Abstract: A plant protein-based whole-cut fried chicken nugget is prepared from raw materials including peanut protein, wheat protein, seasonings, water-retaining agent, and coating flour in proportions measured in parts by weight. The preparation method of the plant protein-based whole-cut fried chicken nugget includes mixing the raw materials uniformly according to the proportions, subjecting to high-moisture extrusion treatment, boiling the resulted extrudate with water for an appropriate period, then coating with flour, placing in a frying pan at an appropriate temperature, and frying for an appropriate period. The plant protein-based whole-cut fried chicken nugget has a golden surface, a strong aroma, a crispy outside and tender inside, good elasticity and chewiness, no beany taste, high protein content, and rich nutrition.
