Abstract:
Growing demand for alternative proteins has spurred research into microbial proteins, particularly Fusarium venenatum mycoprotein (MP). Naturally encapsulated within rigid fungal cell walls, MP requires efficient extraction to liberate intracellular protein for nutritional and functional applications. High-pressure homogenization (0-120 MPa) enhanced cell wall disruption and protein extraction, increasing protein content (47.84 % to 71.22 %) and solubility (5.57 % to 79.60 %), while shifting to lower molecular weights without altering secondary structure. Furthermore, homogenization improved MP's essential amino acid scores and in vitro digestibility (75.17 % to 86.39 %) surpassing soy protein (SP) (76.25 %). MP solutions (6-14 %) demonstrated dysphagia-suitable viscosities (80.34-841.29 mPa·s), fitting both nectar-like (51-350 mPa·s) and honey-like (351-1750 mPa·s) consistencies, while SP solutions showed lower values (16.24-472.66 mPa·s). Interestingly, MP solutions at such high concentrations exhibited lower friction coefficients than SP, suggesting favorable lubricated oral perception. These findings position MP as an optimal protein alternative for dysphagia-friendly formulations, offering enhanced nutrition and texture.

- Protein content, solubility, molecular weight distribution, secondary structure, amino acid scores, and in vitro digestibility were analyzed.
- Viscosity and friction coefficients of MP solutions were measured and compared to soy protein (SP) solutions.
Main Results:
- Homogenization significantly increased MP protein content (47.84% to 71.22%) and solubility (5.57% to 79.60%).
- MP exhibited improved essential amino acid scores and in vitro digestibility (75.17% to 86.39%) compared to SP (76.25%).
- MP solutions demonstrated suitable viscosities for dysphagia diets (nectar-like and honey-like consistencies) and lower friction coefficients than SP.
Conclusions:
- High-pressure homogenization is an effective method for enhancing MP extraction and improving its nutritional and functional properties.
- Mycoprotein presents a promising alternative protein source for developing dysphagia-friendly food formulations with enhanced texture and nutrition.
