<p>Batter mixtures represent dynamic food systems with transformative effects on texture, flavour, and nutritional value across various applications, including fried foods and baked products. This review uniquely integrates a detailed classification of batter types—fermented, unfermented, hybrid, coating, and regional variations—along with their functional engineering properties, process techniques, and nutritional enhancements. It offers a scope not addressed in previous works. This evaluation of batters examines their components, operational traits, and broad uses in foods while discussing essential processing methods, including fermentation techniques, mixing procedures, and grain preparations. Hydrocolloids, particularly xanthan gum, play multiple roles in viscosity enhancement, stability maintenance, and nutrition implementation, whereas batters serve as platforms for bioactive compound delivery. This review demonstrates how process engineering techniques seek to refine particle dimensions and hydration levels, which leads to improved textural characteristics while extending the duration of food preservation. Although batters are commonly used in functional food applications, a knowledge gap remains regarding formula development. The novelty of this work lies in its holistic synthesis of technological, nutritional, and sustainability perspectives, linking food science with culinary practice to position batter mixtures as versatile platforms for healthier, culturally relevant, and environmentally sustainable products. This overview connects existing industry knowledge and combines scientific principles with culinary creativity, allowing batter mixtures to serve as the basis for creating healthier, sustainable food products.</p> Graphical Abstract <p>A comparative overview of fermented and unfermented batter</p> <p></p>
