Development and optimization of plant-based meat analogues using mycelium-based scaffolds for improved texture and nutrition.

Project Abstract

This study presents the development and optimization of plant-based meat analogues utilizing mycelium-based scaffolds to achieve improved textural properties and enhanced nutritional profile, addressing growing consumer demand for sustainable, protein-rich foods with reduced environmental impact. The research integrates mycelial networks derived from selected edible mushrooms with structured plant-based matrices to fabricate bio-composites that mimic the fibrous architecture and juiciness of conventional meat while delivering comparable essential amino acids, micronutrients, and flavor release. A two-pronged approach was employed scaffold design and bioprocess integration, followed by formulation optimization using response surface methodology to balance texture, water-holding capacity, and mouthfeel. Mycelium-scaffold systems were engineered through controlled fermentation, substrate pretreatment, and fungal colonization to generate porous, interconnected networks that reinforce plant proteins and polysaccharides, enabling improved gelation and chewiness. Compositional analyses demonstrated enhanced protein density, essential amino acid completeness, and a favorable lipid profile when incorporating mycelial matrices, with biosafety assessments confirming the absence of pathogenic contaminants and acceptable microbial load. Instrumental texture analysis (textural profile analysis, shear force, and cohesiveness) revealed significant improvements in bite force, tensile strength, and springiness compared to conventional plant-based controls, closely approximating the texture of ground beef and chicken analogues. Microstructural characterization (scanning electron microscopy and confocal laser scanning microscopy) highlighted the integration of mycelial hyphae within the plant-protein matrix, contributing to network entanglement and reduced syneresis under thermal processing. Sensory evaluation through trained panels and consumer testing indicated enhanced juiciness, fibrous mouthfeel, and savory aftertaste, with acceptability correlating with optimized scaffold porosity and moisture-retention properties. Process optimization explored variables such as fungal strain selection, substrate composition (cyder- or lignocellulosic-rich waste streams), fermentative duration, moisture content, and cooking methods to maximize consumer-relevant attributes while ensuring scalability. Life cycle assessment and techno-economic analysis suggested a lower environmental footprint than traditional animal-derived proteins, driven by reduced land use, greenhouse gas emissions, and energy consumption, without compromising nutritional value. The study also investigated shelf-stability, antimicrobial packaging interactions, and potential allergenicity, providing a comprehensive risk assessment for industrial deployment. The resulting product demonstrates a tunable texture-nutrition matrix, enabling customization for burger patties, sausages, and mince applications, while offering avenues for valorizing agricultural or agro-industrial by-products as fermentation substrates. The findings contribute to the understanding of mycelium-protein synergy in plant-based matrices and establish a scalable, sustainable route to premium meat substitutes that meet sensory expectations and nutritional requirements, thereby supporting diversification of protein sources and advancing food technology innovations for future food systems.

The Problem It Addresses

---

Many plant-based meats struggle with texture, juiciness, and nutrition. Traditional methods may rely on processed ingredients and have high costs. This project looks for a natural, scalable way to improve structure and mouthfeel using mycelium scaffolds, aiming to lower costs and increase consumer acceptance.
