Global demand for sustainable protein has intensified amid environmental, public health, and ethical concerns surrounding conventional animal agriculture. Edible mushrooms have emerged as promising next-generation protein sources, delivering 19-35% protein (dry weight) with complete essential amino acid profiles and digestibility rates of 60-80%. Beyond protein, mushrooms provide bioactive compounds, including β-glucans, ergothioneine, phenolic acids, and vitamin D2, supporting immunomodulatory, antioxidant, and anti-inflammatory functions. Enzymatically derived bioactive peptides further demonstrate antihypertensive and antimicrobial activity. This review systematically examines mushroom protein properties, processing technologies, and product performance across three application categories: meat analogs, functional snacks, and beverages. Advanced processing technologies including high-moisture extrusion, ultrasonic-assisted extraction, and microencapsulation have improved bioactive preservation and digestibility. From an environmental perspective, mushroom cultivation requires 85-90% less water and land than animal agriculture, with 80% fewer greenhouse gas emissions. However, critical gaps remain: extraction efficiency varies 3-fold across studies, only 15-23% of commercial products are supported by clinical trials, and techno-economic analyses are largely absent. Standardized processing protocols, large-scale clinical validation, and harmonized quality standards are essential to establish mushrooms as viable, commercially scalable protein alternatives.
