Roasted fish reaction flavor by plant-based ingredients

Area of Science:

• Food Science
• Sensory Science
• Biochemistry

Background:

• The growing demand for plant-based meat alternatives necessitates the development of authentic flavor profiles.
• Currently, no commercial plant-based products effectively replicate the taste of roasted fish.
• Creating realistic flavors is crucial for the advancement of the plant-based food industry.

Purpose of the Study:

• To identify key ingredients and conditions for creating a plant-based roasted fish flavor.
• To investigate the chemical precursors and reaction mechanisms involved in flavor generation.
• To identify the specific aromatic compounds contributing to the roasted fish flavor profile.

Main Methods:

• A specific blend of amino acids (lysine, leucine, glutamic acid, alanine, cysteine), glucose, and algae oil (rich in docosahexaenoic acid) was heated under low pH conditions.
• Analysis of key aromatic compounds generated during the heating process.
• Investigation of reaction pathways including lipid oxidation, lipid degradation, and Maillard reactions.

Main Results:

• A blend of selected plant-based ingredients, when heated in low pH, successfully generated a flavor reminiscent of roasted mackerel.
• Identified key volatile compounds contributing to the flavor, including isovaleric acid, octanoic acid, and various aldehydes and furans.
• These compounds were found to originate from lipid oxidation, lipid degradation, and Maillard reactions.

Conclusions:

• A novel method for creating a plant-based roasted fish flavor has been established.
• The study elucidates the chemical basis for this specific plant-based flavor.
• This research is vital for the continued innovation and market growth of plant-based meat products.
