textures due to cross-linked collagen.
• Cephalopods are rich in umami-eliciting compounds like free amino acids and 5'-ribonucleotides.

Purpose of the Study:

• To review gastrophysical studies on cephalopod structure, texture, and taste.
• To connect basic science investigations with gastronomic potential.
• To understand cephalopods as soft materials in culinary applications.

Main Methods:

• Mechanical studies (texture analysis).
• Physicochemical measurements (protein denaturation).
• Chemical analysis (taste and aroma compounds).

Main Results:

• Cephalopod texture is influenced by their muscular hydrostat system and collagen cross-linking.
• The presence of specific compounds contributes significantly to their umami taste.
• Structure-property relationships are crucial for understanding cephalopod edibility.

Conclusions:

• Gastrophysics provides a framework for studying cephalopods as food.
• Integrating mechanical, physicochemical, and chemical analyses is essential.
• Further research can optimize cephalopod culinary applications based on scientific understanding.
