Development of a plant-based meat analogue using ultra-processed vegetable proteins and novel binding systems to optimize texture, nutrition, and consumer acceptance.

Project Abstract

This study investigates the development of a plant-based meat analogue leveraging ultra-processed vegetable proteins and novel binding systems to optimize texture, nutrition, and consumer acceptance. The research addresses the growing demand for sustainable protein sources by engineering a product that mimics the eating experience of conventional meat while delivering enhanced nutritional profiles and reduced environmental impact. Ultra-processed protein concentrates and isolates from soy, peas, and fava are characterized for functional properties including water binding, emulsification, gelation, and texture-forming potential. A series of binding systems incorporating polysaccharide networks, alginate, methylcellulose, and protein-polysaccharide complexes are formulated to achieve meat-like fibrous structure, juiciness, and bite. Process parameters such as high-moisture extrusion, shear-cell texturization, and cooking stability are optimized through a factorial experimental design to evaluate texture descriptors (hardness, cohesiveness, springiness, chewiness), moisture retention, and microstructure using imaging techniques. Nutritional profiling emphasizes protein quality (amino acid scoring, digestibility) and micronutrient fortification to match or exceed the nutritional value of conventional meats, including essential minerals, B-vitamins, and omega-3 fatty acids, while minimizing saturated fat content. Fermentation-derived flavor precursors and aroma compounds are integrated to replicate savory meat notes, with a focus on reducing off-flavor compounds commonly associated with plant proteins. A consumer science component employs blind sensory evaluations to assess acceptability across taste, texture, aroma, and overall liking among diverse demographic groups, with data analyzed for segmentation and acceptance predictors. Life cycle assessment (LCA) accompanies the development to quantify environmental benefits over traditional animal protein products, considering metrics such as greenhouse gas emissions, land use, water footprint, and energy consumption. Safety and regulatory compliance are addressed through shelf-life studies, microbial stability, allergen management, and adherence to food standard guidelines. The research also explores supply chain implications, scalability, and cost analysis to determine commercial feasibility, including ingredient sourcing, processing throughput, and packaging considerations. Advanced statistical models are used to identify significant factors influencing texture realism and consumer preference, enabling a mechanistic understanding of how binding systems and protein types interact to produce desirable tactile experiences. Results are benchmarked against a control sample of conventional meat and existing plant-based analogues to establish performance parity or superiority. The study aims to deliver a robust, scalable formulation that achieves high consumer acceptance while delivering superior nutrition and a lower environmental footprint, contributing to the advancement of sustainable meat alternatives and guiding future product development in the plant-based proteins sector.
