सारांश	Rheometry is the scientific measurement of how fluids and semi-solids (pastes, gels, suspensions) flow and deform under applied stress. Using a rheometer (a precision instrument that applies controlled shear forces and measures the resulting deformation), rheometry characterizes the viscosity, viscoelasticity, and other flow properties of food products, essential for process design, quality control, and predicting mouthfeel sensations.	Quantitative Descriptive Analysis (QDA) is a comprehensive sensory evaluation method developed by Stone and colleagues in the 1970s that uses a trained panel to describe the intensity of sensory attributes in food products. QDA provides detailed, quantitative profiles of flavor, aroma, texture, and appearance, allowing researchers and product developers to characterize and compare products objectively.	Texture Profile Analysis (TPA) is an objective, mechanical method that simulates mastication (chewing) to measure the textural properties of food products. Developed by Bourne in 1968, TPA uses a texture analyzer (a machine that applies defined forces and movements to a sample) to generate a force-time curve from which multiple texture attributes (hardness, springiness, chewiness, cohesiveness, adhesiveness) are extracted and quantified.
